With a Power Handling (RMS) of 60W and a maximum Power Handling of 120W, the ZDSB100CS ensures exceptional audio reproduction across a wide range of frequencies.

The tweeters in the ZDSB100CS are crafted from Silk, a material renowned for its ability to reproduce high tones with exceptional clarity and smoothness. Complementing the tweeters, the woofer is constructed from a Sandwich Composite Cone material, delivering balanced and articulate mid-range frequencies.
Utilising Neo/Neo magnets, this speaker system achieves powerful and responsive sound reproduction while maintaining a compact and lightweight design.

About the Phoenix Gold ZDSB100CS
From our tech experts at CEN
A vehicle-specific Phoenix Gold speaker upgrade for the BMW, made to fit the factory locations and connectors without cutting or adapter rings, rated at 60w RMS.
Who it suits
BMW owners replacing speakers that were built to a price when the car was made. Plug-and-play kits keep the work reversible, which matters on a lease or a car you intend to sell on.
Our tech experts advise
Fitment varies by model year, trim and which factory audio system the car left with, so we confirm against your exact vehicle before ordering. An amplifier will get considerably more from them. 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.
