Frequently Asked Questions about Power T1S2-12 / T1S1-12

What are the main features of the Power T1S2-12 Subwoofer?

The Power T1S2-12 from Rockford Fosgate is a 12-inch flat Subwoofer. The cone material, made from a blend of carbon fiber, PMI, and fiberglass, ensures high stability and low distortion. The aluminum dust cap efficiently protects the interior of the Subwoofer. The injection-molded foam surround with VAST™ allows for a larger effective diaphragm area. Additionally, the Subwoofer features two progressive Nomex spiders with integrated connection wires that can support a high power handling of 600 watts RMS. The aluminum die-cast frame with cooling fins provides better heat dissipation and increased durability.

What are the technical specifications of the Power T1S1-12 Subwoofer?

The Power T1S1-12 is also a 12-inch flat Subwoofer from Rockford Fosgate. It has a power handling of 600 watts RMS and a maximum power handling of 1200 watts. With a mounting depth of 76.5 mm, it is compact and suitable for tight installation conditions. The nominal impedance is 1 ohm, and it uses a single voice coil. The voice coil diameter is 3 inches, and the magnet weighs 0.41 kg. The Sd value is 560 cm², and the Vas value is 32.4 liters, making it optimized for a sealed enclosure volume of 31.1 liters.

How does the Power T1S2-12 variant differ from the T1S1-12?

The main differences between the Power T1S2-12 and T1S1-12 Subwoofers from Rockford Fosgate lie in the nominal impedance and the type of voice coil. The T1S2-12 has a nominal impedance of 2 ohms, while the T1S1-12 has a nominal impedance of 1 ohm. Both Subwoofers have a single voice coil, but their electrical values differ. The T1S2-12 has a Re of 1.7 ohms, and the T1S1-12 has a Re of 0.9 ohms. Despite these differences, both Subwoofers have the same power handling of 600 watts RMS and a mounting depth of 76.5 mm.

For which types of enclosures is the Power T1S2-12 optimized?

The Power T1S2-12 Subwoofer from Rockford Fosgate is specifically optimized for use in sealed and bass reflex enclosures. A volume of 31.1 liters is recommended for a sealed enclosure to ensure the best possible performance and sound quality. For a bass reflex enclosure, a volume of 56.6 liters is advisable. These optimized volume values ensure that the Subwoofer operates efficiently and delivers deep and fairly voluminous bass sounds in both sealed and bass reflex enclosures. The Subwoofer particularly shows its strength in these configurations.

How does the motor technology of the Power T1S1-12 contribute to performance?

The proprietary split-yoke pass-through motor technology used by Rockford Fosgate in the Power T1S1-12 flat Subwoofer is patented and a crucial feature for the performance of this Subwoofer. It ensures efficient use of the high-energy neodymium motor, which is characterized by high thermal stability. Together with the integrated copper cap short-circuit ring (IDHS), this design minimizes distortion and increases performance. The high-temperature resistant motor structure also ensures sustained sound fidelity and functionality even at high power levels, which is particularly advantageous in demanding environments.

What frequency and Q factor points does the Power T1S2-12 have?

The Power T1S2-12 Subwoofer has the following acoustic characteristics: The resonance frequency (Fs) is 37 Hz, allowing it to efficiently reproduce deep bass tones. The total Q factor (Qts) is 1.06, with a mechanical Q factor (Qms) of 11.22 and an electrical Q factor (Qes) of 1.17. These Q values significantly influence the behavior of the Subwoofer in both sealed and bass reflex enclosures. A Vas of 32.4 liters and a maximum linear excursion (Xmax) of 15 mm contribute to the Subwoofer's ability to ensure precise sound reproduction even at high levels.

What features does the cone of the Power T1S1-12 have?

The Power T1S1-12 Subwoofer is equipped with an innovative cone design. The cone is made from a carbon fiber/PMI/glass fiber mixture that offers excellent strength and lightness. This material combination reduces distortion and ensures that the diaphragm maintains its shape even under high load, enhancing sound fidelity. The additional aluminum dust cap not only protects the internal components but also improves the acoustic performance of the Subwoofer by shortening resonance times. The injection-molded foam surround with VAST™ technology maximizes the diaphragm area for more efficient bass reproduction.

How does the ventilation of the Power T1S2-12 affect performance?

Ventilation is a central element in the design of the Power T1S2-12 Subwoofer. The ventilated pole shoe ensures optimal heat dissipation from the voice coil, preventing overheating and thus maintaining reliability and performance at high levels. This ventilation also reduces the mechanical resistance for the voice coil, minimizing distortion. The die-cast aluminum cooling fins also help keep the operating temperature low, which in turn extends the lifespan of the Subwoofer. Especially with intensive use, the sound quality and bass reproduction remain consistent.

What are the installation requirements for the Power T1S1-12 in a car?

When installing the Power T1S1-12 Subwoofer in a car, certain dimensions must be considered to ensure a proper fit. With a cutout diameter of 285 mm and a mounting depth of 76.5 mm, the Subwoofer is relatively compact and can be installed in most vehicles, as long as the enclosure meets the required specifications. The sealed enclosure should have a volume of at least 31.1 liters, and the bass reflex enclosure should have a volume of 56.6 liters. These dimensions are important to optimally utilize the Subwoofer and ensure that there are no space conflicts with other vehicle components.

How much does the Power T1S2-12 Subwoofer weigh for shipping?

Shipping the Power T1S2-12 Subwoofer from Rockford Fosgate requires a look at the weight to choose the ideal shipping method. The shipping weight of the Subwoofer is 7.3 kilograms. This weight includes not only the Subwoofer itself but also the packaging material needed for safe transport. In comparison, the pure weight of the built-in magnet is 0.41 kg. For shipping, the packaging material used can provide additional protection against potential damage, with the weight of the magnet indicating that the main part of the Subwoofer is structurally solid and robustly built.

Versterker was goed verpakt, En heb dit beest heeft zo veel power!

Versterker was goed verpakt, En heb dit beest gelijk getest op volume en klinkt geweldig op mijn subwoofers, Het geluid vervormd niet zelfs op vol volume klinken de bas tonen zuiver, Ben vooral blij dat ik deze versterker gekocht heb. Ik geniet van elke seconde in mijn auto,Ik kon het merk niet van de versterker [gs-audio] maar het is top merk en het is met de hand gemaakt en komt uit Italy is echt goed gemaakt alleen mijn auto heeft het zwaar te verduren alles beweegt, Dus top aankoop gedaan.
