My Infinity speakers have 8 EMIT Front Facing and 1 Rear Facing Driver !!!! INFINITY QLS-1’s 👍👍👍👍👍 I HAVE HAD THEM EVER SINCE 1978 AND THEY STILL AMAZE ME EVERY DAY !!!!
4:58 - 5:10 is exactly what you get from Open Baffle Mid / Bass drivers as well. Controlled directivity is what it is all about... so I really don't understand your comment concerning Open Baffle Bass drivers (Sub-Bass drivers) for IF done properly (Legacy Audio, GR Research, Spatial Audio, Lexicon) it is simply Bass to DIE for! I have owned the Infinity 9 Kappa's when they first came out and I went from an Appartment :( to a converted Industrial building with an open floor plan and 10.5 ceilings and WOW what a difference the 9 Kappa's were in the new space. So Yeah, Open Baffle (any many Dipoles) need space to breathe, i.e. need space to do their thing!
I'm glad you didn't diss your neighbor (lol). I have bookshelf infinity speakers that I bought about 20 years ago at Circuit City and they blew anything else away in their music room.
I have a pair of Infinity Column II speakers, bought around 1978. I'm not certain, but this might be the first Infinity with a rear-mounted tweeter. Does anyone know? I demo'd them against a pair of JBL Centuries for several hours before choosing the Column II's. They seemed slightly more open to me at the time, which might have been due to the rear tweeters.
My mother has a pair of Infinity WTLC which I absolutely adore. As a living room speaker, they're amazing. They have a presence that carries through the whole house. I'd like to think the dipole drivers have something to do with really placing the sound in the room. This was a big impetus in my making a copy of the BD-Pipes full range speakers about 10 years ago. Gosh do I like them.
Peter Snell was also keen on rear-firing ambience-adding tweeters. The later Snell speakers designed by Kevin Voecks had switches to turn on or off the rear tweeters. I tend to turn off the rear tweeters, and even with Magnepans, I like them better with less of the rear-firing waves bouncing around the room - which means room treatments behind the speaker.
First off. LOVE the Infinity rs-iiib’s I pulled out of my dads storage, amazing sound after a re foam job, components made in the 80’s I think were just so ahead of their time and it’s unfortunate cds killed that R&D budget. I can’t imagine if Infinity, Denon etc. kept that track. I do dream of your infinity’s being the next upgrade I make in 5-10 years. Nothing in between. 😂 Side note, Apple trees and peach trees will give lots of fruit when they’re planted with other trees of their kind right next to them. Just a little something I’ve learned. 2 or more will do it.
Oh that takes me back. I used to manage a peach orchid that covered 250 hectares. We produced export peaches the size of large oranges which went to Asia and Europe.
Thank you! Just saw this. I bought a pair of Infinity Column II speakers in 1977 or '78. They really impressed me then, and I still enjoy them in 2023. It's kind of interesting reading thoughts about "cheating." I wonder what the guy thinks of multi-channel AVRs, Dolby, Atmos, etc.?
Years ago I built a speaker system from a design in speaker builder magazine and I decided to try putting a tweeter on the rear out of phase with very good results. All peerless drivers and hand built crossovers w air core inductors polypropylene caps. Then my x made get rid of them.
@@donalddeorio2237 I see😅 That sounds like a good plan.. Women like to make us guys get rid of things while they won't do the same with their stuff that we don't like..😅
Øystein. No way, my wife keeps making me upgrade her system because she knows how good a real system performs. Our HT system has spoiled her. My advice, choose your audio system components carefully, and your wife even more carefully. Replacing components is relatively inexpensive !
Electro-Voice implemented a rear tweeter -- with a higher crossover point and lower level than the front tweeter -- in their Interface A bookshelf speakers back in the early 1970s. I had a pair, and the effect of that extra tweeter was fairly subtle, but it did add a sense of larger image size and spacious ambience. IMO it's a good idea if it's done right.
Just outside of Hamilton, ON, we have the "Winona Peach Festival". Usually around the end of August. Unfortunately, not this year. Stupid covid. Beautiful peaches and AWESOME Cobbler! If you're ever up this way, check it out! (2021, hopefully).
Wonder what would happen if I pointed the tweeters straight up? Don't want to try it being I know if you turn the speakers sideways Infinity wanted you to take the Emit out and turn it so it's long ways again. Thinking being on their backs may cause real issues. But... the sound bouncing off the ceiling may be interesting.
