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. For a larger midrange option from ESB Audio, see the ESB 4.165 4000 Series 6.5 inch component mid woofer.

About the ESB Audio 3.90
From our tech experts at CEN
The ESB 3.90 is a pair of 3.5 inch (90mm) cone midrange drivers from ESB's Tremila Series, not a component set with tweeters. Each handles 60w RMS and 120w transient at 4 ohm, with 91.5 dB sensitivity and a 150 Hz to 7 kHz range. It uses a waterproofed pressed paper cone, Perbunan rubber surround and a fibreglass-reinforced ABS basket.
Who it suits
Builders of 3-way front stages who want a dedicated midrange between the door woofer and the tweeter. It is the midrange used in the 3.6K3 3-way system, alongside the 3.165 mid-woofer.
Our tech experts advise
A midrange like this needs a crossover or processor to keep it between roughly its 150 Hz and 7 kHz limits. Mount it in the dash or upper door, close to the tweeter, for a coherent sound. 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: 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 frequency range does the ESB 3.90 cover?
A: Its frequency response is 150 Hz to 7 kHz, so it is intended as a dedicated midrange in a 3-way or active system.
Q: How much power can the ESB 3.90 handle?
A: It is rated at 60W RMS (nominal) and 120W transient, with a 4 ohm impedance and 91.5 dB sensitivity (2.83V/1m).
