Now THAT is a good deal. SKAR subs are ridiculous. But based on what you've said up to now, it's probably not a good fit. They're made to hit low low lows, not so much highs.
Also, rock/metal - 10s,
hip-hop/pop/some rap - 12s,
some hip-hop/rap - 15s
Basic buyers guide to subs. I switched over to listening to more metal recently, sounds like **** on my 12s. I'm possibly thinking about squeezing in a couple 10s, and putting in a switch to flip flop between my 4 12s and the 2 10s... how it will fit i've yet to figure out.
