        Comments about QSC KSub - Dual 12" 1000 Watt Active Subwoofer for K Series Speakers:

        I bought the KSubs for use with K Series speakers to complete my compact system. If you are looking for earth shaking bass then the KSub is not for you, although they come pretty close for dual 12" drivers. Set up right, coupled together the KSubs are awesome. The bass is warm, tight and punchy. Perfect for a 100 to 250 person event. You can even do outdoor events as long as you don't expect to shake the foundation. Subwoofers are very important in any system to provide a full bodied sound. I use a sub for every event, it provides better coverage and fuller sound than just using two full range speakers. It lets your speakers operate more efficiently without having to push them too hard. Your subs control all the bass and you control how much and how loud you want them. They really shine when you use them with a DBX DriveRack PX. Highly Recommended for any DJ or Musician looking to add punch, presence, bass extension and/or improve their overall sound.

            Outstanding Build Quality. Amazing how much bass you can generate from 2x12" speakers when the cabinet design is right! :)

            Perfect dimensions to fit in the back seat of my car!

            I own a lounge downtown and went through dozens of self power subs. This one kicks booty! With the constant wear and tear this thing goes through it still packs a super punch.

              Powerfull, light weight, attractive, this sub has it all. I run these with 2 Yamaha MSR400's and man they sound great. 2 enclosed 12's mean two things for me, lighter and tighter. The 18's had too much sustain for while the K-Sub gives you that tight kick without all the extra noise you dont need. I use mine for DJ'ing and live gigs and man this is perfect. I plan to get another to complete my monster.
