I have a pair of M40's and QS4's in boston cherry for sale. These speakers are in great condition and have an upgraded crossover with soniccaps. THe speakers are in excellent condition and would rate an 8/10 due to slight use. One of the qs'4 has a blown tweeter and I called axiom for a replacement that cost about $30 but I never got to doing it. These speakers have been sitting in my closet since September after My wife wanted to rearrange the living room and never got back to using them. And as of now I have no use for them. I am asking $350 for the set.
