I don't know what is on the market now. I would look into Ashdown among others. Between 25 and 40 years ago, the 2X15 cabinet ruled. I got mine at the tail end of that era, just before, or overlapping when the 4X10 became "it," or in combination with an additional 1X15. Back then, I had an SVT head, but I never cared for the fridge. So I found a gutted Peavey 2X15. I put casters on it. I added fiberglass insulation to damp cabinet resonances. I made sure the ports were good. Then I installed the best value-for-money drivers at the time: Carvin. Two 15-inch, 8-ohm drivers wired in parallel for a 4-ohm load. I gigged that combo until I got tired of the weight of the SVT and the cost of tubes. Then I purchased a Carvin ProBass 300 for the same cabinet, and gigged it until I sold the cab. I loved the tone and projection of a 2X15 driven by 300 watts. Finally sold the cab and got a SWR Triad, "stereo speaker on steroids."
For some of my current gigs, I would still dearly love to crank a 2X15 cab, but I'm not going to spend the $$$ or risk my back for the weight or size. On the other hand, the Carvin Pro Bass 300 and Triad are still the rig for my band's rehearsal hall, with a new crossover for the Triad to make it much more efficient.
