hi all, im equalizing my sub using a dcx2496(also lowpass) , and its doing a fairly good job.
my room some "small" problems, concrete building and minemalistic decoration....

my concern is music, no ht duty!

my sub is a passive 12 dvc dual voice core unit, driven by both channels from a nakamichi pa-5s2 that suplies around 2x 490Watts in 2ohm, so i should have some head room to spare....


here is what i gott to work with: rew measurements with no eq or sub crossover filters aplied yet.

first is :frontspeakers only:
second is: sub only
third is: front and sub(no eq or lowpass)


what would you recommend, how do i attack that curve?

best regards

Hi Wayne and thanks fore the reply.

that I understand, but what slope/type but/bes6-48 should i use, and what would a good crossover point be, thats proberly the first question i need help with.

both with taking frontspeaker slopes into consideration and where it would be sensible to put the crossover when u think about housecurves and good equalization with no more +-15db gains than i absolutly have to use.

when i have tried to equalized it over the past couple of days, I use (in my mind) way to much big gains and -gains, and i cant seem to find a way around it!

best regards

Given your speakers are showing good in room response right down to 45hz, why not try that as your starting crossover point.

Musically, I have found from time to time I prefer the sound of a speaker doing what it is supposed to do, with the sub just coming in where the speakers drops of.

If your not so struck on the 45hz crossover, then increase it upto and including the standard 80hz to see what your ears think of the difference. I wouldnt recommend going much over 80hz with just one sub, with 100hz being the max.

Chances are experimenting is going to be key, especially as when it comes to music, ears differ much more in taste/preference than they do with movies soundtracks. Try just running your speakers at their natural level rather than playing with tweaking their response to start off with. If your trying to pick a good crossover point then you dont want to over complicate matters by altering to much at once, it tends to confuse in my experience.