Perhaps the Finest Example; may be 'Arnie's' "affordable /budget" speaker, from the mid-70's. It was a great success, for 'Arnie' & Infinity - the "2001". To best of my recollection, It had about the same general dimensions as a 'KLH 6'. It used a 10'' Accordion Surround Woofer ("RtR" ? ) and TWO 'Seas' Aluminum Dust Cap Cone Tweeters - One FRONT / One BACK. They left a great impression on me. Because during the "Jurassic Period" ; I sold Audio, for my livelihood. They were an immediate "go to" speaker for a Customer, "on a budget". I believe they sold for less than $300 a pair ... For the Customer - "Money Well Spent" ... They Sounded Great ... My colleagues and I sold a "S#@T - Load" of them ! ;-)
Isn’t a rear tweeter a bit of cheat? I’m know it makes the speakers sound great - space, air, imaging - but the music didnt “sound” that way when it was recorded. Is accuracy an issue?
All the rear tweeter does is effect the imaging and soundstage. As far as accuracy, I don’t think adding the tweeter would do anything bad to the sound
@Vincent Gizzi You are 100% correct. The additional rear firing tweeter adds only time smeared distortion. Albeit, an ear pleasing type of distortion. If you want a truly accurate soundstage, then you should not use a rear firing tweeter. But most people, including audiophiles, are not purists. A visit to Best Buy (and similar stores) often reveals TVs with the brightness turned up. It catches the eye. It is not natural. But a lot of people go for it, and use that setting at home. When I visit one of my friends, I find his TV to have an unrealistic display. But it does look very good. It is his TV, and it makes him happy. I see it as having too much salt on your fries. But a lot of people love to over-salt their fries. I tune my TV to look natural, and my stereo, too. Cheers!
Everything is a cheat. From the mic it was recorded into to soundboards, compression, auto tune, time aligning, reverb, EQ, recoded on format... I don't understand the word "cheat" in audio. Isn't the real goal is for it just to sound as good as it can? For some of the stuff people do, putting tweeters in the back of a speaker for a tiny gain is not earth shattering.
@@finscreenname Why did you write that you do not understand the word "cheat", when you gave 7 examples? I agree with you that putting tweeters in the back of a speaker is not earth shattering. So let's both gang up on the person that made that claim. Please point him out. I also agree with you on all of the crap that the studios do. I wish that they would refrain from all of those practices, unless a specific need arises. For example, use autotune sparingly, to emphasize a crescendo, or some other interesting sound image. But it should be the exception -- not the rule. All of the EQ, and reverb, and compression, etc, ruins the music. I seek out music that minimizes the amount of the graffiti that the mixing and mastering engineers color the sound with. And I seek out audio gear that does not compound the problem. I cannot do anything about the music that is already contaminated by poor studio work. But I can keep it from getting even worse. I will not purchase a speaker that has both a front and rear firing tweeter (unless the rear firing tweeter can be toggled on and off). Cheers!
@@NoEgg4u I'm not busting your balls. I'm agreeing with you sarcastically. My point was that to me there is no such thing as a cheat in the audio world even though there is many here that would disagree with me. I use a EQ on almost everything I have. I hate all the 1khz many systems have. Easy fix with a EQ but a lot will say that's cheating. I didn't know there was rules in this audio world when I bought the first one in 1984 that is on my main system today. I'm corrupted for life now. You will never get me to listen to what someone else thinks is the way something should be, Copper!!!
Most don't but many have 2 (front + rear) tweeters but many also have had some models with it. Even Cerwin Vega has had models with rear tweeters. Don't know what Cerwin's point was since they are basivly just good party use anyway but :P
Definitive Technology routinely uses tweeters on the front and back of their towers. Albeit the tweeter and woofer on the back is operating at 50 to 60% of the volume as the front drivers.
@Art DIY I bought these because of Lukasz Fikus, the brains behind Lampizator. I followed him when he was a DIY blogger before he started his company. I have owned two of his DACs, both fantastic. He also designs speakers for the do it your selfer, and he has made his favorite design into a commercial product, the Fikus Electric P-17. The problem is, he only sells it in Europe, so I decided to build my own. The best part was that I already had everything I needed except for the tweeters and the crossover. They do not call attention to themselves, and I can hear an extra 2khz with the ribbons than I can with my electrostatics, which are good to 20k. They are good from 1khz to 40khz, so I can, and have, run them with my 15" woofers in a two way system. I prefer the speaker as a three way with a big Altec horn as the midrange.
