About the Alpine SWT-10S2

Right size, right sound

Here's a big bass breakthrough for truck lovers. Alpine engineered their SWT-10S2 10" subwoofer to go behind your seat, and sound especially good in the limited space of a truck cab.This deep-sounding, high-performance sub works well in shallow enclosures that'll fit behind or under the seat in your truck. A "high amplitude" surround allows more cone travel than a regular sub, so the SWT-10S2 can push more air and play louder.

Right size, right sound

Here's a big bass breakthrough for truck lovers. Alpine engineered their SWT-10S2 10" subwoofer to go behind your seat, and sound especially good in the limited space of a truck cab.This deep-sounding, high-performance sub works well in shallow enclosures that'll fit behind or under the seat in your truck. A "high amplitude" surround allows more cone travel than a regular sub, so the SWT-10S2 can push more air and play louder.

Airflow ensured

Subs get hot as they play, and the heat usually gets vented away via a port in the back of the sub's pole piece. Alpine recessed the pole port and added cooling air vents on the sides of the frame, allowing you to use an enclosure with an inside clearance of as little as 4-3/16" without blocking critical air flow. An SWT-10S2 will work well in either a ported or a sealed box, so you can get your favorite kind of bass tone, boomy or tight.

The power it takes

This single voice coil, 2-ohm sub will draw maximum power from most subwoofer amplifiers. For top performance, you'll want to pick an amp that delivers between 300 and 500 watts RMS at 2 ohms.

To drive this single subwoofer, we recommend a mono amplifier rated between 375 and 750 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Great sub for an underseat sub!

Thomas from Ozark, AL on 11/1/2018

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

I needed a shallower profile sub to fit under the rear seat in my hunting/fishing truck ( Avalanche) . Installed in a sealed .65 cubic foot box and my initial reaction was " wow, that's more than I expected from a shallower sub in a small sealed enclosure. I'm more into sound quality than absolute spl so this fits my needs well and blends nicely with the Morel components I'm running for the front stage.

Pros: Well controlled with nice punch plus it fits in a tight space.

Cons:

Awesome sub. Definitely go ported.

Paul from Richlands, NC on 6/4/2017

Verified employee purchase (What's this?)

After 30 years in car audio I've owned dozens of subs in every kind of enclosure. I bought a standard cab 95 F150 to be my occasional work truck for lumber runs etc. I started gutting the interior and replacing everything, Ended up being my favorite daily driver. I decided to go all out with a blue top (for the extra posts), 150 amp alternator, and 2/0 welding wire. You know there is little to no room in a standard cab. I'm 6'5" and need that seat back and hated the idea of having to use an 8" for sub duty because 8"s just can't do serious sub duty. Under the drivers side of the bench is a PPI 2050AM and crossovers for the Infinity Reference set. Under the passenger side after measuring the well area I bought a budget amp I'd normally never admit: a Jensen DUBa1100D. I put 2 of the Alpine SWT10S2 in their recommended sealed volumes side by side in their own chambers sharing an alleged 550 watts RMS on tap. With a -3db at 50Hz I was disappointed because I'm a 20-40Hz addict. So I modeled them on my software and found the 1.3 cu ft volume of the box was perfect. I removed the divider and 1 of the subs,added a slot port tuned to 29Hz to the bottom side of the box. It's been 3 years now. I've just got around to writing this review. I've been pushing 1 SWT-10S2 with 800 watts RMS in the ported box and love it. 1 ported (on less power) is so much louder and LOWER than 2 sealed! I keep the other sub as a spare but haven't needed it. If I hear it stress I back off a bit.

Pros: Designed for maximum ventilation. Magnet even has vent channels. Can be placed with motor touching rear wall of enclosure. Handles mad power. Plays 30Hz like a boss in ported enclosure. Single voice coil. Built perfectly deep for a standard cab truck box. (I'm not a fan of most of those "shallow mount" subs with their 50Hz -3db)

Cons: Not really a full con but... Contacted Alpine about a grill. They told me it's designed with the giant trim ring to be its (only) protection against the back of your (truck) seat. If you use this anywhere else just be mindful.

Good value and great sound

Silverado from Smithfield NC on 3/10/2015

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

These subs had me wondering about power at first with the 350 watt RMS rating. I'm running two wired down to 1 ohm and putting 200 watts on each via the sub channel of a memphis baby belle amp and they sound great. Very smooth sound and good looks. I didn't have any space issues but these subs are a shallower mount for those who need the space. I'm impressed with them like all the Alpine products I've used in the past. They seem to be built well.

Pros: Sleek looks Great sound quality Will perform well on 200 watts RMS

Cons: Haven't found any yet

Product Research

Features

HAMR Surround: The High-Amplitude Multi Roll (HAMR) Surround Design allows for extreme excursions without sacrificing valuable cone area.

Speaker Terminals: The spring post terminals will accommodate single banana plugs or bare wire up to 8-gauge.

Gasket Cover: Alpine uses a Concealed Mount Gasket System to cover the mounting screws for a clean look. The black rubber gasket ring comes already installed on the woofer and needs to be removed before drilling the mounting screws (not supplied). The gasket ring then snaps back into place once the woofer is mounted.

Recommended Sealed Box Volume: The recommended sealed box sizes range from 0.35 ft³ to 0.82 ft³. Within this range, the ideal size is 0.47 ft³.

Recommended Vented Box Volume: The recommended vented box sizes range from 0.75 ft³ to 1.27 ft³. Within this range, the ideal size is 1.24 ft³. A slot port with the following dimensions should be used: 10" (wide) x 1" (tall) x 20" (long).

My last sub was an Alpine and sounded great! This one has the shallower mounting depth I need for my new enclosure. [ Michel  Jul 16, 2017 ]

4 questions already asked

Q
How will this subwoofer perform in an van? I would put it in a sealed box according the recommended specs. That means, instead of a small cabin, the woofer would play in a spacious area.
[ splash  Jul 08, 2018 ]

Alpine's SWT-10S2 subwoofer can still work just fine in a van. It's described as a "truck" subwoofer mostly due to its shallow mounting depth which allows it to fit more easily into trucks than other subs; but it will still perform well in other vehicle types as well. For more details or to discuss further, please feel free to contact an Advisor directly by phone (888.955.6000) or online chat. Thanks!

With it being 300W RMS and I'm running two of them. What would be the ideal amp?

Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.

Q
I see the speaker depth is about 4.2". With the internal venting exiting the rear center of the magnet, is any additional depth required to let this driver perform properly?
[ Guest  Oct 20, 2016 ]

There is no mention on the included spec sheet how much is minimum. What's not easy to see is the face of the magnet has indented vent channels from the giant voice coil vent, across the magnet to the outside. I've been cranking bass enhanced music with mine responsibly with 700w RMS in a 1.3'cu port tuned to 28Hz, for well over a year now. I'd recommend the ported box or the largest recommended sealed box. I found that in sealed volumes, the -3db frequency is just too high to me (50+Hz compared to 30Hz for the ported -3). My opinion is the ported enclosure allows the driver to perform properly with minimal ventilation.
[ Paul  Oct 26, 2016 ]
A
Michael is right. As long as you can fit the subwoofer without it bottoming out in the box, then it will work. There is not requirement for extra depth beyond what is needed for the subwoofer to physically fit. HTH! My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=101
