Hi everyone! I'm considering the purchase of an M&K VX100 sub as i've found one in good nick second hand for £500. I use my setup principally for music production and I want to supplement my AVI Biggatrons with a decent sub. Getting basslines mixed right on the biggatrons is a very hit and miss affair due to their rapid tailing off around 50/60 hz. But.... a) I use a Bryston B60 which has no dedicated sub output. Would the only option be to disconnect the pre/power connectors, replace them with two y-splitters and connect L/R plugs to the amp and the other two to the sub? Would this adversely affect sound quality? b) should i be looking at different brands/models of sub at this price? c) should i just save my cash, trade in my biggatrons and buy a pair of beefier PMC/ATC monitors? if anyone can help me i'd be over the moon.
