LOL yeah, the Harbottle/Funk stuff is pricey (but about as good as it gets). I'm more a fan of multiples no matter the particular sub, tho. I went DIY for my last several subs, partially to save some cash but also for the experiences (with woodworking as well as the subs themselves). Might also consider Hsu and SVS, too.Im not sure these fit within my price range when trying to go duals. Unless youd like to expand on things why something like a FUNK single would be better than rythmik E15 duals.
edit, nvm none of these are remotely near my budget for a single. soooo not sure on the recommendation?
