About ESB Harmony
The Harmony brand launched in the 1980s alongside ESB's first home loudspeakers. Car speaker production followed in the 1990s, combining high-quality performance at a lower price than ESB's own range while aiming for full-spectrum, high-fidelity sound. The Harmony line has since returned with a refreshed range of products.
For a step up in the ESB component range, the ESB 8.6K3 Ottomila Series 6.5 inch 3-way component system offers 160W RMS handling.

About the ESB Audio HB1.6K2X
From our tech experts at CEN
The ESB HB1.6K2X is a 2-way component speaker system from ESB's Harmony range, not a pair of tweeters. It pairs pressed paper cone woofers with silk dome tweeters on neodymium magnets and an external 12 dB tweeter crossover. It handles 65w RMS and 130w transient at 4 ohm, with 92 dB sensitivity and a 65 Hz to 20 kHz range.
Who it suits
Drivers who want better stereo imaging than a coaxial can give, at an accessible price. Harmony is ESB's value line. If you would rather keep the tweeter in the door, the HB1.6C is the coaxial version, and the 1.6K2X is the 90w RMS step up.
Our tech experts advise
Mount the tweeters high on the door or pillar and aim them towards the listening position. The 92 dB sensitivity means they work from a head unit, though an amplifier brings out more. Installation is priced per vehicle, so get in touch with your make, model and year.

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 crossover does the ESB HB1.6K2X use?
A: It comes with a 12 dB tweeter crossover that filters the signal to the silk dome tweeter.
Q: How much power can the HB1.6K2X handle?
A: It is rated at 65W nominal (RMS) and 130W transient power, with a 4 ohm impedance and 92 dB sensitivity (2.83V/1m).
