Added some AR 2's

Got them locally. They've been sitting basically idle for the last 5 years, and one of them seemed to need a bit of power to wake up and come to life. But now they're both singing and sounding quite wonderful. Much better high end then I expected. Have them on top of Kliipsch Cornwalls, and driving them with a Fisher 500C.

Well of course the Cornwalls are more efficient, and larger, so they play louder, and are more dynamic. But the mids of the 2's are much better then I expected, and they have a wonderful, warm sound but not veiled or congested as I was expecting.  They've opened up nicely since I started listening several hours ago. After speaking with the seller tonight, I learned that he had never used the 2's since acquiring them years ago, and was told that they had sat idle for decades.

Someone did a very nice job on finishing that pine. Does the grill material have gold thread in it? I can't tell. I really like that grill material and had it on some 2a's I had. Very classy.

Yes the gold thread is in there. A little easier to see here

So I just bought a pair of Microacoustic microstatic tweeters to use with the 2's. Should I be disconnecting the tweeter connections on the speakers and just using the external tweeters, or do I use them in conjunction with the speaker mid/tweeters?IMG_6450.jpg

The MicroStatics are supertweeters, so use them WITH the AR tweets.

I posted instructions somewhere. Lemme see if I can find them.

Here they are (download below) Wire in parallel with the speakers. AR terminal 1 to MicroStatic terminal with dot. AR 2 to no dot.

Thanks. I actually found those last night after I posted, but decided to get some feedback from members here to see if anybody had done differently. One of my 2's mid/tweets are a little quieter then the other speaker , which is why I got these. And I thought I might use them like AR 1W's and just use the external tweeters. But I'll try both ways.

The AR-2 speaker’s frequency response is 42-14k +/-5db when new and crosses over at 2,000HZ. This means there will be cap from 2,000 to 3,500HZ. when the Micro-Statics come in at 3.5KHZ. That’s an awful lot of music not coming through and missing if those two 5 inchers are deficient to begin with.

I’ve seen others pull out those twin 5 inch speakers which only go up to 14,000HZ anyway and mount a wooden plate and install two other type of speakers in place.  A bit daunting but, do-able nonetheless.
With the newer AR-2a iteration, AR simply mounted an additional tweeter however, the AR-2’s may not have adequate space as is to do this with-out some reconstruction of the front baffle.

Regarding the “Micro-Statics”; they’re capable of handling large amounts of watts with-out complaining. I know, I've owned them since 1974 and have relied on them with-out a care of damage.

In any event they're almost a necessity for most any vintage AR speaker. Judicious volume setting is key to 'syncing' with host speaker.

Frank & Kent - how would you describe the nature and quality of the sound from these tweeters?

I've seen interior photos of the Microstatic, and the drivers look like inexpensive cone numbers. Are they up to the greatness of the AR-3a or LST?

Picked up a JansZen Electrostatic  Model 65 tweeter today for cheap. It's had some restoration work done.  It should come in around the same time as the the Microstats. Evidently that one is best used with the speaker tweeter disconnected. I'll report back.

Quality is very good. I believe the drivers are the same as those used in McIntosh speakers. And they're not all that audible. Above 7kHz they're just enhancing the very high frequencies, giving the speakers more "air" or sounding less "reserved" or whatever audiophool terminology applies. It's subtle.

Thanks for the info!

Well whatever was causing my one AR2 to be quieter then the other is now fixed. I had the speakers out of circulation for about 2 months, and decided to put them back in over the weekend, contemplating opening the bad one up and seeing if I could get it going. Upon hooking them up(with the Microstats) the speaker in question produced perfect sound, loud and clear, and now provides equal output to the other. I'm curious as to why this happened. I'm guessing it might be the caps reforming, as the speakers had been laying idle(according to the previous owner) for many years. I've also played around with the pot, and maybe some of the corrosives fixed themselves? Whatever it is, I'm glad it's operating as it should because they sound great, and the Microstats really do a nice job of bringing out the highs and adding sufficient amount of air to the presentation. I'm enjoying them more then my 2ax's at this point . 

Glad I didn't have to mess up the beautiful grille by opening it up. Hope it never comes to that.
