So I have been leveling my HSU10 from parts express. I have it essentially cornerloaded and I have been looking at the RS SPL meter with various frequency SIN waves. I started at 10hz and worked my way up. I have the RS SPL weighting set to C and range set to 60hz with slow response. The whole system is set to a 75db reference level and as of yet I have not EQed any frequencies because I'm not sure if the SPL is working properly at low frequencies. Reason being is my in room bass response seems to be -1db at 15hz and -3 at 10hz in room measured from my seating position with a 229$ sub.
Either I live in gods acoustically treated apartment, my SPL is perfect for high frequencies and totally deaf to low ones, or this sub was a hell of a bargain. It's not particularly visceral or punchy in your face but the frequency response of this sub seems amazing. I'm kind of new to this whole SPL thing but I have read a bunch of different how to threads on how to use the SPL and as far as I know I'm using it right. The 10hz sin wave goes up when I turn the volume up and down when I turn it down at -10db on the volume knob 10hz is 63db and at 15hz it is 65db then 66db from 20hz to 20khz. I also confirmed these result with the bass treatment 10hz to 22khz frequency sweep on DVE. Can someone explain to me what is happening?
