QXS6.3C
16 cm (6") + 8 cm (3") 2.1-Way Component System
Bad sound in the Mercedes Sprinter? The precisely fitting ESX QUANTUM QXS6.3C 2-way speaker door system with matching broadband center speaker for the dashboard can help. The very high-quality set is easy to install, even for non-professionals, thanks to well thought-out plug+play parameters. Compared to the original loudspeakers, the improvement is clearly audible and ensures relaxation on every trip. The lightweight ESX mid-bass drivers with ABS baskets fit perfectly into the original door openings without additional adapter rings. The 16 cm woofers deliver powerful bass down to 50 Hz.
There are integrated sockets on the baskets to accommodate the speaker plugs that are factory-fitted in the vehicle. With an astounding efficiency of 93dB/2.83V/1m and a load impedance of 3 ohms, the ESX Quantum 2-way component set is a joy to play with.
The center loudspeaker has the same high-quality fiber-reinforced membrane as the woofer and, compared to the original center, has a significantly improved voice reproduction in the middle range, which is particularly important for speech and singing. Of course, the ESX center speaker is equipped with the SOS function integrated in the vehicle. Proven, 25 mm neodymium tweeters with silk dome are used in the treble range. They play very cleanly and with high resolution up to 24,000 Hz. A 6 dB cable crossover is integrated in the connection cable, which ensures very clean separation at 3500 Hz.

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.
