QSC KSUB Powered Subwoofer

Fullrange models are housed in rugged ABS enclosures with a professional appearance that is at home in any application. ABS is a far more robust material than conventional speaker plastics and offers an additional measure of sonic clarity due to its internal rigidity. Ergonomic aluminum handles and a highly protective steel grille complete the package for ease of transport and long term durability.

The K Series fullrange models feature a unique Tilt-Direct™ pole cup mounting system. A simple turn of the dial engages a 7.5 degree downward tilt of the speaker allowing acoustic energy to be kept on the audience and off reflective surfaces for applications where maximum coverage from a high-positioned speaker is desired. Integrated M10 suspension points allow for suspended applications with a K SERIES M10 KIT (sold separately) or Yoke bracket (sold separately).

The KSub is a dual-12" bandpass design, constructed of premium birch and includes high-quality, low-noise casters. The subwoofer features a threaded pole receptacle for a positive, wobble free connection to a threaded speaker pole (included).

Remote gain control capability is offered via a potentiometer (not included) connected to the on-board Euroblock connector. In an installed application, multiple K Series speakers can be "daisy-chained" for total gain control from a single remote pot. Auto-standby mode is engaged after 5 minutes of inactivity.

Extensive DSP

  • DMT™ (Directivity Matched Transition) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural "dead" or "hot" frequency zones.
  • Intrinsic Correction™, first featured in our high-end line-array products maps 65-75 spacially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat bandpass target. The result is a speaker that behaves equally well across the entire sound field.
  • DEEP™ and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies.
  • GuardRail™ protection, first introduced on our GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping.

Features:

  • Lightweight portable powered speakers with legendary QSC amplifier power and reliability
  • 1000 watt Class D power modules in all models
  • Extensive DSP enhances system performance
  • Attractive and professional appearance
  • Rugged ABS enclosures (K8, K10 and K12)
  • Tour-grade 18 gauge steel grilles
  • Ergonomic handles with comfortable, non-slip grip
  • 35 mm pole sockets with Tilt-Direct™ (fullrange models)
  • M10 rigging points for suspended installation (fullrange models)
  • K10 and K12 perform as main PA or stage monitors

Connectors:

Balanced female XLR 1/4" line/mic level input, Balanced female XLR/¼" line level input, Dual Balanced male XLR full range line level out , Balanced male XLR "mix" out, Stereo RCA line level input, Remote gain control, Locking IEC power connector

      Comments about QSC KSUB Compact Powered PA Subwoofer 1000W:

      This could be a good Powered Sub...However, when the sqaure footage coverage or people/crowd increases....you lose bass response and can get muffly if you push to hard. I also heard a band use these and it was a very good fit. They had two tops and two of these bottoms for an audience of 220. So overall, these subs could be a good fit but not for a big room.

        Comments about QSC KSUB Compact Powered PA Subwoofer 1000W:

        I put this product to use at a military ball inside one of the Hyatt Regency's Ballrooms this past weekend and I was very impressed with its performance! The room had about 180-200 people in it but could have easily fit 250. I used 2 K12's with 2 Ksubs for this event but really didn't need both subs. I also was able to fit all my equipment in my 2 door Infiniti G37!! I didn't need any help as everything was light enough for me to carry. Upload took about 15 min and setup took about 15-20 min. Im so happy with this purchase and would recommend this to anyone!

        Comments about QSC KSUB Compact Powered PA Subwoofer 1000W:

        I bought one of these KSubs to go with a pair of K12's. The K12's sound so much better than any other powered 2-way speaker that I guess I got my hopes up that the KSUB would beat any other powered subwoofer as well. I was sadly mistaken. This subwoofer hits its limit way to easily and you can barely tell it's even working when paired with the K-12s at reasonable volume and switched to Ext. Sub. I'm very tech savvy, but since I was so disappointed, I actually called tech support to see if I was setting something up incorrectly. Nope, it was all correct. So, long story short, if you are using these with the K12, you will need one KSUB per K12. Don't skimp out like me and only get 1 KSUB for both K12's, you will be equally disappointed with your $1,100 purchase.

          i gotta say the QSC K series kicks
          i have two k 12s which are amazing so i decided to buy two ksubs to compliment the speakers and dont get me wrong they sound great but they peak much easier the the speakers so i was expecting a lil more bang for the buck
          this are one of the most expensive subs but are they the best probably not i think QSC should have came out with a k15 and done one 15inch powered sub and put a cross over of 80 and less

            Fantastic sub! I sold my HPR 181i in favor of this. This has is only 77lbs, but the dual 12' speakers shake dance floors. No kidding. One is good enough for parties up to 200-250. Buy two for larger events. I am sold on them.

            I just bought this sub and I am so glad I did. I used it the next two days in a row after purchasing it and I have been getting nothing but compliments and praise about the great sound from party goers and fellow DJ's, Musicians and Audio Engineers.

            QSC has out done themselves with this K series. I have only purchased the sub so far but I will be buying another one as well as the k12 to match.

            Lightweight and powerful speakers deliver the sound you will be looking for. If you haven't gone out to take a listen to these, you are really missing out on the latest and greatest speakers on the market.

            Perfect for DJ's & Live Applications for small to medium sized rooms.

                    No, the cover is sold seperately; however, I was able to talk the salesperson into including the cover in my package for free. I ordered several thousand dollars worth of gear, so I think it was pretty easy for them to still make a profit while meeting my needs.
