Speakers "Disappearing"


I have read a lot about speakers "disappearing" so that one can't tell from where the sound is emanating. But, what about all the stereo tunes where the recordiing engineer intentionally pans the music to come from one side or the other? Can the speakers be made to "disappear" in that situation? Or, is it just the nature of the particular recording?

I listened to speakers blasting 100 watts per channel, with a thin soundstage for 25 years. Then I stumbled onto a low cost single ended pentode stereo amp, vintage 1960’s, and viola- a soundstage appeared, with incredible detail and depth- using the same old cheapo Technics 3-way speakers w/15" woofers from my solid state setup. I still vividly remember exactly how it happened. The speakers in my system are 28 feet apart, and about 5-1/2 feet high off the floor, on corner shelves. I was sitting on a couch opposite the speakers, and listening to a Jimi Hendrix tape. Suddenly I heard what sounded like someone knocking on my window, to get my attention, about 3 feet to the left of the right side speaker. (speakers are against my front house wall). Turning down the volume, I looked outside and saw no one there. Then I realized, that was the DRUMS in the song, that’s how realistic they were. after the amp warmed up good, about 2 hours later, it completely floored me. voices were appearing in the middle of the room, sound was rising up into the air like a tornado effect. a pillar of sound between the speakers. yet the speakers themselves appeared to stand there silent. it was actually EERIE. like listening to a ghost band. what recording it was, didn’t matter, they all had this impressive soundstage. when the sound does pan side to side, it does so within the confines of the speaker placement, in the space between the speakers- not from the speaker itself. Listening to Led Zeppelin live, the drum set sounded like it was 20 feet away dead center out on my front deck. what you get is, 3 pillars of sound, one dead center, one center left, one center right. and also drum sound and audience noise behind that. my living room has a vaulted ceiling that goes from 8 feet high to 16 feet high, and the speakers are mounted on the low side 8" wall corners. this gives an arena, coliseum, or theater effect, and enlarges the sound stage even more. here’s the bottom line, you won’t get a huge soundstage with lots of bloom and depth, in a small room with the speakers close together. the soundstage grows with speaker placement, the farther apart the better, and the higher the speakers the better. after experiencing this, it totally changed my listening habits from high powered 100+ watt solid state amps, to low powered 10 watt tube stereo amps. and a single ended amp will image better than a push-pull amp. I’ve done dozens of back to back tests. the single ended still has that little better edge over the push-pull in detail and soundstage every time. an added benefit is, you get much more listening pleasure from low volume and save your ears. I was blasting my eardrums out for 25 years looking for good sound from high wattage, and found it with a mere 6 or 8 watts per channel. to date the 6BQ5 tube is unmatched for sound quality on a reasonable sane budget. someday I’d like to try a 300B or 2A3 amp but they aren’t the best for contemporary or classis rock music. the 6BQ5 does everything good, for a very low cost. it was basically the pinnacle of tube development before the music industry went to solid state around 1970. all the Beatles catalog was recorded using 6BQ5 equipment. it is a very sensitive, detailed tube with a lot of detail. my amp seems to take a long time to warm up, but once it does, it’s incredible. simply marvelous, considering it was dirt cheap. the key is, maintenance. all the caps, pots, resistors, tubes, coils, transformers in the set have to be checked, and up to spec. one tiny cap in the system that’s bad, will throw it off. the output tubes have to be changed every 6 months to a year or so. and the rectifier tube kept fresh as well. the preamp tubes 12AX7 seem to last longer.  Let me add this- once you hear music played in this manner, you'll never listen to music the same again. if it doesn't have that soundstage, other systems will pale in comparison and will sound like a car radio with a single speaker in the dash.  try as you might to describe it to someone, they'll think you're nuts and imagining things- until they hear it for themselves.  I demonstrated my system for my brother, and when he got up to use the bathroom, he was looking around up at the ceiling in the hallway, thinking I had flush mount speakers hidden there to enhance the sound- because it sounded the music was coming from there.  our house cat was laying on top of the couch looking straight up between the speakers for the source of the sound, it even faked the cat out.  so this is for real, not imagined.  and it's the holy grail that been lost, with today's Chinese-made crap surround sound systems, with their tiny 7 speakers for hooked to the TV.  they're a joke.  no contest. 
spread the speakers apart, you get a bigger soundstage between.  I did that experiment outside with more power and big speakers, on a 1/2 acre lawn.     the soundstage is precise and holographic between the speakers, and not as effective to the sides of the speakers.   stereo was originally designed with the listener seated between the speakers, and the speakers in the corners of the room.  anything other than that is a compromise, not following the original design of the recordings and stereo playback equipment.  if the speakers are placed right next to each other, it's usually because the listening room is on the small side, or the enthusiast is cramped for available space.  the ultimate listening room is a big 30' x 30' empty room with a vaulted ceiling rising towards the listeners' side, just like in a concert hall. that's why they build the auditoriums that way in the first place, not only for view, but for acoustics.

