I purchased a pair of AR-5s off Craiglist. Both speakers had Radio Shack replacement woofers in them. My question is this: does it make a difference if I purchase set of 10-inchers off E-bay from the era, or, alternatively, should I just go ahead and spend the $ on replacement ones off Vintage AR Parts. There's a set of AR-5 woofers on e-bay right now for $130; Vintage AR will sell new a new replacement pair for another $10. Are there any opinions about which of these woofer replacements would be better. Or, alternately, I suppose I could keep the radiocshack polycone ones.... Any suggestions would be appreciated. Thanks
