Know before you buy
The cylindrical design allows for a larger internal volume compared to a traditional box, which helps the subwoofer achieve deeper bass extension and higher output while maintaining a smaller footprint in your room.
Yes, you can use the included port blockers to tune the subwoofer's frequency response. While it comes tuned to 25Hz, you can extend the low-frequency output down to 16Hz depending on your preference and room acoustics.
Yes, the unit features adjustable gain, crossover, and phase controls. These allow you to fine-tune the subwoofer's output to blend seamlessly with your main speakers for a balanced soundstage.
The 525W BASH amplifier is highly efficient and capable of delivering clean, massive output, reaching up to 107dB. It is designed to provide plenty of headroom for dynamic movie soundtracks and demanding music.
The subwoofer stands 32.5 inches tall with a 16-inch diameter and weighs 70 pounds. Because it is a freestanding unit, ensure you have enough floor space to accommodate its height and the necessary clearance for the ports.
The 12-inch aluminum-cone woofer is designed for rigidity and speed. This construction helps the subwoofer produce tight, fast, and accurate bass transients rather than the muddy or boomy sound often associated with softer cone materials.
