Gearank Recommendation

The ETX-18SP appeared on our recommended list for PA Subwoofers for 2 editions from October 2020 until October 2022 when it was out-ranked by the Electro-Voice EKX-18SP, QSC KS118 and JBL SRX828SP.


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.
