Low frequency choke

low frequency choke

These chokes are suitable for the highest demands and performances. A very favorable price-performance ratio underlines the technical advantages of these coils even more.

The grain-oriented special alloy of the choke core with additional special pre- and post-treatments ensures a very high efficiency, which is particularly important for the smallest losses in high-quality crossovers.

They are particularly advantageous for 18dB or 24dB crossovers where two reactors are connected in series. The very low internal resistance even at high inductance, therefore, has a negligible influence on the speaker efficiency.

Outstanding is a low total harmonic distortion for small as well as large performances. The distortion factor (K3) is virtually non-existent – it remains well below 0.1% even at high power. Nominal value 0.01% … 0.05% – this corresponds to the harmonic distortion of a high-quality output stage (affects the critical listening range 100Hz to 5kHz).

Due to the high saturation range, an extreme resilience of the coil is possible without distorting the original sound image. Even high inductances have no negative influence on the harmonic distortion of this choke.

Due to their construction and assembly, these chokes have extremely good heat dissipation. Due to the high quality of the material used and the constant production monitoring according to ISO 9001, no failures are recorded even after years of high-performance use of the coils.
