Subs and SF Amatis

I have not heard the amati's with subs in particular but I know they are full range which are the easiest and least intrusive to match with a subwoofer. The lower the crossover point the better. I'm guessing the amati would crossover somewhere in the 20's which is extremely low.

By a fair margin the sub will sound it's best in a corner. This is because you can position it so that it excites the corner walls and uses them as large passive bass radiators.

disclaimer: I am a REL dealer.

Last week I heard the Amati's on a Pass Labs X0.2/X600 setup with and without a REL Studio subwoofer. The Amati's are full range, but adding in the sub gives you a sense of the venue.

I heard a striking set of a/b comparisons. The demonstrator would say "now we are in the church hall", unplug the sub, and say "and now we're in this room". He was dead on right. You still heard the performance, you just didn't perceive the room.
