Frequently Asked Questions about PRW 50

What technical features does the Eton PRW 50 Midrange speakers offer?

The Eton PRW 50 is a 2-inch Midrange speakers designed for a wide range of vehicle models. Its core features a 50 mm paper diaphragm along with a 19 mm voice coil, enabling efficient sound transmission. It has an impedance of 4Ω and a rated power of 15W RMS, ensuring high reliability in use. The speaker is housed in a fiberglass-reinforced polyamide basket, which comes with powder-coated metal brackets. Additionally, it features a neodymium magnet, making it not only powerful but also compact and versatile.

What frequencies does the Eton PRW 50 cover?

The Eton PRW 50 covers a wide frequency spectrum that ensures an optimal sound experience in your vehicle. The frequency response diagram shows that the speaker operates at frequencies between 20 Hz and 20 kHz and can provide a volume between 70 and 100 dB. These characteristics make it ideal for effectively reproducing both low and high tones. Particularly relevant is the clear reproduction in the mid-frequency range, which ensures the intelligibility of voices and instruments. The resonance frequency TSP of the unit is 202 Hz, while the magnetic force factor is 3.1 Tm.

What are the installation dimensions of the Eton PRW 50?

The Eton PRW 50 is ideally suited for universal use in vehicles due to its compact dimensions. It has an overall diameter of 58 mm and a mounting depth of 23.1 mm, allowing for easy installation even in tight spaces. The mounting diameter is 55 mm, while the thickness of the basket rim is 3.5 mm. Screw holes with a diameter of 4 x 2.7 mm are provided on the brackets to ensure a firm and secure attachment in the vehicle. Thanks to these dimensions, it fits into numerous vehicle models.

Which cars are compatible with the Eton PRW 50?

The Eton PRW 50 was specifically designed for compatibility with a variety of vehicle models, especially those from Mercedes-Benz, Toyota, and General Motors. Thanks to the standardized dimensions and the included powder-coated metal brackets, the speaker is ideally suited for a plug & play installation. The speaker can also be easily installed in vehicles with a 4-point mounting system, as the mounting ears can be adjusted to different brackets. Whether it is a German, Asian, or American vehicle – the PRW 50 is versatile.

What type of magnet material is used in the Eton PRW 50?

The Eton PRW 50 is equipped with a powerful neodymium magnet. This magnet material is known for its high energy density and allows for a compact design of the speaker while providing high magnetic force. This results in a powerful and dynamic sound with a small installation size. Neodymium is lighter than other conventional magnet materials and still offers enormous performance capabilities. Especially in applications that need to combine compact size with high power, neodymium offers unbeatable advantages, which are consistently implemented in the PRW 50.

How is the Eton PRW 50 installed in the vehicle interior?

The Eton PRW 50 is designed for easy installation, which is structured as a plug & play solution.
