KS118 Active 18" Subwoofer

The QSC KS118 is a beast of an 18-inch powered subwoofer, delivering chest-thumping bass down to 35Hz that’s ideal for weddings, parties, and larger gigs in my mobile DJ setup. Its 3,600W Class D amp drives massive SPL up to 136dB peak, pairing perfectly with QSC tops like my KC12s for full-range punch. Key Strengths • Deep extension in DEEP mode and cardioid array option (with 2+ units) rejects rear sound, keeping bass focused on the dance floor without stage bleed. • Built-in DSP with presets, gain control, and low-noise fan make setup simple for quick loads in Western NY venues up to 60 miles out. • Rugged plywood cabinet with casters (77 lbs) handles road abuse; M20 pole mount stacks easily with mains. Most Important to Know Omni or cardioid modes optimize for any space—cardioid shines for stage use. Runs clean even pushed hard, with musical lows that fill rooms effortlessly for all genres. What Other Customers Should Know Pros like DJs rave about its output-to-size ratio over older models; EQ right and it thumps without distortion.

Love this Sub. Great sound and response. Powerful

I bought 2 of these before the TARRIFFS. Now they are$500 more everywhere.... these are Great subs for djs.

The sub as shown in the pics came damaged. The power led is somewhere in the back of the sub also shown in pics. Do not buy this on amazon. Go at it local store, open it, try it, verify that everything is as it should be.

This is an excellent unit for my mobile wedding / pub gigs. There are products that go 'lower' or go 'louder' but this thing delivers excellent punchy bass that fills the room day-in and day-out at a great price. Combine it with a screw-in type crank-handle speaker pole and you have a solid base for even the biggest tops. Pairs great with my 68lb SRX812's. The included built-in casters are quiet and strong. Don't forget to order the factory cover to keep your investment safe!

Is this sub slightly over price, Yep!! Is it worth the money especially if your a moble Dj, Yep!! Does this sub hit hard and sounds impressive, abso-fu@king-lutely!! (check out what most clubs use) Is it a solidly build unit, Yep!! Are there better subs out there, Yep!! Would I buy a second one, yep already did.

Sub itself was good shipment not so much it arrived damaged.

Had this for a week and a half now and love it sounds great and was shipped with care and discretion. Arrived ahead of time. Put it in my home and haven’t even run it very hard yet but being an 18” is it’s very impressive. I bet my neighbors hate me now!!!

Definitivamente QSC tienen más poder que HK que ofrece en su linear 7 k118 (2000 whats) y QSC ofrece 3600 whats y además tienen mucha fidelidad... tengo todo mi equipo de audio en QSC, desde la consola digital de 30 canales hasta bocinas. Los prefiero sobre muchas marcas, claro cuestan más pero si quieres sonar con calidad y fidelidad lo valen. Actualmente tengo 12 ks118 y 14 k12.2.. Me sirven para grupos chicos y grandes.. Acá dejo un souncheck con Consola digital touchmix 30. Nota: en Este 2025 compre una SQ6 Allen and Heath y suena este audio QSC eapectacular.

QSC KS118 Best Sub in the Market. Very Punchy and Deep Bass Best of the Best 3600w

Great product, just took a long time for delivery,

Love this sub it is small in size and it is very loud. I got two of them

It gave my drum set a fuller low end bass! 😊
