Big bottom if you don't already got 'em.

No matter what kind of music you play, a subwoofer will add a warmth and depth of presence that you and your audience will find engaging, pleasing, and even intoxicating. "But I play in an acoustic band," you say. A lot of the charm and character of an acoustic guitar signal resides in some surprisingly low frequencies. The fundamental frequency of an E string is 82 Hz, and the A is 110 Hz. The EV ETX-18SP is an 18" powered subwoofer with 1800 watts of Class-D power with 135 dB peak SPL. It reproduces frequencies from 28 Hz to 180 Hz, so whether you are adding depth and warmth to vocals and acoustic guitars in an Americana setting or DJing dubstep and drum and bass in a dance club, the ETX-18SP will add a new dimension to your performance.

Inside each low-profile, tour-grade wood enclosure are a range of unique new features that set ETX Powered Loudspeakers apart, combining intelligent technology and innovative industrial design for spectacular results across all applications. EV-engineered high-efficiency transducers and high-powered Class-D amplifiers, Signal Synchronized Transducers (SST) waveguide design and smart FIR-Drive DSP all work together to provide peerless EV sound quality and precise coverage at the highest SPLs.

  • 1800 W Class-D power amplifier with integrated FIR-Drive DSP
  • 135 dB peak SPL

Comments about Electro-Voice ETX-18SP 18" Powered Subwoofer:

I am using one of these in my mobile dj setup along with a pair of jbl prx712 top cabinets and it keeps up very well. Last weekend did a wedding with about 200-250 on the dance floor in an outdoor venue under a tent and everything was loud and clear. The bass for just one sub is impressive. I did turn down the eq at 30hz to get a little more output. Every other wedding I have done I have had plenty of output and can't believe how much really low bass this thing cranks out.

Comments about Electro-Voice ETX-18SP 18" Powered Subwoofer:

The sound quality on this product is great. It can hit lower than the qsc kw181 and sounds great, however it's not powerful at all. The qsc kw181 which is cheaper can push out more chest thumping sound with ease while the etx-18sp peaks and limits and turns itself down with the "Auto-Temp" feature. It's fanless and the subwoofer overheats continuously. The JBL srx828sp is fanless and it never has this problem.

If you care about live performance sound quality, then by all means get these subs, but I have a pair of etx-35p and two etx-18p is too weak to be paired with them. Two qsc kw181 however is mind blowing with it and the quality is more than adequate for live band performances. EV is good for sound quality, but don't expect any of their subs to actually provide power. If you're a DJ consider getting the cheaper kw181 which is worlds better than this subwoofer.

Here are some of my tests.
Feed KW181 and etx-18p the same signal. 0db for both, etx-18p peaks and temps immediately in LIVE mode. QSC can go to +5db without peaking, etx-18sp has to go to -15db to stop peaking.
