I like the next best thing, multi channel stereo, stereo music played back over 4 full sized speakers. Surround receivers or dsps allow you to calibrate for time arrival and change levels to adjust how up close the soundstage is, going from similar to headphones sound to more normal 2 speaker setup and anything in between. Just adjust the levels of the side/rear speakers. With preset buttons on the remote I can easily switch between listening to music or movie. Sound stage is phenomimal, puts you right in the music, even at low levels. You'll hear the tiniest sounds you missed with just 2 speakers. Setup is quite a bit harder and involves measuring mike and software for time alignmemt (or use built in function of the receiver but results can vary).

Back in the early '80s I had a quad system but, since it was hard to find quad albums I never bothered with the special cartridge, but I loved the four-speaker setup and so did all my friends and neighbors who partied in the back yard waiting for the special MTV show, simulcast on the FM station (since I didn't have a stereo tv), where everyone congregated around the tv and we were enthralled. Best times of my life.

Stereo was originally going to be 3 channels. A center channel & 2 side speakers. An old Citation tube amp I found & built ( the kit was probably circa pre 1957), and had a 3 channel switch, in anticipation of 3 channel stereo, which didn't happen. When Quadrophonic 4 channel sound became popular, some people had a speaker in each corner and sat in the middle of it all, with sound coming from front, behind and the sides. Many people had two speakers in front and 2 speakers further back behind them to get amazingly palpable depth; and it was capable of being more palpable. Some great albums like Dark Side Of The Moon were Quadrophonic projects, meant to be heard in 4 channel Quadrophonic sound. There are Quadrophonic reel to reel tape decks. Some only play back in Quad, like some Pioneer decks you can find used on ebay in the $500 and up range. There are second hand Quad reel tapes for sale there also. A Quad lp requires a 4 channel Quadrophonic cartridge. Koss made Quadrophonic headphones. I think they called them Phase 4+4.

To say "Stereo was originally going to be 3 channels" is only at best half true and certainly robs us of some history if we only think this. What you are likely referring to were the competing stereo capture and repro initiatives being led 1930s by British engineer Alan Blumlein @ EMI and by Harvey Fletcher at Bell Labs. Blumlein was a 2 channel proponent, Fletcher was multi-channel. Im rather sure Blumlein was first to the party, and either way, his way won out. That said, 3 channel summation from a 2 channel signal is something folks in the mid to late fifties were indeed playing around with, Mr. Klipsch has some papers from the time that talk about how to derive an LCR playback from a 2 channel source, mentions of it online are easy to find. Experiments like that (and likely some 3 channel releases of some type) meant stuff like that Citation amp was probably a fun bit of kit for its time.

The quad concept also is the foundation of the now popular "ambisonic" recording system. Spectacularly realistic renderings of the sound field experience or performance can be recorded and played back with these newly released microphones and 4 channel recording equipment. Ambisonic can later be decoded in everything from mono to Atmos where It is being used in recordings for cinema sound system reproduction. The big use is in the virtual reality devices where sources in the sound field appear stationary while the viewer moves within that space and gets cued by the source of each sound.

Some might say the 5.1 high res versions are better but I enjoy listening to those old recordings. I hear the engineer's zeal in their aggressive use of the rear channels. Maybe the problem some people have with any multi channel recordings is that they can put you on the stage rather having the performers in front of you. For truly great music I'm happy to hear it. 5,4,2 channel or even mono!

Most people do not have dedicated listening rooms. So they have enough trouble trying to find room for 2 speakers and the rest of the gear -- while negotiating the real-estate with their wife. Adding yet another 2 speakers requires more money (or far less capable speakers), and more space. This excludes nearly everyone. Add to the above the few songs are available in quad, and you have a very small demand for quadraphonic sound for music. For movies, as our host said, there is more of a demand. But keep in mind that few people have accurate reproduction of movies. The folks setting up for surround sound for movies likely have exaggerated bass, and if you played a well recorded song, it would not sound right. Such systems are not set up the way an audiophile would set up a stereo, and the speaker choices would rarely be high-end speakers. There are exceptions, for people with deep pockets.

An anecdote. I use a Sansui quad receiver to play my records and tapes. I think Sansui may be the only one that has a synthesizer for processing stereo signals into quad. I use that synth to play my stereo albums. It has given me the sound I have searched for all my life. That's no exaggeration. I stack the rear speakers on top of the front speakers in the basic stereo position, left and right. I call it enhanced stereo. Now the speakers I use for this are very specific. IDK how much this has to do with the way it sounds. I suspect a lot. JBL L36's for the front (bottom) speakers. JBL L110s for the rear (top) speakers. The difference in power handling between the speakers make the 110's a lot quieter. The bass of the 110s is weak, they're not great stand alone speakers. The front (bottom) L36s handle the most of the sound. But there's something about those L110s that really add to the sound. But It's not just the speakers. If I switch the Sansui to 2 channel sound, that great sound I'm getting form the quad synth goes away. But, also, if I turn off the 110 speakers the great sound goes away. I have demonstrated this to multiple people so it's not just me. I keep trying to get someone on KZbin to explore this. So far, no takers. I would love to see someone analyze this phenomenon.

