Today (10/03/2026) I purchased a pair of AR SAT 660 Speakers with the intent to repair or even upgrade them. Probably not a steal at $50 for the pair, but this is a hobby I enjoy.
Compared to most speakers this size and price range, I think they're pretty good. I think it's a more fair comparison to say they're better than the 1990s and 2000s era black box speakers made using thin material.
I knew the foam surrounds would deteriorate almost immediately, but I'm happy with the sound they produced for the 30 minutes they did, before I could hear the buzz from the surrounds breaking down.
I'm doing a little bit of a data dump in case anyone is interested in doing the same.
So, the box takes up 7" width, 7" depth, and 10.5" height. The black box without the decorative wood plates on the top and bottom is 7" wide, 5.5" deep, and 9.5" tall, made from 0.5" particle board, with the back wall set in 0.5" from flush with the back. Mine were filled with polyfill.
The hole for the connector on the back is 2" in diameter, the hole for the primary driver is 4" in diameter, and the hole for the tweeter is 2.5" in diameter with a 1.5" wide cutout for the connection tabs. That tab cutout gives another 0.375" to the diameter of the hole where it is cut out.
The tweeter has AR 1210096-0A 683TND stamped on the back, but no other indications. The woofer has AR 1210095-OB 783TNI stamped on the back, but again, no other indications. The crossover has ACOUSTIC RESEARCH PN 810136 marked on the bottom. Uses an unmarked iron core inductor, an unmarked air core inductor, a 2.2uf 50V capacitor, and an 8uf 10V capacitor, both about the same physical size.
I don't have the best meter at the moment but it measured 3.5 ohms on the woofer and 6.0 ohms on the tweeter.
