I need honest opinions on which subs would be better to go with? 2 RF 2215 or 2 Adire's Tempest? I pretty much have it narrowed down to the two subs, but im open to suggestions. Im looking for SPL and than SQ. I already have 3 jl 10w3v2's in a ported box, but there not hitting hard enough for me. I would have 850 watts rms to supply to them @ 2ohms. AMP :RF X6 if you were wondering.
