I'm sorry but you're just wrong. There is a filter in the xls1500 I believe but it is somewhere between 10 and 15hz, nowhere near 100hz and barely audible...more tactile. . If you search my posts I put up a graph comparing the xls1500 to the peavey ipr27500 and the difference was down low. The xls sounded great driving sealed subs except for the ULF roloff. They sound great driving the mains.
