The low-frequency driver incorporates Infinity's MMD technology. MMD consists of a stiff aluminum core, anodized on both sides for superior rigidity and strength. It is 3 times as rigid as titanium, and 85 times more rigid than felted paper. This unique design is capable of eliminating unwanted tonal resonances in the signal path. The end result is a full, clear, tight reproduction of low and high frequencies.
Powerful Digital Amplifier
A powerful 300W of RMS power, and 500W peak power makes this subwoofer an ideal choice for the most demanding of situations.
Phase Control Switch
The Phase switch determines whether the subwoofer speaker's piston-like action moves in and out with the main speakers. Proper phase adjustment depends on several variables such as room size, subwoofer placement and listener position. Adjust the phase switch to maximize bass output at the listening position.
Low-Frequency Effects (LFE) Input
This subwoofer offers a Low-Frequency Effects input that essentially adjusts for low-frequency Dolby Digital/DTS effects from your receiver, and it also offers L/R subwoofer dual (line-level) inputs.
Magnetically Shielded
The housing is designed with magnetic shielding, preventing undesirable interference that causes distortion.
