A lightweight high-power 300-watt, 12-watt peak, state-of-the-art speaker.

The Sx300E, with 300-watt continuous-and 1,200-watt peak-power handling, is among the world's best lightweight, high-power speaker systems.

The Electro-Voice Sx300 is a two-way, high-efficiency, constant-directivity compact speaker system. The Sx300E delivers over 125 dB continuous with 131 dB peaks (one-watt/one-meter) at full power. The high-frequency section of the Sx300 utilizes a molded-in, 65 x 65 constant-directivity horn. This unique pattern contributes to high intelligibility, vocals sound natural while they sonically cut through in reverberant, noisy rooms. In addition, the coverage pattern is unusually uniform over its range of operation. Sound quality off axis is very well maintained, even at 45 off axis (a 90 total coverage angle), beyond the rated coverage angle. The horn's unique, Varipath throat geometry also helps direct driver output to the corners of the room. This helps cover areas of the audience that typically do not receive good coverage.

The Sx300E delivers better pattern control and projection than typical 90 horns, and features proven and reliable EV components, including a DL12BFH cast-frame, 12" woofer and DH2010a pure titanium compression driver. With Ring-Mode Decoupling, it delivers accurate vocals, instruments, and mids. The Sx300E's rugged, durable, polypropylene enclosure is lightweight and sturdy. Its built-in stand-mount and inserts on the enclosure allow the system to be safely suspended and arrayed using a wide range of optional, cost-effective hardware. The Sx300E can also be used as a floor monitor with F200 attachment, and parallel Neutrik Speakon input connectors for safe, loss-free connections.

High-impact polypropylene structural foam provides a stiff and extremely durable lightweight enclosure. Molded into the cabinet are an integral carrying handle and a stand socket for mounting on 1-3/8" stands. Systems can readily stacked using the rubber feet that are attached to the bottom of the cabinet and mating sockets that are molded into the top. The trapezoidal-shaped cabinet, in combination with the uniform 65 x 65 directivity characteristics, make the Sx300 ideal for use alone or in arrays.

Through the extensive use of computer-aided design and modeling, Electro-Voice engineers have developed the Sx300E as a state-of-the-art professional loudspeaker system.

Comments about Electro-Voice SX300E 12" 300W Passive PA Speaker:

What can I say, except that if you have the money for these as mains or as monitors, you wont be disappointed. I use 3 of these as monitors with the F200 feet and they cut thru just fine. As mains I would use subs (EvSb122) and cross them over around 100hz. Killer compact system that can be used by duo's, trio's, bands, DJ's, schools, or any other application needed to get the voice projected. I bought mine used but wouldn't think twice to buy new ones if I needed/wanted more of these. I'm also using 1 Sx300 sitting on top of an EvSb122 as my keyboard stage set up. The vertical hgt is perfect for the Sx300 to shine thru the stage mix with little to no effort. I drive them with a QSC PLX1804 at 4 ohms w/o a cross over. Being able to handle 300 watts RMS continuous (each) should do fine in almost any application short of an arena.

    Comments about Electro-Voice SX300E 12" 300W Passive PA Speaker:

    I bought a pair of EV SX300's for our band's sound system based on the others' recommendations and studying the specs on these speakers. I needed something light yet powerful. These were perfect. They sound clean and crisp with just enough bottom. I have had these for about 15 months. I used a pair of these in conjunction with the SB2A and SX122SB for a music and wine fest with an outdoor audience of 500-1000 people and was blown away by the sound and volume. They are more expensive but well worth the money!

    I'm impressed

    Comments about Electro-Voice SX300E 12" 300W Passive PA Speaker:

    I am impressed. I would definitely consider getting these for myself for band purposes. Asubs would be needed for that low end thump ... But for most gigs, these would work fine.
    These speakers are replacing Yamaha S115V. They were installed at my school in our auditorium ( I'm a teacher ... Also in charge of running sound for events). I was originally concern these speakers wouldn't have enough bottom end ... I was wrong. The EV speakers provide more clarity with plenty of bottom end. We use the for School dances, visiting musicians solos, up to 4 piece rock/blues band -- so far they have been great.
    Very clear sound ... Great for the money.
    Good bang for the buck.