Pls focus on useability of home theater systems when combined with stereo. Switching, connection issues are horrifying at times. Industry needs to focus on this. What is ps audio doing?
Pre amp with home theater by-pass combines both systems into one. I use a Marantz processer for ht and emotiva for 2 channel. The home theater goes through the by pass on the emotiva but still uses same speakers and amps just different pre amp/processer
@@carlosoliveira-rc2xt I'm using a ribbon dipole .I've added a small dome tweeter,on the same axis but firing inwards.It cuts in at 7000 Hz.The gains are clear increased depth and focus. The sound is just great and not as you may think ie not just the treble but bass as well
One Apple is enough, if you know what I mean 😀 But seriously, isn't it wonderful watching your own plants bloom? My dad planted raspberries last year, and every single berry was just priceless and tasted amazing :)
The addition of a rear firing tweeter is generally use for: -- overly damped rooms. -- producing pleasing phasey phenomena in its output. The additional rear firing tweeter could make for a more enjoyable listening experience, but know that it adds only distortion to the sound field, as its contribution is smeared in time. When I write "distortion", that does not imply crummy sound quality (speaker designers would not include it if it did that). Technically, however, it is distortion. Cheers!
NOT necessarily. For It's, a " case by case " situation. For example, If it's for a " super tweeter"; crossed in somewhere above 8k to 12 k . It could give more High Frequency extension, without Smearing the Top End of the Forward Facing Tweeter. Caused by the "Comb Filtering Effects"; caused by Not just a typical 6db order "x-over" But of Great Import is ; Is It's Placement on or in, the Speaker Enclosure. It's truly, " Location, Location, Location" ! ;-)
@@RoaroftheTiger If there is a front firing super tweeter and a rear firing super tweeter, there is no chance, none, of avoiding time smearing. There is no possible way for the same sound, being produced by two different drivers, one firing forward, and one firing backwards and reflecting off of the rear wall... there is no way that both sound waves will reach your ears simultaneously. The time smearing will not sound bad. It will probably sound very good. No one would design a quality speaker to sound bad. But it will be a form of distortion. For folks that pursue time aligned sound with zero distortion, they will not want such a speaker.
@@NoEgg4u Did I tell You to use the Example You just gave ??? I Wouldn't do that ! Why did You assume , I would ? Even, in the Infinity Speakers mentioned; I'm guessing the Front Tweeters are being Rolled - Off (Dependent on the Speaker Model, and It's compliment of drivers ; somewhere above 7 or 8 k or Much higher, 12 K - ??? ), as the 2nd one " kicks - in". All this, is an over simplification of Complex Variables. So there is NO - One Answer. But, the Tweeters ( and or a "super tweeter"), would be Time Aligned. There is little, or NO smearing" if the Alignment is Correct ( ONE Driver - Tweeter or super tweeter) The Alignment will depend on physical placement , oriented to the Other Driver's voice coils in the system "enclosure" as well as the appropriate crossover. It would Time Aligned and, in Phase. 'Nuff said.

A good shovel of lime on your apple tree fork it in next year you will get apples you won't know what to do with them except make cider do that for any fruit tree every 3-4 years
@@Paulmcgowanpsaudio yes not a spade full sorry only on a big tree, yours are small couple of trowels sprinkled around the base it helps because the soul is acid prevents fruit grow and protects against mites and bacterial infection in the soil, yes you can over do it. Trees are hardy things weeds grasses can be killed buy lime. Check your ph level of the soil alkaline neutral side is better for fruit trees. You could use potash what has lime in it what is a fertilizer. Just try with the one tree the apple tree if you're worried just a trowel of lime sprinkled around the base and covered depends how long those trees been there are they restricting in pots?
