Let's Build and Tune an Art Deco Speaker Cabinet
Вставка
- Опубліковано 23 сер 2024
- In this video we will merge two old, vintage speaker cabinets into one that has an Art Deco flair appropriate to be used with the scratch-built Tremolux amplifier featured in a recent video series on this channel. Once the speaker cabinet is finished, we modify the amount of back panel it has, checking the tone changes associated with each alteration.....until the best possible configuration is determined. Afterwards, we'll all take a break and go to a local hot rod show.

I find "speaker science" absolutely fascinating. Some speakers can play in a smaller cab, others need larger. Some can handle lots of power, others can't. Some benefit from a port, some don't, etc.
To me it's a lovely blend of art & physics, like a fine watch.
.......and I find that trial and error is the best way to fine tune the cabinets, Richard. Theory is nice, but nothing beats some good old experimentation.
not only are you VERY proficient in tube technology, you have a great sense of aesthetics and love for all the details. keep it up! greetings from switzerland!
Hallo! Willkommen aus Vereinigen Staaten!! Uncle Doug Verstärker videos bist der Hammer!! LG
Thanks so much, El C and Jack. We really appreciate the kind words :)
What I like about your designs,is how you always add a hotrod flare to it.Not to bust your chips ,but your stripe on the left side is a little off kilter.Lol,great job I guess your always on the hunt for vintage projects.Can't wait for your next.🎸🎶😎✌
Thanks, Bob. I noticed the slight misalignment in the video :(
very nice not only you replcated the look but the sound of the era. and your a car guy. i have a 1965 corvette convertable/small block/4speed/both tops/owned about 30yrs. a nice driver. played music in local bands all my life to this day. not a young guy but still kicking. appreciate your time enjoyed.
Thanks so much, DH. Your Corvette sounds like a really nice one......keep on kicking :)
Uncle Doug, I have been going thru your old videos and they are just amazing. While watching this one a thought came to mind. I pictured someone in the future finding your custom amps and cabinets, going through all the vintage catalogs trying to identify the model numbers, pulling their hair out.especually when you use parts from different cabinets to make one.
Greetings, Charlie. Hopefully, those historians will mistakenly classify our creations along with amps created by Ken Fischer and Alexander Dumble......making the owners rich ;)
I just about spit my coffee out with that "farts from a rented mule" comment. Pure Uncle Doug gold!
I strive for high-class analogies, Trebor. Glad you enjoyed this one :)
Great amp, great cabinet, great vehicles and great distractions. As always it's quality entertainment!
Thanks so much, Nusior :)
Looks just great. The pair is stunning together. Since there are no little kids around these days.... I might have passed on the screen.
Thanks so much, Dennis. The screen is long gone. It buzzed like a bee, especially with the new Jensen C12N.
She's a thing of beauty! What a nice set you've created. It's obvious that you have art in your soul, between this, the car work and the aerial videos it's really apparent. I find that the metal dust caps tend to make speakers directional. Unless the speaker says James B. Lancing, you want to get rid of those beamers.
FYI, those mounting studs are available from Antique Electronics and well worth the money.
Thanks for the info, John :)
It looks like a "horn". Tapped horn? Tuned for specific ranges? I commented twice. Lol This is inspiring.
Thanks, J&K :)
Sorry forgot to add that this video is superb,and your work equally so,Colin.
Thanks so much, Colin :)
Very nice Doug. You know, aircraft radios usually have two jack sizes for headsets. The phones use the standard quarter inch but the cord for the mic and push to talk switch use the smaller jack and plug. Makes it easy to know what to plug where.
Interesting information, Carl. I figured in this case it was to prevent the use of the Packard Bell cabinet with other gear.
If only they did this with computers - I'm forever plugging my headphones into the mic socket. On the other hand having another socket size makes life more complicated. Dilemma!
George Robartes: Back around 1910, or so, my maternal grandmother was a "Hello Girl." That's what they called operators in those early days.
Great job Mr. Uncle, I found a 15 inch Alnico last year and so now I'm in the mood to make it happen. Again, thanks so much for making it look easy and I'll do some research for a decent box size. Love the channel, you are a true craftsman.
