The Alpine SS-SB10 is a sealed, ready-to-fit enclosure loaded with a 10-inch S-Series shallow subwoofer: a 2-ohm load, a front-mounted neodymium motor and 300 W RMS power handling, all in a polymer box 114 mm high. Alpine quotes a 35 Hz to 200 Hz response and 11 mm of linear excursion, and the box measures 470 x 114 x 318 mm. Its India MRP is ₹79,999, more than the powered PWE-M770 and PWE-S800 at ₹34,999 each, and unlike them it needs a separate amplifier. It suits owners of sedans and SUVs who want real 10-inch bass without losing the boot to a big box. See today's price on our Alpine SS-SB10 product page.


Alpine SS-SB10 10-inch shallow loaded subwoofer enclosure

Quick summary

  • A 10-inch shallow sub pre-installed in a sealed polymer cabinet only 114 mm high, so there is no box to design or build.

  • Rated at 300 W RMS for a 2-ohm load, with 11 mm of one-way linear excursion.

  • Passive: it needs an amplifier, and Alpine names the S2-A55V among the models it is optimised for.

  • Four adjustable, foam-padded steel brackets allow flexible mounting and reduce vibration, according to Alpine.

All figures come from Alpine Australia's SS-SB10 page, which doesn't list sensitivity, weight or peak power, so neither do we. Its specification line calls the voice coil a single 2-ohm unit, while its description says dual voice coils wired in parallel for a 2 Ω load; both agree on the 2 Ω load, so we quote only that.


Why a loaded shallow enclosure makes sense

Getting good bass from a 10-inch subwoofer usually means a box designed for that driver, built from scratch and then fitted. The SS-SB10 removes those steps: Alpine has already matched the woofer to its sealed cabinet. Sealed boxes are generally chosen for tight, controlled bass rather than maximum boom, which suits most music in a closed car cabin.


The shallow S-Series driver is what makes the 114 mm height possible. Its neodymium motor is mounted on the front, so the magnet doesn't hang out behind the cone, which is how shallow subwoofers save depth. Alpine pairs that with what it calls its Gen2 DD Linear magnetic circuit and quotes 11 mm of linear excursion. The cabinet is rugged polymer; Alpine doesn't publish a weight on its Australian page.


Alpine quotes 35 Hz as the lower limit, given without a tolerance, so read it as the edge of the range. A compact sealed 10-inch like this is about adding weight to everyday music, from rock and pop to Bollywood and electronic tracks, rather than chasing competition-level output.


Amplifier pairing and wiring

This is a passive enclosure, so budget for an amplifier. Alpine says the SS-SB10 is optimised for its S2-A55V, KTA-200M or KTA-30MW amplifiers. Of those, we sell the Alpine S2-A55V, and on paper the match is exact: its subwoofer channel is rated at 300 W RMS into 2 Ω, matching the SS-SB10's load and power rating. Its four other channels, 40 W RMS each into 4 Ω, can run the door speakers, so one amplifier drives the whole system.


A larger mono amplifier would work too, but anything rated well above 300 W RMS at 2 Ω needs its gain set carefully. Run a properly sized, fused power cable from the battery, set the low-pass filter, and a subsonic filter if your amplifier has one, to protect the woofer, and set gain with a test tone rather than by ear. Our guide on the role of an amplifier covers the basics.


What owners and reviewers say about the Alpine SS-SB10

When we checked in October 2026, we found no owner reviews or independent tests that we could read for the SS-SB10. Crutchfield lists it in the US, but its review content did not load for us, so we can't report what buyers there say. Alpine Australia's page is promotional. If you run an SS-SB10, we'd like to hear how it performs in your car, and we will add genuine feedback here when we have it.


SS-SB10 vs Alpine's powered subs and separate drivers

The powered Alpine PWE-M770 and PWE-S800 both carry a ₹34,999 MRP and need no separate amplifier. The PWE-M770 pairs a 7 x 7-inch woofer with a 150 W RMS amplifier in a box 74 mm deep, and the PWE-S800 uses an 8-inch woofer with a wired controller. Both are simpler and cheaper, but neither offers a 10-inch cone with a 300 W RMS rating.


Building your own system is another route. The Alpine RS-W10 shallow driver is rated at 600 W RMS but carries an ₹82,999 MRP on its own and needs a sealed box of 13.9 to 29.4 litres. A conventional Alpine R2-W10 (₹41,999 MRP, 750 W RMS) needs 152 mm of mounting depth according to Alpine UK, more than the SS-SB10's entire height. Either way, you add the cost of a box and the work of building it.


Who should buy it, and who shouldn't

Buy the SS-SB10 if you want 10-inch bass in a slim, factory-built box, your car has a flat boot floor or a space behind or under a rear seat, and you are buying an amplifier such as the S2-A55V at the same time.


Look elsewhere if you want a single plug-in unit with its own amplifier, in which case a PWE model is simpler. The same goes if you are chasing maximum output, which calls for larger drivers and bigger boxes, or if you want owner reviews first, since we couldn't find any we could read.


Installation notes for Indian cars

On a boot floor, the box's 114 mm height means luggage can still sit alongside it; check the 470 x 318 mm footprint against your boot. If your SUV or pickup has space behind or under a rear seat, a box this slim may fit there, but measure carefully, including seat movement. Crutchfield's US listing describes it as a down-firing design, which Alpine Australia's page doesn't mention, so check the orientation and floor clearance with us before you plan the mounting. If you drive a car we've covered with a vehicle-specific enclosure, such as the Toyota Hilux stealthbox, compare that route too.


Use all four brackets: Indian roads punish loose boxes, and the foam padding is there to cut vibration. Keep the amplifier ventilated and route the power cable away from sharp edges. VA3 Car Studio in Ghaziabad offers professional installation.


Price and where to buy

The SS-SB10 has an MRP of ₹79,999. We often sell below MRP, so check the current offer on the SS-SB10 listing. Every unit we sell is a genuine Alpine product.



The bottom line

The SS-SB10 brings the largest woofer of Alpine's compact bass options here: a 10-inch shallow sub matched to a sealed box only 114 mm high, rated at 300 W RMS, with brackets for flexible mounting. Add an amplifier, such as the S2-A55V, one of three that Alpine suggests, and you have a properly matched 10-inch sealed sub that keeps a low profile in the car.


Alpine SS-SB10 FAQ

Does the Alpine SS-SB10 need an amplifier?

Yes. It is a passive loaded enclosure rated at 300 W RMS into 2 ohms. Alpine says it is optimised for the S2-A55V, KTA-200M or KTA-30MW; the S2-A55V's subwoofer channel delivers 300 W RMS into 2 ohms.


How shallow is the Alpine SS-SB10?

The whole enclosure is 114 mm high, 470 mm wide and 318 mm deep, according to Alpine. That can suit a boot floor or a space behind or under a rear seat, but measure your car first.


Is the SS-SB10 sealed or ported?

Sealed. Alpine describes a sealed polymer cabinet pre-loaded with a 10-inch S-Series shallow subwoofer, which generally gives tight, controlled bass rather than the extra boom of a ported box.
