Shedding a little light....
Elan is part of a very large company called Nortek.
See all of the Nortek brands here:

Particularly under the Linear LLC section. You'll see some heavy hitters in that section!
Does this mean that the Elan subwoofer is "good"? No. It's an alright product. Elan theater stuff has gotten some pretty decent reviews. They pride themselves on their in-ceiling speakers (which are pretty decent). It's not like you're secretly getting a cheaper version of one of the Sunfire (also owned by Nortek) subs.
The rep in my territory has been pusching the Elan stuff at me for years. It's really nice, really pretty whole house audio product that's also added some really cool home automation expansion capabilities to it. Expanding into HT speakers was a natural progression when the market was booming. We'll see where they ultimately go with it. As a custom theatre company, I'm not too thrilled with their speakers. It's more geared towards companys who already carry Elan electronics who just want to sell the "brand" as an easy transition sale on a project. "Oh, Elan Amp? Elan Sub makes sense too then." sort of thing. I couldn't imagine a dealer picking up Elan JUST for the speaker side of it. Make sense?
I think that if you're in the market for a great deal on a sub, hold out until you find something "great" that fits your price point.
As a dealer, I'm always buying things in bulk to sell at decent price breaks to clients & unloading what I don't need either on e-bay or places like here for a steep discount (if I don't have to install it I cut the price wayyy down).....

Yes, a shamelss plug, but a good deal none the less! I'm not the only dealer who does stuff like this. Wait until you find the right piece, not just the right price!
