With the trend towards bass guitars with fundamental tones around 31Hz, together with low kick drum tuning, we should be looking closer at reproducing these lower frequencies accurately in the PA arena. I quite often have to deal with kick drums tuned down around 40Hz or lower, and with my current PA gear, have to either retune the drum higher or just contain and process the harmonics. I am currently working on a REAL 35Hz PA sub.

At this stage I am not convinced with the need to go quite as low as 20Hz, but certainly believe we should be trying for maximum performance to at least 35 or 30Hz, rather then the common 50 or 60Hz. To this end, I am currently working on a wide range bottom end bin which so far models fairly flat from 35Hz to 200Hz (block of 6), and will get a chance to prototype within a few months when shipment of the appropriate Beyma drivers turn up.

Chances are that when you have problems with kick drums it's not at 40 Hz but at 80 Hz. I've found that when bass levels are perceived as excessive, to the extent of pounding your chest so hard as to literally take your breath away, the bulk of the energy present is around 80 Hz, not 40 Hz. When you retune the drum higher what you're really doing sonically is pushing that all important second harmonic higher to where it is less offensive.

I'll provide a head count to Eminence to give them an idea of interest in this improved MAG12 subwoofer. So please write to me if you are interested in this and I'll pass the word.

But if you can stipulate that several horns be used, then each one can be made a little smaller and still get the job done. For large-scale setups, that becomes an option. Or if the installation can be made permanents or semi-permanent, then you can really come up with some neat large bass horns. And then there's the reality that 40Hz is a pretty good goal for bottom end, and if bass is solid down there, it generally satisfies completely. 120dB between 40Hz and 80Hz sounds very powerful indeed.

Since im doing electronics,it involves ALOT of PC work,my CISCO networking is all online stuff,their tricky,u cant copy and paste the notes :P gota take screenshots of all the crap ur supposed to remember:P
