1.5" Punch Pro SPL Tweeter Aluminium Diaphragm, Billet Machined Phase Plug, Die-Cast Aluminium Housing, Built-In 6dB/Octave Crossover. Sold Individually.
Product Overview
The Rockford Fosgate Punch Pro PP4-T is a 1.5" 4-Ohm tweeter engineered specifically for high SPL (Sound Pressure Level) applications competition car audio builds, high-output SPL-oriented systems, and any installation where tweeter sensitivity, power handling, and mechanical robustness take priority. It is sold as an individual unit, not a pair.
The PP4-T uses an aluminium diaphragm rather than the PEI or fabric dome materials used in standard Punch and Prime series tweeters producing a stiffer, lighter diaphragm with high sensitivity. A billet machined aluminium phase plug controls high-frequency dispersion from the diaphragm face, and a die-cast aluminium housing provides structural rigidity that pressed steel cannot match. A High Temp Kapton voice coil former is engineered to withstand the sustained high temperatures generated during high-SPL operation. A built-in 6dB/octave high-pass crossover is integrated into the unit.

Features & Benefits
Aluminium Diaphragm — The aluminium dome diaphragm is lighter and stiffer than soft dome or PEI materials — producing high sensitivity and a very fast, controlled high-frequency response suited to high SPL conditions where the tweeter must keep pace with high-output woofers and amplifiers. Aluminium domes produce a bright, forward, detailed treble character.
Billet Machined Aluminium Phase Plug — The phase plug is machined from solid billet aluminium rather than cast or stamped — sitting at the centre of the diaphragm to control the dispersion pattern of high-frequency output and reduce distortion caused by uncontrolled centre-cavity resonance. Billet machining produces a tighter dimensional tolerance than casting.
Die-Cast Aluminium Housing — The housing is die-cast aluminium rather than pressed steel or injection-moulded plastic — providing the structural rigidity and heat dissipation characteristics appropriate for a high-power, high-SPL tweeter operating in sustained competition conditions.
High Temp Kapton Voice Coil Former — Kapton (polyimide film) is the industry-standard high-temperature voice coil former material, chosen for its ability to maintain dimensional stability and mechanical integrity at the elevated temperatures produced by sustained high-power operation — a critical reliability requirement for SPL-oriented applications.
Built-In 6dB/Octave High-Pass Crossover — An integrated 6dB/octave high-pass crossover is built into the tweeter unit — filtering low-frequency content that could damage the 1.5" diaphragm. Crossover point (Hz) is not confirmed in the supplier data — pull from the official Rockford Fosgate PP4-T datasheet.
All-Metal Input Spring Terminal — Metal spring terminals provide a secure, vibration-resistant connection that does not corrode or loosen under the mechanical stress of high-SPL operation.
Oversized Motor Structure — An oversized motor provides greater magnetic flux for the voice coil — contributing to the high sensitivity and power handling characteristics of the PP4-T.
Sold Individually — The PP4-T is sold as a single unit. Two units must be purchased for a stereo left/right tweeter installation.

Frequently Asked Questions
Is the PP4-T sold as a pair?
No — the PP4-T is explicitly sold as an individual unit. Two units must be purchased separately for a stereo left/right installation.
What is an aluminium diaphragm tweeter and how does it differ from a PEI or soft dome?
An aluminium dome diaphragm is stiffer and lighter than PEI (rigid thermoplastic) or soft dome (fabric/silk) materials. This produces high sensitivity and fast, precise high-frequency response — well-suited to high SPL conditions where maximum output and impact are priorities. Aluminium domes typically have a bright, forward treble character that suits SPL and competition applications.
What is the confirmed power handling for the PP4-T?
The product description confirms 50W RMS. The product title states 100W, which most likely represents the peak power rating. The 50W RMS figure has been used throughout this listing as the confirmed sustained power rating. Confirm the full 50W RMS / 100W peak interpretation with Rockford Fosgate before publishing.
What does the billet machined aluminium phase plug do?
The phase plug sits at the centre of the tweeter diaphragm and controls the dispersion of high-frequency output — preventing uncontrolled resonance in the cavity behind the dome and improving the evenness of the tweeter's off-axis frequency response. Billet machining produces tighter dimensional tolerances than casting, contributing to more consistent acoustic performance.
What is a Kapton voice coil former?
Kapton is a polyimide film from DuPont, widely used as a voice coil former material in high-power speaker drivers. It maintains dimensional stability and mechanical integrity at the elevated temperatures generated during sustained high-power operation — important for a tweeter designed for high SPL applications where heat build-up can be significant.

