Hi

For the best possible advice, I highly recommend you contact your local supplier or the Manufacturer....

Definitely the polk! It's way more powerful and Polk is a great speaker company. I just bought 5 speakers for a 5.1 setup and I'm actually about to order the polk sub you listed. It's a very nice, powerful sub. The company is also very respectable and they have a 5 year warranty on speakers and I think 3 years on powered subs.

Good luck! Hope you like whichever one you decide on!
