That sounds fun. Here in the US, prefabricated kitchen cabs are so cheaply built. It would be so much trouble the seal and brace. Was it for the kitchen, or just the cabinet itself?

@DIYhyfy They wanted an easy quick solution for the cabinet. So they went to Bunnings ( Home Depot) and picked up a couple of flat pack cabinet modules.. They weren't intended to be hifi just party. As far as I remember they used Motorola piezoelectric tweeters . Great for nite clubs.

Admittedly the new version is 30% the cost.

Hi, unfortunately the business that sold this kit closed their doors a while back. I purchased the parts individually from Parts Express

This kit was relatively "affordable" around $400-500. A decent pair of ribbons cost that alone

@@DIYhyfy Fair Call, wasn't aware this was a budget build, Why not the Dayton Planar Air motion tweeters? Would go with the rest of the Dayton hardware!

In terms of sound quality, the Swans win that category. The 212s have a great sound, but the Swans are better for most music. With new xover mods, they really shine. For movies, and large rooms the 212s are more consistent. Off axis is more neutral.

It technically possible, but unlikely at the output levels they'll be used at. The designer used the sane material as well

This sealed enclosure is right around 2ft³. A sealed subwoofer like this can play well into the low 20hz range. Given enough power, this will play just about anything you throw at it. Sealed drivers also benefit from "room gain" allowing them to get a boost from boundaries.

@@DIYhyfy Why didn't you take the building proposal from part express with 120l (4 ft³)? How deep can you get with your case? It's about half of part express's construction proposal.

Hey, can't recall exact number on spl. Paul has most of the technical data in his write-up on his site. If you search "Paul Carmody Pit Vipers" it should come right up. As far as port noise, none so far at any level. I modeled the response myself since I actually changed the port diameter. Air velocity was a bit higher than the rule of thumb, but not bad enough to be audible in any listening I've done so far.

I've wondered about doing a wrap. I just don't have experience with it. Seems like it would be tough to do seamlessly.

Freakishly friable

It's a definite possibility, but these will be run at low output levels. Not a ton of air moving around

You're right about the passives. This would have been a good build to use them in. I also appreciate the ability to model, and then make adjustments in the real world. My concern with rounding inside driver openings is always material thickness. By the time I countersink a driver, it leaves little material left to screw into. But I do know it has many benefits. Thanks for the watch!

I like to live on the edge! Lol

You choose correctly!! Let me know how the build goes. 3-way is significantly more tricky to get right. Best of luck on the build! Thanks for watching.

@@DIYhyfy yeah I know, I have it layed out on xsim a couple of different ideas, it's going to take a lot of real world measurements. I was going to make my other a 3 but the money, it would have cost another $300 and it worked out great. But the next one hopefully will be better. But great job, that's an awesome speaker!!!

Lololol yes. I like my posts SNUG!

Hi, yes I've measured them. They are pretty darn flat. End Game? Maybe. Toid is doing a redesign as we speak, using a better compression driver. While these are great, I would personally hold off until he publishes the new design (soon). I love these, and use them everyday. For movies, and some music, you will want a subwoofer. Pro drivers like this won't dig down terribly low.

@@DIYhyfy thank you very much for the reply.

Tom! Who am I? What am I? Where am I? Not sure, but these do sound REAL good! Much better than expected.

Thanks for the watch! As for the inductor, I personally don't consider it a big deal, but would also prefer an air core. The problem is, large values (5mh) go out of stock very often. I needed to finish the build, so waiting wasn't an option unfortunately.

Thanks!

@@DIYhyfy you're welcome!

Off centering drivers is a great idea. It wouldn't be tied directly to distortion. Distortion is a product of driver non-linearity. This is handled in the crossover. Off centering the drivers would help with surface reflections. These reflections create nulls & peaks in the frequency response. Tying it more to tonality. Thanks for watching!

@@DIYhyfy You are right! with surface reflections ;) Love you work, I'm a Speaker DIY'er myself.

​@@DIYhyfy I think he was thinking of diffraction. But I am in the process of designing something similar, I am going to use MDF and then a 2" thick piece of maple for the baffle. That was with the 2" thickness I taper the top making it narrow with a 45° angle down to the woofer which I want to make wider. It's a little extra work and money, but I have been thinking about the best way. I was going to move them to the outside (t+w) and then I saw a pair like that and liked it. I have a pair of 2 way I designed with a 10" Dayton reference paper cone and I think that's the only woofer I found I could crossover at 1400 without breaking up and after hearing a 10" woofer you can't go back. It's the only way to listen to Aja

That's a tough question to answer. There a lot of great plans out there. Or if you design your own, the possibilities are limitless. SB Acoustics makes high end drivers, Purifi also makes excellent drivers. Scanspeak, and so many more. For me, most of the affordable kits & plans sound good enough, not to want to spend thousands on drivers alone.

