Re: Brought home the Triple Rec Reborn and picked up a couple cabs too.
Yeah those over-sized cabs (especially the true straight-baffle bottom cab) really open-up the highs and lows.
It can be good or bad depending on a million-and-one factors.
Have you tried the mesa 412 and 212 together?
I really like the recto 212 stood vertical combined and the 412 flush on the floor (no wheels) for the triple reborn.
Also really looove the rect0 212 on the floor combined with my avatar212(k100) cab stood vertical.
Most of my guitars/pickups lean towards "modern"(lol) and/or "mid-focused", so maybe that's why it works well for me.
edit;;,,,,,,,It actually wouldn't take much to modify an oversize cab to have traditional-size internal-airspace.
(btw,,,,oversize slant only has a small amount more airspace than a traditional bottom/straight cab)
Boards could be cut to specific sizes and screwed/glued-in, or even better; velcro could be glued to the inside of the cab's bottom or back and the ingoing board's bottom to make it an easily reversible change.
Probably not something for a touring/gigging cab, but for a studio/music-room cab it might work well to tighten the lows and get more mid-focus from an oversize. Might also just be the perfect recipe for internal rattles. lol
