We have been using Siva Cones for the past 25 years and would like to put on record that Cones, Spiders and Dust Caps manufactured and supplied by Siva Electronica have played a key role in maintaining quality of sound reproduced by the loudspeakers designed and fabricated at Bali Acoustic Company.
You have maintained consistent quality and there is no variation in sound produced by the cones from one batch to another batch. The cone/spider quality has helped us in producing loudspeakers that are used where identical sound response is needed, like in home theatres, cinema sound and loudspeaker arrays.
We also find that Siva Cones and spiders stand up good to harsh climatic conditions even in controlled outdoor applications.
