do a search for vmps on the a-gon forums search page... i've posted once or twice about my high regard for their subs. ;~) i think you'll have to spend 3 times or more retail, to put together a subwoofer system that will come close to a system based upon the vmps subs...
re: their other models, i am looking forward to auditioning a pair of the rm-40's at my dealer... i hope they're the same bargain, even purchased new, as the subs are! :>)
but, take my adwice w/a grain of salt - remember, i like analog software! ;~)
