Why We Love This Product!

Awesome Powered PA Speaker!

The Yamaha MSR250 powered PA speaker offers up plenty of power for your investment, not to mention awesome sound and a host of features. The 250-watt MSR250 features a 10" woofer, 1" HF compression driver, plus built-in Level and 2-band EQ controls. Its lightweight enclosure is made road-tough, and can be placed where it will be heard best, thanks to its integrated pole-mount bracket. Thanks to its versatile ins and outs, this speaker can even accept inputs from two sources. If you want clean power, really simple transport, and amazing sound out of your portable PA system, take a look at the MSR250!

Yamaha MSR250 250-watt Powered PA Speaker at a Glance:
    • Made for Heavy-duty use
    • First-class portable power
    • Versatile two-channel in configuration
    • Ferrofluid cooling
    • Asymmetrical cabinet design

Asymmetrical cabinet design
Sound bouncing around inside a speaker cabinet can have a significant effect on the sound that comes out. The biggest problem is standing waves that commonly occur between parallel surfaces. Standing waves can interfere with and color the speaker's output, thus degrading sound quality. The standard solution is acoustic insulation material inside the cabinet, which does help, but it doesn't address the underlying problem of cabinet geometry. Yamaha has gone the extra mile in designing the MSR250 cabinets, employing a one-of-a-kind configuration that eliminates parallel inside surfaces and therefore the root cause of standing waves. Acoustic insulation is also applied to effectively deaden the space inside the enclosure. Elimination of unwanted sound inside the cabinet means that optimum sound can be delivered to where it counts the most: your audience.

Ferrofluid cooling
Any technology that involves power also involves heat, and this can result in compromised performance if heat generation is not effectively controlled. The current driving a speaker generates heat in the voice coil that, in extreme cases, can cause the speaker to burn out. But even if the speaker doesn't actually burn out, that heat still results in inefficiency and non-linearity that degrade overall performance. As the power and heat increase, the resistance of the voice coil increases as well, causing power compression, a loss in acoustic out that reduces the system's dynamic range. This problem is overcome in the MSR250 by placing an cutting-edge ferrofluid in the voice coil gap, where it serves to conduct heat away from the voice coil with much greater efficiency than air. The results are smooth, natural frequency response and dynamics plus stable performance even under heavy use.

Excellent portable power
The MSR250 delivers the ideal blend of power, performance, features, and portability for an exceptionally wide range of jobs. A newly designed class D amp delivers 250 watts of clean, dynamic power via a high-performance 10" cone woofer and 1" titanium-dome compression driver that match up perfectly for smooth, uncolored response from 55Hz to 20kHz. The woofer has an oversized 2.5-inch aluminum voice coila size you'd normally see on a 15" woofer that contributes to outstanding sound and durability. With all this power and performance the big surprise is how light and manageable this cutting-edge powered speaker is.

Versatile two-channel In configuration
For extra In flexibility the MSR250 features dual input channels, each with it's own low and high equalizer controls and level control. The signals from the two inputs are mixed and delivered via the MSR250 speakers plus the rear-panel line out connector, allowing useful linking to other speakers or audio devices for simple system expansion. Input 1 has balanced XLR and phone jack connectors that accept microphone or line in, and input 2/3 is actually a mixing input in its own right with phone jack and two pin jack connectors.

Made for heavy-duty use
Although it's lightweight and simple to handle, the MSR250 is exceptionally durable and will take the tweakiest tours in stride. It's also designed to be used in a bunch of situations, including normal upright and wedge-style floor monitor operation. There's also a built-in pole-mount receptacle for useful stand mounting.