Thanks so much, AT. Check to be sure that the magnet strength is intact. You can use a screwdriver. It should stick fairly strongly to the magnet. The magnet in the Hepper speaker was weak = flubbing.
You have very good taste, outstanding vision on all the work you do sir !!! Bravo👍🤗
Thanks so much, Craig.
You nailed the look. I am blown away to tell you the truth
Thanks, J&K :)
Absolutely stunning cabinet Uncle Doug! I really like the way it sounds half-back..
Thanks so much, BS. I appreciate your input.
Cool experiment! I didn't believe that the difference of the covers is that big. Especially between half closure one the back and the finally choose 2/3 one. Thanks for sharing!
I was surprised too, MO, which is why I wanted to share this info with you all. You're welcome :)
That speaker cabinet's a great companion to the amp! Those odd sized jack sockets look like the ones that Moog used to use for footswitches on their late 1970s synthesisers - I had to modify mine to accept a modern sustain pedal.
Thanks, Chris :)
Very awesome again. Cool little cab. You have a great eye for detail.
Thanks, GL :)
"It's an automatic...must have been a girls car at one time" I did not see that one coming Doug. I almost shot my drink through my nose. Beauty cabinet and amp btw.
We used to say that about Corvettes with automatics, air conditioning, power steering, etc. since most guys only cared about going fast :) Thanks !!!
I have the same Ampro cabinet. It is complete and has the back/door. The covering is in rough shape. This turned out really nice. Can’t wait to hear it with the better speaker.
Thanks, T :)
Ampro speakers are always amazing whether magnavox or Jensen, somehow I still felt bad to see the empty gutted Ampro cab
What a great looking combination !!
A worthy pairing for the Art Deco head.
Thanks so much, SP :)
The amp and cab are so gorgeous that it barely matters how they sound! (Duck and cover) I think you're right about the sound of the split back panel. I'll be building a 4 X 8" cab fairly soon, so I'll try some variations, but the split seems to have sound benefits over the closed and opened versions, and it's definitely more mechanically sound than the open.
Thanks, Mark. The idea of a 4 x 8" cabinet is very appealing to me. I recall being astounded by the great tone from the multiple small speakers in the Electromuse (previous video). The back really does need to be open for guitar use.
what a nice match for the art deco head! not just a nice build but a clever test on the different back types! rock on uncle doug! there's always smt to learn within your videos!
Thanks so much, GG :)
Hi Uncle Doug--nice job as usual. Speaker cabinets can often benefit by being stuffed with ordinary polyester pillow stuffing, which, acoustically speaking, makes the cabinet larger. Filling to a density of 1/2 to 1 pound of stuffing per cubic foot of enclosure is usually about right. Not only will the polyester fiberfill make the cabinet larger, it will also result in a smoother sound by reducing standing waves in the cabinet.
Thanks, R. That's a very interesting suggestion. I never realized that reducing the air space would make the cabinet behave as if it were larger. It seems counter-intuitive, but I trust your opinion and may well try this.
Love that Art Deco speaker and that grille!
Thanks, Cafe :)
Man that's amazing! You know I think it would be cool to build a little champ amp in a vintage Titan heater. I remember sitting in front of one of those as a kid. As always thanks for the fun video.
You're welcome, MW. I recall the Titan heaters and agree that it would be a great cabinet for a scratch build :)
Thanks Doug . I've wanted to do these experiments for years but haven't ever got round to it .
It all stems from my tendency to not believe what I'm told......only what I actually see and hear, FG :) It's a lot of work, but it sure cuts out a lot of BS.
wow who would have thought merging the two of those speakers would come out with such a great look. You have outdone yourself again Doug. Definitely the split 2/3's back sounded the best to me as well in your demo.
Thanks so much, Larry :)
Just like your video's Uncle Doug! And another nice project You did on the amp and speaker cabinet.
Thanks so much, Frank :)
I think you made the right choice on the 2/3 back, and if someone wanted to, they could just take off the panels for an open back. I'll look forward to hearing the amp played through the higher quality speaker, when it arrives. I dig the beautiful art amp aesthetic, very tasty looking, and I'm sure the sound will improve with the new speaker...!
