Positioning and Listening distance


As run-off from another thread ( Legacy speakers ), we ended up talking about speaker positioning, listening distance and minimizing room interaction. While we are all aware of the various formulas for speaker placement and listening position, none of these take into account the size or design of the speaker. As such, i've found that speakers with a lot of drivers or drivers that are spaced out quite a bit typically require a greater listening distance than a physically small speaker or speaker that uses just a few drivers. On top of this, the greater listening distance also tends to highlight problems that may be present in the speaker / room interface. While we can theorize on why this might be so, i was wondering if anybody else has run into this situation and what their experience / results were. Any / All comments appreciated and welcome. Sean

I too am a small room,near field listener (how does 9'8"x13',8'ceiling sound?)I really had to do some speaker auditioning before I found one that capably worked.I was also not willing to totally limit myself with one that wouldn't work in a more "normal" size once I finally get myself a more fitting location.After living with ML Aerius i's(I had Maggie IIIA's in previous house and couldn't give up the big spkr.sound right away),I auditioned Aerial 7B's and 6's (both of which were very engaging and musical, but far too ripe for such a small space... also lacked that top end air I was used to with the ML's).I tried both the Joseph Audios (RM22 and 25si's)but neither liked me sitting too near-field(I agree with the "multi-driver theory" of needing X distance, previously discussed, before they "Gel").Tried some beautiful Pro-Ac's which were very promising but ultimately ended up with Audio Physics (Tempo III's),a speaker wholly capable/actually designed for near-field listening.After A LOT of experimentig...both through listening and through the Stereophile test CD #2 (tracks 16,17,notably) w/ my RS SPL meter and measuring tape,note pad and graph paper, I finally found "my spot".I ended up with spkrs. just over 5' apart (that's center to center) and 3'from front wall,listening seat just a little more (about 5'8" or so)and just a bit over 3'from back wall.RPG diffusors on all 4 walls work well for me.Patience works.
Let me fix the confusing last few sentences above. When I say listening seat just a little more, I mean From the Speakers [in an almost equilateral triangle].I use the RPG's in the center behind the spkrs.(just one 2'x2'piece),then 2 per side {vertically stacked} at 1st reflection point, and finally 4 behind me,making a 4'x4'square.Outstanding imaging,commendable depth(especially in triode mode w/ my VTL monos),wiide stage, total disappearing act... yada yada .Ya gotta love this stuff... Kind regards,
I can truly feel the difficulty in getting the right speaker for a small room. My listening room is 12X13 with 15 foot cathedral ceilings. I have treated the wall behind the speakers and the short wall behind where I sit. Before treatment this room had a tremendous slap echo that was unbearable. I sit about six feet from the speakers. I have not heard the Audio Physics line of speakers and wonder what other speakers perform well in a nearfiled set up like mine...
Take a listen to the Audio Physics, the Pro-Acs,and whatever your closest audio stores display.... work your way "outward" from there? Good luck,happy hunting.
Hiflyer,

How did you treat the wall behind your speakers? Sounds like we have similar issues.

By the way, you might consider auditioning a BBC speaker like the Spendor or Harbeths. They were designed for nearfield listening, and they are very good in the vocal range. I own Harbeths, so I'm biased. But I love accoustical music and female vocalists. And, both the Harbeths and Spendors are very "sexy" in the nearfield with this type of music.

That said, I do need to tame my back and side walls.
