I've been playing with a friend who has an L1 system (the original). He has one Bass Module. Overall, for the use it is good at (even coverage at moderate levels) it is pretty good (albeit it still a little lacking in low-mid 'presence').
But I feel, for a $2000+ sound system, that no reverb, no auxiliary ins and outs (no RCA's to connect a recorder or break music device to) and rudimentary controls are definitely bullsh*t. Heck, little $300 mixers got multi-FX, RCA's etc...
