You will be better off starting a new thread for your project. Remove your woofers and provide close up photos of the crossover circuitry. The minimum voltage is written on the side of the caps. Higher voltage caps are OK, lower voltage is not recommended. If you have early 10 Pis with Sprague Caps they are probably ok.

Before someone else does it for me I need to correct my error. Your setup as described is within the Roy Allison recommendation at around 26 degrees off axis, not 45 as I erroneously stated above. I would still toe-in the speakers.

Ok, I'll go first. AR's recommendation was to start with speakers 6ft apart and listen no closer than 3ft, which is the same as no greater than 45 degrees off axis. Roy Allison's general recommendation for all loudspeakers was to listen no greater than 30 degrees off axis. Your setup as described above is around 45 degrees off axis without toe in, which is a bit much for a 2ax. Of course ears vary but my subjective opinion is, because you are not using the rear wall, I would recommend try toeing them in 45 degrees to put them on axis in relation to the listening position.

Those look similar to the stands built by @xmas111 linked at the bottom of this thread about LST stands. The wood support posts are sandwiching tensioned steel rods that bind the top and bottom pedestals.

Instead of turning the tweeter up perhaps turn the mid range down. The graphs show the 2ax tweeter output and range is identical to the 3a and 5. It is deceptive and not intuitive, but the wide and uniform dispersion of the "lower output" tweeter is responsible for keeping the 2ax power response curve horizontal from 5k to 12K. Unlike a 2ax, a properly working 5 can exactly mimic a 3a above 50hz when positioned identically, with the added bonus that its 10" woofer will not excite room modes and muddy up the midrange in small spaces. I have never heard an early 2ax.

The charts below from the 1975 brochure say they will all sound very similar on axis. There is a practical range of setup and listening parameters within which all three systems can be made to sound nearly identical. If your listening preferences and system arrangement begin to favor the greater power response of the domed mids or the low bass of the 3a, you will hear an obvious difference that cannot be duplicated by the 2ax. But my real world subjective answer is, the 2ax can sound practically indistinguishable from a 3a or 5 when playing recordings of musical performances captured in a studio environment.

Welcome Stillhouse. Very nice early pair. Be sure to download and read the AR3a restoration guide,

There was a chart posted by TysonTom back in 2008 but the link to the image he references is gone. It does not seem to be in the library.

Did you reinstall the jumper wire between 2 and T?

Have you tried the DSP crossovers in the Crowns yet?

This is a great example of how the truth can change. Good solution. The Crown XLS series are getting more popular on this site.

No No The Hivi mod attempts to mimic the original tweeter by rolling off at just below 5000 hz. The tweeter in these speakers reproduces only sparkly bits, cymbals and high harmonics, zero musical notes. The 2ax mid driver, if working properly, doubles the tweeter as far as it physically can. The solution should be to increase the mid and tweeter controls to max and begin adjusting from there.

Are you sure the other tweeter is the 3a version?

Yes. They should be rebuilt in pairs. Msg @royc or @chris1this1.

If 4 AR3as then not many receivers. Find one that is rated to operate continuously at 2 ohms.

If these are the published specs then not even 1 pair.

Have you looked at the home page? Nothing wrong with Klipsch but being from Arkansas, it doesn’t fit the profile for forum topics that was established for this site over 20 years ago.

I have sets with original grill cloth. One set has 24 the other is 18. The fabric on all four grills is slubbed linen.

The main difference is the new fabric does not appear to be slubbed. The yarn thickness is too uniform.

The 5 is a paradox. While there is a solid argument for the above sentiment, properly working 1s, 3s and 3as always get more love from the marketplace. Are you in the US?

That looks like a Barzilay Wall unit. Was it for sale?

Seems like a bit of an endorsement. I like mine too. I see new ones now have a 6 year warranty.

How is the Crown XLS working out?
