QSC KLA-181 Active Line Array Subwoofer

General

The KLA-181 is the subwoofer from QSC's KLA series. That series consists of a strong line array system, of which the 18-inch subwoofer takes care of powerful bass. Thanks to its woofer, the KLA-181 has a frequency response of 38 Hz. Its frequency range extends even further - bass tones as low as 33 Hz are still reproduced. When you combine that with the powerful amplifier, you get a maximum sound pressure level of 135 dB.

QSC KLA-181: Double the Power

As one might say: bigger is better. It doesn't get any bigger than this though, as the KL-181 subwoofer is extremely powerful. QSC's KLA-181 features an 18-inch woofer, which is powered by a digital amplifier with a continuous power of 1,000 Watts. As the built-in digital amp has a rather low weight, its power-to-weight ratio is kept to a minimum.

A Line Array Subwoofer with Sub-Settings and Phase Reverse

In addition to the Guardrail protection, the KLA-181 also features two sub-configurations. These allow you to adjust the bass reproduction - you can choose between Standard and Deep. The latter gives the lowest tones an extra, natural punch. With the phase reverse option, you can adjust the phase for an uninterrupted music experience.
