A friend gave me a Trace Elliot 1x15 without a driver. I want to make it sound like a B-15N, but louder. Lots of umph in the 100 - 200 hz range. I have a Walkabout head to drive it. I downloaded WINISD but need a starting point for drivers to look at. The cab dimensions (interior) are about 17"x15"x22" ~ 3.25 cu ft.. It has two 4.5" diameter ports (that could be plugged). Any suggestions for a nice vintage tone? I'd prefer a 4 ohm driver that weighs 2 pounds but am more interested in tone than weight or impedance..
