OPTISOUNDSB10T5A-V3 Optisound 10 inch 900W compact bass enclosure
The Optisound SB10 uses passive radiator technology to replicate the output of a larger ported box while keeping a smaller footprint than a sealed enclosure — useful where boot or cabin space is tight. The down-firing subwoofer and passive radiator work together for strong bass reproduction without eating into your van's load area.
The enclosure is engineered for direct installation into Volkswagen T5/T6 platform vehicles. Custom brackets secure it to the seat base, creating a floating effect above the floor for a clean, factory-like finish.
PERFORMANCE – Passive radiator and down-firing technologies deliver strong bass from a compact enclosure.
COMPACT YET POWERFUL – The ultra-compact footprint and shallow height make this subwoofer well suited to space-limited installations without sacrificing bass output.
EFFORTLESS INSTALLATION – The POWERBOX400.1 amplifier can be installed using the Vibe rapid fit kit, keeping setup quick and straightforward. If you need a non-vehicle-specific active solution, the Vibe Active Subwoofer Enclosure 12 inch 350W RMS is also available.
SEAMLESS OEM INTEGRATION – The slim, compact profile of the SB10 is designed to blend in with the interior of modern vehicles.
ACTIVE BASS ENCLOSURE – The SB10 comes supplied with a POWERBOX400.1 amplifier as standard.

About the Vibe OPTISOUNDSB10-V3
From our tech experts at CEN
The Vibe OPTISOUNDSB10-V3 is an active 10 inch subwoofer enclosure built for Volkswagen T5 and T6 platform vans. It uses a down-firing driver with a passive radiator, rated at 300W RMS (900W peak), and comes supplied with a POWERBOX400.1 amplifier. Custom brackets fit directly to the van's seat base for a clean, factory-style finish.
Who it suits
This suits VW T5 or T6 owners who want strong bass without losing load space or accepting a visible aftermarket installation. The passive radiator design delivers output comparable to a larger ported enclosure in a smaller footprint. For an alternative T5/T6 seat-base option, see the Vibe T5 T6 Seat Base Sub.
Our tech experts advise
The included POWERBOX400.1 amplifier is matched to the enclosure, so no separate amp is needed. Confirm your T5 or T6 variant before ordering, as the custom brackets are vehicle-specific. Installation is priced per vehicle — contact us to arrange fitting.
