Since I play both guitar and bass on gigs, I really haven't had much interest in Matrix, Atomic, Friedman and PA speaker FRFR solutions as that's a pretty significant investment to only cover half of my needs. While Helix through my 12" Mesa bass cabs is fine for bass, that's not the best FRFR guitar solution being a little hollow and boomy.
I ran a search for "FRFR guitar bass speaker" and found that AccuGroove has an FRFR solution. I cant say that it's new and revolutionary, since honestly their FRFR cabs seem to have exactly the same specs as their corresponding bass cabs. I sent a message into AccuGroove support asking for an FRFR recommendation for Guitar and Bass and the difference between their FRFR cabs and bass cabs.

I can certainly see how their design using a 6" midrange to fill out the sound and the dual soft-dome tweeters to tame the highs harshness and beamy-ness could work well.
I cant seem to find pricing on them as they seem to be dealer-centric.
I watched a few videos on them. It looks like they have been used by Fractal Axe users for a while. The guy in the videos I watched was using a Crown power amp. I would probably just use the power sections of my Mesa M9 or Walkabout.

Personally, I am interested in the
Latte FRFR / Tri 112L Bass (videos sounds a little boomy on guitar, similar to me running Helix through my Mesa 1x12 & 2x12 bass cabs)
Espresso FRFR / Wedgie Bass (videos sound tighter, less boomy)
Anyway, I thought this may be helpful to the guitar/bass guys that would like an all-in-one solution. If anyone has experience with AccuGroove FRFR or bass, please chime in!
P.S.: This is not my rig ...and sorry for the AX8 in the image...i didnt have the time to photoshop a Helix in there :)
