I bought an RCA "stereo in a box" out of a flier I received in the mail. Oh the horror when I received this "stereo system" They contain in their QUARTER INCH thick cabinets one 6 inch "woofer" a 3 inch "mid" and a one inch "tweeter" The backs of the cabinets are eighth inch fibre board that is held in place by -get this- nails that were driven parallel to the panel so when you turn the volume up you can see this back panel pulsating to the disgusting cacophony that is emenating from the soon to be blown speakers.
That was 4 years ago and now I own a wonderful system with 30's for mains a C-7 center,ss-1 rears,KSB 2.1 rear effects/surround music, and a KSW 12 sub.Driven by a Denon AVR 4800 and with a pristine Parasound HCA 1500a pushing power to the 30's.
THANK YOU KLIPSCH!
