QXS6.3C 16 cm (6") + 8 cm (3") 2.1-way component system
The ESX Quantum QXS6.3C is a 2.1-way door and centre speaker upgrade for the Mercedes-Benz Sprinter. Plug-and-play connections make installation straightforward, with no adapter rings needed — the lightweight ABS basket mid-bass drivers drop straight into the original door openings. The 16 cm woofers reach down to 50 Hz, and integrated factory-plug sockets on the baskets connect directly to the vehicle's existing wiring. Sensitivity is 93 dB/2.83V/1m with a 3 ohm load impedance.
The 8 cm dashboard centre speaker uses the same fibre-reinforced cone as the woofers. It delivers noticeably improved midrange clarity for vocals and speech, and retains the vehicle's integrated SOS function.
The 25 mm neodymium silk dome tweeters extend up to 24,000 Hz. A 6 dB cable crossover integrated into the connection cable provides clean separation at 3500 Hz.

About the ESX QXS6.3C
From our tech experts at CEN
ESX component speakers, with separate tweeters for mounting where you will actually hear them.
Who it suits
Drivers building a proper front stage and happy for tweeters to be mounted separately, which usually means a professional fit. ESX builds accessible, vehicle-specific upgrades.
Our tech experts advise
Sizes, adapter rings and harnesses vary by vehicle, year and trim, so we confirm what your car takes before ordering rather than guessing. Door treatment matters as much as the speaker. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: Which Sprinter does the ESX QXS6.3C fit?
A: It is designed for the Mercedes-Benz Sprinter W907 from 2018 onwards.
Q: Does the QXS6.3C centre speaker keep the Sprinter's SOS function?
A: Yes. The ESX centre speaker is equipped with the SOS function integrated in the vehicle.
Q: What is included with the QXS6.3C?
A: Two 16 cm door woofers, two 25 mm silk dome tweeters with cable crossovers, and one 8 cm centre speaker with its own cable crossover.
