[QUOTE="spoonraker, post: 2762591, member: 570956"] First of all my amp is a Monoblock Cadence ZRS-9 pushing 1000W @ 2Ohm to a ... don't laugh... 12'' Audiobahn Eternal dual-4ohm sub. I understand the gain, lowpass, and subsonic filters no problem, and they work exactly as I'd expect. My problem lies in the bass boost knobs. There are two knobs, one is Frequency, and one is boost. Frequency ranges from 50-80Hz and boost is 0-15dB. Now I understand that the frequency is the center or most amplified frequency, and the dB is the amount of boost to that frequency, and there is probably a curve centered around the frequency setting that slopes down to normal....anyway...here's my question : I thought that the bass boost knob was an option, but when I turn the boost down to zero, I get no bass at all. Well I get enough to almost be heard over a pin dropping. I'm getting into sound quality and looking to get a more even response, which is hard to do when in order to get your sub to be loud enough you have to boost your amp 15dB, which is centered around a specific frequency, creating a blatant unevenness in the bass. Is there a way to just boost the volume equally, or is this just a weird amp? [/QUOTE]
