What speaker for being close to rear wall?

Not exactly "right" sounding but very enjoyable stuff

Another option would be the Totem "on wall" (Tribe series) speakers.

I heard the Tribe V series with a Tribe Sub and they sounded amazing!

Ditto Vandersteen. Richard Vandersteen recommends that they be close to the back wall. If I get mine any further out from the back wall than 18" the bass starts to fall off, and they are very comfortable a foot away. The rear firing accoustic coupler needs the rear wall to augment the bass response.

For the past 5 years I have used PSB M2 Platinum monitors about 14 inches from the back wall and about 18 inches from a corner. All that seems to do is to enhance the bass, no standing waves. This speaker ports at the front which is better than a rear port when used close to the wall. Great speaker and not expensive either.