Thanks, David. I have already installed a Jensen C12N and the difference is huge. You will hear it soon.
That is a really nice Art Deco look for that speaker cabinet. A great visual match for your custom amp. I am always impressed by your eye for aesthetics and your craftsmanship.
Thank you, Stanley. I appreciate your kind words.
Thanks for this video, I am building my own 1x12 cab with an Eminence speaker and wondered about the back. This gives some great information and I'll be doing a little experimenting on my own. It will be a stained wooden cab, I just wish I had such a good looking grille. Thanks again.
Glad I could help, Ken. Good luck with your project.
Beautiful classy chassis! I'm diggin' those gold stripes with the fancy grill.
Tres Chic! Magnifique! You are the tube amp freak!
Wow.....thanks so much, G :)
That is a nice package set up. Great job.
Thanks, Hack :)
An awesome project. You,ve got my imagination going strong.
That's great to hear, Russell. Let us know what you come up with.
@@UncleDoug i,ve been researching speaker cabs. Have you seen bill fitzmaurice designs? Dumble does an oval cut out on the back that he calls a tuned cab and the forte cab is interesting . Closed back but ported on top sides and bottom . Very interesting. Avatar resurected it. I,m a drummer but i love amps and guitars.
?
I have seen several of his designs and find them to be very original and interesting. Whether they function as well as they look.....I'm not sure.
Absolutely magnificent. Uncle Doug you truely are an artist. I love your work, Thank you
You're welcome, Claude. Thanks for your very nice comments :)
Awesome job. I like the gold pinstripes. Can't wait to hear it with a good speaker. A coordinated, tilted amp stand should be your next shop project. Elevating the speaker cab will improve the sound and look cool.
This is the best channel on UA-cam. Imho Always look forward to new videos from Uncle Doug.
Wow, thanks so much, Ray. The new Jensen C12N arrived today and it makes a huge difference. You'll get to hear it soon. Thanks for the project suggestion :)
That is one very good looking amp, Uncle Doug Sir!
Thanks, Mats :)
Beautiful. I got a new amp and speaker for Christmas but want to build a art deco 2x12" speaker cab and eventually a new cabinet for my amp. 😁
Thanks, Craig. Best of luck with your project.
Cool amps and hot cars. Another A+ project, Doug.
Thanks for giving the Hepner a very complete and fair shot. I've seen them on eBay and have been very tempted to try one, but I almost never see anything about them mentioned in guitar forums and now I know why. Too bad though because the speaker looked very promising. Thanks again for sharing your knowledge.
Thanks, Randy. It did seem like a really good speaker but I don't think it can handle the strong bass tones from a guitar. You're welcome.
I do like it. Have fun with it uncle Doug
You too, Dwight.
The cabinet looks great! I learned something new today. It makes me want to experiment with a cabinet I have. Thanks!👍😎🎸🎶
Thanks, DM. That's good to hear. You're welcome :)
@@UncleDoug ☺
Wow, I love what you did with the amp and cab, they look incredible. As far as the sound test goes- there are just so many variables that make it difficult to determine what your whole rig is capable of. But I think it's safe to say that a high quality guitar speaker is going to perform better than the vintage one you have there. And I just thought I'd mention that I have modern 12" cabinets that are about the same size as yours, and with a completely closed back and Turbosound 12" speaker they sound very good to my ears.
Thanks so much, G. I have already replaced the speaker with a new Jensen C12N, and the improvement is overwhelming. You'll get to hear it soon.
Volkswagon: My brother and I rebuilt dozens of those "pancake" engined models. They came in sedan, fastback, and wagon styles. I remember hauling many engines and parts in my old Willys Jeep. Most had to be converted to carb power from a really trouble-prone injection system whose "computer" would fail if you looked at it wrong. Lots of memories there.
I believe the one in the video had been converted to carburetors also, Ray.
another class A video!
I seem to get distracted more easily these days,
but they're okay by me!
Thanks, YRU :)
Wow Uncle Doug, just wow!!!
Thanks, Jason :)
Fantastic stuff there Uncle Doug, you never fail to deliver.
Thanks, John :)
Yeah that cab is very interesting. That back porting would make the sound projection more focused but still mildly 3D sounding.
