Suitable for both sealed and ported enclosures, it reproduces low frequencies with tight control and exceptional detail.

About the Morel ULTIMO PRO 124D
From our tech experts at CEN
A Morel Ultimo 12 inch subwoofer, 4 ohm, handling 1000w RMS.
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.
