[sdiy] bass pedals? How low is too low?

[Ken Stone]

Well, being the idiot I am, I want my organ pedals to go down to 64', 10Hz.
Of course I won't be able to hear it either. What I am doing is using a mass
driver mounted in the stool of the organ, so I can feel it without driving
the neigbors nuts!

>>The lowest note of Bass Guitar is 40Hz... organ pedals (the super long pipe
>>organ style ... 32') can go to 20Hz.
>>Almost no speaker can reproduce 20Hz reliably.

>I agree. Most of the high-ticket powered subwoofers on the market
>barely do 35 Hz. In no other area have I seen so much spec inflation.

>>those bllsh!t "bandpass boxes" do not count in my book, unless you are
>>willing to build one for each note.  The extreme "Q" of these systems makes
>>them suitable for shaking nearby buildings from a car
>
>Which appears to be their only real-world application.
>It's a billion-dollar market too.

>"Hahahaha! Stupid Americans want car to boom!!
>We sell them junk woofers with high Q in sealed box!!"

>>Folded horn designs like the Klipshorn (sp?) that use the room walls as the
>>final 'mouth' of the horn might do well also...
>
>A Klipschorn isn't practical in most clubs or other venues. Rarely do you

>with corners made of 8x8 plywood sheets, with questionable results.

>Community Sound makes a horn with an 90-inch by 90-inch mouth
>and a flare frequency of 34 Hz....it only weighs 750 lb...

>What to tell this guy? He needs to shop for subwoofers, and take his
