About the PowerBass S-1S
From our tech experts at CEN
The PowerBass S-1S is a pair of 1 inch silk dome tweeters from the S Series, rated at 50w RMS with 4 ohm impedance and 91 dB sensitivity. They use neodymium magnets with Ferrofluid cooling, and come with in-line 12dB crossovers. Flush, angle and surface mounts are all included.
Who it suits
Drivers adding tweeters to a car that has none, or replacing a damaged or harsh factory tweeter. The silk dome is chosen for smooth, fatigue-free treble on long drives rather than sizzle. The three mounting options make them easy to place on a dash, pillar or sail panel.
Our tech experts advise
Always run them through the supplied crossovers so they are not asked to play bass. The angle mount lets you aim them towards the listening position, which makes a bigger difference than most people expect. Mounting depth is just 0.75 inch, so they suit shallow spots. Installation is priced per vehicle, so get in touch. 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: What mounting options come with the PowerBass S-1S?
A: Flush, angle and surface mounts are all included, with a mounting depth of 0.75 inch.
Q: Do the S-1S tweeters need a separate crossover?
A: No. A computer-aided in-line 12dB crossover is included for each tweeter, so they receive the correct signal.
Q: Will the S-1S work with a factory head unit?
A: Yes. With a 4-ohm impedance, 91 dB sensitivity and 50 W RMS / 100 W peak power handling, they suit factory and aftermarket systems alike.
