OVERVIEW

A powerful sub with a modest footprint for crowded stages.

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.

    Comments about QSC KSub Powered Subwoofer:

    Subwoofer is easily transportable with nice Tight Bass...Kick Drum is punchy...Small enough to get into most Cars...We have all types of 18" Subs in our Sound Company but the KSub is a perfect size for many mid size venues without taking up alot of room...Two of these is a killer System.

      QSC Bass Rig!

      Comments about QSC KSub Powered Subwoofer:

      I purchased a level 3 "scratch 'n dent" KSub as the price was too good to pass up. It arrived in a sturdy non-factory box that held up well against the UPS distribution system and included the USA spec locking IEC power cable and threaded speaker pole (no manual or 240v power cable, not that I need either as QSC has PDFs available).

      As clearly disclosed in the photos, it has a few dents and paint chips, which I repaired with cyanoacrylic glue to harden the damaged wood and a black paint pen to touch up the missing paint. None of the damage compromises the structural integrity of the cabinet, and I also purchased the matching cover to prevent more from happening.

      While 74lbs. sounds like it would be heavy to move on your own (especially since I live upstairs in an apartment complex with no elevator), it is very manageable thanks to the 3" caster wheels and ergonomic aluminum handles. The ability to use it as a dolly for other gear also is a bonus with the Velrco strap on top of the cover (purchased separately). It's also small enough to store in a modestly sized closet when it's not in use, preventing the cover from becoming my cat's new favorite scratching post.

      That said, I primarily use the KSub in an atypical application: as a bass amp in conjunction with a QSC KW122 and an Aguilar Tone Hammer DI. It sounds excellent as part of a bass amp rig, and playing through a 2000 watt bi-amped setup always brings a grin to my face. Given that my "half a PA system turned into a bass amp" setup is meant to amplify a whole band, it's very loud, clear, and articulate as a monitor/amp. I chose this setup as I am also a guitarist and I use the KW122 with both acoustic and electric guitars, using a Fishman Platinum Pro DI for acoustic and a Tech 21 Blonde as my electric preamp. The KW122 works great on it's own for bass, but adding the KSub feels like going from a 1x12" combo amp to an 8x10" SVT rig. On top of that, it also can be used as... a PA system! Very convenient.

        I bought this product for live performance. I used it all week while rehearsing and for the live show and it went extremely well. The bass really kicks on this thing and I have only turned it up half way, with my mixer volume not all the way either. It is really nice.

          I never thought this Ksub would make my 2 k12's sound that much better. I want to buy another one.

            I own 2 and match them with 2 K12-s run them through a BBE 882i sonic maximizer ...the sound is un believable . you wont be disappointed !
            great low end with a endless amount of configuration settings
            Build quility um matched strong , and having heavy duty castors makes these extramely robust
            great for the money not cheep but great value when you buy the best you have to expect to pay a bit more

            Comments about QSC KSub Powered Subwoofer:

            I've owned these for about 6 months, and am very happy with them. I also had the hpr18's, and I actually prefer these better. Ended up selling the hpr's - I just stopped using them.The k-sub is a much more "musical" sub, and has plenty of tight punch for only being 12" drivers. They are very gigable- and have a small footprint.Sometimes I do miss standing in front of the hpr's to feel the wind blast- they do have their place- but if you're looking for quality low end, and want to save your back, then check these out.

            Big sound from a small footprint

            from chicago

            See all my reviews

            Comments about QSC KSub Powered Subwoofer:

            I have 2 of these. The speakers sound like a much bigger speaker. The bass they produce is a loud snappy type of bass. They are very portable and I can fit these in a car instead of a van or suv. I use them with a Driverack Px. I can somewhat taylor the kind of bass they play. I play them loud and it takes a lot of volume to make them clip. The speaker is designed to play dance, r&b, or just about any type of music. The only thing I noticed is that if you are playing real bass heavy music; such as hip hop. The speaker does not play very low hertz. It is designed to play down to 44hz. The spl the speaker puts out is 130db; which makes up for the deficiency in the amount of low frequency bass it produces. 2 twelve inch woofers playing together in a 4th order bandpass enclosure makes it sound almost like an 18 inch woofer; but not as low. Their are no powered subwoofers in the market that are this small that have 1000 watts that sound like these. The connections on the back let you connect just about anything. If you want to run a mic, a cd player, or even an ipod straight to the speaker without a mixer you can. The warranty also can't be matched; at 6 years. Also these are the same thickness birchwood cabinets as the kw series.
