I would go with the JBLs. At the moment, they are
on sale at Sweetwater for $250, which is a great price for them, and makes them the same as the mackies. The Mackies are very good, but JBL makes some of the very best drivers that you can buy. The wave guide on the tweeter looks like a better match for the 8" woofer, and the woofer is going to be very serious. I do think the LSR is a step above. Harman's research facilities and staff are one of the best if not the very best in the audio industry, and the LSR line is one of their babies.
