What the heck is this cab?

Man how cool would it be to rip a sick solo then turn around and bang a chick on top of your cab. I wonder if I could rise to the occasion in front of an audience both for the solo and for the banging. That's what this add is implying, right?

It's part of a performance anxiety awareness campaign, actually.

Ah yeah, I remember going through the threads on Mitchell Donuts. Have had good results with those, and the physics seems to check out, unlike the tone bra and other similar ones.

JM was a pretty accomplished guy technically when it came to speakers. at the time beam blockers/bras set off quite a firestorm, i was using turbosound powered PA speakers with dual concentric tweeter & mid-low frequency drivers in our outdoor amphitheater to address the phase cancellation from offset arrival times normal to traditional 3-way PA boxes.

Jay and i engaged in forum chatter about the benefits of the tweeter in the dual concentric system minimizing phase error by reducing the depth of the cone/source thus eliminating the highs from radiating and reflecting at multiple points off the cone which the beam blocker was actually correcting, not just diffusing/attenuating a laser-like beam of highs—
and further phase error correction gained by aligning the tweeter and mid/woofer on the same axis versus conventional tweeter horn up top/mid and low drivers below in a line.

later i believe Jay ended up using that dual concentric design for the 1st gen Atomic CLR FRFR speakers he helped develop if i’m not mistaken?

Egnater folks maybe used the tone bras as i remember Frank Lamar mentioning the merits of them? @Jeff Hilligan would remember…

back before my permaban from TGP, there were many discussions about "beam blockers" or whatever they were called, that supposedly diffused the beaminess of guitar speakers. Never saw the point in them...I think Weber used to make them?

I remember seeing bands that would tape CD's on the front of their cabinets to sorta do the same thing.

Yes I remember the JM discussions on TGP, he was very knowledgeable, and I recall he worked on the original Atomic FRFR cab/speaker designs too.

I had a Bose L1 system with two bass modules that worked great for guitar, bass and keys, for my earliest guitar modelers: Axe Ultra, Vox Tonelab, etc. I'm sold on linear array systems, but not Bose since my L1 system self-destructed after not being used for a few years, when I took it out again it had bad noise, and feedback, that I was unable to eliminate.

I went back to powered PA cabs and subs...but If there was a cost effective linear array system with good low frequency response, I'd get it. The only systems I'd want are cost prohibitive based on my pedestrian needs.
