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.
