There's an AR Forum? Could you post the address, Joe?

You forgot:

1975, all AR tweeters blow
1976 all AR speaker electronics die
1977, all AR tweeters give up the ghost completely
1978, Steve sells AR3a's and rants: "I'm done with 'em!"

Sorry for the thread crap. They would still be around if their speakers actually lasted 10 years let alone 50.

Great sounding while they last though, if I had a "personal speaker maintenance attendant" around I'd still have a pair in my mastering room; most accurate and wonderful bass response I've ever heard.

Here's a link to a site with info about AR speakers: www.arsenal.net/speakers/ar/history/history2.htm

Scroll down to the info about the AR3 series; there's some interesting stuff from a design standpoint. The original AR3 had crossover points of 1000 and 7500 hz. 1000 hz is smack in the middle of midrange land where the ear is most sensitive - from a modern design standpoint, that's a no-no. Having a 12 woofer with a verrrrrrry heavy cone cross over that high would lead to poor off axis response. The midrange going out to 7500 hz would also be a stretch if it's cone/dome area were much bigger than 2" (and even there a 2" dome would be running into less than ideal dispersion at that a high a frequency).

A later revision has the midrange crossover point lowered to 550 hz (better for dispersion) and a new driver to go with the higher power handling needed at the lower crossover point. The midrange to tweeter crossover point was also lowered to 5000 hz - much better in the dispersion zone, but as Steve noted the drivers didn't tend ot have a long lifespan. The AR acoustic suspension line also accelerated the high horsepower race among amplifier manufacturers (and also fueled the development of transistorized amps capable of pumping out a lot of wattage/helped finish off any serious dvelopment in the world of vacuum tubes). Acoustic suspension speakers have come a long way since those early days of AR - the tradeoffs I've noted were ones AR had to make given the limits of speaker drivers of the day.

Also, they would still be around if they had not been sold to some chineese company that produces crap. When they went out, the hifi industry was turning around. Music listning was changing from hi fi, to plastic junk, and there just was no place for AR anymore.

Its funny you say this, because I have my Grandfathers pair of 1959 AR-2's and they still work perfectly. I Use them as monitors in my studio. I also have AR-3a's that I power with 200 watts per channel, and I have never had tweeter problems. What kills AR tweeters is distortion. If you have an amp that is not capable of driving a tough load, it will clip, killing the tweeters. Clean power=long life. There are still many happy AR users out there. As I said before, you need clean power, or they wont last. These are very precision pieces of equipment, and if they are abused by the user, well, shame on them.

Steve, you should have a pair in your mastering room. All you need is an amp that is capable of delivering clean power to a difficult load. Keep power between 100-200 watts per channel, and you will be fine.

If you really like the AR sound, check out the AR-9. The AR-9 is a floor standing speaker, with two 12 inch acoustic suspension woofers (same ones that are in the 3a), and I think, two midrange drivers, and two tweeters. These speakers are bi ampable, and are capable of handling over a thousand watts.

I'm just old enough to remember those AR-9's and AR-10pi's; you needed a lot of juice to get them up to room filling sound!

Very true. For the AR-9, I would say at least 150 watts!

indy mike · 08-09-2004, 06:20 AM

Minimum!

Joe Nino-Hernes · 08-09-2004, 06:22 AM

If I had a pair, I would probably be running them with 500 watts per channel. They can be biamped, but I am not a fan of biamping, mainly because its expensive!

indy mike · 08-09-2004, 06:35 AM

Yep, but you know the secret when you get a pair - Adcom!

Yup, I love my Adcom amps! Clean power, and very inexpensive!

Joe Nino-Hernes · 08-09-2004, 06:03 PM

Audiovox, the current owner of AR, plans to indroduce new products soon. They say that AR is going to be a high performance audiophile line of products. I really hope that they are real AR products, with the Acoustic Suspension design that made AR famous. I am afraid that audiovox is going to pump out crap with the AR name on it. It will be a disgrace to the name if they do so. I would rather have the AR name go away, then to have crap produced with the AR name on it. Its a disgrace to the quality of product that was produced in thier prime years.

Here are some of the products that made AR famous.
Picture one- A pair of AR-1 woofers with Janszen tweeters
Picture two- 1954 AR-1 ad
Picture three- AR-3
Picture four- AR-LST

Joe Nino-Hernes · 08-09-2004, 06:31 PM

Here are some AR Ads.

**Steve Hoffman** · 08-09-2004, 06:34 PM

You're making me nostalgic for those little bastards!

Boy, that's the cleanest control room I've ever seen.

Joe Nino-Hernes · 08-09-2004, 06:47 PM

We must not forget the legendary AR-9 either.

Casino · 08-09-2004, 08:07 PM

I'm gettin' nostalgic a bit too. Used to have a pair of AR-5's. Some of you will recall it was essentially the same as the 3a, but had a 10" woofer rather than 12".

Anyhoooo, I had 'em about 6 years, I guess. Were still workin' great when I sold 'em. Kinda miss that warm, solid bass, acoustic suspension sound sometimes.

soundboy · 08-09-2004, 08:53 PM

New Acoustic Research speakers taking pre-orders at J&R. Sorry, not acoustic suspension in design.
