Maximum bass output

With over 40 years of experience, Alpine has the know-how to deliver the kind of hard-hitting bass you want. The R2-W10D4 10" sub capitalizes on this knowledge with a new motor structure with double-stacked magnets for deeper bass and tighter sound. Its Kevlar-reinforced pulp cone features a durable HAMR Santoprene™ surround that allows for huge amounts of excursion, and an oversized poly ceramic dust cap supplies rigidity to keep the sound tight. It's the perfect sub for bassheads that want the best of both worlds: accurate response and otherworldly thump.

A versatile performer

The R2-W10D4 handles up to 750 watts RMS, so it's ready for your high-powered amp. Its dual oversized 4-ohm voice coils offer wiring flexibility for multiple subwoofer setups. Since it works well in sealed or ported enclosures you'll enjoy your music the way you like to hear it.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible.

Kevlar Reinforced Pulp Cone: This Alpine R-Series subwoofer has a two-piece structural parabolic Kevlar reinforced pulp cone. Kevlar adds strength and tear resistance to the woofer cone while maintaining the benefits of a pulp cone design. There is also an oversized inverted polypropylene/ceramic composite dust cap, which increases rigidity and reduces cone distortion at extreme volume levels.

HAMRS: The woofer features a High Amplitude Multi Roll Surround (HAMRS), made of Santoprene Rubber, that allows a large linear excursion and greater SPL. The HAMRS design allows extreme excursions without sacrificing valuable cone area.

Progressive Spider: The progressive spider has reinforced layer tinsel leads to ensure reliable and consistent control of the tinsel leads and eliminate any mechanical noise or interference often seen in high excursion cone designs.

Compound Radius Curve Pole Geometry: Alpine's Patented Compound Radius Curve pole geometry ensures a symmetrical magnetic field, while optimizing flux density to reduce distortion and further improve power handling and output.

Dual Voice Coils: For system flexibility, the woofer has two 4Ω voice coils. When the voice coils are wired in parallel, the woofer presents a 2Ω load; when wired in series, the woofer presents an 8Ω load.

Spring Terminals: The spring post terminals are all located on one side of the woofer. The terminals will accept bare wire up to 8-gauge, pin connectors, or single banana plugs.

Jumpers: Included with the woofer are two voice coil terminal jumpers, allowing you to easily wire the voice coils in parallel (for a 2Ω load) or series (for an 8Ω load).

Enclosure Compatibility

Sealed Box Volume: The recommended sealed box volume (gross) range is from 0.48 to 0.93 ft³ cubic feet, with 0.58 ft³ cubic feet being the ideal size.

Ported Box Volume: The recommended ported box volume range is from 0.83 to 1.38 ft³. The ideal size is 1.33 ft³ using a slot port measuring 10" (width) x 1½" (height) x 19½" (length), resulting in a tuning frequency of 37 Hz.

7 questions already asked

I have a five channel amplifier. The sub output is rated 350 W x1 at 4 ohms or 550 W x1 at 2 ohms. Is this enough power to make this sub sound good or should I consider a less power-hungry sub?

terry Aug 25, 2024

1 answer

Hey Terry, thanks for the question. So general rule of thumb is getting to 70% or more of a subs max output to ensure we have enough power to drive it. I can confirm your amp now will have enough power to properly push this sub and make it sound as good as it can.

red Aug 26, 2024 (Staff)

What amp would be best to pair with this sub? I'm not planning on running crazy power out of the sub, Just something to compliment my speakers. Also is this to much subwoofer for my application?

steven Jun 09, 2024

1 answer

Greetings Steven. Thank you for your question. Not sure what else you got going on in your system, but this is a healthy subwoofer. You want to be around 80% of the maximum RMS which is 750. Somewhere between 600-750 watts is what you want to git this. https://www.crutchfield.com/p_500S2A60M/Alpine-S2-A60M.html?tp=35834 https://www.crutchfield.com/p_500R2A75M/Alpine-R2-A75M.html?tp=35834

How much air space does this speaker take up inside the box?

gary Jun 09, 2024

1 answer

So the physical size of the subwoofer itself should not come into play when calculating the air space volume of a box. The box needs to be measured at the recommended specs without the subwoofer, in this case, sealed box volume: 0.48-0.93 cu. ft. or ported box volume: 0.83-1.38 cu. ft. while having a top-mount depth of 5.975" so the sub can fit into the box.

red Jun 09, 2024 (Staff)

I know It says 750rms think it would handle 1000rms or should I get the other option and run 600 rms at 4ohm amp puts out 1000 at 2ohm and 600 at 4ohm?

kenny Jul 03, 2022

1 answer

The Alpine R2-W10D4 can only handle up to 750 watts rms. We do not recommend powering subs over their rated rms. If you are using an amplifier that is outputting 1000 watts at 2 ohms, it would be better to use two of the 600 watt SVC 4 ohm subs (or DVC 2 ohm subs) that wire down to 2 ohms to prevent any damage or electrical issues.

allison Jul 03, 2022 (Staff)

If I put this sub in a sealed box with .93 cubic feet, would this be OK for the sub since it's on the high end? Sound quality and whatnot. On your site the recommended size is .58. It's a custom box and would fit under the seat of my truck.

sammy Jun 09, 2022

1 answer

We recommend a range of 0.48-0.93 cu. ft. for this sub in a sealed box, so that would work well.

abby Jun 09, 2022 (Staff)

Would a 2 sq ft ported box be good for this sub? I know it exceeds recommended box dimensions but have read so many people preferring the larger boxes in the last generation R series sub.

ethan May 02, 2022

1 answer

Generally we don't recommend trying to make a box work that's larger in air space than the sub is rated for. If the box were too small then you could use a product like polyester stuffing around the magnet to give an impression it's in a larger box, but not the other way around.

abby May 05, 2022 (Staff)

Would the Alpine S-A60M S-Series amp be enough to power this at 2ohm 600watt? Or would it be considered underpowered as RMS for this at 2ohms is 750watt?

parth Apr 16, 2022

1 answer

No. Do not get this amp thinking its going to be a full 600w rms. It feells more like 450 bc it cant even make a kicker l7 10in rumble. I got rid of this alpine amp and got a skar one for 180 and its so much better. Please get smaller subs or a bigger amp

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.

Our Listening Kit

To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. It’s available for a nominal rental fee, and includes a $25 Crutchfield merchandise credit.
