Thanks for sharing. I see the amp is only a 300 watt RMS unit. I love it when manufacturers focus on the driver instead of just throwing more wattage at the system with big 1000 watt + amps. My own 15" designs use but 240 watt amps. I rarely listen to music louder than an average of 90 dB + dynamic peaks, and could probably get away with half that power if I knew the amps could handle the impedance. Wonder what the driver sensitivity is?

What's the internal bracing like? Can you tap on the cabinet and identify where braces are?

I finally have some down time this weekend, maybe I'll post a thorough review of the UMC-1 if anyone's interested...
