Who it suits
Drivers adding or upgrading tweeters alongside Focal Universal speakers such as the ICU 100, or replacing tired factory tweeters. It offers four mounting options: flush, surface, behind the factory grille, or on an angled support.

The factory location option lets you remove it from its support and fit it behind the original grille, which keeps the car looking standard. Aim it towards the listening position where you can. Get in touch and we will confirm what your car takes.

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: 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: How can the Focal TWU 1.5 be mounted?
A: There are four options: flush (recessed) mounting, surface mounting, in the factory location directly behind the original grille with the tweeter removed from its Focal support, or on the oriented (inclined) support.
Q: What frequency range does the TWU 1.5 cover?
A: It covers 4 kHz to 21 kHz, with an aluminium/magnesium inverted dome for clean, extended high frequencies.
Q: Which Focal systems is the TWU 1.5 designed for?
A: It is designed for tailor-made installations alongside existing kits from Focal's Universal range.
