[QUOTE="Art Welter, post: 50920, member: 52"] Re: Home Brew powered sub. Douglas, Price seems pretty good, what kind of voltage can the amp do before packing up? You could determine the amp EQ by testing it independently at a low drive level with a load resistor (a space heater or toaster work well if you don't have anything else handy) and some clip leads to your Smaart input to determine what the plate amp is actually doing. A 6db peak around 83hz would be an odd thing to design in, but Quilter is not shy about creating "bang for the buck", 80 Hz gives a good "boom boom" effect. Art [/QUOTE]
