Description
The Citronic ML3-12LF-3504 is a 12-inch subwoofer driver built to handle the low frequency content in sub cabinets. It carries 350W RMS power handling, with a maximum of 700W, so it copes with the demands of bass reproduction when paired with satellite or array speakers. The 4 ohm impedance and 95dB sensitivity make it a practical choice for anyone building or repairing a sub enclosure.
This driver uses a reinforced paper cone on a steel basket, which keeps the moving parts stable under load. A 50mm (2") voice coil sits behind a 1.28kg ceramic magnet, and the frequency response runs from 40Hz up to 2kHz. That range keeps the focus on the low end, where a subwoofer earns its place. The unit measures 310mm across and 160mm deep, and weighs 6.0kg, so it fits standard 12" cabinet cut-outs.
We supply the ML3-12LF-3504 as a direct replacement for the Monolith mk3 sub unit, which makes it a straightforward swap if you already run that system. Whether you are servicing an existing rig or fitting a fresh driver into a new build, the fixings and dimensions line up with the original part. Note that in the US a subwoofer driver like this is often called a woofer or bass driver, but the fitment and figures are the same. It is a working component rather than a finished speaker, so plan your cabinet and wiring to match the 4 ohm load.

Frequently Asked
What is the power handling of this driver?
It handles 350W RMS with a maximum rating of 700W, suited to low frequency use in sub cabinets.
What impedance is the ML3-12LF-3504?
The driver is 4 ohms. Make sure your amplifier is happy driving a 4 ohm load before wiring it in.
Will this fit the Monolith mk3 sub?
Yes. It is a direct replacement for the Monolith mk3 sub unit, so the dimensions and fixings match the original.
What size cabinet cut-out does it need?
The driver measures 310mm across and 160mm deep, matching standard 12-inch subwoofer cut-outs.
What is the frequency response?
It runs from 40Hz to 2kHz, keeping the output focused on the low frequency range.
Does it come as a complete speaker?
No, this is a driver component only. You will need a suitable sub cabinet and wiring to use it.
