What qualifies as a stand mounted speaker? I noticed someone mentioning the Harbeth 40.2 XD. It is a box on a stand, but, it is a big box on a stand and is meant to be treated as a big speaker--placed in big room, well away from the walls.
My local dealer, Deja Vu Audio in Northern Virginia makes custom speakers, including a stand mounted speaker that looks very much like a 40.2 Harbeth on steroids--similar proportions. The drivers include an 18" woofer and Western Electric horn and compression drivers that now cost well north of $20k just for the drivers, and a Fostex tweeter. The crossover includes some scary expensive Audio Note capacitors. This is one of the better stand mounted speakers I've heard, that is, if it qualifies.
