the majority of the threads i've read suggest to EQ at or near flat on amp and bass settings. but for the sound i'm looking for, and the feeling of chest thumping, fully body massage bass AND punchy tone, the only way i can get that is by cranking the bass EQ knob to the maximum, and the midrange. I'm talking about total body vibration. it's an indicator that i need a more powerful amp, but the sound is extraordinary. i don't ease up on these settings as i haven't heard any strain on my speakers, and my 810 is rated at 800w continuous power handling. i recently installed a black widow in my 215 as well. for what i need to do it sounds great, but i wonder how many others run their amps this way. how many TB'ers disregard the safe and sensible flat EQ, have you damaged your gear as a result? current setup is an SVT-CL @ 2ohms > Ampeg 810e + Traynor 215. as a side note, i've been thinking a lot about trading my SVT-CL in for an SVT 4PRO. i haven't found much info on how much volume i'd gain by doing so. ideally i'd rather not have to crank the EQ as i do on SVT-CL, but i worry about the tone i'd lose without an all tube amp.
