Know before you buy
This subwoofer is designed to perform best in rooms up to 400 square feet. Its 10-inch driver and 300W amplifier provide enough output to fill medium-sized spaces with impactful, cinematic bass.
The HT/1003 MKII features a sealed cabinet design. This construction typically results in tighter, more accurate bass response, which is excellent for both fast-paced movie effects and musical clarity.
You can connect the subwoofer using the LFE RCA input for dedicated home theater signals or the standard Low Level RCA inputs. It is designed to integrate easily with most modern AV receivers.
While it is engineered specifically for home theater performance, its balanced design and CarbonGlas driver make it capable of handling music well. It provides the deep extension needed for dramatic movie scores and adds a solid foundation to stereo music setups.
The unit measures 12.5 x 13.75 x 13.75 inches. Its compact footprint makes it relatively easy to tuck into corners or alongside media consoles without dominating your room's aesthetic.
