About the Hertz ML 2500.3
From our tech experts at CEN
A Mille Legend series 10 inch subwoofer, 4 ohm, handling 700w RMS.
Who it suits
Drivers building a system where the bass does real work rather than filling in behind the speakers. The Mille Legend line is Hertz at its most serious, and deserves an amplifier and enclosure to match.
Our tech experts advise
A subwoofer is only as good as its enclosure and the amplifier driving it: box volume and port tuning decide what you actually hear, and impedance decides how it should be wired to your amplifier. 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.

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: What box does the ML 2500.3 need?
A: Its parameters are optimised for a sealed enclosure of 17 to 25 litres.
Q: Does the ML 2500.3 come with a grille?
A: No grille is listed in the box. The MG 250.3 steel mesh grille and the MLG 2500.3 die-cast aluminium grille are available separately.
