I have a set of sansui sp-2500 that I moved on to basement storage, but am thinking about dragging them back out. Their strength is a nice cabinet and actually sound pretty good in mids and tweets..but lack the "infamous" bass. I remember when I recapped them how impressed I was at the quality of the woofers but was equally disappointed that such a nice woofer was so lacking in deep bass. I remember reading on a thread (can't locate it now) that the problem in the sp-2500 and 3500's was ill designed crossovers and after a minor tweek in the crossovers much deeper bass was being sent to the woofs and the problem was resolved. I have read that crossovers impact mids and tweets but have no bearing on the woofer. So is it possible for a crossover mod to impact bass?
