Hi, I have HT equipment that is i suppose a few years old. My speakers are Bose Acoustimass 5 Series II and acoustimass 7 for the rear. My reciever is kind of old, it is a Denon AVC 2000. Anyways, from the begining I haven't gotten as much bass as I want out of it.I really like bass, for music, and movies. But i can't seem to get much out of the speakers. They are crystal clear in terms of vocals. Is it my reciever, or my speakers, or both? Also, I noticed that the bass modules on my speakers branch out to my cube speakers. And then bass modules connect to speaker sets A and B on the reciever. there is no pre out. what does this mean? Arg. so confused. I was wondering what should I do? I want a new reciever. I was looking at a Harmon Kardon AVR 120. Can someone give me some adivce on which way to go?
