Another Brahma thread....

I've found that the majority of people don't realize where "punch" really comes from initially...
Extra 80~120hz information will make a system sound extra punchy, but the majority of that should be focused on the midbass up front.

Often the midbass being used can't hack it, so it's falling back on the subwoofer. Which of course, people turn their xover down low, so have to turn the gains up higher to get that region to be boosted because the crossover has already cut down the output at that region some. That adds to the drowning bass output I see so often.

As for gains:

In the anal-retentive sound quality way...

Yeah... you should.

Higher s/n ratio when you hit the gains at the amp... use the full potential of the 5v at the deck to keep noise away.

Alright, thanks, I think I understand a bit more now.

In order to find out where my midbass speakers cross over to my subwoofer, what should I do? I thought of maybe making a CD of only test tones, for instance, starting at around 50 or 60 Hz, then going up by 2 Hz, all the way to 120 Hz or so to see where exactly the midbass is supposed to hit and the sub is supposed to hit. Is there an easier way than that?

There is no 'perfect' setting unfortunately.

I personally don't use any crossover on my front stage, and am crossed over at my subwoofer at 42Hz.

A general good setting for general listening (to me) is set the front stage at 80, subwoofer at 60 - and start working from there.

Generally speaking, try to set the front components as low as humanly possible in such a manner that they'll survive your worst listening habits - then set your subwoofer to blend in.

Ok, cool. I'll try some of that. Today I turned the gain down to the lowest setting on my amps, but I need another set of RCA's in order to control both the subwoofer level and the 4-channel amp level on my head unit. Currently my system is configured for my previous head unit, which only had one preout. There is more to be done...

But thanks man.
