Description
MMATS Pro Audio AS Shallow Subwoofers
The AS Series is MMATS' shallow-depth subwoofer option for installations where enclosure depth is the hard limit. It is available in 10-inch and 12-inch dual-4-ohm versions.
Why we use it: truck-seat, side-panel and other space-limited builds often need real low-frequency capability without giving up useful interior room. AS lets us preserve packaging space without dropping all the way to a lightweight factory-replacement woofer.
Tradeoffs
- A shallow subwoofer still needs the correct enclosure volume and tuning.
- It is not the right choice when maximum displacement/SPL is the only goal; a deeper high-excursion driver has more room for motor and suspension.
- Final impedance and amplifier power should be planned before deciding between single or multiple subs.
In-store / quote-only product. SMS Car Audio designs the enclosure and amplifier match around the available depth and bass goal.
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.
