Vertical Attach Surround Technique (VAST) Technology

Rockford Fosgate uses this technology as its trademark to produce speakers with mind-blowing sound quality. The VAST technology creates an effective radiating cone using a state-of-the-art design and manufacturing technique. This eliminates the massive flat-glue surface/landing and expands the surround cone area by 25%.

In addition, the VAST tech improves the maximum output and nominal efficiency by shifting how the surround connects to the subwoofer’s or speaker’s basket.

Simply put, every bit of your speaker’s surface is used to give the speakers a taste of power and attitude to achieve optimum performance.

Santoprene TPV Rubber Surround

Santoprene, also called Santoprene TPV, comes from the thermoplastic elastomer group of polymers. However, it shares more features with thermoplastic vulcanizates or vulcanized rubber.

While it resembles a foam surround, the Santoprene TPV lasts longer because it can handle punchy sounds from the P1650 speakers. Also, the Santoprene rubber speaker surround minimizes sound distortion and enhances mid-bass performance.

FlexFit 2 Basket Mounting

The Rockford Fosgate P1650 speaker offers a FlexFit 2 mounting which is easily compatible with European, imported, or US vehicles. So, don’t worry about fitting this speaker in your Volkswagen, Vauxhall, or Citroen model because the “European Basket” has got you covered.

Also, the slots on the outermost edge of the P1650 basket allow easier installation of the speaker.

Injection-Molded Mineral-Filled Polypropylene Cone

Over the years, cones have experienced a drastic improvement, with the Polypropylene (PP) cones being one of the latest advancements. Injection-molded mineral-filled polypropylene cones have gained popularity in home-theater audio systems because they have appealing features such as stability, consistency, and reduced distortion.

The Rockford Fosgate P1650, therefore, delivers crisp and top-notch sound quality. If humidity is an issue in your automobile, we’ve got good news for you. The Injection-molded mineral-filled polypropylene cone makes this punch speaker resistant to moisture absorption that would otherwise affect the speaker’s performance.

0.75 Inch Treated PEI Dome Tweeter

The Rockford Fosgate P1650 has a high-frequency response of up to 20000 Hz, which is perfectly handled by the PEI dome tweeters.

So how is it done?

Highs coming from the speaker have directional sound waves instead of the much-needed smooth dispersed sound waves. Consequently, the dome tweeter’s shape comes into play to provide an improved and much wider sound dispersion pattern to give you a larger sound area while setting up your sound system.

Additionally, the PEI dome tweeters make the P1650 speakers lightweight and cost-friendly. Lastly, if ambient noise is a thing of concern, worry not because the PEI dome tweeter will deliver bright and accurate sounds that cancel out any sonic interference in your car.

Power and Performance

Having an impeccable sound quality and mind-blowing performance- heavily relies on the wattage of a speaker. This punchy series speaker is designed to handle a maximum power of 110 watts with noise level of 88 decibels for excellent performance and minimum distortion.

Eased Mounting and Fixing

As previously hinted, the Fosgate P1650 speakers can be easily fitted and mounted in numerous car models. The included car speaker brackets make mounting of this speaker effortless. Also, its grille allows the speaker to snugly fit into Gen-3 P2 and P3 trim rings and woofers. Therefore, your speaker stays protected against the cone and surround damage.


  • Enhanced performance for lows, mids, and highs
  • They minimize sound distortion and sonic Interference.
