One tweeter for the AR-3a and AR-LST with the front wired configuration. We initially have two available. We are now offering a repair service for these. These are two we have rebuilt with a new voice coil, fabric dome that snaps back should you inadvertently bump it, new suspensions internal and external, new long leads for installation and a replacement mounting flange. These early production tweeters had rather soft mounting flanges which often distorted when installed. We have added new stiff flanges to the rear. These are then tested with test equipment and a music source.
