Thanks for the feedback. Ideally, I would like to cross them over at 80hz (Audioholics said that is what B & W recommends for these speakers). However, the reviewer also switched to a 100hz crossover because he said it gave more fullness to the midrange. My previous speakers (orb audio mod4/mod2's) had to be crossed at 150hz, and the sub/sat blend was awful due to my large room with hardwood floors. The surround effects sounded so thin that it felt like two different systems were running. I always thought of localization as just hearing the sub's location, but it is also noticing a complete lack of body from the satellites, especially the rears. Anyway, since I have been using a 100hz crossover with these speakers, it has been like a whole new world. The sub and sats blend very well to my ears. Surround effects have body and impact. Anyway, since I really like the sound at 100hz and haven't noticed any distortion, I think I am going to stick with that crossover. I could try 80hz, but I would rather reap the benefits of added headroom since I like the sound as is. I may switch to 80hz if I put the system in a smaller room at some point.
