that's kind of a moot point. There really isn't any mainstream music that plays 20hz tones at any kind of audible level... When 20hz does show up in a song... its recorded at very low volumes because its basically wasted bandwidth on a CD as nobody (read: .1% of the population) has equipment that will play that low (at any kind of volume).
The few recordings that will play that low at moderate to loud volumes are test tone CD's and Bass Mechanic CD's which are designed to show off a subwoofer setup.
You could get some 8's in a ported box to belt out some authority at 20hz... Not going to break SPL meters or anything, but keep in mind, the human ear sucks at telling the difference between say 120dB & 140dB... once you get past 100dB the body is doing more of the gauging of the volume than the ears are.... Feel the clothes and hairs shake and such. Mine will play done to about 26hz pretty well... My box is tuned to 28hz. If I made a slightly larger box (go from 1.2 up to 1.5-1.75cuft) and tuned it to 20hz it'd belt out 20hz tones, THO, i'd lose total volume on the 30-80hz range. Because i'll never hear a 20hz tone playing on the radio... tuning below 30hz in a car stereo setup isn't recommended usually.... (tho they can be very fun to play with and show off).
SQcomp... if we ever meet up, I'll have to show you what two lil 8's, 150rms, and a lil john CD can do.
