I have always run either combos or small stacks in small to medium sized rooms, and it's always been a bit hit-or-miss as to what sounds best in what environment. I currently use a small MarkBass stack (CMD121P combo plus NY121 extension) for most of these situations, and I can usually set up in such a way that the rear boundary becomes an asset to the sound. There is one room we've been playing with greater frequency, though, where I'm very constrained to a spot about 8-10" in front of a glass wall. Not an optimal situation with my rear ported rig, and it's an absolute bear to dial in a decent sound. It occurred to me that this would actually be a great application for an infinite baffle cab; however, I'm not dragging an SVT 810 into this environment. That stays home unless called for on a larger venue or outdoor gig. All of which is the setup for the obvious question: does anybody have experience with portable infinite baffle cabs? Alternatively, do any of the bass cab manufacturers even make such a thing? It goes without saying that such a thing could be built, but I don't think I've ever seen one for sale. Something like a 1x12 or 2x10 IB cabinet, that is. Thanks in advance for the voices of experience.
