Any comments on the L1M2 with new "Pro" B2 using a T4S?
I don't believe the Sub 1 or Sub 2 will be compatible with the L1m2. The B1 and B2 are bass units where the Sub 1 and 2 are actual sub woofers that could be used with other speakers.
You can just use the bass line out of the Model 2 - or you could go directly
into the Sub2 and use the high pass filter or even the S1 filter to go into the Model 2
Had forgotten about the bass output from the power stand. I might consider getting a new Pro sub to go with my L1MII - I can't see the new pro column giving me any more tonal quality - just added wattage I don't need - but the drop in Hz response in the new Pro sub would probably be more noticeable.
