Thanks to Andreas Plodek for these pictures and details about his REALHORNS system.
REALHORNS 18Kw bass horn carbon series driver update 6 x JBL 2267 double 100mm voice coil, double magnet, 3 air gabs Liquid cooled with custom made carbon diaphragms. Optical diaphragm displacement sensor.
Water tubes, 3 x 50mm2 cables to 3 x CROWN I-Tech 6000 Diaphragm displacement measure
15” JBL 2267 modified with carbon diaphragms (made by Miller Instruments) optical diaphragm displace measurement. And of course the sound of the carbon is different the paper diaphragms.
They have more attack, you are more touched and you hear them better.
Carbon is much stiffer than paper, so the peaks of every single wave of a bass frequency is better felt and heard.
Diameter 100mm, 36mm high each coil. Different magnetic system compared to all other speaker companies. Dual gap dual magnets with are located inside the coil.
During the sound check a glass front was dematerialized to light. Now the insurance did not want to pay. They say dematerializing is not insured. I do not think so.
6 speakers with 12 voice coils with 100mm diameter and 36mm high each. At the moment we drive each coil with 0,375Kw RMS means 4,5 Kw RMS and 18Kw peak by a Crest of 6db all together. But the size of each coils is this big, they should be able to work with 750W RMS, that means 36Kw peak for the system. But at the moment the maximum peak power in is 18Kw.
The welding connectors guarantees lowest resistance and because of this best possible damping factor, together with the 50mm2 welding cables. Two speakers are connected in parallel. So there are 3 inputs of the cabinet.
The cover plates of the 6 speakers are cupped so the airflow of the voice coil cooling could work properly.
The size of the front opening is the same as the 6 unit’s 15” carbon diaphragms. They are driven by 12 x 100mm coils. Together this 12 coils could be seen as one coil with 1200mm diameter !!!!!!!!!!!!!!!! This is about the double of the front openings diameter. Just count this together and be impressed.
Building up the horn with an electric hoist and the help of Alex. There are 15 connectors each side of the horn elements to fix them together properly.
