About the Option Audio AIR-10 D2
From our tech experts at CEN
The Option Audio AIR-10 D2 is a 10 inch (25cm) dual voice coil chassis car subwoofer with 2+2 ohm coils, a ferrite magnet and 300W RMS power handling. It is sold as a driver only and requires a separate enclosure. Mounting depth is 9.5cm and the unit weighs 2.78kg.
Who it suits
It suits anyone building a custom subwoofer enclosure who wants a capable 10 inch driver to pair with an existing amplifier. Those with very limited boot depth may prefer the Option Audio AIR-F10 D2 flat subwoofer, which offers the same 300W RMS rating in a shallower profile.
Our tech experts advise
The dual voice coil allows flexible wiring: series connection gives 4 ohms, parallel gives 1 ohm — check your amplifier's stable impedance rating before deciding. Your enclosure must allow at least 9.5cm of mounting depth. This driver does not include a box or amplifier. Professional installation is priced per vehicle; visit our Nottingham installation page for details.

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 much power can the Option Audio AIR-10 D2 handle?
A: It is rated at 300W RMS.
Q: What is the mounting depth of the AIR-10 D2?
A: It needs 9.5cm of installation depth.
Q: Does the AIR-10 D2 come with an enclosure?
A: No. It is supplied as a subwoofer chassis (driver only), ready to install in a suitable enclosure.
