Hey guys this is my first post, and I'm new to the audio world. I bought an onkyo htr- 502 around 2 years ago, as well as some paradigm moniter 9's for the front. I had them for about 4 month's and just realised that the right speaker has much less bass responce then the left, tried switching the speaker wires and it didn't make a differance. Also noticed that through the port hole there is no air moving even at fairly high volumes as, but the other speaker does. Any help would be awsome.!!! thanks kevin
