I have 2 friends who have recenty purchased the new B&W 802's and if you look carefully at the market its hard to find a product that will give you the quality bass,cabinet you asked for with a diamond HF unit. A very highly regarded speaker to consider would be the Grand Veena, Sonus Faber Cremona M, one of the Focal towers with the berylium tweeter. You could consider the new focal diablo syand mount which goes surprisingly low but really needs to be mated with quality electronics.
Tall Tower Speakers for $10-14k
Looking for full-range tower speakers at least 50" tall. Would be great if they have integrated subs to help with the lows. They also need to look really nice (like Canton Reference 1.2 look). Max I am willing to spend is $14k delivered in NYC. Please list any suggestions here. Thanks!
