Description
Overview
The Infinity REF1000S is a 10-inch shallow-mount subwoofer from Infinity’s Reference Series. It is designed to give a good sub-bass punch in installations where space is limited (tight boxes, compact trunks, shallow mounting depth). It also has a Selectable Smart Impedance (SSI) feature allowing you to switch the nominal impedance between 2 Ω or 4 Ω to match different amplifiers or wiring setups. woofersetc.com+4th.infinityspeakers.com+4sonicelectronix.com+4

Enclosure Recommendations
To get the best out of this sub, the following enclosure types and volumes are suggested: infinityspeakers.com+1
| Enclosure Type | Recommended Internal Volume | Notes |
|---|---|---|
| Sealed | ~ 0.5 cu ft (≈ 14.15 liters) infinityspeakers.com | Tight, accurate bass, better for low frequencies, but less output than ported. |
| Vented / Ported | ~ 1.25-1.50 cu ft (≈ 35-42 liters) depending on port diameter/length infinity-caraudio.com.au+2infinityspeakers.com+2 | More output in mid-bass; good if you want louder bass. Must tune port carefully. |
| Band-pass | There are recommended band-pass designs in the spec-sheet (sealed + ported chambers) for maximum output. infinityspeakers.com |
Performance & Trade-Offs
What this sub does well, and what limitations to expect:
Pros:
-
Good low end for a 10-inch shallow sub, especially when paired with the right enclosure.
-
Flexibility in matching to amplifiers thanks to its SSI switch.
-
Relatively high peak power (800 W) for short bursts without distortion.
-
Shallow depth helps in tight installs (small trunk, under-seat, behind-rear seats, etc.).
Cons / Things to Watch:
-
Although the response goes down to ~35 Hz, you won’t get the extremely deep bass (“felt” bass) of larger 12- or 15-inch subs. If you want rumble down in the 20-30 Hz region strongly, a larger or more powerful sub might be better.
-
Sensitivity is moderate (89 dB) — you’ll need enough power from the amplifier to drive it well. Switching to 2 Ω helps with more current draw but you need a capable amp.
-
The impedance switch is physical and located on the back of the sub; you may need to remove the sub or access the back to change. Be careful when installing so that you don’t damage that component. Some user reviews mention this. sonicelectronix.com
-
Ported enclosures usually trade off low-frequency extension and tightness versus output in mid bass; for really clean bass and less distortion, sealed is safer.

Very good shallow-mount sub; sounds rich and tight, though you’ll need a decent amp to get the most out of it.
