GR Research NX-3 Tower Speakers

August 17th, 2026, 12:58 pm

I built a pair of NX-3 Bravo Towers based on a GR Research kit that provided drivers, crossover parts, internal wire, etc., and cabinet plans. I successfully veneered the cabinet with walnut and am in the process of burning them in.

A detailed thread can be found at the Audio Circle site under the GR Research circle that is titled, "NX-3 Bravo Towers, Standard Build." <https://www.audiocircle.com/index.php?topic=193991.0>

It's an MTM arrangement placed in a slim (8" wide) transmission-line cabinet. Sensitivity is 91dB, Nominal Impedance is 8 Ohm, and the Crossover is 950Hz. The base extends down to 40 Hz.

The NX-3 towers look great!

I still really like my NX-2's two ways with the external XO.

Dang, those look good and I bet they sound even better.
Transmission lines are a difficult build, you really put some work in on these!

I could only wish for Guy's skill in making beautiful things from wood!

Well done, Mr. Guy!

Can't wait to hear them!
