Top of the Line Super Tweeter by CDT Audio of Buellton, CA
Why do we call this a super tweeter? Using a special textile fabric ‘transparent silk’, CDT Audio has produced a very special tweeter that plays well beyond the range of most tweeters. Japanese researchers have found a link between high frequency sounds in music, which go beyond the normal range of human hearing, to increased brain activity.
What does that mean? If you’ve been looking for something out of the ordinary for your vehicle’s sound system you have found it. CDT’s ES-1200iS is an audiophile’s super tweeter to enjoy every day and share the experience with pride.
Important Notes About Crossovers:
There are no crossovers included. We are happy to recommend passive crossovers. The Rubyserv official recommended starting point for active crossovers is 3,000 Hz at 12 dB/octave. If you will use more than 50W RMS per tweeter a steeper slope is strongly recommended. Install 63 uF bipolar capacitors in line with the speaker wires for extra protection outside the pass-band.
The product warranty does not cover abuse or equipment failure that causes a full range signal to damage the tweeters.