Thanks for your input, Russell.
Luv that Post-it labeled Uncle Dough and Jack 😀 on the back panel in the 'quick comparison' ' section. 19:25
I enjoy your vids. Great stuff.
I think you should make a vid explaining what an impedance really is (frequency and time domains) and how to relate to rp 'tube constant'. It might be usefull for most of your viewers.
Thanks so much, Dr. S. I did go into detail regarding impedance vs resistance in several previous videos, but will definitely keep your suggestion in mind.
Bad Ass !! Thanks man! Such a cool video to watch. great craftsmanship and Tech work.
If I had that rig , I'd imagine I was playing with Duke Ellington or Django R.
That set up is great!!
Wow, thanks so much, 122M. I really appreciate your nice comments.
Nicely done, it looks really cool. Nice cars there also... Thanks for sharing!
Thanks, Daniel :) You're welcome.
@@UncleDoug would it be possible to make a video about how to delay or soak the power surge on diode rectified tube amplifiers? I once revived a diode rectified Vox AC50 which use to have a "brimistor" but some previous repair left a shunt in its place. It would consist on a filament and a bi-metal strip to delay the B+ until the tubes get warm.
26:12 I need to attend more car shows. Great video, Doug. Next time you do a cabinet, you should try the hinged back door thing so you can get the best of both worlds.
No kidding, Brad......but we'd probably both end up single and penniless :) I recall a video you did a long time ago with a hinged back door that made a big difference. I still have the back door for this one and may give it a try.
You could put a motor with a cam and have the door with a spring open and close and give you a wah effect physically. :D
I love it.....but at high speeds, it might just fly away :)
Leave it to Brad the Guitologist to be the comment calling out the 'distraction'! Really nice video Doug, the amp and cab look great!
I'd love to see the expression on a cop's face when you roll up next to his cruiser in that yellow '33-'34 Ford. Kind of an "Oh, sh . . . ! " moment on his part.
.....and it was the one day of the year (like in the horror movie) when you could do anything you wanted and get away with it.
This looks great and sounds very nice with your tuning efforts!
Thanks, David :)
Great video Doug, can't wait to hear the new speaker when it comes in. The cab looks good too.
I spent the day re-doing the cabinet, PC, and installing a new Jensen C12N. The difference is huge :) You'll see and hear it soon.
Storms like that are called "turd floaters " in these parts.. Nice job on the cabinet!
Thanks, PV. I saw some float by during the rain storm :)
Another excellent presentation, thank you UD! I agree, I think replacing the Hepner might help the tone. And for me, the comparison may have been clearer if the straight on recordings were presented in sequence, followed by the side on recordings. But what a lovely looking cabinet you have produced through a sense of style, and judicious salvaging and resurrection of (?) discarded items. Well done! PS, can I disqualify myself from any remote possibility of success in the StageRight prize draw - the Trans Pacific postage would be crippling!
Thanks so much for your very thoughtful comments, Cass. I have since changed the exterior of the cabinet as well as the speaker. You will hear and see it soon.
Nice. Once again you have inspired me.
I just got a Bell and Howell Jensen re-coned…picked it up today! Now I want to load it into the old projector cabinet and have a sattelite for my 1962 Brown Deluxe. Boxy? Probably but in tandem it might sound great.
Thanks, Jensen, that's good to hear. If the cabinet is open-backed, I doubt that it will sound "boxy".....but you'll have to experiment just like I did.
Uncle Doug fine job sir. I can only watch and learn as I am not in the same league. Don't get mad but the left pinstripes are not square. Any speaker in that box sounds good but you're new one on the way will be awesome. Thank You for the great video.
Thanks so much, J&B. No problem.......I noticed the disparity while watching the video :) I just installed an new Jensen C12N and the difference is huge :)
Thats a beautiful cabinet
Thanks, Caleb :)
An SUV with big wheels (18 - 24") reminds me of an old covered wagon! :-)
Yes, the dreadful "Conestoga" wagon look......to be avoided at all costs.
A very neat project! I agree the 2/3 split has the best sound to what I hear on my headphones. The VW is darn nice and either one of the coupes would work for me.
