AR 2ax Tweeter choice: Opinions wanted

[-reverb-]

They buyer seemed pleased that a modern tweeter of high quality had replaced the older AR parts.

I would have liked to have kept them, but something had to go and I just wasn't attached to them as much as my other choices. In the final analysis, I probably lost money on the deal or maybe managed to slightly break even. I had the original cost of the cabs, 2 replacement woofers, 1 replacement mid, 2 new tweeters with inductors and I rebuilt the crossovers. Oh yeah, new grill cloth too.

Here's the entire rebuild thread if anyone is interested.

Hi all,

I am rebuilding a pair of AR 2ax's and have all original AR drivers except the tweeters. I don't really care about resale value I just want a good sounding set of speakers

When I go these, the originals AR's tweeters had been replaced with a pair of Realistic 40-1276 dome's. Not a bad tweeter for sure but the down-side is they do not fit well in the opening. Even with an adapter ring, the fit will still be problematic because of the screw pattern and their location.

While researching I found some have decided to use the HiVi Q1R from Parts Express as a replacement. RoyC did some work and determined that if you add a 0.05mH Inductor, it matched well to the original AR part.

Lastly, I could find a pair of correct AR tweets. As I understand it based on my production date (72-73), these would be the black dome versions. My concern here is age and how much the tweeter has drifted from it's original voice.

So my question is, which ones to use:

1) Realistic 40-1276's
2) HiVi Q1R's
3) Correct AR replacement Black Domes
4) Something else

Thanks for any opinions!

I have talked with Roy and he said the red phenolic domes are interchangeable without any crossover modifications.
While the domes themselves are much larger, they are direct drop-in fit regarding the flanges.
