About the Infinity REF1000S

Low-profile design

Today's compact cars offer less space for a component subwoofer, but Infinity doesn't want you to miss out on the bass you deserve. They designed the Reference Series REF1000S 10" subwoofer to fit into today's smaller enclosures without sacrificing on sound. With response that goes down to 35 Hz, you'll definitely hear the low frequencies you've been missing.

With response that goes down to 35 Hz, you'll definitely hear the low frequencies you've been missing.

Selectable impedance

Unlike most dual-voice coil woofers which allow you to wire the two coils for different impedances, this Infinity sub features a switch which flips between 2 and 4 ohms, the most commonly used settings for a single sub. You'll be able to extract every last watt from your amplifier without compromising stability and thermal safety margins.

Reliability testing

Infinity tests every model under extreme conditions that would break lesser speakers. They 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. Get ready for big bass in a small space.

Amazing.

2017 Toyota Tundra

I had doubts but these speakers exseeded my expectations. They asked for 1.5 Cubic feet ported and .5 cubic feet sealed. What they got was .6 ported, but that was plenty for my taste. These speakers sound amazing with my Alpine MRV-M500. I bought a custom box to fit under my rear seats in my 2017 Tundra. When they hit I smiled from ear to ear :) Thank you Crutchfield.

Pros: Fits in tight spaces.

Cons: Shallow subs are rated with less bass vs non shallow.

Great bass for the size

Randy from Upstate NY on 9/30/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

I purchased this shallow mount Infinity sub for my 2013 F150 supercab. I put the sub in a 0.8 cubic foot box under the rear seat, and I run it with a 220-watt-rms amplifier at 2-ohms. I've never used a shallow mount subwoofer, and I was a bit worried that this would not satisfy my needs. After a week of break-in time, I started to push it a little bit. After a bit of tweaking, I found that this subwoofer is simply excellent. My sound taste is directed towards sound quality, and this sub absolutely complements the 2 pairs of Infinity Primus PR8602cf I installed last month to my Sony HU. I am more than happy with my purchase! Thanks Crutchfield!

Pros: Great bass with proper installation, excellent build quality, won't break your wallet.

Cons: Not a thing

Infinity REF1000S - Great Subwoofer

Bill from San Antonio, TX on 7/16/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

The Infinity REF1000S met all my requirements, shallow mount and 2 Ohm. It provides plenty of bass that can be felt. It's mounted in a custom enclosure and is working great. On the down side, input terminals are two different sizes and no connectors are provided. The manual says the sub can be top or bottom mounted and to use the included foam ring for either installation. The ring was not included.

Pros: Shallow mount, selectable 2 or 4 Ohm

Cons: different size input terminals and connectors not included , install instructions says to use included foam ring but was not included

Good enough sound for small soace

Guest from Ft Myers, FL on 4/13/2017

Verified employee purchase (What's this?)

Great sub for what I need!! Crew cab frontier limited space under seat and this thing works great. I mainly use it for deeper sub filler with my 6.5 infinity components which scream. I'm running 200rms at 4ohm In a sealed box. Had to tune correctly, but with it only 1/4 gain up it thumps!! It defiantly can handle gain up at 3/4 which shakes everything which got neighbors made but I couldn't hear components very well. I'm a crisp clean sound audio junky this set I have is over plenty.

Pros: Good with little power and space

Cons: Took time to tune but great when accomplished.

One works well in Tundra.

Jon from Buford, GA on 3/8/2017

Sounds good for such a shallow sub. Doesn't hit as hard as a traditional deep basket sub, but if space is limited it's a gem.

Pros: Very shallow mount depth. Decent sound output.

Cons: Doesn't hit as hard as a traditional sub.

Quality subs!

Artimus_Cade from Virginia on 5/26/2015

These subs are definitely well built and up to the task. Just make sure you you check the mounting diameter. I didn't and ended up sanding out the holes to get them to fit. Oops... In the end they work just fine. Though looking back I think I would have spent the money for a little more power (personal choice).

Product Research

Features

Impedance: The Reference 1000s 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 0.5 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 1.5 ft³ with one 3" diameter x 7" 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 1000s 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 0.75 ft³ and a ported chamber volume of 0.75 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 accuracy.

Thiele Small Parameters: The Thiele Small Parameters change based on the impedance setting:

    • Revc: 1.8Ω
