<!-- #thumb --> <p>Forced by circumstances to *point the loudspeakers in Music Room Two into the short 12 foot dimension of the room, as opposed to the longer dimension, is proving to be a challenge in terms of getting any kind of soundstage depth and focus. *It means the listening position is right up against the rear wall in order to allow the loudspeakers to be away from their rear wall. *A compromise to be sure.</p>
<p>Add to that the challenge of maintaining a properly sized center image, good tonal balance for all the instruments, and you have an interesting setup dilemma in this room – one I suspect many of you might have as well.</p>
<p>When you’re faced with such a situation most rooms are going to require some sort of room tuning; in my case, it means a set of three RPG diffusers centered along the wall directly behind the loudspeaker pair. *These diffusers set the image back beyond the physical wall and when the lights are dimmed, give a sense of depth that doesn’t match the space between the back of the loudspeakers and the rear wall – it becomes much greater – and sounds much more natural and like the IRS in Music Room One.</p>
<p>One does not have to use RPG brand of diffusers, I just happen to have this set left over from Music Room One. *However, this type of wall mounted tall wooden diffuser happens to be ideal and is much better than any round traps I have encountered for narrow small rooms.</p>
<p>Once these diffusers were put in place, I was able to pull the speakers a littler bit further into the room so that now they are a now about 52 inches from the front of the Thiel’s baffle to the rear wall, toed in about 4 inches, and separated about 8 feet from tweeter to tweeter.</p>
<p>The result is quite satisfying, although thin in the bass. *So, to*alleviate*the thinness I can move the speakers closer together or closer to the rear wall – but unfortunately that’s not in the cards if I want to maintain a proper soundstage. *What to do?</p>
<p>It’s late tonight and I’ll work on this again tomorrow.</p>