@@Paulmcgowanpsaudio ok. what you might like to do to your speakers using homes and a piston driver as your midrange coupler.? Get the midrange into the horn unit so it's like an eyebrow overlapping the driver slightly and the bump in the horn a nice Curve, this encourages airflow down into the driver reduce beaming not so much in the vertical axis better integration between the two, and not relying on the cross so much. If you look at dynamic flow with water you know what I mean air is a fluid and works in the same way. If there's a hump and water flowing over it causes the water to go down. Make your cabinets out of i said granite powder! but I think maybe a better material what would be cheaper slate fine powder and epoxy resins what is environmentally friendly, I getting a feeling that's what Wilson's using in their cabinets. Slate powder and epoxy resin. Another way is to have open cell foam between two pieces of material, on the outside quarter of an inch of MDF an inch and a half of foam and then hardboard the ones with the holes in it ,, usually these come quite thin 5 mm or so... but could be glued together 3 sheets holes lining up allowing sound waves to pass through the holes into the foam would work specially well on the front and back baffle. I think better would be to have the hardboard on both sides this will take way the boxy of the speaker. Just two layers of hardboard about 10mm thick either side of the sandwich, a thinner box is a better way to go you can still put some bracing in crucial areas to give it rigidity. Anyway there's some food for thought. See what your speaker guru thinks that ha ha

@@NoEgg4u Did I tell You to use the Example You just gave ??? I Wouldn't do that ! Why did You assume , I would ? Even, in the Infinity Speakers mentioned; I'm guessing the Front Tweeters are being Rolled - Off (Dependent on the Speaker Model, and It's compliment of drivers ; somewhere above 7 or 8 k or Much higher, 12 K - ??? ), as the 2nd one " kicks - in". All this, is an over simplification of Complex Variables. So there is NO - One Answer. But, the Tweeters ( and or a "super tweeter"), would be Time Aligned. There is little, or NO smearing" if the Alignment is Correct ( ONE Driver - Tweeter or super tweeter) The Alignment will depend on physical placement , oriented to the Other Driver's voice coils in the system "enclosure" as well as the appropriate crossover. It would Time Aligned and, in Phase. 'Nuff said.
Distortion is my favorite. Without distortion the Stones would sound like Judy Collins

vid starts at 2:36 and ends at 2:47. you are welcome.
@Fat Rat 11 seconds to reply. The rest is painful embellishment and nonsense. But I can see why he's a hero to such a simple numbskull such as yourself.
You haven’t been in audio for long if you haven’t seen a speaker with rear tweeters pal there all over the place Paul don’t care about your yard 🥴
ha. one word : Bose
another word... ipecac.
GET... TO... THE... POINT!
A good shovel of lime on your apple tree fork it in next year you will get apples you won't know what to do with them except make cider do that for any fruit tree every 3-4 years
Really? What does it do? I thought lime was used to kill things.
@@Paulmcgowanpsaudio yes not a spade full sorry only on a big tree, yours are small couple of trowels sprinkled around the base it helps because the soul is acid prevents fruit grow and protects against mites and bacterial infection in the soil, yes you can over do it. Trees are hardy things weeds grasses can be killed buy lime. Check your ph level of the soil alkaline neutral side is better for fruit trees. You could use potash what has lime in it what is a fertilizer. Just try with the one tree the apple tree if you're worried just a trowel of lime sprinkled around the base and covered depends how long those trees been there are they restricting in pots?
@@johnsweda2999 No, they're in the soil. Thanks for that. I have a lot to learn.
@@Paulmcgowanpsaudio ok.
what you might like to do to your speakers using homes and a piston driver as your midrange coupler.? Get the midrange into the horn unit so it's like an eyebrow overlapping the driver slightly and the bump in the horn a nice Curve, this encourages airflow down into the driver reduce beaming not so much in the vertical axis better integration between the two, and not relying on the cross so much. If you look at dynamic flow with water you know what I mean air is a fluid and works in the same way. If there's a hump and water flowing over it causes the water to go down. Make your cabinets out of i said granite powder! but I think maybe a better material what would be cheaper slate fine powder and epoxy resins what is environmentally friendly, I getting a feeling that's what Wilson's using in their cabinets. Slate powder and epoxy resin. Another way is to have open cell foam between two pieces of material, on the outside quarter of an inch of MDF an inch and a half of foam and then hardboard the ones with the holes in it ,, usually these come quite thin 5 mm or so... but could be glued together 3 sheets holes lining up allowing sound waves to pass through the holes into the foam would work specially well on the front and back baffle. I think better would be to have the hardboard on both sides this will take way the boxy of the speaker. Just two layers of hardboard about 10mm thick either side of the sandwich, a thinner box is a better way to go you can still put some bracing in crucial areas to give it rigidity. Anyway there's some food for thought. See what your speaker guru thinks that ha ha
Please go DIRECTLY to the point, you ALWAYS talk too much...
Thanks
