Thanks for your reviews, however I don't understand #5. One of the features of the L1 is that it is highly adjustable for dozens of setups. The system one has many presets in the base unit, plus 3-band e.q. on the controller.
System II has a totally programmable digital mixer available - and it IS necessary to have.
Using this controller, you have parametric and conventional e.q. available for every channel.
My Bose has sizzling highs and gut-thumping lows.