Thanks, Andrew. I'm glad someone heard it the same way I did. As I get older, I am beginning to distrust my own faculties :) Yes, the VW was a really nice car, but the blown yellow coupe is more my speed (pun intended).
Nice one, and very beautiful style.
Thanks, Marcos :)
Great job, the silver Ampro lettering ties the two pieces together nicely. I would like to see how the two pieces look when stacked up piggy back style. As far as speaker directivity, directionality, objectivity and acoustics are concerned the variables are countless and third party opinions are tough. I read that when sound engineers asked Mr. Marshall how he calculated what size cabinet to use in his famous 4x12 model 1960 speaker, he responded, "I just used used the smallest box that would hold four twelve inch speakers.
Thanks for the positive comments, Paul. You're right......it's all subjective, but I do think that a partially open back seems to work best for guitar, and agree that huge cabinets are simply not necessary.
Fantastic job! I agree with a speaker swap. But, love the cabinet.
Thanks, Nick :)
My favorite speaker for all types of amplifiers is the WGS Veteran 30.
So nicely done!
Thanks so much :)
Great video Doug about as hand made as it gets should command big bucks if you deside to part with it
I do eventually part with virtually everything I build, John, so let's hope you're right :) Thanks !!!
Man, I'm still diggin' that Amp. And what a great accompaniment piece you've made for it with that speaker. I mentioned that I've 'concepted' an art-deco style stereo tube amp. I'm glad I'd already sketched it out because I'd find it difficult not to let elements from yours creep in ! Great job (again) Doug... always an inspiration !
Thanks so much, CA. Best of luck with your stereo amp.
:) Seems I have more ideas than time these days. Most "garage" hobbies are going into hibernation for a bit. Came home to 2" of snow on the lawn tonight. Soldering with mittens on really sucks.
Started dabbling with Transmission Line speaker designs though, folded horns and such. Trying to muster up every bit of efficiency to pair with an SE triode set-up. Lots of math, lots of uncertainty, R&D, trial and error experiments... should keep me outta trouble over the winter. :)
Beautiful and great sounding amp! Love your channel Uncle Doug.
Thanks so much, David :)
I have made a 1 x 12 cab from some thin 1/8" ply . And I think that sounds good because it resonates like an acoustic guitar .
That's an interesting idea, FG. I guess the entire cabinet radiates sound.
Beautiful work as usual Uncle Doug. Love your videos.
Thanks, RD :)
Oh...tin dust cover. That'll help with treble some...but probably just straight out in front of the cabinet. I may be all wet, but I think that's how it will work. Wow! What a difference
in directionality 'tween the three back options. And I agree the open 1/3 in the middle sounds best.
All was so great at the car show (including the distraction) until the blue Chevy pickup. I agree...put some real wheels and tires on that beauty. The Yellow Ford...I'm gonna say '34
judgin' from the grill and the suicide doors and that windshield open like that...needs a rodent and small child screen on that intake though(8-). Thanks a heap, Uncle Doug. Great
video all the way around.
I agree with all you said, Tom. Thanks !!
Great work again Doug. My only nitpick is I think silver rather than gold and perhaps also painting the Ampro logo blue would have been slightly more aesthetically appropriate but, regardless, still an outstanding job. Congrats.
Thanks, 45C. You'll be glad to know that I worked all day to convert the speaker grill and stripes to polished aluminum and silver. You'll see it soon.
Awesome, let's hope it gets the Jack and Ollie sniff of approval!
They loved it !!!
Coolest dude on UA-cam!
Keep em coming Doug!
Thanks so much, BK. I love your screen name.....it fits me to a "T" :) We will.
The two look great together but I think I would have went with painting the grill and the stripes silver to match the head more also if you omitted the top handle and put handles on the sides you could then set the head on top
Actually, the head fits perfectly on top since the handle is very low profile. I should have included a view of them stacked. I really considered going with silver, Doug, but couldn't resist the gold. It can always be changed when I replace the speaker.
