QSC

Description

The QSC KSub Powered Subwoofer is the ideal supplement to QSC K Series 2-way speakers for live reinforcement of bass instruments and drums, or higher-level playback of recorded music. Its 1000W Class-D power module never fails to deliver. The KSub subwoofer's M20 threaded pole socket (pole included) provides a secure, wobble-free method of elevating a mid-high speaker over the subwoofer. The KSub subwoofer's compact footprint won't take over the stage, dance floor, or seating area of smaller venues. A pair of high-power 12" speakers in an optimized band-pass enclosure will handle everything the 1,000-watt power module can give them. Compact in size, the QSC KSub has ergonomically designed handles and 3" noise-free casters ease load-in and load-out.

AMAZING POWER!

1000 Watts is really loud. The bass from the KSUB sounds smooth and clear, with deep solid chest thumping hits. The dual 12" speakers inside really are amazing in how QSC managed to produce the powerful bass this sub gives. I bought this KSUB new from my local GC and in the pictures the casters are silver, but the cab i bought had BLK casters and they didn't rattle either when i tested the sub. I went straight home and set it up and was amazed. 18 inch subs produce a low frequency of 30 Hz, and this sub produces as low as 44 Hz. But 12's are punchier than 18's. The payoff for me in this sub is the full sounding bass of the KSUB and that it's light enough for me to lift and load alone. If you get an 18 in favor of a deeper 30 Hz bass, you'll definitely sacrifice the lightness and need a second person to help you lift it. PROS: It's very light (72 lbs.), it's compact, it sounds great, looks very professional, quality craftsmanship. I'm 100% satisfied. CONS: seriously no downside to this sub.

Grear for DJ's. Not for Bands.

I bought one of these subs along with two k12's from my local guitar center. My overal first impressions of this sub was that it sounded good but didn't really have the output or the bottom end that I was expecting. So I bought another. 2 ksubs with the k12's mounted on top sounded great. I have used these for both DJ gigs and running sound for my Dad's band. After having these for about 6 months I finally decided that I wanted more and sold both of them and bought a KW181. Big difference. I can't wait to get another. The ksub's just simply don't have that impact that I was looking for. If your looking for chest thumping bass and you like QSC buy a KW181.

    This thing added some serious punch to my set-up. Currently I own 2 JBL EON 515's and adding the KSub gave it a real boost. Cranked it up and 2 of my picture frames fell off the wall. I'm very impressed with it's size, portability and above all sound. And yes, it fit perfectly under my table. Can't wait to use it at my next event. Already making plans to buy another one.

  • Great Sounding sub woofer

    I already had one K Sub with dual 12" speakers and added another for a full stereo sound on stage. These subs are really powerful and clean sounding.

  • A must!!

    I use two of these, with k8 speakers for each channel. The sound is so clear and un-colored, it's like listening to a good set of headphones anywhere you are in a 600 swift room!

  • Super awesome speaker I'm glad I finally got a pair of them

    I wanted a sub that sounded great and was/is compact - I own Qsc KW181 and sometimes there isn't enough space - now I can fit more stuff in my car so I can offer a client more services without breaking out a trailer
