Re: Teledyne Acoustic Research AR9

Yep I was 18 yrs old when I first saw the AR9's at a Pacific Stereo here in Houston, Tx. I was a senior in high school and wanted to paint my '65 pontiac and buy a stereo and speakers with 1 loan. So my dad cosigned a loan for $2000, $1000 for the paint job and the rest for stereo. I ended up buying a Marantz 2252B receiver and 4 AR14's. Didn't have enough for the AR9's which were $750 each, 1979. Still today the Marantz and all 4 speakers work as good as the day I bought them. Well the Marantz has a little noise when I move the volume knob, but quits when I stop, and still sounds great. Of course now I own Mcintosh amps and 2 K-horns. I have over 3000 albums and play records on both systems, you just can't beat the sound of vinyl.

Re: Teledyne Acoustic Research AR9

I have a pair of AR-9s and 4 NHT VT-2s. I bi-amp my Onkyo txnr-818 and push my AR-9's w/ my old (1981) JVC M3030 (150w). The 818 struggles to push all those speakers so I pulled out my old JVC-solved my problem. I do not use my subwoofer unless watching movies-no need for it when listening to music.

Looking for advice on best power amps to purchase to bi amp with my AR9 speakers

Re: Teledyne Acoustic Research AR9

Hi there. I own 3 pairs of AR9's but I am using only one pair because my room is to small for it. The more power you have the better this speakers will sound, I power my 9's with a Soundcraftsmen A5002 power amp in BY-WIRE connection, I had it in BY-AMP connection before but the Soundcraftsmen MA5002 needs some repair and I pulled it out of service. The best way to connect them is in BY-AMP mode but you will need two power amps, the second best way is BY-WIRE connection in this case uses only one amp but you will need to remove the jumper in the back of your speaker's binding-post input. I recommend a 4 channel stereo amp just like my MA5002 or A5002 they put out 380w/channel at 4 ohms you will need this much power if not more. Now the most important is make sure your amp must be stable for 2 ohms!!! Otherwise you will fry your amp for sure!!! Also when you do this kind of connections make sure you remove the jumpers on your speakers all of them and the polarity must be correct from both amp or it will short it out, means red/+ goes to red/+ and black/- to black/- !!! High power CARVER, McIntosh will be great. Good luck.

Possibly the most accurate loudspeaker ever made

Too bad Teledyne AR went out of business. In my opinion, no speaker before or since matched the old Teledyne Acoustic Research AR-9 for clarity,neutrality,accuracy and superb imaging. I know there are people out there who
would be of a different opinon but in my opinion they are mistaken if they don't acknowledge how truly superior these loudspeakers were.

Re: Possibly the most accurate loudspeaker ever made

I worked in the industry for many, many years before switching to IT, including years at Pacific Stereo where I got my AR9's second-hand as trade-ins. I've listened to a lot of speakers for over half a century of being an audiophile and the AR9's are still my favorite. If they weren't I would've replaced them.

Mine are part of a home theater system which is also used for music. The other speakers are Polk. Everything is driven with Carver equipment...TFM-45, TFM-35, TFM-25 bridged, and a pair of TFM-15's. I've tried other amps and I'm content with the Carvers.

My TFM-45 has a couple milivolts of buzz in the outputs and I happily discovered this site to get a schematic. I'll upload any old servicing diagrams I can find as compensation for the sorely needed service literature. Heck, I'd gladly pay.
