Was told this unit should be in the my local music store within 2 weeks. It's a 400 watt Yamaha. I'll quote the following:
The high frequency section of the MS400 contains a single 2-in. titanium compression driver coupled with a 90° x 60° constant directivity horn, and is driven by a 100-Watt power amplifier. The 15-in. transducer, equipped with a light neodymium magnet driven by a 300-Watt power amplifier, produces efficient mid and low frequency reproduction. Utilizing Yamaha's EEEngine Technology, the internal bi-amplified system maintains efficiency, low current draw, low heat and reduced weight.
In addition to uniform coverage and highly intelligible audio, the MS400 provides a wide (50 Hz - 16 kHz) frequency response. Cabinets feature independent MIC and LINE inputs, each with its own separate gain control. A 2-band EQ (Low, High) provides basic, effective tone control, while a Master Volume controls the overall output of the cabinet. Connectors include a balanced XLR for MIC input, plus 1/4-in. and XLR connectors for LINE input. A parallel output jack allows multiple speakers to be daisy-chained, with a headphone jack supplied for monitoring. Constructed of durable polypropylene, the MS400 weighs just over 50 pounds.
