Hey! Right now I've got an SWR Super Redhead with a Yorkville 15 extension. I was thinking about getting the 18 SWR and drop the 15 for some more bottom. But then I ran across the Acme website. I was thinking about the 4x10 sub, forgot the model number) and the B2 to replace everything. I've already got a 1200 watt power amp at home. I'd just need aa preamp then. Whatcha all think?
