AR3a Tweeters
Brilliant tweeters. I've finally completed the refurbishment of my AR 3a speakers with the OEM dome Tweeters. I'd previously used the re-foam kit from Simply Speakers on the Woofers. The midrange are original untouched. I also built a new set of crossovers - to get rid of the noisy switch mechanism and I replaced all the components. I'm extremely pleased with the result. Clear, well integrated sound and a joy to listen to. I've found the best placement is to put the speakers on their sides (as shown in the original brochures). I believe you get a more consistent sound with that alignment. I found the midrange tended to dominate the sound when the speakers are positioned upright. Great to have these 60's speakers singing again.

AR 90 speaker owner
I replaced two 35 years old original AR 90 tweeters with AR-12000840 4.75" replacement from Simply Speakers. Sounding is smoother in high end notes now which I missed them for very long times. However, little distortion is now more noticeable coming from the midrange drive. Because in AR90 4- way design, most of the sound is produced by the high-midrange tweeter instead of normally by the 8" midrange woofer. I will replace them soon and hope to restore its glory. Kim
