Best near wall high end speaker

Actually the VANDERSTEEN Quatros are made to be that close to the rear wall plus it has tunable bass so you wouldn't have that reinforcement problem. I'm moving up to those as soon as I sell my Treos which also sound great close to a wall. They both port out the bottom.

Aerial Acoustics LR5's are designed for near-wall boundary placement. They require a sub, but are extremely accurate. A negative is their rather boxy/utilitarian design. A positive is that they can be found used at very attractive pricing.

Larson..another vote for. Heard a pair a model from top of range in Healdsburg ( so i may have also had some wine). Pretty stunning sound for boxes right on the wall.
More engaging than the Blades they had ten feet into the room.

PMC perhaps?
