Rockford Fosgate 1" Mylar Dome Tweeter Kit (Pair) Prime R1T-S — 40W RMS, Integrated Crossovers

The Rockford Fosgate Prime R1T-S is a pair of 1" mylar-dome tweeters with integrated crossovers that add clear, low-distortion high frequencies to your car audio system.

Engineered by Rockford Fosgate, the Prime R1T-S tweeter kit provides a simple, effective way to enhance treble detail and improve soundstage clarity without replacing your entire system. The compact 1" mylar dome drivers use a 0.5" voice coil and come with built-in high-pass crossovers, flexible mounting options and dependable power handling so you can tune the top end with confidence.

How will these tweeters change the high-frequency detail in my car?

The R1T-S focuses on reproducing upper frequencies with low distortion for a more open, articulate sound. Mylar domes offer controlled response that highlights vocals, cymbals, and ambient detail without sounding brittle.

• 1" mylar dome for natural high-frequency character
• 0.5" voice coil for responsive transient reproduction
• Integrated high-pass crossovers to protect drivers and balance tonal output

What power and impedance should I expect, and what system pairs well?

Each tweeter pair is rated at 4 ohms with 40 Watts RMS (80 Watts peak), making them suitable for most factory and aftermarket head units or compact amplifiers. They are ideal as an add-on to existing component systems or to replace worn factory tweeters for clearer highs.

• 4-Ohm nominal impedance for compatibility with common car audio setups
• 40W RMS / 80W peak power handling for reliable daily use
• Works well with small amplifiers or powered head unit channels

How do I mount and install the Prime R1T-S tweeters?

The kit includes mounting hardware that supports flush, surface, and angled installations so you can match the tweeter placement to your vehicle’s interior acoustics. Compact mounting depths let you fit them into tight dash, sail panel, or pillar locations without major modification.

• Tweeter mounting depth: 0.76" flush; 1.06" surface/angle
• Multiple mounting options for precise aiming and imaging
• Plug-and-play wiring with included crossovers simplifies installation

What build quality and warranty come with these tweeters?

Rockford Fosgate backs the R1T-S with their recognized manufacturing standards and a one-year warranty for peace of mind. The tweeters are constructed to deliver consistent performance and low distortion over regular use.

• Rockford Fosgate engineering and rugged construction
• Low-distortion mylar material for long-term clarity
• 1-year limited warranty from the manufacturer

Who is this for? The Prime R1T-S tweeter kit is aimed at drivers who want a quick, affordable way to improve the clarity and detail of their car audio system without overhauling speakers or adding large amplifiers. It's a solid choice for restoring crisp highs to a factory system, upgrading older setups, or fine-tuning imaging in compact aftermarket installations.
