QSC K Cardioid Subwoofer - Keep Bass in Its Place

QSC Cardioid sub

Every now and then a product is released that makes you think “why hasn’t this been done before?”. The new QSC K Cardioid Subwoofer is one of those products. It is a first-in-class single-box cardioid subwoofer that is portable and affordable.

The problem with most subwoofers is that they radiate LF in all directions, meaning that there is a lote of wastage, and clarity can often be jeopardised. The more savvy engineers out there have devised ways of achieving a cardioid-like dispersion through various means but there is not a ‘out of the box’ solution that matches the QSC K Cardioid Subwoofer.

Powered by a 1,000 Watt Class D amplifier with DSP technology, and featuring dual 12-inch long excursion drivers, each arranged in a 6th order bandpass chamber, these elements all combine seamlessly to produce 15 dB more output at the front of the cabinet than at the rear, thus creating the desired cardioid pattern. This will be a very exciting subwoofer for mobile entertainers, AV production and rental professionals, as well as modestly-sized performance venues that are looking to “keep bass in its place”.


Highly portable, the cabinet features comfortable, aluminum handles and four rear-mounted casters. The cabinet is also fitted with M20 sockets to accept a standard 35 mm speaker pole in either vertical or horizontal deployment of the sub.


We are really looking forward to hearing these in action at the NAMM show later this month and getting them in stock later in the year for you to hear the difference for yourself.
