Electro-Voice Sx300E - 12” Compact Passive Full Range System with RMD and 65° × 65° Coverage

The Electro-Voice SX300E is a passive 2-way full-range loudspeaker designed for professional PA applications in portable and fixed installation. Its trapezoidal enclosure is constructed of molded structural foam polypropylene (high-strength copolymer), a lightweight and rigid material that reduces unwanted vibrations. It incorporates RMD (Ring-Mode Decoupling) technology, applied to the enclosure and transducers to suppress resonance modes and improve intelligibility . The LF path uses a 12” DL12BFH woofer , while the HF path integrates a DH2010A compression driver with a 1.25” titanium diaphragm and a 65° × 65° constant directivity Varipath horn, providing uniform and stable off-axis coverage.

With a sensitivity of 99 dB (1 W/1 m) and a rated maximum level of 131 dB , the Sx300E delivers sufficient sound pressure for small and medium-sized events. Its frequency response (-10 dB) extends from 50 Hz to 20 kHz , with a crossover at 1.5 kHz . The system handles 300 W continuous ( 1200 W peak ) at 8 Ω (min. 5 Ω ). For everyday use, it provides dual Neutrik Speakon NL4 connectors , a 35 mm tripod shoe , and four integrated M8 x 1.25 threaded points for suspension or mounting with MB series hardware. Dimensions: 586 × 429 × 312 mm ; weight: 14.5 kg . Black finish.

Product benefits

• Enhanced intelligibility: RMD technology reduces acoustic and mechanical resonances, enhancing speech clarity and musical definition.
• Consistent Coverage: The 65° × 65° pattern maintains off-axis response, facilitating consistent mixes and fewer hot spots.
• Portability and robustness: lightweight and durable chassis with handle, designed for frequent assembly and disassembly.
• Mounting Versatility: Compatible with 35mm tripod and MB hardware for wall/ceiling or suspension with M8 inserts.
• Easy integration: dual Speakon NL4 in parallel for daisy-chain wiring and quick setups.

Use cases

• Main PA reinforcement or side-fill for corporate, educational, and religious events.
• Mobile band and DJ performances where a high SPL/weight ratio is required.
• Fixed installation in multipurpose rooms, gymnasiums or auditoriums, with flying options using M8 points.

Frequently Asked Questions

• Can the Sx300E be suspended? Yes. It has four M8 x 1.25 rigging inserts and is compatible with official hardware such as the MB100/MB200 , following the manufacturer's guidelines.
• Can it be used as a stage monitor? The trapezoidal enclosure allows for lateral use; optional F200 feet are available for added stability.
• Does it support standard tripod mounting? Yes, it includes a 35mm (1 3/8”) mount .
