3.6K2X 2-Way Speaker System with 1"/25 mm Tweeter + Cx
3.165 6.5"/165 mm Mid-Woofer
Fibreglass-reinforced ABS basket engineered for maximum torsional rigidity while minimising resistance to air passage.
Pressed paper cone with waterproof treatment. Paper cones offer an ideal balance of lightness, stiffness and vibration damping.
High-damping, single-wave rubber surround using Perbunan® rubber, which is more thermally stable than standard rubber.
25 mm voice coil on an aluminium support with double-layer winding of copper wire with an aluminium core. High-grade ferrite magnet for significantly higher performance than standard magnets.
3.25 1"/25 mm Dome Tweeter
Silk-impregnated thin fabric dome diaphragm for smooth sound. The outer suspension is coated with a high-loss damping material to eliminate edge vibration and resonance. The extremely low-mass dome resists mechanical deformation and delivers a smooth, linear, extended response.
25 mm voice coil on an aluminium support wound with very light copper-coated aluminium wire. The voice coil is ventilated and damped with ferrofluid oil.
ESB's SVS ventilation design provides optimal voice coil cooling and prevents air compression behind the dome.
Neodymium N42 magnet, optimised via computer simulation for improved efficiency and linearity.

About the ESB Audio 3.6K2X
From our tech experts at CEN
The ESB 3.6K2X is a 2-way component set from the Tremila Series. It pairs the 3.165 6.5 inch mid-woofer, rated at 120w RMS, with the 3.25 1 inch silk dome tweeter at 90w RMS, both 4 ohm. The mid-woofer uses a treated paper cone and Perbunan rubber surround in a fibreglass-reinforced basket.
Who it suits
Drivers who want a proper front stage from an Italian sound-quality brand without going to three ways. It is the simpler fit of the two Tremila sets. Step up to the 3.6K3 if you want a dedicated 3.5 inch midrange and the larger 1.1 inch tweeter.
Our tech experts advise
Sensitivity is around 91.5 dB for the mid-woofer and 92 dB for the tweeter, so they will run from a head unit but come alive with an amplifier. Mount the tweeters high on the dash or pillar and aim them towards the listener. Door treatment matters as much as the speaker. Get in touch for fitting. 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.
Q: Which drivers are in the ESB 3.6K2X?
A: The set contains ESB 3.165 6.5 inch (165 mm) mid-woofers and ESB 3.25 1 inch (25 mm) silk dome tweeters.
Q: What is the power rating of the ESB 3.6K2X?
A: The 3.165 mid-woofers handle 120W RMS (240W transient) and the 3.25 tweeters handle 90W RMS (180W transient), both at 4 ohms.
