Description
MMATS Pro Audio LS3 Series Subwoofers
LS3 steps above LS2 with 10, 12 and 15-inch sizes, each available in dual-2-ohm and dual-4-ohm configurations. The line is intended for proper sealed or ported subwoofer systems where more output is needed without moving into the larger high-power families.
Why we use LS3: it gives us flexible final impedance choices and enough size range to cover compact consoles, under-seat builds and larger trunk/cargo enclosures.
What matters before choosing one
- Pick size around usable enclosure volume—not just the biggest cone that physically fits.
- Pick D2 vs D4 around amplifier count and target final impedance.
- Ported and sealed alignments change the result dramatically; enclosure design should be decided before the sub is ordered.

BASS SYSTEM FIT
Where this fits in the build
The subwoofer is only one part of the bass system. Enclosure volume and alignment, final impedance, amplifier power, vehicle space and electrical support all affect the result.
Plan aroundChoose the bass target and usable space first.
Match itMatch the enclosure to the driver instead of treating the box as an afterthought.
Finish itMatch final load, amplifier and electrical support to the complete bass plan.
