Actually my bad, I didn't know they were Elemental Designs, I've only heard them referred to as eD, but I don't know if their subs are any good. I know they do make good quality amps though.
The only reason I was even looking at them is that they have a "package maker" on their website. So, if you buy an amp (nine.1 in my case) you get 15% off your whole purchase if you buy a sub or comps or something. So, I would pay like $5 for a sub or $45 for a pair of comps cuz of the discount. I'd still like to hear from anyone with experience...
