Ok,
I've tried theses Beam Blockers and they do indeed cut down on the 'beaming' effect from the speakers, but with the new Celestion Copperback 250watt Neodymium's, the beaming issue is nowhere near as bad as it was with Celestion Creambacks, Goldbacks, and Vintage 30's that I experimented with. The Copperbacks are much fuller and less focused in terms of shooting a beam of sound out in a stream. Also, my EQ's are no longer maxxed out like they were with the lesser (although popular) Celestion models.
Here's my previos amp settings when using Celestion Creamback, Goldback and Vintage 30's that I borrowed for testing from a colleague.

Here's my settings from yesterday's shakedown run:

Even after the Headfirst/Ivanberg Modifications, the Creamback/Goldback/Vintage 30's still required slamming the EQ's to get anything even remotely near a decent tone, and like many speakers that are chosen for "growl" (which is inefficient cone distortion) and because they offer "spikes" in the audio spectrum, it's to be expected.
I'm gonna offer these Beam Blockers to anyone who wants to try the pair of them for the price of shipping.
PM for details...
