Another American-Made Brand
I'm a huge fan of B&W (I have DSM603 s3s and an LCR600 across the front), but I haven't been hugely impressed by their subs, at least the ones in my price range (not very much). In fact, when I go to the store where I got my B&Ws and ask about subs, they almost always steer me to their Klipsch subs. Not sure why. The Klipsch sound okay, but don't do much for me.
So, lately, I've noticed that Audioholics is paying a lot of attention to Elemental Designs (did I get that right), so this morning, I went to the ED website, and, apart from the obvious Viagra jokes, I was pretty impressed by what I saw there. They're a lot like SVS, but rather than Ohio, they're based in Iowa. Like SVS, they do all their design and manufacturing in the states (if that matters to you).
On paper, at least, they have a number of subs in the $300 to $400 range that appear to be pretty similar to the low end SVS subs, but, they seem about $50 to $75 cheaper AND it looks like they offer free shipping.
Granted, everyone loves SVS, and I have my eye one one, but this deal on Elemental Designs looks pretty good. You may want to give them a look.
