Harman Kardon HK B6 I picked up a pair of these on a whim for a friend. They were $99 for the pair; unopened, although dusty, box. I haven't heard them yet, and I likely won't till I see my friend. But I'm curious, are these adequate speakers or are they total crap? Their intended use will be very modest, mostly music. Specs: Code: Maximum Recommended Amplifier Power: 150 Watts Nominal Impedance: 8 Ohms Sensitivity (2.83V @ 1m): 89dB Frequency Response (-6dB): 55Hz - 20kHz Crossover Frequency: 2800Hz High-Frequency Transducer: 3/4" Titanium-laminate dome, shielded Low-Frequency Transducer: 6" Polymer-coated cone, shielded Enclosure Design: Bass reflex Do these compare favorably to the JBL E-30s?