In the early 70s I built a quad system using the Hafler method. This worked by taking the difference between L and R channels, and playing this signal through two rear speakers. (No special cartridge required).Some recordings were spectacular - others disappointing. The idea was that audience noise and reverberation often arrived out of phase at the recording microphones, so would be enhanced when played via rear speakers. Then Sony brought out a quad decoder chip and released specially recorded albums. The results were not bad, but did not justify the expense.
@jpatrickmoore5158 Жыл бұрын
You can still do the Hafler method, but you need an amplifier that can handle the load. The hot wire from the left channel goes to the hot input on the left rear speaker, hot right output goes to the hot input on the right rear speaker, and you connect the ground terminals of the rear speakers with a wire. At least theoretically, you could use switchable resistors to lower the rear volume in the line between the speakers. It's going to put an irregular load on your amplifier and I suggest that you don't crank your system too high. Using a second amplifier for this might be a good choice, rather than your pride and joy system.
@glenncurry3041 Жыл бұрын
I'm using the Hafler method right now. Except the matrix is done at the input. It's an old 4.1 channel PC speaker system and PC's don't have read outs anymore! So I Y'd the line out and fed the rear amps a differenced combo. Rear is pure ambiance. It can get deep at times.

Personally, I don’t think quad took off in the ‘70s bc most of us couldn’t comfortably afford it. The average adult at that time did not have oodles of disposable income, and decent quality stuff came at a premium. Sure, spending a few hundred bucks for something back then seems cheap now, but back then it was no joke. If you were lucky enough to own good stereo equipment back then, and could afford to amass a collection of music, you’d have to think long and hard about complicating that with setup issues, more amps, speakers, compatible equipment, and 4-channel recordings. It wasn’t happening. As Paul mentions, even these days, those that are fortunate enough to be able to enjoy premium home stereo or home theater, are few relative to the sum total. One must remember the variance in perspective in audio enthusiasm. There is a vast number of people enjoying audio through via IEM’s headphones, or near field listening with bookshelf speakers, and the list goes on. Even in terms of the multitude of ways the music is delivered to those transducers. And all the other “stuff” I didn’t mention. So it’s easy to see why opinions very so wildly these days regarding audio.👨🏻

I don’t recommend anyone one spending any money to do this, but if you can tolerate a righteous 70s horn section, give the album “Chase” by the band “Chase” a listen on a reasonably imaging two channel system. This album was originally recorded and mastered in quadraphonic, and, while what you will find has been mixed down to two channels, the result is nonetheless wacky and maybe entertaining.
@andydelle4509 Жыл бұрын
Quadraphonic audio was also introduced at a time when we didn't have the technology at a consumer price point to do it properly. In fact not until the 1990s with digital audio and DSP processing. The quad systems with exception of discrete quad tape all relied on analog phase cancellation or in the case of CD4, FM carriers with limited fidelity It just didn't work very well and on top of that there were at least two major competing formats SQ and QS. A Betamax and VHS rehearsal run! Although many audiophiles eschew these 5.1 synthesized surround modes, they are much better than the old analog quad attempts. But I do have a DIY version of the Hafler matrix on my music system. It's just simply a line level L-R circuit which is said to recover some ambiance. I have four small surround speakers on a mono amp for the rears. I do like it in moderation and it can be easily turned off as well.

