It’s All About That BASS

June 21, 2016 by Scott Jarema

Yamaha is one of those companies that does many things well. From motorcycles to musical instruments, they also produce some of the best outboard boat motors made. I have one on my pioneerbunn-jeremaBoston Whaler, but I digress.

The Yamaha DXS18 is the flagship subwoofer in their DXS subwoofer lineup. It is an active subwoofer with an 18” cone sporting a 4” voice coil magnet at its heart. Featuring a band-pass enclosure and a class D amp driving it, with 1020 watts of dynamic power, (800 continuous), the sub can realize 136 dB maximum SPL, (sound pressure level) and a low end down to 32 Hz. Weighing in at a hefty 110 lbs, the DXS18 is all business. Yamaha offers an optional wheel kit, (SPW-1) which makes it easier to move it around, and I highly recommend this option for mobile DJs!

Un-boxing the DXS18, it came packaged with a power cord and owner’s documentation. I was pleased with the solid construction (which I’ve come to expect from all of Yamaha’s different kinds of products). The dense plywood cabinet was finished in their “LineX’ textured black coating, which makes for a durable finish that will take a beating gig after gig. With integrat- ed handles on both sides, it felt solidly built and certainly looked like a professional piece of kit.

I was eager to put it through its paces, so I dusted off my trusty JBL EON 515XT active cabinets for the test and proceeded to work. Set up is fairly straight forward and the DXS18 comes with two recessed mounting sockets to accommodate a speaker pole for your PA cabinets. One is a standard 35mm diameter and one is threaded for M20 screws. In back, you will find two pairs of balanced XLR female and male jacks for your inputs and outputs respectively. Plug your left and right channels from your mixer into the inputs, then plug your left and right speakers into the outputs, and you’re ready to go. If you are running two DXS18s, you can run your left channel to one and your right channel to the other’s inputs and connect your speakers to the corresponding outputs. In this configuration, you can use either left or right channels.
