The MSR800W powered subwoofer makes adding chest-pounding bass easy. With 800 watts of power, the crowd will hear AND feel the low end! The long-travel 15’’ driver provides high SPLs while maintaining low distortion for tight, punchy sound. The cool running internal amplifier includes an active crossover to easily route the high frequency signal out to the main speakers. The low profile bass reflex design makes placement and transport easy.

Great PA Sound Has Never Been Easier Or Better Looking
Much of the work in putting together a high-performance sound system involves amplifier and speaker selection and setup. Here are a pair of solutions that can take you directly to great sound without the usual complications. The MSR400 powered speaker can be used alone or in combination with the MSR800W powered subwoofer to assemble sound reinforcement systems from modest to massive. They look great, too. So good, in fact, that they can be used as-is in many permanent installations without requiring any cosmetic cover-up. And, of course, theyre more than rugged enough for demanding tour applications as well.
 
The Case For Built-in Power
Whether for use on the road or in permanent installations, powered speakers offer numerous advantages over their separate counterparts. The most obvious is that you dont need separate external amplifiers or the extra connections required you can plug your mixers outputs directly into the speaker inputs. In a modest-size system this alone can eliminate an entire rack of amplifiers. But there are sonic advantages as well. Optimum matching of amplifiers and speakers involves much more than simple impedance figures, and can be a formidable engineering task given the vast number of choices available. In the Yamaha MSR400 and MSR800W the internal amplifiers have been ideally mated to their respective speakers in every way possible, delivering reproduction quality that only such stringent matching can achieve.
 
MSR 400
 
Bi-Amplification
The MSR400 is a bi-amplified 2-way system, featuring 400 watts maximum burst power that drives the 12" cone woofer and 1.75" V.C. compression driver. Frequency division is accomplished prior to the power amplifiers via a line-level electronic crossover. This eliminates the problems with loss, distortion, and phase that are virtually unavoidable in conventional passive crossover networks. Another advantage of this type of system is that power can be optimally assigned to the low-frequency and high-frequency units for optimum efficiency as well as smooth, natural balance across the entire audio spectrum.
 
Wide Input Range & EQ Control
The MSR400 accepts nominal input levels ranging from 36 dB to +4 dB, meaning that you can directly connect any source from microphones to professional line-level gear. Three parallel-connected connectors are provided two balanced XLR-type connectors and one balanced phone jack that can be used as either inputs or parallel outputs. The MSR400 also features an input level control for matching with the source signal. Low and high EQ controls can be used to adjust the respective bands over a plus-or-minus 3dB range.
 
Versatile Placement
Speaker placement is as much a performance issue as it is a convenience and aesthetic issue. Proper placement will give you optimum sound as well as coverage while being as unobtrusive as possible. Of course, the more options you have the better. The MSR400 can be stacked or pole-mounted (theres even a pole-mount hole provided on the companion MSR800W Powered Woofer). And its flyable so you can benefit from the unrivalled coverage and positioning precision that only ceiling suspension can provide.
 
MSR 800W
 
For Sound You Can Feel
The MSR800W powered subwoofer is the perfect companion for the MSR400, extending the low end and completing the musical spectrum for maximum punch and impact. The high-quality birch plywood bass-reflex cabinet houses a 15 cone woofer powered by an ultra-efficient burst 800 watts amplifier, a configuration that can deliver the elusive 40 Hz through 120 Hz frequency range with precision and authority. Two balanced XLR connectors are provided for connection to the source, and that same signal can be directly passed on to the main speakers via a pair of XLR THRU outputs. Alternatively, the main speakers can be fed by the MSR800Ws dual HIGH PASS outputs, high-pass filtered at 80 Hz through100 Hz, depending on the setting of the cutoff frequency control, with a steep 18 dB/octave cutoff slope.
 
Visual Clip Indication
Both the MSR400 and MSR800W feature LED power indicators as well as clip indicators that warn of impending clipping. This allows the engineer to make appropriate adjustments to the source level.