Paul, you have many of your facts wrong! I believe your prejudice against any more than two channels is just plain wrong. Your way of thinking is typical of most audio "snobs", I used to work in a high-end audio salon, and we actually embraced surround for music. Let me point out your misinformation. Quadraphonics was not started by speaker companies. In fact, the folks at Vanguard Records started experimenting with adding the additional channels, using their own recordings to conduct their tests. Leonard Feldman, who was with Stereo Review Magazine at the time, was invited to hear these tests. His reaction? "I have heard the future and it works", he wrote. That was a pretty solid endorsement! At first, the only way to deliver quad sound was on open reel tape. Now came the daunting task of putting quad on records. Dynaco came out with their Dynaquad decoder, which was touted as a way to extract hidden information in stereo recordings. It used the phase differences that are present in practically any stereo recording, to create a surround effect from them. They also offered an integrated amp with their decoder built in. Their add-on unit was a passive device that only needed a two- channel amp to work. Dynaco also had an encoder for their system, but it only saw limited use. Electrovoice were also working on their "Stereo-4" matrix. CBS Labs, at the same time, were working on a carrier-based system, similar to what CD-4 used, but they couldn't make it work reliably. They developed the SQ matrix system, which was completely incompatible with EV's system. Sansui, in Japan, developed a matrix system that was more symmetrical in its approach, QS, but was close enough to the EV matrix to be compatible with that system. Unfortunately, it was still incompatible with SQ. JVC, in Japan, developed the CD-4 system to bring us a true, discrete quad record. Unlike the matrix systems, which could be played with any stereo cartridge, CD-4 required a special cartridge and stylus. The demodulator, needed to decode these records, was very finicky. Getting all of the adjustments perfect, which they had to be, was difficult. The matrix decoders didn't need all this adjustment, but they didn't offer the same degree of separation as a discrete system would. Further development brought them closer, but it would take an Australian company, Involve Audio, to bring both QS, and SQ, to discrete levels. This decoder, the Surround Master, is readily available today. It also decodes Dolby Pro Logic II, and EV. So why didn't quad succeed? Clearly, it was a technology ahead of its time. The confusion created by so many systems for records was too much for many music lovers. Quad went on the back burner until home theater brought it back. The idea of surround for music was still of interest to many. We saw Dolby Surround CD's, DTS CD's, multichannel SACD'S, DVD-Audio, and now Blu-Ray Audio. Interest in surround music has been revived... and it is the future, and it works! I hope I was able to clear up the mystery and misconceptions, both for you, and your readers

'Ole Audiophile to Paul: What Paul isn't mentioning is Quad was a better format for music but the know-how of correctly implementing it lacked. Quad barely was widely marketed until 1972.

Often, rock music was just to simple to remix effectively into surround, not to mention hiring a whole batch of surround engineers to create it. Add to that mess, one could barely ever find quad material for sale, record stores refused to market it for the most part. Thanx

I remember going to a quadraphonic sound demonstration by Sanyo at Earls Court London in the early 70s and it was awful. No dynamic range or even good placement of sound within the space wherever you stood or sat. Whether this was down to the demonstration area it was in or just that the mix was not really good or not I could not say but the Revox stand a few meters away had much more realistic and convincing stereo setup which was probably the best demonstration setup there that year. At that time it was difficult to find a good set of accurate sounding speakers. JBL speakers seemed bass heavy. Keff were still producing kit speakers and results varied. Good Tannoy speakers were huge and lacked a good mid range. Electrostatics had no real convincing bass. At that time I loved the Rogers LS35a s with a sub bass unit. They suited most British living rooms which were quite small and gave an impressive sound stage. I still think though, most people can't hear a difference between a mid tier system and a top end one or simply don't care about the nuances a more revealing system can give. Then there is the spouse problem. There is no way my wife would put up with my speaker system in our lounge. I am lucky and have a dedicated sound room but I think most households at least of my generation have lounges where the intrusion of disproportionately sized boxes along with quite chunky axillary equipment would not be tolerated by our respective partners. Also the average lounge in the UK is not that large.

@@bradesq9422 Brad, not to argue, but you might want to read some articles about how modern recordings are actually recorded, and how the recording engineers mix the multitrack recordings down for Atmos, 5.1, 4.0, and stereo. It's really quite interesting. If all that they did was two-channel, then that's all we'd be listening to. As for recordings in 5.1 (for example), there are many, many SACD's, Blu-ray Audio discs, and DVD-Audio discs that are quite readily available. They're discrete surround, meaning each channel is completely separate from the others. This means absolute channel separation. The SACD you have of DSOTM is a perfect example. Rhino Records have their QUADIO series blu-ray discs that will blow your mind. They just released four new (to Quadio) titles, from Black Sabbath, Jefferson Starship, J. Geils Band, and Alice Cooper, all in Dolby Atmos. Atmos also mixes down to 5.1 on non- Atmos systems. They also have a box set of the Doobie Brothers, with all four of their quadraphonic albums.

Actually the real reason for quads demise can be boiled down to greed! Too many competing formats which greatly confused the public did not help either! And I disagree with your assessment of quad as gimmick. If done properly, it can give more depth and dynamics as well as other aspects to music reproduction. It allows the listener to hear more of what is in the recording at one given time. Instead of layered information and crunched into two channels, you can have multiple speakers doing the work that TWO normally do and as such can hear things in recordings that are otherwise buried. So it is not about realism as much as being able to hear MORE with a different effect at the same time. I love both two and multi listening and they truly are two totally different things! I do not agree with your assessment that it was just about companies wanting to sell more loudspeakers. Ok maybe cheap crap back then yes, But multi ch audio definitely has a purpose and a place when done correctly, To this da I HAVE TONES OF SACD DVD Able ray music in multo and it is some of the finest recordings I have ever heard still! It offers me a different dimension in music listening that allows me to be more in the recording studio and to hear nuances that were before lost in greater resolution.

