I wanted to ask if anyione has any experience with the Delta Pro 15A? I commissioned a 100 watt Portaflex clone and gigged it last week with my 3012LF loaded 2x12" LDS cabinet. I had the amp turned way up. It dawned on me I probably need a more efficient cab setup. I was toying with getting a pair of single 15" cabs loaded with the Delta's. They have a high sensitivity and go up to 4k. I was wondering if anyone is using them in a similar set up and thoughts on the tone. Is the single speaker enough or should I add a 6" mid? Not really looking for a fearful, just trying to put together the most efficient pair of cabs I can with a nice articulate tone. Not really a modern sound but still good definition. Thanks in advance for your help.
