HK Audio Linear Sub 1800 A

The built-in crossover handles the frequency splitting automatically, sending the low frequencies to the subwoofer and the mids and highs to your connected top speakers. This eliminates the need for an external crossover unit and ensures a clean, balanced sound across your entire system.

Yes, the 18-inch driver combined with the 1200-watt amplifier is designed specifically for professional sound reinforcement in medium to large venues. With a peak SPL of 132 dB, it provides enough low-end punch to fill a room without struggling.

Absolutely. The unit features dedicated XLR Mid/High outputs, allowing you to daisy-chain your top speakers directly from the subwoofer. This makes integration straightforward regardless of your current setup.

The enclosure is built from 16mm MDF, which provides the structural rigidity needed to withstand the vibrations of high-output bass. While it is robust and designed for professional use, it is still a wooden cabinet, so it is best handled with care during transport.

It features a standard M20 threaded pole mount. This is a secure, industry-standard fitting that prevents the pole from wobbling, ensuring your top speakers remain stable even during high-volume events.

Class D amplification is highly efficient, allowing for high power output in a lighter, cooler-running package. In this subwoofer, it delivers the fast, transient response necessary for tight, punchy bass without adding unnecessary weight or heat.