Quad definitely started in the 70’s, and if I recall correctly there were 2 different and incompatible quad schemes or formats. It was a gimmick and no one likes a format war (remember Beta vs VHS? 🤦🏻♂️). And in a format war the better technology doesn’t necessarily win

Beta was a superior technology but VHS won the marketplace. For decades, TV stations used Betamax equipment for taping remote segments for their news programs.

@@jpatrickmoore5158 indeed I suggested that in a format war better tech doesn’t necessarily win. Sony had very different ideas than did JVC and it was the JVC model that proved far more successful - that was to align with studios and not just build a time shifting device.

Sony quadrophonic amp poor soon got rid of it and took a different direction.

Waaaaay wrong. None of main developers of quad; JVC, Sansui and Sony were known for their speakers. They sold far more receivers/TT/Tape Decks. EV was a speaker co, but not a major quad player. Anyone who actually heard quad liked what they heard unless it was a poor system or they had a closed mind. Quad didn’t last because they didn’t settle on one format and/or because some manufacturers didn’t include decoders for all the formats in their receivers

Hmm, SQ, SQ Matrix and four channel discrete. Too much gear, too little space.

I took it for a cool novelty or party trick but really? Who are you tryin to fool? When have you ever been to a live performance where the musicians were walking around the room? Imagine Kenny G doing that.🤣🤣🤣🤣 Now you could do some cool stuff in studio (DSOTM) etc. but only for effect, not realism.

Realism is so important, the amount of surround remixes I have heard where they are just waggling the faders 🤢

You are thinking in a very Limited perspective. There are many ways that one can create fantastic Holographic audio.. that blows ones mind. A better example, is a song like "Dream Weaver" which has very unique FM Synth sounds.. that have crazy panning and atmospheric effects. These types of effects could be even more amazing, with pans and sounds spread between all 4 speakers. Then you have New Age (no vocals) music from someone like David Arkenstone.. like the Album "A Wake In The Wind"... which is full of instruments, and is very much like a movie soundtrack. On one of the tracks, you can tell that you are sitting in some village... watching some belly dancers.. with cracking fire in the background, and indian-esc instrumentation. That experience, can only be more amplified in its effect of "Being There" , with more speakers. Just like a movies multi-tracks... can make you feel more like you are "There" (sadly, its often just not done well enough for most to really notice). Then you have special case music.. in which you can get even more clarity out of music, by putting some of the instruments on different speakers. Van Halen seems to do this often... putting most of the guitar sounds on one side.. and most of the drums on the other side (if memory serves correct... Im not going to fire things up at the moment, to make sure). With 4 speakers, you could create an even greater level of musical Detail. Ive personally noticed that when I used my amp on 3 channels.. that the left and right speakers became even more dynamic and detailed. This is because the center was taking on a certain amount of the work load... and it was reducing the work load on the left and right. This made for less distortions overall... and thus, much greater details + dynamics. Of course, I was using full sized speakers for every channel.. Not some garbage-tier, tiny driver'ed.. center channel speaker. While typical concerts, might have members walking around the stage... the actual music is always fixed from the speakers that it comes out of. But in most albums, you are not trying to replicate a Concert sound. You are getting a sort of faked 3D sonic soundstage, and 3d effects. Meaning, that there is no limitations to how you can experience the musical sounds and effects. If you want the guitars to pan from left to right.. or in the case of 4 speakers.. maybe you have dual guitarists playing at the same time... with one guitarists on the front speakers.. and the other on the rears. Heck... maybe you are in a virtual "Bill and Teds excellent adventure" concert.. where there are electric guitars playing on all sides of you... in some sort of epic Church like atmosphere. Steve Vai could probably make some really wild creations, with quad channel sound... Heck, theres a song by Bon Jovi, called "Homebound Train", where actual sounds from a steam train chugging.. are used. Something like that would sound even better, with surround sound. I can certainly tell you, that "The Polar Express" scene, where the train first comes to a stop at the house.. is flippin fantastic with a good surround sound system. Literally sounds like an actual train is rolling through your living room. The main problem, is the CD format, rather than using DVD/Bluray for High Definition Music. The next issue, is the fact that the studios are not going to re-release anything of value.. without compressing the original source material... to hell. Then there is the fact that virtually nobody is putting out new music worthy of listening to.. let alone, purchasing. And then there is ultra greed. The studios at once time... were charging like $20 for a CD. Its just way too much... especially for todays lousy quality. Back in the 70s to the 80s, you could buy a CD / Record.. and 8 out of 10 songs, were all bangin. These days, you are lucky if two songs are good... as the rest are total garbage that you never want to listen to.
