Serblin's newest speaker is a four-way five-drivers design with two 230mm modified Scan-Speak woofers. These hidden drivers fire against the rigid rear baffle and deflect their emissions through vertical slots. The cabinet otherwise is sealed and not ported. There are similar breathing slots close to the sides of the two 100mm coated paper mid/woofers with metal phase plugs which release the internal air pressure. These paralleled mids loaded into a separate chamber are equipped with rigid moulded baskets and large motors. The tweeter is a coated Scan-Speak D2905 silk dome which Serblin views as the best transducer Ragnar Lian has designed who counts as one of the most famous driver designers alive. This tweeter is equipped with a non-resonant rear chamber.
Ktema uses same tweeter as the Armati Futuro and SF GUARNERI EVOLUTION
