The Mackie HRS120 is a THX-approved, 12 in. active subwoofer that is ideal for applications where precise, low frequency reproduction and flexible monitoring and control options are required. The HRS120 is engineered to work in harmony with the HR824 and HR624.
The Mackie HRS120 Active Subwoofer is one of the most flexible, responsive, and cost-effective active studio sub woofers on the market today. The HRS120 is perfectly suited for professional recording studios and film/video surround post-production facilities that require extremely accurate bass extension to 19Hz and below. It is also an excellent choice for home theater surround sound installations. In addition to surround applications, the HRS120 can add more low-end presence and enhancement to project and professional studios in a standard stereo configuration. Either way, the HRS120 is a must-have for those customers seeking crisp, clear, detailed low-frequency enhancement for virtually any application.
