They may be quite a small operation, but I prefer to deal with 'local' suppliers when I can. If you bought an equivalent sub to the XLS200 from REL or similar it would be a lot more money.
Audyssey is the room EQ system fitted to most current Denon, Onkyo and other amplifiers. It is set up with a previded mic to match the speaker levels and balance the speaker's EQ. Unfortunately in my setup it applied a boost very low down that I couldn't really hear, but it caused my sub to be overdriven and it bottomed out a few times and damaged the cone.
