Home Speaker Asylum

General speaker questions for audio and home theater.

RE: AR2Xa speakers

They were designed before imaging was a big factor in speaker design. There is no way to get the 3 drivers in a sort of vertical line, best for imaging. If used horizontal the mids and tweeters line up but the woofer doesn't and it goes way up into the midrange, way above 1 kHz so horizontal changes imaging but only makes it different, not better. And then there's the diffraction affects of the raised edges on the front panel. The only way to really improve things is to redo the front panels so the drivers are in a vertical line, a big job.

The advice in checking the potentiometers used for driver levels is very good. This is a very common problem. Also the mid setting on the level controls on AR speakers are not flat, The mid set in the middle is lower level from the woofer and the tweeter is lower level than the mid driver. Flatest is actually with the controls set at max. AR was trying to compensate for the high frequency noise on many records of the day.
