Recommendation: Wharfedale Powercube 12 or Yamaha YST-SW216

Hi

Does anybody have any experience with either of these subs?

Im gonna be pairing it with Orb satellite speakers, and the Orb people recommend around a 10 inch sub to blend in well

with their satellites (Im not too familiar with what blending means exactly)

Both Subs have the frequency range for the crossover settings ill probably end up using.

The Yamaha has pretty good reviews from what Ive seen, but the Wharfedale powercube 12 seems to predate reviews as

they seem to have been around since forever and are very common.

Any advice appreciated! plus seperate recommendations (under $500)

Thanks
