Description
Real Bass at a Real Price...
Instead of focusing on dress-up parts like plastic magnet covers and multi-color logos, we decided to
use
bigger, 4-layer voice coils, better suspension designs, vented coil gaps and more powerful motor
systems
(You know... stuff that actually matters when it comes to making real bass).
Designed by the same team that develops JL Audio's legendary subwoofers, TMA subwoofers operate in
small sealed or ported enclosures and feature long excursion capability to make powerful, great-
sounding
bass in your vehicle.
Put them together with a TMA subwoofer amplifier and you have a combination that will put much more
expensive setups to shame.
That's what Total Performance is all about.
