Hi all! I'm a noob with using a Matrix SS Poweramp. I know that you are supposed to dial in the settings in the speaker page. But I still couldn't get my cab to thump like when Im using a tube poweramp. Im thinking I just don't know how (and I dont understand) those setting parameters and what they do. I came across a forum discussion here with Cliff's math formulas and all but I think I'm missing something. I'm using a Genz Benz GFlex 2x12 with my Matrix GT1600FX. The Gflex has a pair of 12" custom Eminence speakers. I think they are OEM Legends that Genz Benz used for George Lynch. Anybody got the values I should input in the speaker page for the GFlex speakers and cab? Speakers say Frequency +/ 3db 60-5K Hz. Help?
