Infinity TSS-SUB4000C

If you're looking to enhance the bass in your stereo system, the Infinity TSS-SUB4000 Powered Subwoofer represents pure sophistication in high-end powered subwoofers. It's configured with Room Adaptive Bass Optimization System (R.A.B.O.S.), that is capable of professionally calibrating the low-frequency response of your room. It features a 12" reinforced cone driver with magnetic shielding, 400W RMS amplification, precision dividing networks, well-braced enclosures, and a wide range of frequencies with superb sound quality and low distortion.

In addition, it offers Metal Matrix Diaphragm (MMD) technology, which adds unsurpassed rigidity and strength to the low-frequency driver. This advanced technology enables this powerful subwoofer to reproduce the tightest "punch" at the highest sound levels in its class. Its stylish design will complement the newest flat-screen Plasma and LCD TVs in your home theater set-up.

• Metal Matrix Diaphragm (MMD)
The low-frequency driver incorporates Infinity's MMD technology, which 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 super low frequencies.
• Room Adaptive Bass Optimization System
R.A.B.O.S. is a sophisticated low-frequency calibration system that offers the ability to identify the dominant low-frequency response characteristic of your room. Once this is achieved, R.A.B.O.S. provides the tools needed to optimize the low-frequency characteristics of the speakers to the room they are in, exactly as the professional sound engineers calibrate sound.
• R.A.B.O.S. Calibration Kit
This subwoofer is packaged with the R.A.B.O.S. calibration kit which includes:
• Specialized Sound-Level Meter
• Test CD
• Instructions
• Measurement Templates
• Width Selector
• Adjustment Key
• Low-Pass Selector
This subwoofer offers a Low-Pass switch that essentially adjusts for low-frequency effects (LFE) single output, and L/R subwoofer dual outputs from your receiver.
• 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.
• Powerful 400W Digital Amplifier
A powerful 400W of power makes this subwoofer an ideal choice for the most demanding of situations.
• Magnetically Shielded
The housing is designed with magnetic shielding, preventing undesirable interference that causes distortion.
