Electro-Voice ETX-18SP 18" Powered PA Subwoofer 1800W
When it comes to low frequency response, bigger speakers generally perform better, and this is exactly what the Electro-Voice ETX-18SP offers, an 18" woofer paired with a 1,800W Class D amplifier with a maximum SPL of 135dB.
To better manage this powerful sub, Electro-Voice equipped the ETX-18SP with "QuickSmart" DSP, which optimizes sound quality and allows for different presets for different applications.
Finally, it comes with blower-controlled thermal management, that protects internal components from heat damage.
