3.90
3.5"/90 mm Cone Midrange
A 60W RMS midrange driver built for accuracy, using quality materials throughout to keep distortion low and output clean.
The ABS basket is reinforced with fibreglass, giving it strong torsional rigidity while allowing maximum airflow through the basket walls.
The pressed paper cone uses a waterproof treatment. Paper cones are well regarded for their ideal balance of low weight, stiffness, and natural damping — all of which help reduce unwanted vibration and distortion.
The twin symmetrical wave rubber surround uses Perbunan® rubber, which stays stable across a wider temperature range than standard rubber. The 20 mm voice coil is wound on an aluminium former using a double-layer copper and aluminium core winding.
A high-grade ferrite magnet delivers stronger magnetic performance than standard magnets, helping to improve overall driver efficiency.

About the ESB Audio 3.90
From our tech experts at CEN
ESB Tremila Series 3.5 inch component speakers, with separate tweeters for mounting where you will actually hear them, rated at 60w RMS.
Who it suits
Drivers building a proper front stage who care about staging and detail. ESB is bought by people who have usually owned a decent system already.
Our tech experts advise
Sizes, adapter rings and harnesses vary by vehicle, year and trim, so we confirm what your car takes before ordering rather than guessing. Door treatment matters as much as the speaker, and these repay both amplification and tuning. 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.
