Ditto what Scott Valley stated.

As an aside, I'm always interested in seeing the various mods for the AR3a speakers. It's also nice to know that there are others that evidently share this interest and feel that the "Classic" AR's are still able to deliver the goods.

Best Regards,

Best sound of all!

TerryO,

Hi TerryO,

I have had a lot of speakers in the past - JBL 2203, 2213H, 128 H, 124 a , and others , Infinity Kappa 7 , IMF transmission line TLS80, KEF Coda, B139 , Tannoy dual Concentric, and many more. Still the AR9 , in my opinion, beats them all ! The punch and the perspective, places the AR9 in a category for them selves!
I use the AR3a because of the space I have available today , and they do the job great. I still wonder how they did it with the 11" woofer? - have been looking very closely to the "soft" cone of the AR 11" woofer, and the fibers is placed geometrical 90 degree on each other like many others. The softness of the cone must have something to do with the "break up" and the acoustic suspension. I need further messurements in 3D scope before I know for sure.

Bottom line is: " Never heard a 11" woofer with the same punch"!

Try "Dead Set" Grateful Dead in vinyl - you will not be dissapointed!

That's why I am making my "personal" AR3a "Improved"
