MAXIMO ULTRA 402 MKII
The Maximo Ultra marks a significant step forward in entry-level speaker performance.
2-WAY COAXIAL SPEAKER SET
The Maximo Ultra MKII coaxial speakers deliver strong sound quality at an affordable price. Engineered for drop-in fitting to original factory locations, the coaxial design is carefully tuned for dynamic sound, excellent off-axis dispersion, resolution, and crisp detail — helping to overcome the acoustic limitations of factory speaker positions.
DMM MOTOR
Morel's double drive system generates more magnetic energy than a single magnet of similar size, increasing efficiency and dynamic range. The secondary magnet is fixed above the top plate in the motor, controlling stray magnetic flux to produce a more focused, effectively shielded magnetic field.
EVC MOTOR
EVC™ technology uses large-diameter voice coils for improved heat dissipation, power handling, and linearity. The motor system sits within the voice coil, eliminating stray magnetic flux by directing all magnetic energy where it's needed. The result is a magnetically shielded, efficient, and compact architecture.
PAPER CONE
Morel's paper composite cones are ultra-lightweight, making them an excellent match for drivers using smaller motors and voice coils, while retaining paper's well-established acoustic properties.

About the Morel Maximo Ultra 402 MKII
From our tech experts at CEN
Morel Maximo Ultra 4 inch coaxial speakers, with the tweeter mounted in the centre of the woofer, rated at 80w RMS.
Who it suits
Drivers replacing tired factory speakers who want a clear improvement without relocating tweeters.
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 and tweeter placement change the result as much as the driver does, and speakers at this level deserve an amplifier. 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.
Q: What is the mounting depth of the Maximo Ultra 402 MKII?
A: The mounting depth is 5.2cm.
Q: What frequency range do the Maximo Ultra 402 MKII cover?
A: The frequency response is 75Hz to 20kHz, with a sensitivity of 87.5dB (2.83V/1m).

A: The Maximo Ultra 402 MKII speakers, grilles, installation instructions and a Morel window sticker.
