I recently acquired a pair of ADS L1090's. And boy do they sound great! Extremely clear highs and mids, really tight bass. The silk dome and the midrange are just phenomenal. I have the version with the 6 1/2" Braun woofers, so they are the butyl rubber surrounds.
The metal grilles are classy too, although mine is falling off slightly.
I just need to get a new amp, because Im currently just using a lower quality surround amp. The speakers can easily go to 200 watts without a hint of distortion, but my amp sure cant.
