Know before you buy
The sealed cabinet design allows for a more compact footprint while providing tight, accurate, and highly controlled bass response. It is ideal for listeners who prioritize musicality and precision over the sheer, boomy output often found in ported subwoofers.
Yes. The SB13-Ultra features both stereo line-level RCA inputs and balanced XLR inputs, making it compatible with a wide range of home theater receivers, pre-amplifiers, and professional audio gear.
The integrated digital signal processing includes a two-band parametric EQ that allows you to tune the subwoofer to your specific room environment. This helps minimize unwanted acoustic peaks and ensures a smoother, more balanced bass performance at your listening position.
With 1000 watts of RMS power and a high-excursion 13.5-inch driver, this subwoofer is capable of delivering significant output. While its compact size makes it versatile for various spaces, it has the raw power necessary to anchor a high-performance home theater system.
The cabinet measures 17.4 inches on all sides, but you should account for the overall dimensions of 17.9 inches high by 20.4 inches deep to accommodate the driver and rear-mounted amplifier. Ensure you have a few inches of clearance around the back for cable connections and proper airflow.
The subwoofer has a frequency response starting at 20Hz, which allows it to reproduce the deepest cinematic sound effects and low-frequency musical notes with authority and clarity.
