RE: Powered Subs



With Max etc,  you can produce sounds below 50hz that some subs can
reproduce.  

But don't fear, I believe the low frequencies won't damage the 12" mains.
the mains will reproduce only harmonics of the fundamental low notes, 
rather
than the fundamentals themselves.   That's why you can 'hear' low end even
on a car radio without sub woofers.  The harmonics kind of fool your brain
into perceiving the fundamental sound.  You just don't get the full impact.
Besides subs, you need room acoustics that will support low frequencies.
This is where room dimensions , shape, and acoustical treatments can really
make a huge difference.

Rick - let's use BEMF as an example. You remember how huge that sounded 
last

year, right? We could not have produced that with just the 15" mains that 
were next to the stage. We had subs on each side and they were pumping out 
the sounds in a major way.  When you have electronic musicians (guys using 
max/msp, Reaktor, etc) producing giant, almost movie soundtrack sounds in 
the 50-100hz range, two powered 12 inch cabs, or even an inexpensive home 
theater sub isn't going to do the trick in my opinion.  What I will buy, I 
will use at BEMF this year. I'll have my two 1X12 powered ElectroVoice 
SxA100s for mids/highs, but I will definitely need some low end. I'm 
afraid 
I would blow those speakers with the low end that I heard at last year's 
festival. So, the single Mackie powered sub I listed seemed like a good 
choice in this case. Sure, I would love to save myself some money and buy 
two lower end powered subs for $300 each, but then I am already at $600, 
only $250 short of the big daddy Mackie sub which is a nice piece of gear 
that will deliver low end for years and years.