If I am aware of music coming out of a box, I feel like I have a system that is a failure. Ironic that Michael Green posted. I purchased a pair of his rev60(?) speakers years ago. I thought it crazy in the manual he suggested bringing the speakers half way out into the room and so far apart. But each time I moved the speaker out further and further to that location the magic got better and better. This was the single biggest audio epiphany for me--ever! Thanks Michael.



Michael hit the nail....I listened to wailing speakers and 100 WPC + from 1975 when I was 13 years old, until around 2001. then I got a beat up single ended pentode stereo amp for $10 on a lark, fixed it, and WOW- what a reality check. my high powered solid state amps have all been sold, or sit gathering dust, including my Pioneer SX-1250. you only need 10 watts per channel, if that. I’d still fire up a big solid state rig outside if I was having a huge outdoor party. but for precise listening and holography, the single ended tube amp is the tool that opens up great listening experiences. then you don’t just listen to the music, you feel, see, and WATCH the music, like watching a movie- the way the sound pops out of thin air, from all these different places, left-right-middle, and high, and low. also close, and far, and in the middle distance. all over the place. all the while the speakers sit there like they are off. if sounds like a ghost band is sitting in your living room.

BTW, I feel the same way about employment.  if I have to be hired by someone else or another company, I've already failed.  I have to be self-reliant.

my speakers don't physically disappear, they are up too high on a shelf, and are too big and heavy.  today's thieves prefer light, modern, high tech stuff to steal, preferably the otherwise worthless, useless stuff made in China.  hahaha.  having said that, my speakers are jammed into the upper corners of my listening room, not angled inwards and right against the wall and ceiling.  and they sound great and stereo image like a mutha.  every time one of my friends comes over, and angles them inward, they soundstage deflates dramatically.  less bloom and stability.  and that's all I have to say about that...(smirk...)
I've found that any and all speakers will image, and create a soundstage, from the most expensive high end you can afford, to the cheapest junk taken out of an old 1950's radio.   what will be lacking is the frequency range response, the better speakers will go higher and lower in frequency, than the cheap ones.  as far as the imaging and disappearing act, it still occurs if the amp has that capability.

all excellent responses and information- YES- the real soundstage while recording or live is much larger than our living rooms, that's why moving speakers APART further, dramatically increases the effect.  my speakers are 28' apart and if I could put them 40 feet apart, I would.  we did tests at my relative's house out in his back yard, with a high-powered solid state rig.  first off, I replaced the speaker wire with the largest diameter I could find, bougth a big spool of it at Radio Shack.  cut it in half, and put half that spool on each speaker side- for maximum length.  then we put the speakers at their furthest distance that wire would allow.  WOW.  the biggest soundstage from a home stereo I ever heard and saw in my life.  it was like a concert.  amazing, and impressive.

#2, yes get rid of anything between the speakers- but I'll take that one step further, simply RAISE the speakers up over everything, using wall shelves specially built to the footprint of your speakers, in each corner of the listening room. presto- nothing between speakers anymore, other than maybe pictures flat against the wall, or a clock.  again- dramatic improvement in soundstage, in this case- DEPTH is increased to a high degree.  it makes drums on a rock band recording sound like they are set up 15 feet away outside your house.
