Guest tgw Posted March 2, 2006 Report Share Posted March 2, 2006 Much has been written about the AR designed tweeters used in the 4x. Because of the 1200 Hz cross over any suitable replacement tweeters are hard to find, since most modern tweeters cross over at 2 or 3k Hz.I have one of these tweeters on the shelf that has an open coil. The other evening I was inspecting this tweeter and noticed that a rip had developed in the cone, which appears to be some form of rubber. My question is this. Are the cones on all of these tweeters on borrowed time? We of course can refoam a woofer, but I suspect that reconing these tweeters is not possible.Should we all begin searching for a suitable replacement if in fact all of the working tweeters in our AR-4x's may soon begin developing similar rips in the cone material?

charger3834 Posted March 3, 2006 Report Share Posted March 3, 2006 I agree with Vern 100%, just get another on ebay. Link to comment Share on other sites More sharing options...
Guest tgw Posted March 3, 2006 Report Share Posted March 3, 2006 Glad to hear that what I found was most likely a defective tweeter and not evidence of age deterioration. I did replace that tweeter with another I purchased on eBay.The fact that the cone material is not paper but rather some type of rubber raised my concern.

ninohernes Posted March 3, 2006 Report Share Posted March 3, 2006 The cone is paper, however some of the AR-4x tweeters are coated with a rubber-like sealer. Link to comment Share on other sites More sharing options...
