Edmonton has two great dealers which doesn't help you much I guess (FX Audio and Adrenaline Audio). I have a Diamond Audio TDX 12 and a Diamond Audio MKII 10 inch (basically the D6 sub). The TDX is by far the best sub I have ever owned or heard.

I also had D5 6inch components that were nice, but a bit harsh. The Hex components I am running now are very smooth as long as you have 100-150 RMS to run them.

I also have a D7 2 channel amp (old Esoteric high end SQ) and a D5 (now the D6) 2 channel coming. I am going to run them both on the 6.5 Hex's and keep the best one and sell the other. If I can't hear the difference I will sell the expensive one (the D7152).
