Power wise, 400 watts RMS is probably the correct range for this sub and integrated amp package. That's enough bass power to fill a small listening area of 400 - 500 sq ft. But for the package price and performance to expect, it's not Audiophile Grade gear. (Retail list: $699.99?)
You may have to experiment with the sub location, gain and crossover settings before getting the best sound possible. A good sub takes a few days of mixed play to break in properly too. When new, everything is tight and the deep lows will come later after a good 12 hours of use.
Good luck,
Swez
PS When shopping/spending on investment grade gear, take time to read reviews, go try and demo them and bring some of your own music too. This helps a lot to get a baseline on what the new items might sound like in our own listening room.
When we find what sounds best to our ears, then pull the trigger and buy from a reputable dealer. Took that approach to my first pair of Polk Audio 7a's monitors. They were over $400.00/pair retail in 1978, paid 1/2 that and they still sound smooth and clear after 30 years of use. (Never blew a woofer or tweeter in all those years... just a tweeter fuse was all)
