does anyone have any opinions of this cab? it seems that 4 12's would be good for a 5 string player such as myself who wants more bottom, as it is advertised as having a frequency response down to 25 Hz. but it is stated on peavey's website that the cab is tuned to 50 Hz. wouldnt it then be bad for the drivers to put any sort of frequency below 50 Hz into the cab? like a 31 Hz B struing... is this poor design or am i just paranoid?
