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.
Frequency Response As Low as to 27Hz
Your audio is filled with delicious sounds. Unfortunately, you’re not always hearing them all. With lows that dig down into the depths of 27Hz, you’ll hear the low-end frequencies you’ve been missing.
OEM-Level Reliability Testing
Infinity tests every speaker design to the same rigid specifications as the automakers, subjecting them to extreme conditions that would break lesser speakers. We freeze them, bake them, shake them, blast them with ultraviolet light and drive them at full power for days to make sure your audio investment lasts for years.

Impedance: The Reference 1200s has a Selectable Smart Impedance switch (SSI), allowing you to easily change the speaker impedance. Choose between 2Ω and 4Ω.
Sealed Box: Infinity recommends a sealed enclosure with an internal volume of 0.75 ft³. Sealed enclosures provide the most control over a woofer, will handle more power, and provide more accurate sonic reproduction, making them suitable to all types of music.
Ported Box: Infinity recommends a ported enclosure with an internal volume of 1.75 ft³ with one 4" diameter x 10" long port. Ported (or vented) enclosures provide better efficiency in the 40-60Hz range, and are suitable for use with smaller amplifiers, giving you more bass output from less power. However, this efficiency comes at the expense of sound quality at low frequencies (40Hz and below), and control. A subsonic filter is recommended when using a ported enclosure.
Free-Air: While the Reference 1200s can be mounted in free-air (infinite baffle), the power handling decreases by half.
Bandpass Box: Infinity recommends a bandpass enclosure with a sealed chamber volume of 1 ft³ and a ported chamber volume of 1.75 ft³ with one 4" diameter x 7.5" long port. Bandpass enclosures often provide the most output available from any amplifier and subwoofer combination, but at the expense of sonic
