I took a long hard look at SVS subs many moons ago. The biggest seller for deciding on Axiom was in part the ability to have it blend with the other speakers. For a long time many sub makers had black, black and black. I had little interest if they provided no colour options or at least something other than one option.
A friend of mine ended up buying the SVS 'water heater' at the time. It pounds out sound well and was better than the EP350 we had for SPL and 'slam', but the EP350 was way prettier.
