For over 30 years, Safe and Sound has helped UK drivers get more from their in-car audio — and the S-1ZT from PowerBass is one of the simplest, most affordable ways to do it. This pair of 1″ rare earth zirconium super tweeters adds the crisp, airy high frequencies that dull factory systems lack, lifting detail and stereo imaging without replacing a single existing speaker.
Why choose the S-1ZT?
Most factory speakers sit low in the doors, so the detail in your music fires at your knees rather than your ears. Adding a properly placed pair of tweeters changes that completely — vocals lift to the dashboard, instruments separate, and a flat system suddenly sounds alive. The S-1ZT’s zirconium element is what gives your music that sizzle, and with the crossover already built in, it’s a genuinely simple upgrade to any factory or aftermarket system.
- Crisp, extended highs — the rare earth zirconium element reproduces detail from 5kHz right up to 25kHz.
- Built-in 6dB crossover — no separate components to wire in or hide; everything is integrated into the tweeter.
- Compact surface mount — easy to position on A-pillars, sail panels or the dash for the best possible imaging.
- Effortlessly efficient — 102 dB sensitivity means a big improvement without demanding extra power, while 100W RMS handling keeps headroom in reserve.
Placement makes all the difference
With tweeters, where they go matters as much as what they are — a few centimetres can change the whole soundstage. That’s where the Safe and Sound workshop earns its keep: our installers position and angle add-on tweeters like the S-1ZT every week, and know exactly where they’ll deliver the biggest lift in your particular vehicle. Of course, the surface-mount design also makes the S-1ZT a satisfying DIY job if you’d rather fit them yourself.

Perfect for almost any system
Because the S-1ZT is an add-on rather than a replacement, it works alongside whatever you already have — a standard factory stereo, an upgraded head unit, or a full amplified install. It’s an ideal finishing touch after a speaker or subwoofer upgrade, restoring top-end balance to a system that’s gained low-end weight.
Tip: tweeter placement and angle have a big effect on the end result, and pairing positions left-to-right matters for imaging. If you’d like advice on the best locations in your vehicle, the Safe and Sound team is happy to help before you buy.
