More stupid sub questions...sorry! I still need a decent, compact sub for the crazy lows i get with my varying filters and bass synths. the Bag End ELF system sounds outstanding but could I not just get away with an Acme B-2 for that huge 18" deep bass thang? Maybe a B-4 but I am scared of the huge power I would have to arrange for it. The Bag End D12E-D dual 12" ELF sub only needs 400W @4 ohms, quite do-able, no? Acme claims the B-2 to be comparable to an 18"... Bass NW sees used ELF stuff all the time but a wee B-2 would be very nice, if it does what they say. I could run a crossed over signal from the back of my Mesa M-2000 into a small (maybe sing.space) power amp for the Acme, lows only. A much cheaper option. Opinions? Thanks!
