Ok, heres my setup, dual 20-39CS and a Samson s700 amp. Sounds outstanding. So i thought that i'd add the art to tweak it to perfection!! However not being to smart when it comes to eq's my results are very poor.
I initially set my spl meter on a tripod at the sweet spot at ear level with the mic facing up and slightly forward.
I then set the H.P. filter at about 20hz clser to 15hz because the dials not marked. The L.P. filter is cranked all the way up as this shouldn't come into play right? I have the level at about 7.
I then inserted my Styke audio test cd and ran sine waves from 20-80Hz at the same volume level wrote down all my reading with the sliders set flat and used the radio shack correction chart to get the real readings.
I then started with 20hz setflat with the volume at about the 8:00 position i had about a 80db reading, so i didn't try to adjust this one i just tried to get all the others to 80db or as close as possible.
I have a really high peak at 40hz in my room, after all the adjustments are done, i went back and rechecked all the readings and it seems that everytime you move 1 slider it has an effect on the frequencys prior to and after, does that sound right?
Anyway the impact of the subs just isn't the same as it was before the eq was installed. especially with music cd's the bass has dropped tremendously.
Have i set something up wrong? any tips you can help me with here, all help would be appreciated.
Thanks
Craig
