About the Electrovoice SX Series
The Electrovoice SX Series is a family of 12-inch passive loudspeaker enclosures designed for compact, portable sound reinforcement across live sound, DJ, speech, AV, and institutional use, as well as larger arrays in club and performance venues. Models share a 1.25-inch DH3/2010A titanium HF compression driver and a 65-degree by 65-degree constant-directivity Varipath horn, with Ring-Mode Decoupling (RMD) for improved intelligibility. Power handling varies by model, reaching up to 300 W continuous and 1200 W peak. The Sx300PI adds weather-resistance and, in PIX form, a multi-tap transformer for 70 V or 100 V distributed audio systems. Enclosures feature trapezoidal polypropylene or copolymer construction with integral handles, pole mounts, and rubber feet for stacking, and connectivity via Neutrik Speakon or Phoenix connectors depending on variant.
Electrovoice SX Series — buyer FAQs
What is the Electrovoice SX Series and what applications is it designed for?
The Electrovoice SX Series is a family of 12-inch passive loudspeaker enclosures built for compact, portable sound reinforcement. The range covers live sound, DJ, speech, AV, and institutional use at the smaller end, scaling to club sound, pro music, and performance and sports venues when used in arrays. Trapezoidal enclosures, integral pole mounts, and rubber stacking feet make the cabinets practical across all these settings.
How do the different SX Series models compare in power handling and connectivity?
Power handling varies across the range. The Sx100+ handles 200 W continuous and 800 W peak, while the Sx300E and Sx300PI both reach 300 W continuous and 1200 W peak. The Sx300E uses dual Neutrik Speakon connectors for easy daisy-chaining; the Sx300PI uses a single Neutrik Speakon, and the PIX variant switches to Phoenix connectors to support its 70 V or 100 V distributed audio transformer.
Which SX Series model suits fixed installation or outdoor use?
The Sx300PI is the installation-oriented variant, offering enhanced weather-resistance compared to the standard Sx300. The PIX version adds a multi-tap transformer for 70 V or 100 V distributed audio systems, making it suitable for permanent installations where constant-voltage distribution is used. All Sx300-series models can be deployed alone or combined in arrays, and the enclosure includes rubber feet with mating sockets for stable stacking.
Who makes the SX Series and where does it sit in their product line?
The SX Series is made by Electro-Voice (EV), an American professional audio manufacturer with a history stretching back to 1927. EV produces microphones, loudspeakers, amplifiers, and signal processing for sound reinforcement and commercial installation. The SX Series represents EV's compact passive loudspeaker offering, covering portable and installed applications within a single coherent family of enclosures sharing common driver and horn technology.
What should I check when buying a used Electrovoice SX Series loudspeaker?
Confirm which specific variant you are buying, as power handling, connectors, and weather-resistance differ between models. Check that the titanium HF compression driver and woofer are undamaged, that Speakon or Phoenix connectors are intact, and that any integral handles, pole mount socket, and stacking feet are in working order.
