Description


Rockford Fosgate brand icon

Authorized dealer

The Rockford Fosgate Power series is the finest in audiophile grade sound. Since the original introduction of the Power series, Rockford raised the bar for high-end car audio products. The most recent Power speakers integrate unique Rockford Fosgate technology and advanced engineering that result in the best Power sound to date. The patent pending VAST surround provides a larger surface area for the cone. Vast, or Vertical Attach Surround Technique gives about 25% more effect radiating cone, which improves both the efficiency and maximum output capabilities. The new flexfit basket utilizes holes and slots as opposed to the traditional speaker mounting holes. This gives the speakers an easier fit into OEM opening, as well as a secure fit.

To separate the mid and high frequencies, Rockford uses an Integrated Concealed Crossover, or an ICC. The ICC hides in the basket of the woofer and is not visible. The result is a simpler installation, while preserving incredible sound. The full-range coaxial speakers also feature an offset mounted tweeter. The Offset Cantilever Coaxial Mounted Tweeter removes any frequency response abnormalities due to acoustic reflection between the woofer and the tweeter.

Great acoustic qualities

The T142 as nearly all 4 inch speakers does not have much bass but its volume handling capabilities are wonderful. Even with heavy bass music the speaker retains its sound quality under loud volume. It has incredibly accurate and clean sound however inevitably the deep bass lacks due to size. It does punch though on hard quick bass just does not reverberate like a 6 inch speaker would. I do recommend! The high end of the sound spectrum is superb.

more than 4s

Owning a volvo 240 ive experimented with alot of 4's and some 5's. These are the best ive had, but ive never spent $100 on 4's before. still cant expect bass. They were too deep to fit in my door without hittin my windows so there's some mild custom work.

Keeps Up!

The following review is for a previous version (T142C).

This is a good little 4" speaker they're in the back of my camaro sitting next to 2 P3s. I'm waiting on a four channel amp to replace the one running my 4 front speakers so I faded all the sound to the rear of my vehicle. It's just these and the P3s right now and they are doing an alright job keeping up considering they're running off the HU and the P3s are getting 1500rms from an Autotek mean machine 1500. Granted I turned the bass way way down but when My MB Quart PVIs and the new Rockford Power 6.5s get there amp it will be a well balanced setup. Would def recommend these 4s there cheap and you could amp them just don't have to.

really hits the highs

The following review is for a previous version (T142C).

I replace the stock 4" speakers in my camaro with these. really made a difference and the highs that it hit sounded amazing. the only downfall to all 4" speakers is they can't handle that much power but sounded great anyway!
