Designed to deliver stellar audio performance and versatility for intensive audio applications, the RCF NX 915-SMA 15" 2100W Powered Stage Monitor Speakeris a highly flexible, easy-to-use, 2100W powered stage monitor speaker for today's working musicians, singer/songwriters, mobile DJs, and other sound providers. The speaker is perfectly tailored for horizontal or vertical deployment, allowing it to be used on a speaker pole as a main PA for smaller applications.

The highly efficient Class-D bi-amplifier delivers 1400W peak to the 15" woofer and 2800W peak to the 1.0" titanium/neodymium compression driver, which provide full-range audio (45 Hz to 20 kHz) with a sound pressure level powerful enough to ensure you can hear yourself onstage. The NX 915-SMA utilizes RCF's proprietary FiRPHASE and Bass Motion Control DSP processing to deliver absolute clarity and deep, powerful bass response. The tour-ready, rugged all-wood cabinet is easy to carry and secure to install on a pole. The NX 915-SMA includes a power cord.

• The most powerful amplifier in its class. RCF's improvements in transducer design make them stronger and powerful, so the amplifier follows the evolution. With 2100W power, the 2-channel NX 9 Class-D amplifier is 50% more powerful than previous models, able to manage extreme sound pressure levels with an ultrafast attack, realistic transient response, and very low heat loss.
• NX 9 is energy efficient, so there's no need for a cooling fan. The amplifier is attached to a solid aluminum heat exchanger in the rear of the cabinet - with no moving parts. The input circuit features a new low distortion design with an advanced safety limiter, maintaining the true character of the input signal at all levels. All NX 9 amplifiers are designed according to EN62368-1 for maximum safety and present a Switch Mode Power Supply section joining high-efficiency with minimum weight.

Lightweight and powerful, RCF drivers are a reference in high performance. All transducers are designed by RCF engineers in Italy for maximum reliability and perfectly matched components. The new 1.75" voice-coil design with Polyimide-Kapton dome features a new bonding technology and reinforcement ribs making it 10 times more rigid than previous models, for increased accuracy and durability. The redesigned phase plug increases sound clarity with less distortion. Low-frequency transducer design gains more stability over higher currents, with less distortion and better heat handling.

• When searching for an extended bass with enhanced performance, RCF engineers found a way to remove the high-pass filter, replacing it with a forward-thinking approach. Introducing BMC (Bass Motion Control), the newly advanced woofer excursion management feature. The speaker equipped with BMC can handle the lowest audible frequencies without affecting the woofer stability, with extended linearity and better sound integrity.
• The BMC method works by creating a complete map of the dynamic behavior of the woofer, to generate a custom algorithm that only limits overexcursions. This gives total freedom of signal reproduction to the transducer. When high-pass filters normally protect the woofer motion from becoming destructive but change the phase behavior, the new BMC algorithm breaks conventional rules.

RCF speakers are designed using a proprietary and advanced digital FiR technology, conceived to deliver transparent sound, absolute clarity, and perfect imaging to the listener. Special FiRPHASE filters allow for coherent distribution of sound for all listeners without phase distortions, ensuring minimum latencies in the system.

The new True Resistive Waveguide is the result of several refinements in both the transducers' and the vented ports' design with Finite Element Analysis, and constant measurement in RCF anechoic chambers. Thanks to FiRPHASE technology, the new shape, and the placement of the ports, the speaker now acts as a single ideal source for a perfect sound image. Acoustically, the TRW waveguide mimics a resonance-free pure resistive load reducing the high-frequency distortion of a classic horn. The coverage angle of the waveguide provides constant directivity to the entire listening area and improves stereo panorama.

NX 9 can operate as either the main system or as a floor monitor. This flexibility makes it a smart choice for a wide range of live sound applications. The rugged all-wood cabinet is easy to carry. The lower side includes a steel pole socket for mounting on a stand or a subwoofer pole. From the wood cabinet to the final texture and the rugged protective grille, NX 9 offers maximum strength for intensive use on the road and can be used for fixed installation.

Thanks to the TWR waveguide and the pole mount socket on one side, NX 915-SMA can be used as a powerful main speaker, mounted on a stand, or paired with a subwoofer.

• NX 915-SMA active stage monitors perfectly complement your multi-effect / amp modeler. FRFR stands for Full Range Flat Response, which means you can model your sound through a remarkably neutral speaker. With 4200W peak flat frequency and 0° phase response, your NX speaker can serve as both your guitar/bass cabinet and your stage monitor.
• Traditional electric guitar cabinets have their characteristic timbre, and this can be a bottleneck when you deal with multiple modern guitar effects and different guitar sounds especially onstage. Your guitar sound can be adapted and changed to your taste using a neutral and analytic speaker, with complete freedom and all the power you need to rock the stage.

The highly innovative entertainment industry is always evolving by increasing demands on interconnection systems. Particular environmentally sealed connectors are highly requested for heavy-duty and harsh environment applications of entertainment equipment. The speaker features True Outdoor Protection (TOP) PowerCON TRUE1 power input connectors. These ruggedized sealed connectors feature IP protection and UV resistance approved according to UL50E.

The NX 9 Series is designed to fit all listening requirements from sound providers to deliver high power and pristine sound from a compact and portable speaker, with an integrated amplifier onboard. From the wood cabinet to the final texture and the rugged protective grille, NX 9-SMA offers maximum strength for intensive use on the road.

Q: 3. Do they expand/extend to the sides? How much?

A: This device does not expand or extend.

Q: 4. how do you adapt this stand to accept clamps?

A: Our speakers just have the pole socket not sure how you would use clamps.

Q: 5. Does the monitor have a standard VESA mounton the back so it can be used with other teleprompter stands?

A: Since this is designed for use with teleprompters, there are no VESA mounting pattern holes on the rear of this monitor.

Q: 6. Will this work with Mackie Thump 15 ?

A: I think these are a little light for that size and weight and of course the Sub 15 goes on the floor

Q: 7. Can this speaker be used while horizontal?

A: Yes, these can be oriented in a horizontal position. If using the supplied wall mounts you will use the attachment points on the side of the speaker.

Q: 8. If i hook up a pair of these to my tv will the tv remote control the volume or do i have to use the volume control on the speaker itself?

A: Whether the volume of the Yamaha MS101-4 Powered Monitor Speaker 30W Class-D could be affected by the connected TV audio output source would depend on the functionality of the specific TV connected. Presumably the output on the TV is fixed and control over the MS101-4 would be adjusted via the onboard volume pots.

Q: 9. Can a 2nd speaker be connected for stereo?

A: Not directly, no. You can add a second MS101-4 Powered Monitor to allow for a stereo setup, but the second monitor can't receive the corresponding signal via the first MS101-4. If you are sending the left channel to the first one, you can only send the same channel to a second speaker via the line-out XLR port. You will still need to wire the second speaker to the main device you are using to send a stereo signal to the speakers.

Q: 10. How do you temporarily turn off the solar powered part to my speaker is this one?

A: The solar-powered charger for the Humvee Portable Solar-Powered Wireless Speaker with LED Light cannot be turned off.