Oh okay well that's cool you can still stack it....yeah I would have like to see it silver to match the head, you did such an awesome job on that head it would have just been icing on the cake if the speaker matched the head completely you could always put some brass on the head to draw the colors together
I Agree BUT The Gold looks equally as good However that being said the two colors should be matched- Gold OR Silver Like I said I can not make up my mind I Really like them both!! as longs and they match-The head kind of reminds me of the passenger trains from when they were at their Peak! Looks GREAT yeah ok SILVER Top and Bottom is my pick_ GREAT WORK AS ALWAYS!!
Lol, why not mixed metals? Brass, aluminum, stainless steel, nickel, gold, copper... let's just get everything common in electronics on here, HAHA!
Thank you all for your suggestions. I am tending toward changing the cabinet to polished and matte aluminum finish. So stay tuned :)
Beautiful Uncle Doug!
Thanks, Dave :)
Great video Doug! The cabinet looks great. I have one... I replaced the Hefner with a Ted Weber 12A125S alnico speaker. You've made me want to cut out the middle third.
Thanks, FT. You might give it a try......I think it really improves the tone.
Another great video! Passed out to your phase inverter video and woke up to this :p *edit* watched for the cabinet, stayed for the cars :p
Thanks for binge-watching, YT :)
Stirling work, as usual, Uncle Doug. Classy!
I have a request.
I think you might be using the same guitar to test each finished amp.
Would you be prepared to do a rundown on it, Uncle Doug style?
I've been an avid follower of the 'Uncle Doug explores the desert/anywhere interesting' and the 'Uncle Doug prowls the car show' videos - with your flair for presenting I think you'd smash a guitar review out of this park and into the next one.
Or, for extra comedy, you could do one on a tennis racket for next April Fools day.
Whenever you release a new video my day is improved. Thank you.
Wow.....thanks so much for the very nice comments, PD. I do use the same guitar and shop speaker for every video, and have for many years. The guitar is a 1980 Vantage V-695 that I rescued from a pawn shop years ago for a pittance, and found that, after doing some repairs, it was my favorite guitar in the world. I have had and sold a bunch of high-grade Fenders and Gibson LP's, but have always kept the Vantage. It's like an old friend that never lets me down.
Superb work again , I do have to agree with previous comments that silver would match much better than , it seems to clash with the wonderful amp you made , but what fantastic work
Thanks, Shaun. I may still convert it to polished and matte aluminum with silver stripes.
muito criativo e ficou lindo modelo obrigado por esta publicação Sul do Brasil
Você é bem vindo, Jorge. Estou feliz que você tenha gostado do vídeo.
Looks awesome! Sounds good too.
Thanks, Greg. Just wait until you hear it with the new Jensen C12N :)
I love it! You've got lots of great skills, craft wise and art wise :D
Thanks, CM. I appreciate the kind words.
beautiful cab. Simpel shortcut but a good one. 😊
Thanks, Dr. Z. Sometimes the simple way is the best way.
Great job Doug
Thanks, Jeff :)
All of my Solid state Guitar Practice Amps have a 1/3 back cover. Kinda tempted to try tweaking it.
I so want a Hotrod truck.
A little more back door (just like cowbell) can make a difference, Leland. Amen to the hotrod truck. Every amp lover should have one :)
Looks great! "Farts like a rented mule" Ha! Haven't heard that one before. Thanks for the videos!
You're welcome, Frank :)
Uncle Doug, I like your eye for design. We agree that modern giant wheels don't look good on older vehicles. Although I am fine with a 16 or 17 in the right style and tire combo. Thanks for the followup with that VW owner! Happy to see the engine bay as clean as the exterior. That's not always the case. I scored an Arvin hi-fi amplifier on the bay today. I saw it randomly at 99 cents with 30 minutes left. I couldn't let it go for that cheap, so I picked it up. No clue what I'll do with it, probably fix'er up original, find a cheap record player and ask to borrow my mom's copy of Inna Gadda Da Vida :)
Thanks, Andy. I agree that 17's on the rear and 15's on the front can look just fine :) You're welcome on the VW. Congratulations on the new acquisition. See if your mother has any Ultimate Spinach or Vanilla Fudge albums....good stuff.
