Subwoofer for QSC K8.2

The QSC K8.2 is a highly-rated powered loudspeaker for audio professionals who wants durability and excellent sonic performance without breaking the bank. With just a pair of them, you can fill a medium-sized room with loud and clear sound quality. How loud it can go you might ask. Well the maximum rated SPL at its peak will be 128dB at 1M which is loud enough for most events and usages. The continuous rated SPL at 122dB (@ 1M) is really good too.

This is partly thanks to the Class D amplifier which at its peak, pumps 225 Watts into the 1.4″ high-frequency transducer and a whopping 1800 Watts into the 8″ low-frequency transducer. The frequency response is considered good, and it is between 59Hz to 20kHz (-6dB). The overall bass performance is fine for both small and mid-sized rooms, but if you are planning to use the QSC K8.2 loudspeakers in a large area, you will need support from an active subwoofer.

The bass responses of the QSC K8.2 is precise and clean, and don’t overwhelm the upper registers. There is a lack of low-end punch and the missing sub-bass frequencies do make the overall audio reproduction sound less powerful. If the music you are playing is not bass-heavy, then the QSC K8.2 loudspeakers by themselves should suffice. The QSC K8.2 does particularly well with vocals and acoustic instruments.
