No rear ports.
I just put a restored pair of AR2ax’s horizontal seated ear level in my office. They are only 11-1/4" deep (+ spkr wire), 13-3/4" high, 24" long
Compact acoustic suspension 3 way with two level controls, and a 10" woofer. That’s a lot of speaker, very smartly designed for true bookcase use.
Sound so good I just bought a second pair for my garage/shop system. They will also be horizontal on a shelf, standing ear level height facing the stand-up height island counter where I work on projects.
When horizontal, place them with the tweeters to the center. Then, just to prove that’s best, flip the tweeters out.
Using the level controls, you can adjust the mid to the bass and the tweeter to the mid, by ear or get a test cd and inexpensive sound pressure meter (with threaded hole for tripod mount. That’s what I do for my main system, these other setups, I just go by ear. Adjusting in the space is a terrific asset.
IF your friend is handy, this would yield a great pair. Local Pickup Only. You would need to live close, or make arrangement with a UPS pack and ship near seller. Seller merely drops unwrapped items at the UPS. That’s how I got my first pair.
I don’t see any restored ones on hifishark today, but they pop up frequently.
If your friend is interested, send me a private message, I know all about them.
