About the MTX SS5

Signed, sealed, delivered

SS5 woofer

The SS5's 5-1/4" woofer, ready to kick out the jams.

MTX's built their Signature Series speakers to give you great sound. Period. The SS5 component system begins with the 5-1/4" woofer, which features a glass fiber/paper cone housed in a non-resonant cast aluminum basket for maximum accuracy. The cone's stiffness-to-weight ratio allows the woofers to deliver strong output, even when you're using a smaller amp or your car stereo's built-in power. You can mount the system's water-resistant teteron tweeters inside door panels or pillars without worry about moisture damage.    

Crossing over

MTX designed the system's 2-way crossover for ease of installation, with pre-wired connections for the woofer and tweeter. You can choose between two tweeter levels (flat and -3 dB) so the highs will be balanced with the rest of your music. The crossover's small size allows a variety of mounting options. You can use screws or zip ties to mount the crossover, or you'll also find a threaded rear insert which allows blind mounting inside the door panel – out of sight and out of the way.

The SS5 system offers high-fidelity sound reproduction, with real-world features that make installation much easier. Hear the greater clarity and definition that these quality speakers can bring to your vehicle.

Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

Product Research


Crossovers: The input and output wires (12") are attached to the crossovers. The output wires are terminated with quick slides, so they easily plug into the woofers and tweeters. There are two tweeter output options, flat and -3 dB. The crossovers are round, approximately 3-3/4" diameter and 1-3/8" tall. The crossover slope is 12 dB/octave and the crossover point is 2 kHz. While not waterproof, the crossovers are in closed casings, so mounting them in the doors should not present any moisture problems.

Woofers: The combination paper and glass fiber cone has a high stiffness to weight ratio, maintaining a detailed output and keeping the damping characteristics of the paper.

Tweeters: The tweeters are 30mm (1-3/16") Teteron soft domes. They can be flush mounted, angled mounted (semi-flush), or surface mounted.
