will, i only had experience w/the rel strata - cheap by rel standards, but still more expensive than the spendiest vmps. i'd rather have *no* sub in a music system, that that one... i don't do h-t at all, & vmps is my choice for a music-only sub system. if i had $6k to burn, i might consider auditioning a pair of bag-end subs, w/the two 18" drivers per sub, combined w/their top-line elf integrator, & a couple nice amps... may be as good... ;~) ask brian cheney of vmps - he's quite forthright about what's good. on his website, he sez he'll even tell ya which subs to consider, if you're not interested in the vmps, but he also sez you should expect to pay at least $3200 each. :>)
