Moving more air with a sub will certainly make a minor difference, but any way you look at it, your speakers are like 83db sensitivity. Anything playing that has a lower gain, is going to give you some issues. If you are truly happy with the overall sound, I would look for a player with variable output... if not, a Preamp with a variable output..
subs for LFT-8bs
In a recent post there was a recommendation for Rhythmik subs to mate with these speakers - are any others recommended? The problem I am having is I use these speakers for both music and movies -powered with quicksilver M60 monoblocks. With dvds I have enough power but with blu-rays I am barely getting by - I was hoping the subs would improve the efficiency of my amps. thanks.
