cornfedboy, i usually agree w/yer comments, but not this time - as the best, most expensive full-range speeks usually come *standard* as monitor/sub set-ups, i don't tink yer argument holds much water here. i tink coherency of sound is *much* easier w/the low frequencies separated from the monitors - ewe can set up the monitors for optimal image/soundstage, & the subs for optimal bass response. when they're in the same box, one is usually compromised.
slartibartfast, i tink yure on the rite track, especially if ya like the sound of yer b&w's. definitely get two subs. personally, i like the vmps larger subs, & the marchand xm-9 deluxe crossover. great flexibility, great transparency, unbeatable true bass response - accurate, deep, tight. paired w/any decent used solid-state amplification, ewe could spend over twice as much money, & not get as good a bass-response, as well integrated w/yer monitors....
my opinion of course... ;~) doug s.