1" Aluminium Dome Neodymium Tweeter Kit 75W RMS, Internal Mylar Phase Plug, Audiophile External Crossover with Protection and Bypass Resistor. 3-Level Attenuation.
Product Overview
The Rockford Fosgate Power T2T-S is a 1" aluminium dome tweeter kit rated at 75W RMS designed for listeners who prefer the bright, detailed, forward high-frequency character of an aluminium dome. The kit includes two tweeters with dedicated external crossovers, trim rings, and mounting hardware.
The aluminium dome is driven by a neodymium motor for high sensitivity and responsive transient performance. An internal Mylar phase plug sits behind the dome to control acoustic output from the cavity behind the diaphragm improving off-axis dispersion and reducing undesirable rear-wave resonances. The external audiophile-grade crossover uses 5% tolerance poly-capacitors and air-core inductors, and includes a built-in protection and bypass resistor a circuit that protects the tweeter from overdrive while ensuring the tweeter circuit remains active (never goes completely silent) when protection engages. Three levels of tweeter attenuation and on-axis/off-axis mounting configurations provide installation flexibility.

Features & Benefits
1" Aluminium Dome with Neodymium Motor — The aluminium dome diaphragm is stiff and light — producing a bright, highly detailed, and forward high-frequency character with fast transient response. The neodymium motor provides high magnetic flux in a compact assembly for high sensitivity.
Internal Mylar Phase Plug — The Mylar phase plug is positioned behind the dome inside the tweeter cavity. It controls the acoustic output from the rear of the dome — reducing cavity resonances and improving off-axis frequency response consistency. Mylar (polyimide film) is lightweight and dimensionally stable, avoiding acoustic interference with the dome itself.
External Audiophile Crossover with Built-In Protection and Bypass Resistor — The dedicated external crossover uses 5% tolerance poly-capacitors and air-core inductors for transparent, accurate frequency division. The built-in protection circuit safeguards the tweeter from excessive power input. The bypass resistor ensures that when protection engages, the tweeter circuit remains closed — the tweeter does not go silent but instead operates at a reduced, protected level for continuous audio output ("100% playtime").
3 Levels of Tweeter Attenuation — Three selectable attenuation settings allow the tweeter output to be adjusted relative to the woofer level — compensating for sensitivity differences and for tweeter positions closer to the listening position. Specific dB values are not confirmed in the supplier data — pull from the official Rockford Fosgate T2T-S datasheet.
On-Axis and Off-Axis Mounting — The tweeter supports both direct listening position placement (on-axis) and angled mounting for wider dispersion (off-axis) without additional hardware.
1-3/4" Recessed Hole Saw Mount — Standard 1-3/4" hole saw for a clean, flush installation in door panels, A-pillars, and dash trim.
Trim Rings Included — For a finished appearance at the tweeter mounting location.
Sold as a Pair — Two tweeters per kit.

Frequently Asked Questions
What is the internal Mylar phase plug and what does it do?
The phase plug is a lightweight Mylar (polyimide film) component positioned inside the tweeter cavity behind the aluminium dome. It controls the acoustic output from the rear of the dome, reducing cavity resonances that can cause uneven frequency response and improving the consistency of the tweeter's off-axis dispersion. The result is a more even frequency response across the listening area beyond the direct on-axis position.
What does the built-in protection and bypass resistor do?
The protection circuit monitors the signal level and activates when the tweeter receives excessive power input. The bypass resistor ensures that when protection engages, the tweeter circuit remains closed rather than going completely silent — the tweeter continues to play at a reduced, protected power level. Rockford Fosgate describes this as "100% playtime" — the tweeter maintains continuous audio output even during protection events.
What are the three levels of tweeter attenuation?
The three attenuation settings reduce the tweeter output level relative to the woofer by selectable amounts, compensating for the sensitivity difference between the drivers or for the tweeter being positioned closer to the listening position. Specific dB values for the three levels are not confirmed in the supplier data — confirm from the official Rockford Fosgate T2T-S datasheet.
What is the confirmed power handling for the T2T-S?
75W RMS per tweeter is confirmed. Impedance, sensitivity, and frequency response must be confirmed from the official Rockford Fosgate T2T-S datasheet.
What is the difference between aluminium dome and fabric dome tweeters?
An aluminium dome tweeter is stiff and light — producing a bright, detailed, forward high-frequency character with fast transient response. A fabric dome tweeter is softer — producing a warmer, smoother, more natural-sounding treble that is generally considered more forgiving for extended listening. Buyers who prefer detail and clarity tend to favour aluminium; buyers who prioritise warmth and long listening comfort tend to prefer fabric.
