Very Cool


What a cool product. Very easy to set up and use. Durable and heavy duty. Great sound and a great price. "This is a real hands on product review from [email protected] Sam Ash KOP"



Considered one of the best in its class


One of the newest additions to the Electro-Voice range of truly high-end PA speakers, the EKX-18SP is a force to be reckoned with. This 18" powered subwoofer pushes out an astronomical 1.3kW of power for a 134 dB peak SPL down to 35 Hz. The reason why the EKX-18SP can provide such amazing performance is how each component was meticulously engineered by EV. The latest technology such as the SST waveguide and next-generation transducers are incorporated into its design, meaning you get the best experience possible from your investment - it sounds great and never lets you down. The rugged wood enclosure and high-grade build quality means the cabinet looks great and can withstand the rigours of the road. this is a hands on review from Jeremy at Sam Ash Music