@@DIYhyfy Thanks for the quick reply , I have got a few months to kill. Can you suggest something with a budget of around 3-4K. Something that I can build and call it a lifetime achievement. I noticed that you are more of a Wood/Design guy , if I may take the liberty to suggest ... then I will recommend to pick up learning CAD and some electronics. Both skills will go a long way with you.

As someone with little to no space limitations, they look like the perfect speaker. Well done!

Indeed, they're a pair

It's not technically possible to demonstrate the real sound through UA-cam. You would be listening to my room & the speakers. Not simply the speakers.

@@DIYhyfy That's a myth. With a pair of good microfones at arround 1m distance, you can have a pretty good idea of how it sounds ;-)

@@Pierre-Leloup Yeah, it's not impossible to get semi-realistic sound from a set of speakers on a UA-cam video... but it's really hard, and not cheap. I've tried several microphones and different ways of doing it and they all just sound off. I sometimes do it anyway just to have something to demo, but it's a loosing battle unless you are really set up to do this and know what you're doing.

@@zarboaudioprojects1430 Well go listen to what some very good channels can do like "Sound Sommelier" (I don't know what's his setup to record) or even better "HiFi Immersion" channel, they do recordings of really Hi-End setups using a pair of expensive microphones: DPA-4011 & Zoom F8n Pro. I'm not at the same level as these guy's but using a very good pair of SE Electronics SE8 microphones and a Zoom H6, you can do very good recordings without spending much money. You can listen to them on my 2 latest recordings on my very little channel. Source is even worse as it is from UA-cam itself ;-)

@@zarboaudioprojects1430 Wouldn't you need an identical setup to have an "honest" reproduction of sound? You can't recreate the performance of a Corvette in a Camry. Sadly, I own a Camry. Great car, just not a Corvette.

This is a huge misconception. Screws are totally fine to use. Generally in very high out subwoofers or PA applications where they'll be moved around a lot. In home audio, simply glue & clamps are plenty sufficient. The glue binds the mdf together very strongly.

@@DIYhyfy Thank you! I am generally a "glue and screw" guy when it comes to stuff like this, or at least brads. I figure if I'm going to build a cabinet and throw some expensive veneer on it, I prefer to have the extra insurance the joints won't come apart even a little. I'm a noob woodworker, so "belt and suspenders."

You have a good eye. Paul used 2.5" diameter. These are 2". I modeled the response to be sure there weren't huge issues. I couldn't for the life of me find 2.5" pipe.

@@DIYhyfy Yeah, most stuff is 2". Even rolls of stretch come on 2" tubes.

Lol

I had feet coming for them. Wound up finishing the edit before they showed up. The Gaias look pretty pricey!

@@DIYhyfy they are magic! I put a set of Oreas under my Focal solo 6 four years ago and haven’t touch them since! absolutely incredible! You could try these.

Yes, it sucks

Hey, I did wonder this myself. The inside of the pvc is damped with dacron, but the cap itself isn't damped apart from being rigidly mounted to the baffle. Paul Carmody used the same setup, so I just trusted his judgment. There's no audible resonance from it, that I can tell. Thanks for watching!

Considering the size of the PVC hood I would assume the resonant frequency is higher than the crossover point of the 12" woofer. On Paul Carmody's DIY speaker site, the frequency response of the woofer starts tapering off at 300hz. There might be some energy that excites it but probably very little to be audible.

Hey, sorry I forgot to mention it. Parts were around 400-500 all in, depending on the finish you choose. Based on the sound quality, I'd say they rival $2-5K finished speakers. Thanks for watching!

@@DIYhyfy Oh wow. That is an unbelievable value. That's going to be my summer speaker project. Thanks!!

Hi, damping and bracing are 2 different issues. Polyfill & insulation break up standing waves. Bracing reduces panel resonances.

Hi, the laminate is Formica. It's only used to cover joints. Hence it only needs to be used on the sides. (Assuming you've designed the joint to be on the sides only, like me). The primer is sandable rustoleum primer. I would recommend 2-part epoxy automotive primer for easier sanding, but it's more expensive in a rattle can.

Thank you for watching!

I thought it would!

@@DIYhyfy I like "Monkey Coffin" and enjoyed the slang reference.
