Shok IndustriesTriton 15" Dual 4 ohm
Some of the best subs i've ever owned in their price range. I don't know what the previous reviewer was talking about, because these things shine in the low end. Not to mention he overpowered them by 1kw in a box that should've been closer to 3 cubes at that power. Put 500-1000 watts to these in a 3-3.5 cube box tuned in the low 30s and you won't be disappointed!!
