Ultimo TI 10 inch (250 mm) Subwoofer – 1000 W at 4 Ohm
The Ultimo Titanium is Morel's current flagship subwoofer range, building on the musicality and high power handling that the original Ultimo series was known for.
At the heart of the Ultimo TI 104 is a titanium voice coil former — exceptionally stiff and lightweight — which improves transient response, lowers distortion and increases power handling compared to the previous generation.
A copper shorting ring reduces distortion and flattens impedance response. This is particularly significant in subwoofers, where distortion levels are inherently high.
The driver shares key technology with the original Ultimo: a 5.1 inch Hexatech™ External Voice Coil (EVC™), the DMM™ (Dual Magnet Motor) design achieving over 90% efficiency, and PFS™ (Progression Field Symmetry) spider/surround technology that stiffens the spider as excursion increases for maximum linearity and flat response.
The titanium former and continued parameter optimisation allow the Ultimo TI to work efficiently in smaller enclosures than its predecessors, while improving overall performance.

About the Morel ULTIMO TI 102
From our tech experts at CEN
A Morel Ultimo Ti 10 inch subwoofer, 4 ohm.
Who it suits
Drivers building a system where the bass has to keep up with a good front stage rather than simply be loud. The Ultimo line is Morel at its most serious and deserves a properly built enclosure.
Our tech experts advise
A subwoofer is only as good as its enclosure and the amplifier driving it: box volume and tuning decide what you actually hear, and impedance decides how it should be wired. We build enclosures to suit the vehicle at our Beeston workshop. 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: Do I need an amplifier for this subwoofer?
A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.
Q: What size enclosure does this subwoofer need?
A: The recommended enclosure volume is listed in the Specification tab where the manufacturer provides it. As a rule, sealed enclosures give tighter, more accurate bass while ported enclosures deliver more output. Contact CEN if you would like a recommendation for your build.
Q: What does RMS power mean?
A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.
Q: Sealed or ported enclosure - which should I choose?
A: Sealed boxes are compact and produce tight, controlled bass suited to sound quality builds. Ported boxes are larger and produce more output at low frequencies, suited to those who want maximum impact. Either works well when built to the recommended volume.
Q: Can CEN build or supply an enclosure and fit everything?
A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.
Q: Is the Morel Ultimo TI 104 a single or dual voice coil subwoofer?
A: It has a single 4 ohm voice coil.
Q: How much power does the Ultimo TI 104 handle?
A: It is rated at 1000 W RMS and 3000 W peak.
Q: What mounting depth does the Ultimo TI 104 need?
A: Mounting depth is 13.4 cm with a mounting hole diameter of 23.2 cm. A grille is included.
