Infinity REF1000S Reference 10 Inch Low profile Subwoofer with SSI (Selectable Smart Impedance)

Infinity’s latest Reference subwoofers offer incredible installation flexibility. Their low-profile design allows them to fit perfectly into even the most shallow of enclosures — great for today’s compact cars. Polypropylene woofer cones deliver exceptional bass response at frequencies as low as 35Hz. But what makes these subs really stand out is their Harman-proprietary SSITM (Selectable Smart Impedance), which allows the subwoofer to present the amplifier with either a 2 or 4 ohm load at the flip of a switch. In the box: 1 Reference 1000s subwoofer 1 Owner's Manual 1 Technical Data Sheet 10” Shallow Mount Subwoofer Audio Specifications Nominal Impedance - 2 ohm or 4 ohm, switch selectable Power Handling (RMS) - 200W Frequency Response - 35 – 175 Hz Sensitivity - 89dB Power Handling (Peak) - 800W Dimensions Diameter (in)10-9/16" Mounting Diameter (in)9-1/2" Mounting Depth (in)3-5/16" Because today’s compact cars offer less space, the Infinity Reference Subwoofers are designed to fit into small enclosures. They’re slim, sleek, stylish, and don’t sacrifice on sound. Unlike most dual-voice coil woofers, which provide either 1 or 4 ohms or 2 or 8 ohms, the Infinity Reference Subwoofers allow the listener to 2-ohm and 4-ohm at the flip of a switch, providing the two most often used impedances from a single woofer. This allows the system designer unparalleled flexibility in extracting every last watt from your amplifier without compromising stability and thermal safety margins. Your audio is filled with delicious sounds. Unfortunately, you’re not always hearing them all. With lows that dig down into the depths of 35Hz, you’ll hear the low-end frequencies you’ve been missing.
