Help identify Acoustic Research Speakers

[kidadam]

Hey, wondering if someone can help me identify these speakers.

I thought they could be AR4-xa but the wood trim around the grill is different. Any ideas?

 

[swechsler]

The tweeter certainly looks like an AR. Is it an AR woofer?

The driver configuration and back plate/terminals/attenuation switch all look correct for 4xa, but I've never seen that cabinet. I'm sure some of the real AR experts will weigh in soon.

How do you know they are AR? I don't see any identifier in the pictures you posted.

I "think" they might be end of run AR-6's.

Look at the back plate...sure seems AR-ish. I guess some other company could have mimiced it, tho.

More shots of the AR-6.

AR6 seems to be a close match. I think they sound great, the stage is really impressive. I may pick up a Scott 222d to run them.

Seems like we have a winner! I have an older set of AR6's, with Zobel on the woofer. I think they are exceptionally good for their size and era. Low frequency performance is astounding for such a small box.

Thanks, everyone!

I was originally selling for a relative but after demoing I decided to build another stereo for the attic or maybe cottage.

@StimpyWan for the win!

I wasn't questioning the OP's initial post I just hadn't seen any AR's that looked like that.

 

[baco99]

AR6 for sure.

I have those too. They also have a different woofer than the later run which used the 'standard' 8" woofer. The older models with the inductor on the woofer circuit have a woofer where the magnets surround the voice coil for a longer throw. Those go as deep in the bass as the AR 10" woofer. The AR 6 in the first pics may be a European model. The cabinets were a bit different. The oldest AR 6's have variable pots. The newer ones with the standard woofer have toggle switches.
