CSS Audio LD22
CSS Audio LD22
The CSS LD22 high-performance tweeter uniquely fits between the usual standard tweeters with
19mm (3/4 ") and 25 mm (1") voice coils. A 22mm aluminum voice coil with copper cladding and
a wide suspension ensures a low Fs and thus supports a deep coupling to the
Crossover. A rear chamber and an external neodymium ring magnet ensure very low
Compression distortions than would be possible with conventional designs. Carefully selected
Materials and the coated fabric dome enable reproduction up to 40 kHz.
Test Conclusion Hobby HiFi 1/2020;
CSS provides with the LD22 an excellent dome tweeter, usable from 2000 Hertz and thanks to
Neodymium drive pleasantly compactly built.
