I am looking at adding a sub to my system. At the mo my front speakers do all the bass. http://www.aadsound.com/Products%20P...ct%20page.html Anyway the specs say these speakers go to 30Hz but I am pretty sure the dont go that low (maybe at -10dB). If I add a sub will there be a noticable difference in music and HT. I have the HK 220 avr, and in music stereo mode you send all the bass info to the front speakers and the bass. Hence getting a doulble up of bass. You can turn the bass in the 2 front speakers down to make up for this I suppose. If using this config and the bass coming out of the sub is also coming out of the front speakers is it a 3dB gain or 10dB gain?? Would I find this annoying or should I be able to get a go blending of sub with the front speakers? One last question. Is a sub good for music or not noticeablly better than decent front speakers.
