Iv'e had my Accusound's for about 6 months now, and i love them. I pushing them with a Yamaha RX-V430 This only puts out 75w per channel rms, and the speakers are 150 watts rms. From what iv'e just read under powering speakers can cause harshness when you crank them up. I also have a really annoying peak in room response @ 51Hz, it makes it sound really bloaty and horrible. My Room Dimensions are : L=5M W=3.5M H=2.5M. Is it worth getting a new amp? Or do you think its room acoustics? I'm only 13 so i don't have big $'s to spend on equipment.
