Post Subject: clean and loud, and stereo subsPosted by Dominic on: 2/18/2007
The rule of thumb is that you can't localise sounds below 80hz. The classic experiment is to use a sub with an adjustable xo point and adjust it untill you can't tell where it's comming from. That doesn't change the fact that seperating the bass into two channels is better. There was a study not long ago at a university that reccomended two channels for subsonics, i'll see if i can find it in the next little while. It still has something to do with dirrectionaliy, and doesn't even address the fact that any source material with LF info on both channels would be best served by not mixing them. FYI  5.1 is .1 because the subwoofer is there for sound effects for movies. um i only mention that incase you didn't already know. I assume you know well enough that the reason anyone can hear their sub is because it's not designed for music, and or it's already crossed too high.

More importantly; what's 'clean and loud' got to do with music?


More directly related to your project;
 What had you in mind for your (for the sake of argument) 'imaging' sections? Do you think you can get interesting results out of contemporary road gear? That seems to be the general dirrection your friend is pointing you. I wouldn't say it can't be done but i also wouldn't necessarily be optimistic. They are designed for large power handling and that has repercussions for moving mass and magnetic gap and of course the amount of material in the crossover, i would assume that you'd not be using any stock crossovers though if you really wanted to bend the products to your will, music, and room. The professionals are wise to the ways of signal correction before the power amp but, but, their main reasons are relate to not having to maintain heavily worked crossover components times 50 cabinets- crossover before your amps with a DSP and you only have to have one DSP, rather than 50 crossovers sealed inside your cabs. Another good reason is that it makes adjustment per venue simpler, they can do their notch filtering etc as the space demands from the mixing desk. And other such pleasantries. What it doesn't mean though is that you will necessarily get musical benefits.
