volvotreter 38hz tapped horn

I have build one of the volvotreter subs with the w6-1139SI. See my gallery

Although these subs go pretty low with this 6.5 drivers. I could not manage more then 17.6 volts into it and it lags in the 'loud' department meaning you need to build at least 3 or 4 of them to make some impression. I say up the ante and go for example the martinson THAM10 HT (or HTL)
