Are you looking to upgrade the sound of your car’s audio system? Thanks to Rockford Fosgate’s new T1S1-12 shallow subwoofer, you no longer have to sacrifice sound quality for bass.
Rockford Fosgate T1S1-12 shallow mount subwoofer is an excellent choice for anyone looking to add powerful and deep bass tones to their car audio system. It’s easy to install and use and can handle up to 600 watts RMS. The sleek and modern design is a plus, and the subwoofer works well with various amplifier and crossover combinations.
Tip: You can get this excellent subwoofer built into factory Rockford Fosgate Enclosure (link to Amazon), or if you want a customized box specifically for your car, you can have it designed in CarAudioFabrication.
Design
The Rockford Fosgate T1S1-12 subwoofer is designed for those who want a big sound in a small package.
The subwoofer’s carbon fiber/PMI/glass fiber cone with aluminum dust cap and injection molded foam surround give it a sleek and modern look.
The patent-pending motor technology and Vertical Attach Surround Technique (VAST) make this subwoofer unique and stand out from the competition.
The VAST technology allows the subwoofer to have a cone area larger than the typical shallow subwoofers, resulting in a fatter bass sound.
Additionally, the subwoofer’s neodymium motor structure with high-strength magnets helps to minimize the mounting depth, which makes it a great option for those who don’t have a lot of space in their vehicle.
Functionality
The T1S1-12 subwoofer is a 12″ 1-ohm component subwoofer that can handle up to 600 watts RMS (1200 watts peak) power.
This sub’s 1-ohm impedance makes it a great candidate for multiple sub setups or getting max power from high-performance mono amps.
This subwoofer can produce low-frequency sound in the range of 27-250 Hz. This range is generally considered the deep bass range, which is not often achievable even by standard size subwoofers.
The sensitivity of 85 dB means that the subwoofer can efficiently convert power into sound, which results in a louder and clearer sound, but it requires a strong amplifier with at least 500 W RMS.
Features
#1. 12″ 1-ohm component subwoofer
The 12″ size of the subwoofer is the largest size for shallow subwoofers, and the 1-ohm impedance is suitable for high-performance mono amps.
#2. Carbon fiber/PMI/glass fiber cone with aluminum dust cap
Using carbon fiber and other materials in the cone construction gives the subwoofer a stiff and lightweight design, resulting in better sound quality.
In addition, the aluminum dust cap adds strength to the cone and helps to protect the subwoofer from damage.
#3. Injection molded foam surround
The foam surround provides a flexible and durable support for the cone, which allows the subwoofer to produce a more accurate and consistent sound.
#4. Vertical Attach Surround Technique (VAST) increases cone area
The VAST technology increases the cone area, which results in a fatter bass sound.
#5. Patent-pending motor technology
The patent-pending motor technology allows the subwoofer to have a neodymium motor structure with high-strength magnets, which helps to minimize the mounting depth.
#6. Handles up to 600 watts RMS (1200 watts peak) power:
The subwoofer can handle a high amount of power, which means that it can produce a loud and powerful sound.
#7. Frequency response 27-250 Hz:
Playing at 27 Hz allows this sub to make lower tones than most standard-size subwoofers.
#8. Sensitivity 85 dB
The subwoofer can efficiently convert power into sound, resulting in a louder and stronger bass.
#9. Top mount depth: 3″
This is a fantastic achievement for such a large subwoofer, a shallow mounting depth of only 3″ makes it an excellent option for those who don’t have a lot of space in their vehicle.
#10 box volume
The subwoofer can be used in a sealed box with a volume of 1 cubic foot or a ported box with 2 cubic feet.
Using a ported box will allow the subwoofer to produce a deeper and more accurate bass sound.
Ease of Use
Depending on your car, the T1S1-12 subwoofer is easy to install but may require spacers or wedge spacers. I did not have to use any when testing it, but it depends on your exact location.
The subwoofer should be broken in slowly for the best results, and some recommend even two months to get the full effect and performance.
It is recommended to use a high-quality or custom box, and this sub is not designed to be mounted on an infinite baffle (free air), and for the strongest bass, I recommend using a ported box.
Installation is straightforward, and the subwoofer comes with detailed instructions that will guide you through the installation process.
