SPC-10S4: Space Series 10" Single 4 Ohm Low Profile Subwoofer
The Space Series subwoofers deliver strong low-frequency output from a shallow enclosure — ideal for vehicles where boot or door space is tight. The weather-resistant design means they can also be used in open or exposed installations without concern.
Features
- Low-profile shallow-mount subwoofer
- Fibre matrix injection moulded polypropylene cone
- Weather-resistant design
- 3-layer high temp voice coil former
- Optimal thermal efficiency
- Wrap-sealed rubber gasket to protect enclosure interior

AudioControl has over 45 years of experience in car audio. The fibre matrix injection moulded polypropylene cone reproduces bass accurately, while the 3-layer high temp voice coil former handles sustained high-power use. The thermal efficiency design helps keep output clean under load. If you need to integrate the SPC-10S4 into a factory system, AudioControl's LC2i line output converter is a compatible solution for adding an aftermarket amplifier to a high-level speaker output.

About the AudioControl SPC-10S4
From our tech experts at CEN
An AudioControl 10 inch subwoofer, 4 ohm, handling 400w RMS.
Who it suits
Drivers building a system where the bass does real work rather than filling in behind the speakers.
Our tech experts advise
A subwoofer is only as good as its enclosure and the amplifier behind it: box volume and tuning decide what you actually hear, and impedance decides how it should be wired. We build enclosures to suit both driver and vehicle at our Beeston workshop. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs.

Frequently Asked Questions
Q: Do I need an amplifier for this subwoofer?
A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.
Q: What size enclosure does this subwoofer need?
A: The recommended enclosure volume is listed in the Specification tab where the manufacturer provides it. As a rule, sealed enclosures give tighter, more accurate bass while ported enclosures deliver more output. Contact CEN if you would like a recommendation for your build.
Q: What does RMS power mean?
A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.
Q: Sealed or ported enclosure - which should I choose?
A: Sealed boxes are compact and produce tight, controlled bass suited to sound quality builds. Ported boxes are larger and produce more output at low frequencies, suited to those who want maximum impact. Either works well when built to the recommended volume.
Q: Can CEN build or supply an enclosure and fit everything?
A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.
Q: How shallow is the Space Series SPC-10S4?
A: Mounting depth is 89mm. Mounting height is 18mm without the grille and 31mm with it, so it suits shallow installs.
Q: Is the SPC-10S4 2 ohm or 4 ohm?
A: The SPC-10S4 has a single 4 ohm voice coil. A 2 ohm version of the same 10 inch Space Series subwoofer is also available.
Q: Is there a ready-made enclosure for this subwoofer?
A: Yes. AudioControl makes a Space Series 10 inch sealed wedge enclosure, supplied loaded with a 2 ohm Space Series subwoofer.
