I used to have the GMX-A 2.1. I upgraded to the ultra 5.1's and like the surround sometimes for music, but noticed the subwoofer was not as good. It was much bigger, but it did not have the tight punch with the music that the 2.1 system had. Is there a similar subwoofer to the type that came with the gmx-a 2.1. I thinking of putting together a non powered setup that sounds like my old gmx-a 2.1. Price range would have to be similar to the ultra 5.1 or gmx-a 2.1 powered systems or less. Thanks.
