After spending a few hours with these, so far I'm happy with their performance.
They seem to do a very good job of keeping up with the Maggies. I've yet to detect any muddying of the sound.
I have them fed through individual sub connectors attached to the L/R pre-out connection. I'm using "Y" connectors at each sub to connect to the L and R subs line level ins.
With them crossed slightly above their minimum setting of 40 hz and the phase @ "0", they seem to be very smooth performers.
Their extension is noticeable and quite articulate.
I wasn't completely sold on the idea of adding any dynamic speaker to the mix.
They do seem to compliment the Maggies presentation though, especially at lower listening levels. I'll update as time passes. Thanks' for reading. I hope this helps others with similar thoughts. CD
