    Dear Heykayde, i like to be in touch with other Cizek lovers since many years and actually i can say that the one most expert and specialist in order to rebuild a pair of KA1 giving back to you the original sound is my friend Viljian living in Slovenia. He really know in the deep all details and secrets of Cizek magic circuits and components. Don't sell your KA1 pair cuz can really get back the original sound. I try to involve Mr. Viljian on this post if you agree. Regards Sergio

    Welcome here Heykayde. So nice and interesting your story at Cizek factories. I'm an italian lover of Cizek spekers since 1980 when i bought my pair of Model III at 18yo Actually i have at home one pair of Model I, 2 pairs of Model II, 4 pairs of Model III and one pair of MG27 that need to be restored. I'm looking since few years for the original spec of the MG27 voicecoils and also for the right spiders. You confirmed my feeling concerning the big difference between the original Peerless and the Peerless assembled on Cizek spekers, as a customized traitement done at Cizek factory and i will be happy if you will help me to find more details about that. Thank you in advance if you will provide additional details or pictures about Cizek speakers and Cizek factories here, Kindest Regards Sergio Italy

    Used to Work at Cizek

    Hi guys, I'm an enthusiast Cizek lover from Italy since i was teenager on 1984 with my first pair of Cizek Model III. In the last couple of years i worked to find and to buy others in my opinion significant speakers of the Cizek production but it's quite hard to get the items in good and unaltered situation. I will be really grateful to all the friends here and especially to the workers at the main Cizek factory for any help or suggestion in order to restore the factory's condition of these fabulous speakers. In particular i have a quite urgent matter concerning my couple of MG27 sub mono bought 3 years ago Unfortunately the first owner gave the 4 woofers to a maintenance store and they changed the voice-coils and the spiders of these woofers without a serious reason. At this moment the new spiders are too hard and also i think that the new voice-coils are really different from the original. Even the resonant frequency in free air of each woofer at the moment is 16Hz instead of 12Hz as showed in Mg27's specs. I will be really grateful if someone in touch with who worked at Cizek factory can help me to find the original Mg27's spiders and voice-coils. In alternative i will really appreciate to receive just the full specs of the original voice-coils. Thanks to a long work of investigation i found some pictures of Model's 1 woofer voice-coils and the original advertising of these speakers. With these details i can imagine the following specs For the Model's 1 woofer aluminium voice-coils: Diameter : 38mm Copper wire size : AWG28 Number of Layer : 2 Number of turns per each layer : 61 Rcc : 3,2 Ohm Now, looking at Mg27's circuit,and also at the Mg27's woofer magnet height (almost the double of Model 1's woofer magnet height) and at the declared specs of Mg27 i can just suppose the following specs about Mg27 voice-coil of each Mg27's woofer: Diameter : 38mm Copper wire size : AWG28 Number of Layer : 2 Number of turns per each layer : 122 Rcc : 6,3 Ohm Even with this investigation and even if the calculated parameters are just hypothetical i still without some details concerning Mg27's woofer original voice-coils as the material of the core (aluminium or paper??), the inductance in free air and the total lengths of the core, so i will be really really grateful to who will help me to get the originals voice-coils (and spiders) or in alternative to who will let me know these parameters in order to restore the original situation of these woofers. A secondary matter is the one regarding a special customized improvement done by Cizek factory on the famous Peerless tweeter before to be installed on the speakers. This story still a mistery so i think that just a worker at the factory can help on that. But i can confirm that the customized tweeter by Cizek factory sounds much much better than the original Peerless stock one Finally the last question regarding the not usual profile layout of the 8 inches original foam surround installed by the factory on the Model II and Model III woofers in order to find the right or similar replacement. Thanks to everyone for any help about that. Sergio sergiopxx@hotmail.com Ph. +39 3288373006 ITALY
