Now I bought these about 3yrs. ago and got them for the incredible price of about $45/pr. I have owned other Sony speakers in the past and have always been completely satisfied. These have great low end and crystal clear highs- just check out the frequency specs.. The can handle plenty of power and can belt it out when driven hard. I'm driving these with a Boss CX1800 that delivers 110W/RMS/Ch. to them. They can handle the bass extremely well with the +18db bass boost switch kicked 'in' that you will not feel the need for a subwoofer at all. +18 is rather excessive and I don't run it that way, but with it 'on' these speakers handled it without any sign of break-up. Your regular bass EQ adjustments will provide enough bass gain if needed. I don't think one can go wrong buying these great speakers.
