Well, I've held off giving any indepth reviews of my LDS 112 cabs because since I got them, there was/is something not quite right about them... a mild distortion when I play low notes, especially 'A' and 'G' on the E string. At first I thought it was just the crappy sounding acoustics I have to put up with at the rehearsal studio I usually frequent. However, I've used them in about 4 or 5 different rooms now and I definitely felt something was wrong. So I grabbed my UL112 and did some driver swapping. I put the driver from the LDS (3012HO) into the UL112 box and the problem disappeared. I put the driver of the UL112 in the LDS box and the issue was there. The issue is what I understand to be chuffing. There is a hell of alot of air coming out of the two circular ports of the LDS cab. It sounds like a sheet of paper that is being vibrated at a very fast rate. Initially I thought it was some form of distortion but after careful listening, I am fairly certain the sound is coming from the ports. Its happening on both cabs so I'm guessing a design flaw? Is there any way I can fix this myself or am I going to have send the cabs back?