I will check! I had to look them up. If I were a betting man, I think my mom might say those bands were too far into the acid rock spectrum. I'm thankful she saved her collection from the 60s, there are some iconic records there... Tommy, Beatles, Stones, Cream, Iron Butterfly, etc
If she liked Iron Butterfly, she probably liked the other two also :)
very beautiful😊😊😊
Thanks for watching :)
Nice dovetail with the Amp build ! As you rightly mention, trying to judge speaker quality in a video with camcorder microphones is a crap shot at best although I use pretty reasonable playback speakers at home. The quality of most viewers probably varies from 2X2 desktop speakers to systems that are played in their high end home stereo components.
I would offer the following comments and are both personal observations. The speaker came though on my system as very bass dominant and frankly sounded like the dedicated purpose, organ speakers. My second thought was since you went with the Gold trim on the speaker cabinet, you might want to see if there is a local anodizing company that could match the amp aluminum pieces to go that extra step ! But as I'm fond of saying, it is easy to spend other peoples money....
You've been knocking 'em out of the park recently with your builds and I enjoy them and share your humor of the world as we stumble through it.
All the Best my Friend, to you and Jack
jagjet
still waiting to get a look at that tube cash … will advise ...
Thanks for your excellent observations and comment, Robert. I'm thinking of stripping the Ampro grille and going with a matte/polished aluminum finish, and silver stripes. We'll see :)
Great video. Thanks.
Thanks, Will. You're welcome :)
The speaker cabinet came out great! All it takes is skill and imagination to make something good happen. Your creative ideas are always intriguing. The overall sound is OK, but it lacks that certain tone that's needed for a guitar. I think putting a Jensen Special Design 12 in the cabinet with the split back may be the magic (Fender) formula! It's true about a sealed back cabinet creating good forward projection, but not much on the sides or rear. Also, a sealed enclosure makes the speaker stiff sounding and less efficient, and it will require more amplifier power to compensate. You could also try to install a circular vent port with a full back, but that's more for Hi-Fi applications rather than guitar/instrument use. Usually speaker enclosures are designed around the parameters of a particular speaker using the small Theile parameters, (SPL, free air resonance) etc, but I've heard many good sounding enclosures built by trial an error! I'm curious to hear the outcome when the new speaker arrives. :)
Thanks, Frank. The new Jensen C12N arrived today and is already installed. It makes the poor old Heppner sound even more like a rented mule. I had to leave off the vibrating screen behind the grille, and add felt to both sides of the handle to stop it from vibrating. It's a monster :)
Nice sound!!
Thanks, Robert :)
Howdy. A funny episode.
I thought I might join the Amp. Wars so I hooked up my DIY stereo 4xKT88 PA. Then I played a few AC/DC tracks.
What happened ? My kidney stones got on the move.
Flippin' painful, but luckily I have prescription painkillers. I just might suggest my doctor AC/DC through tube amp.s as an alternative treatment ...
Regards.
Press your kidneys against the speakers, set the volume to 11, and vaporize those stones, Eugene.
LOVE THE ART DECO STYLE ! Thx uncle doug n jack . what about electro plating the amp trim gold, top and bottom side stripe gold middle 1 staying silver or making a spare trim set in gold color somehow to match? It's easy for me to suggest it's just word's but work for you. lol hope you have a great day. Im batting down the hatches here in va. to see where they are going to steer the oncoming storm's.
You're welcome, Ken, and thanks for all the good suggestions. We really wish you the best with this hurricane.......may it pass quickly and will little damage.
Awesome job as always! Great stuff!
Thanks, Bill :):)
I'm not sure if you still have this setup, but I would be interested to hear how it sounds if you pack the enclosure with poly-fill (available at your local Joanne Fabrics or similar). Start with a light pack and increase the amount until it's semi dense with fill. That should cut the boxiness sound down and bring out the lower end.
Thanks for your input, S-L :)
And I was just about to go to bed.......its 11:53 pm here lol......oh well its only another half hour I guess ;)
Thanks for staying up, Harb :)
Well as expected that was worth it ! ......quiet amazing how well the change in tone was herd on camera when you went off axis to the speaker......be interesting to hear the difference with the new one when you get it.......ok off to bed now lol.....got a big job on tomorrow so better be awake for it ;)
We're glad it was worth watching, HEL. Yes, I was surprised by the significant difference off-axis......much greater than I would have expected.
