I think your claims are without basis. I know what you're talking about, namely bass modes excited due to the subwoofer. However, speakers can sound GREAT in a store and like garbage in your house if you don't have enough treatment in place, or if you're trying to drive Polk LSi speakers with an awesome
Kenwood Receiver. Neither one is more important to listen to in your home.
And regarding the original topic of this thread, I don't think you should worry about SVS and Hsu Mike, as they don't distribute to the Philippines.
