OK, thanks a lot JKent! genek: 😆

Hello, I've bought some time ago some AR-11 speakers, and the previous owner had them customized with some metallic grilles (picture attached to my message). My question is : can it affect the sound quality? I tinkered the grilles to be sure that there is no contact between the midranges and the metallic grilles ; but still, would it be better to buy some classic style Acoustic Research grilles? Thanks a lot.

Thank you very much to all of you!

Thank you for your advice, genek! My living room is not so big, 185 square feet.

OK, thanks a lot, JKent! 🙂

Thank you newandold No, I'm not planning on to do so, I was just wondering if it's enough because I've read that all the Acoustic Research 12" woofers speakers are power hungry.

Hello everyone, My NAD C 326 BEE has: 50W x 2 Continuous Power into 4 Ohms and 8 Ohms ; 100W, 150W, 200W IHF Dynamic power into 8, 4 and 2 Ohms, respectively Do you think it's enough to drive my Acoustic Research AR-11? Thanks a lot. Arthur

Thanks a lot, Aadams!

Thanks a lot for your answers! Here's the back :

Hello, does anybody knows which model of Acoustic Research tweeter it is on the picture? Does it fit an AR-11? Thanks a lot.

OK, thanks a lot, AR55 and JKent!

Hello, Does anyone know if the AR-3A front-wired configuration midrange is the same as the AR-11 midrange? I just put an AR-3A front-wired midrange inside my AR-11, it seems to work quite fine, but I was wondering if it is really equivalent. Thanks. Arthur

Hi everyone, I've both the AR-3a and the AR-11 speakers, and there is indeed a difference in the bass. The AR-3a bass is deeper, smoother and go lower, whereas the AR-11 bass is lighter and more subtle I would say, as you can hear a more discernable difference between bass notes. Listening to the AR-11, I discovered some new aspects of the bass notes of my favorite records, that there a difference between "high bass notes" and "low bass notes". It's like if the bass is singing. Sometimes I change my speakers from AR-3a to AR-11 (and vice versa), depending if I prefer to hear a deep and smooth bass or a "singing" bass.

OK, thanks a lot Aadams!!

And here are the photos of the ar-11 woofer

Thanks a lot for your answers, here are the pics of my ar-3a woofer. It is only written Dec 1 - 1972 on it.

Hi everyone, one my ar11 woofers is damaged, do you think I can connect an ar 3a woofer instead inside my ar 11 cabinet? (I have an ar 3a woofer in stock) Thanks a lot. Arthur

Ok, thanks a lot ra.ra! I'm gonna check the restoration guide.

Ok, thanks a lot Aadams, I have already read on this forum that the bass are maybe smoother and a little bit deeper on ar-3a than on ar-11, that could explain the difference to my ears.

Thanks Aadams, the ar-3a are an early version I think, because the mid-range and twitters are front-wired, and the woofers are originals. My ar-11 are the Teledyne version. Do you think it isn't worth trying? I will supply some photos. Thank you again!

Hi everyone, I was wondering if it is a good idea to replace the ar-11 woofers by ar-3a woofers inside the ar-11 cabinets? It seems to me that the ar-3a woofers are a little bit more powerful than the ar-11 ones, the bass are deeper, I noticed when handling them that they are also heavier. Thanks a lot. Arthur
