RF-C805 - 15" Full Range
You see a very unique driver here - a 15" full range unit. It was under development since the end of 2007. At first it was planed as support for a front loaded horn with an 8" RF-C803. First listening tests revealed its huge potential and I decided to keep working on it hoping to create a full range unit. After trying various kinds of cellulose, I decided to employ a hybrid cone (of my own design). Sleepless nights resulted in total success. Real huge full-range driver was born.
Some applications may still need a tweeter. Sensitivity: about 100 dB. Weight: about 17 kg. 4 kg of copper were used for the field coil, which gives 1.5 times reserve of the magnetic field power. (2.5 kg could already provide 17000 Gauss in the gap).
Cone is of a unique Rullit hybrid design: Special Rullit cellulose in the center, balsa wood around (soaked by Rullit recipe), all on leather surrounds and traditional wooden spider.
Where to listen to it? Demo units are coming soon to: Moscow, Russia and Mishima, Japan.
