When defining realism in a car audio system, frequency response is one of the most crucial aspects. We want the midbass, midrange, and high-frequency information to be reproduced at similar levels. When done correctly, voices and instruments sound like they did in the mastering room at the recording studio, and not like a clock radio or smartphone. A key factor in delivering this sense of realism is to use high-quality tweeters with your midrange speakers. In that regard, Rockford Fosgate has the perfect solution with its Power Series T1T-S 1-inch tweeter set. Let’s check them out!
Rockford Fosgate T1T-S Design
The T1T-S tweeter set includes a pair of 1-inch audiophile-grade fabric dome tweeters, passive crossover networks, mounting rings, and installation hardware. Rockford Fosgate rates the set to continuously handle an equivalent of 75 watts of power. Maximum power handling is rated at 150 watts, and efficiency is specified as 90 dB SPL 1W/1M. Finally, the tweeters have a nominal impedance of four ohms. Like all Rockford Fosgate speakers, these ratings comply with the ANSI/CTA-2031 Automotive Loudspeaker standard.
The tweeter diaphragms are made from treated fabric. The balance of low mass from the fabric and damping from the treatment helps ensure linear operation up to extremely high frequencies without unwanted resonance. Undamped designs can cause resonance, which many people find harsh. Rockford Fosgate claims an upper-frequency limit of 22 kHz, which is very good. The design has a resonant frequency (Fs) of 1.8 kHz, which is nice and low for a 1-inch tweeter. An integrated neodymium magnet drives the tweeters. Neodymium provides a much stronger magnetic field than ferrite magnets, so you get more efficiency and output from a compact design. These are the same drivers you’d find in the T-162S and T-1652S two-way component speaker sets.
Passive Crossover Networks
The Rockford Fosgate T1T-S set includes a pair of passive crossover networks designed with a 3 kHz cutoff frequency and a third-order -18dB/Octave attenuation slope. Your installer has input connection options to adjust the output sensitivity to 0, -2, or -4 dB to ensure the tweeters blend well with the midrange speakers. On the output side, on- and off-axis connection options subtly alter the signal phase around the crossover point to improve the system’s coherence further. The crossovers use high-tolerance polypropylene capacitors and air-core inductors for good power handling. The circuit also includes a Positive Temperature Coefficient (PTC) thermistor. Should you drive the amp you are using into clipping, the PTC will limit the power going to the tweeters. Unlike fuses, the PTC resets itself to normal operating conditions once everything cools off.
Premium Mounting Hardware
At a time when many of the most expensive tweeters on the market require mounting with hot glue or backstraps, it’s refreshing that Rockford Fosgate provides real metal mounting hardware. You can mount the tweeters either flush or on the surface using the Discreet Dual Clamp (DDC) hardware. An installer might also create a custom mount to position the tweeter behind an OE grille in your car or truck.
Another key feature of the T1T-S set is the inclusion of a mesh protective grille with each tweeter. Without protection, many expensive tweeters have suffered damage, making this a welcome addition.
Upgrade Your Car Audio System with Rockford Fosgate T1T-S Tweeters
Whether you want to add clarity to a dull factory-installed audio system, need a solution to keep up with a few woofers in each of your vehicle’s doors, or are putting together a clean and classy system, the Rockford Fosgate T1T-S tweeter set is a great choice. They sound great and include premium mounting solutions that ensure they function reliably for years without any headaches.
