What speaker for being close to rear wall?

Linn speakers are--or at least used to be--designed for near wall use.

At least some of Rega's speakers can apparently be used close to the wall.

My understanding is that wall creates a boost in bass frequencies, which is probably why speakers like the original Linn Kan had amazing bass for the size. Thus, the overall design of the speaker has to take this boost into account.

All Klipsch classics

Anthony Gallo Stradas are designed to be within a foot of the wall. I use the A'divas in my office as they are 6" off the wall, and everything else sounded too boomy.

Gradient Revolutions

Guru speakers were the talk of the show in NY a few years ago.
Made to be against the wall. Incredible bass!
