This is well known to be an excellent sounding drop in replacement for Linaeum tweeter speakers like the RCA CAT 40-5037, Optimus LX5, Optimus  LX5II, Optimus 77, W-LX5, etc.  “They fit perfect.”

Also drop in replacement for Paradigm, Boston Acoustics HD5, PSB Alpha B1, EAW UB12S, Advent Mini, Polk Monitor 50, DC130A-8, DC130AS-8, ADS L300C, among many others with this hard to find “pincusion” shaped frame.

Chances are if your driver measures about 5-13/16″ diagonally, 5-3/16″ across the frame, and your throughhole is 4-19/32″ or a little bigger, then this is what you have been looking for!

If your woofer is rear mounted on the front baffle, you need at least a 116mm hole opening in the baffle so the woofer rubber surround can move freely.  That is about 4-5/8″.

We receive constant feedback from our customers on how good these sound as a replacement driver. They fit AND are an upgrade!!

For the Optimus Pro-LX5II, the woofer is rear mounted and the opening is not large enough, the woofer surround will slightly rub against the opening edge.  A customer was able to make this work by adding a 1/4″ gasket to the front of the woofer to have it sit further back from the baffle. You could try using foam gasket tape to create this clearance.

Possible alignments:

0.3 cubic feet sealed with 25% polyfill stuffing for a 3dB down of 77Hz.
0.4 cubic feet sealed with 25% polyfill stuffing for a 3dB down of 75Hz.
0.4 cubic feet sealed with 25% polyfill stuffing for a 3dB down of 76Hz.
As you can see, this woofer is going to perform well in pretty much any sealed box.
