Patented VAST technology for larger membrane area

Rockford Fosgate's VAST (Vertical Attach Surround Technique) technology increases the effective cone area by up to 25%. This increase results in better bass response without changing the overall dimensions of the subwoofer. What does this mean in concrete terms? A larger cone area means more air displacement, resulting in more powerful and deeper bass. Compared to other subwoofers of the same size, the T1D415 / T1D215 offers superior bass reproduction and density. A smaller cone area would significantly impair bass performance and result in a flatter soundstage.

Flexible and robust die-cast aluminum basket for extreme installations

The Rockford Fosgate subwoofer features a FlexFit die-cast aluminum basket, which ensures maximum stability and flexibility. This basket supports extreme installation positions in the vehicle without compromising its structural integrity. Thanks to the robust material selection, the basket ensures a stable playing position even under intense vibrations, ultimately guaranteeing clean and precise bass. Comparable products often use inferior materials that yield more quickly under pressure or introduce additional resonances into the sound.

High-temperature resistant 3 voice coils with Nomex reinforcement

With its high-temperature-resistant 3 voice coils, the Rockford Fosgate subwoofer is designed for extreme power ranges. Nomex reinforcement improves thermal resilience, resulting in consistent power output even during long periods of high volume play. This prevents premature overheating and protects the voice coils from damage. Other subwoofers not reinforced with Nomex may fail more quickly or experience performance degradation under the same conditions.

Dual 2 Ohm and Dual 4 Ohm impedance for flexible connection options

The Rockford Fosgate subwoofer is available in both dual 2-ohm and dual 4-ohm configurations, giving you flexible connection options. This versatility is especially useful if you want to connect multiple subwoofers in parallel to get the best sound from your system. A lower impedance, for example, supports more power, but may place a greater strain on amplifiers. Rockford Fosgate's flexible approach optimally adapts to different setups and performance requirements.

High power handling with a maximum of 2000 watts and RMS of 1000 watts

With an RMS power output of 1000 watts and a maximum power handling of 2000 watts, the T1D415 / T1D215 delivers breathtaking SPL levels. This performance ensures that the subwoofer delivers a clear and low-distortion sound even at intense volumes. Comparable models in the car hi-fi scene often don't reach these levels and are more prone to distortion under load. This makes the Rockford Fosgate subwoofer ideal for setups that demand rich, heavy bass lines.

Adjusted Thiele-Small parameters for precise sound

The Thiele Small parameters, including Vas (102 liters), Fs (26.3 Hz for D2 and 27 Hz for D4), and Xmax (16.4 mm), are precisely tuned to deliver outstanding performance in sealed and bass-reflex enclosures. These parameters specifically determine the subwoofer's characteristics in sealed and bass-reflex applications. A Vas value close to 102 liters indicates efficient subwoofer performance, which is perfectly suited to larger enclosures. A lower Vas value would offer less bass precision and depth.

Durable poly-cotton spiders and fatigue-resistant slats

The use of durable polycotton spiders combined with fatigue-resistant fin wires ensures outstanding stability of the cone movement. This design decision minimizes mechanical losses, thus achieving improved low-frequency sustainability. This is particularly useful in continuous high-power operation, where other components might lose resonance stability due to mechanical degradation.

Optimized pole core and spider ventilation for better cooling

The ventilation of the pole pieces and spiders is key to effective heat dissipation in the Rockford Fosgate subwoofer. This ventilation system prevents heat from building up in the voice coil, which would drastically increase its performance and durability. Such a ventilation system can lead to overheating and permanent damage in other subwoofers. Rockford Fosgate's design thus ensures consistent acoustic performance with consistently efficient cooling.

Kevlar fiber-reinforced paper cone for durable sound structure

The paper cone reinforced with Kevlar fibers offers an optimal compromise between stiffness and weight, resulting in improved bass precision. This cone offers unprecedented rigidity and prevents unwanted resonances from compromising sound quality. On average, Kevlar-reinforced cones are more durable and offer better frequency response at more aggressive bass frequencies than conventional materials.

Bass reflex and closed cabinet volume adjustment

The Rockford Fosgate T1D415 / T1D215 subwoofer is optimized for 63.7-liter sealed enclosures and 75.3-liter bass-reflex enclosures. These configurations are ideal for users who want to choose between the directness of a sealed enclosure and the more expansive, resonant sound of a bass-reflex configuration. A smaller enclosure volume would not realize the subwoofer's full acoustic potential, while a larger volume might produce a more dominant but less precise bass.
