Description
The Infinity REF1200S is a 12-inch shallow-mount subwoofer from Infinity’s Reference series designed to deliver strong bass performance while fitting into tight spaces (e.g. compact car trunks, under seats) thanks to its reduced mounting depth. It uses Infinity’s “Selectable Smart Impedance” (SSI) switch allowing choice of 2 Ω or 4 Ω nominal impedance to better match different amplifiers. Crutchfield+2infinity-caraudio.com.au+2

Features & What Makes It Good
-
Shallow Mount Design: Reduced mounting depth (~3.25 in) makes it easier to fit in tighter enclosures, under seats, etc. woofersetc.com+2enrock.com+2
-
Selectable Impedance (SSI): You can switch between 2 Ω or 4 Ω, which gives flexibility in choosing amplifier matching, wiring configurations, etc. Crutchfield+2GearDiary+2
-
Good Low-End Extension: With a low Fs (~22.8 Hz) and response down to ~27 Hz, it can reproduce deep bass well if paired with a proper enclosure. harmanaudio.com+2infinity-caraudio.com.au+2
-
Durable Build: The choice of cone (polypropylene), surround (rubber) etc. helps with reliability, especially in varying car environments. woofersetc.com+1
Enclosure Recommendations
-
Sealed Box: Recommended internal volume ~0.75 cubic feet (≈ 21.2 liters). Good for tight, tight installations, more controlled bass. harmanaudio.com+1
-
Ported (Vented) Box: Recommended around ~1.75 cu ft (≈ 49.5 liters) with a 4-inch port of ~10 in length. Offers more output in the mid-bass region (like 40-60 Hz). harmanaudio.com+1
-
Bandpass enclosures are also supported in the spec sheet for those wanting even more output (with trade-offs in bandwidth and fidelity). harmanaudio.com+2Crutchfield+2
Things to Watch / Trade-Offs
-
In a ported or bandpass box, low frequency extension (below ~30 Hz) might suffer compared to sealed boxes. Also, a subsonic filter is advised when using ported enclosures to avoid damage at very low frequencies. Crutchfield+1
-
The sensitivity is decent (92 dB), but you’ll still need a good amplifier to get maximum performance—especially to reach the peak power safely. RMS power is the more meaningful rating here.
-
Impedance switching: the choice (2 Ω vs 4 Ω) will affect how much current your amplifier must supply; for long cable runs or weaker amps, 4 Ω might be safer.
