Our take on the MTX TR4512-04

by Dominic Devito
MTX

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

MTX's TR45 Series subwoofers bring swagger back to the bass game — they sport killer graphics to match their impressive low-end output, so you can show them off for their sound and their looks. You won't have to empty your wallet to keep your trunk or cargo area full of bass with these hard-driving subs.

The TR4512-04 12" subwoofer features a tough-as-nails polypropylene cone and nitrile-butylene rubber surround that deliver pounding performance and distortion-free bass at moderate power levels. This workhorse sub works well in either a ported or sealed enclosure.

Features

Polypropylene Cone: The woofer features a silver polypropylene cone with a raised MTX Audio and tribal design logo. Polypropylene is lightweight yet durable and offers efficient, dependable bass response.

High Roll NBR Surround: The woofer features a stitched high roll Nitrile-Butylene Rubber surround which uses FEA optimized roll geometry to maximize excursion without sacrificing cone surface area.

Voice Coil: The voice coil is wound on a high-temperature former to promote high power handling.

Asymmetrical Linear Drive System (ALDS): The Asymmetrical Linear Drive System consists of a flat, progressive spider that improves suspension and an extended vented pole piece that smoothes out the cone's linear motion. The result is high output and low distortion.

Spider Plateau Venting: Heat from the voice coil is vented through metal-mesh covered vents that surround the back of the spider.

Enclosure Compatibility

Recommended Sealed Box Volume: MTX recommends mounting this woofer in a sealed enclosure made out of 3/4" MDF with an internal volume of 1.25 cu/ft.

Recommended Vented Box Volume: MTX recommends a ported enclosure made out of 3/4" MDF with an internal volume of 2.00 cu/ft using a 2" wide x 14" tall slot port that is 16.75" long.

MTX TR4512-04

Written By Dillon, Montana on Saturday, August 09, 2008
Crutchfield Customer Review (What's this?)
 
These subs can pound if you get them set up correctly. If you are placing them in a ported box i would suggest that you buy two amplifiers instead of hooking them parallel to a multi-channel amp. they push against each other and the amp sends the power to the sub with the least resistance. all in all for the price these subs are a good buy.
