I have a pair of AR 17s and I need both woofers. Finding P/N 200001-1 is near impossible! I found one AR 17 woofer on E-bay but it's got a poly (are they any good?) cone and mine did not. I'd like to get the genuine speakers, any one know of a source? I could use a recommendation for an AR 8" speaker that would be a good substitute if all else fails. There are a lot of 8" AR woofers on E-bay to choose from. Thanks in advance!
