Listening position/speaker position


I had a friend visit this weekend for some extended listening. I generally trust some of his suggestions, and his hearing may be better than mine, but I am 61 and don't have any hearing "issues." Also, in the interest of full disclosure, my friend and I are competitive with each other so there is always the possibility that he is busting on me.

 

I am very happy with my setup and my sound----the room is quiet, the system is quiet and I have low distortion, plenty of punch and volume, without sacrificing any detail. I have Revel 228be speakers, a McIntosh MC312 amp, C53 preamp, Pass XP-17 phono stage, Technics SL1200G TT run with an AT-art9xi MCC.

 

Anyway, my listening room is approximately 26' x 15' with less than 8-foot ceilings, plaster walls, wall to wall carpeting, lots of cushy furniture, and it's perfectly rectangular. I have my Revel 228's positioned on the narrow end of the room, a couple feet from the side wall and about 2-1/2 feet from the back wall. The listening position is about 10 feet from the speakers, or just shy of the midpoint of the room. My critical friend was suggesting that by having the speakers at one end of the room, I am asking them to "fill" a 26-foot room, despite the listening position being near midpoint depth. He suggested that I put the speakers in the middle of the room and move the listening position against the wall, so that the speakers are only tasked with filling half of the room. He also implied that I was under-powered with the MC312 which doesn't sound valid..

 

Obviously, the only way to know if I would get sound improvement would be to swap sides in the room, but his suggestion sounded so odd that I thought some of you with more experience might have an opinion.

@vthokie83   I suggest you try the speaker front baffles about 6.5 feet from the front wall. If you can add some diffusion on that front  wall it will deepen and expand the soundstage. Do not put any absorption on the wall behind the speakers, Open baffle need to breath from what I have researched. But you can just pull them out with a "bare" front wall to test it. If I am right your soundstage will be enormous. Now how about the Aric Audio ML XL report?

Fred,

Sorry that will take a bit, I've got to completely redo my audio rack because the Motherlode XL is a "two box" configuration to isolate the power source from the signal components......connected by an umbilical. I can tell you that it is one of the most beautiful pieces of tube gear I have ever laid eyes on.....mine is finished in maple.

Just another suggestion is that you might want to try the Wilson Audio set up guide.  Just relying on mathmatical calculations may not be the best solution since all your furnishings would affect the sound.  Just trust your ears but your friends advise in my opinion is bogus.

@willyht I haven't read through all the comments in this thread.  So, this is based on personal experience with similar components and, of course, my opinion.

My listening room (i.e.  living room) is almost identical to yours, both size and shape-wise.  However, acoustical properties are different.  I've got the wall-to-wall carpeting and cushy furniture.  However, my ceiling is 9' high and it and the walls are solid wood (i.e.  log cabin).  I have a pair of Revel F206 powered by a MAC integrated.  The speakers are approximately 22" from the wall behind them and separated from each other by approximately 6'.  More would be better.  However, I am forced to deal with living space and aesthetic concerns; not to mention SWMBO (She Who Mus Be Obeyed).  Listening position is approximately 8' from the speakers with about 2' of space behind that.  Again, a little more would be better in this regard, if not for the aforementioned limitations.

If memory serves correctly, the 228be have Beryllium tweeters.  While I haven't done much seat-time with Beryllium tweeters, my sense is that having a healthy amount of empty space behind the listening position with these would be an advantage, especially with regard to listening fatigue, much in the same way as it would be with AMT tweeters.  I've found that pointing my F206 straight out at the listening position is better than toeing them in and encourage you to experiment with this, if you haven't already.  Off-axis performance with the F206 is about the best I've ever heard.  My guess is your 228be probably excel in this regard, as well.

While you can, of course, go through the bother & effort of what your friend has suggested for your equipment, my suspicion is that this will result in time & effort wasted.  If you do experiment, however, please let us know what comes of it.
