About Delivery

QSC KSUB Dual 12" 1000W Active Subwoofer

The QSC KSub sets a new standard in subwoofers. Fantastic sound quality, high powered and, considering it's a sub, fairly light weight. Utilising Class D power modules with DSP processing, the KSub will deliver consistent lows at every use.

The QSC KSub uses a birch cabinet in a dual 12" bandpass design and even includes low noise casters to make transportation easier. There's also a threaded pole socket for easy and secure mounting of top boxes.

The KSub's versatility extends to offering combo XLR and 1/4" TRS jack inputs that will accespt both Mic and Line level signals. Three audio sources can be mixed internally and then summed to a balanced output that will allow you to daisy chain to another unit. QSC have even included direct outputs for each channel for even more flexibility.

The QSC KSub comes with a 3 year warranty as standard. This can be upgraded to 6 years if you register your product within 30 days of purchase at
