These power parameters allow for flexible use in various speaker applications, especially for those seeking high power and efficiency. The CLASS-D technology ensures low distortion and stable performance, which is particularly beneficial during loud playback. The low Total Harmonic Distortion (THD) of under 0.2% further emphasizes the quality of sound reproduction. With an extended frequency range up to 20 kHz, you can experience excellent sound diversity.

What frequencies can the Crystal Series GS-420.2 LED process?

The Crystal Series GS-420.2 LED is capable of processing a frequency range from 20 Hz to 20 kHz. This is supported by the integrated high-pass and low-pass filters (HPF and LPF), which precisely control frequencies from 10 Hz to 2 kHz and 90 Hz to 10 kHz, respectively. This ensures that the amplifier can be optimally tailored to your needs, granting you full control over frequency tuning for a perfect soundscape. Especially when listening to various music styles that cover different frequency ranges, the amplifier offers a customized audio experience.

What are the dimensions of the Crystal Series GS-420.2 LED Amplifier?

The Crystal Series GS-420.2 LED Amplifier has dimensions of 230 x 126 x 57 mm. The compact form factor allows for easy adaptation in various installation scenarios, especially in vehicle environments where space-saving is often crucial.
