A.R.C Posted December 18, 2010 Share Posted December 18, 2010 Please, can anyone tell -what to change in the crossovers Forte 1with K-24 woofers? Quote Link to comment Share on other sites More sharing options...
moray james Posted December 18, 2010 Share Posted December 18, 2010 I am not a crossover designer so please this is just a suggestion. I would think that you would need to measure the inductance of both the voice coil in a K23 and a K24 and adjust the inductor value in the bass section of the crossover. That would be a good start as the crossover frequency would be maintained. If there are significant differences in the two drivers response that might have to be taken into account. You can purcharse woofers for your Forte from Bob Crites and not have to play with the crossovers. Regards Moray James. Quote Link to comment Share on other sites More sharing options...
A.R.C Posted December 18, 2010 Author Share Posted December 18, 2010 Thank you. But I thought K-24 and CW1228 similar. Quote Link to comment Share on other sites More sharing options...
moray james Posted December 18, 2010 Share Posted December 18, 2010 You can check to see which speaker uses the K-24 and then check for the crossover to get the right inductor value. Regards Moray James. Quote Link to comment Share on other sites More sharing options...
A.R.C Posted December 19, 2010 Author Share Posted December 19, 2010 K23 has a 4 ohm.K24 and the CW1228 is 8 ohms.What exactly do you want to change the crossover? Quote Link to comment Share on other sites More sharing options...
moray james Posted December 19, 2010 Share Posted December 19, 2010 well we may be going at it here at crossed purposes. I got the impression that you were interested in changing the crossover to accomodate a different woofer. An 8 ohm woofer will have twice the voice coil length as a 4 ohm voice coil will and that means an 8 ohm version will have greater inductance (probably close to double). So my suggestion to adjust the crossover inductor in the bass section of the crossover. If however you are asking for upgrades in general for the crossover then new capacitors of higher quality and also possibly new auto transformers for the mid horn. Non inductive resistors are also sometimes installed in the crossover. Bob Crites sells these and there are also other vendors who sell upgraded parts as well. Sorry if there was a missunderstanding hope this helps. Regards Moray James. Quote Link to comment Share on other sites More sharing options...
A.R.C Posted December 19, 2010 Author Share Posted December 19, 2010 I want to use the K24 or CW1228 with minimal modifications the original crossover Quote Link to comment Share on other sites More sharing options...
moray james Posted December 19, 2010 Share Posted December 19, 2010 Why not check with Bob Crites and ask for his suggestion. I have found data that a K-23 is a 4 ohm driver with inductance of 1 mH and a K-24 is an 8 ohm driver with inductance of 1 mH both have about the same efficiency but Qt values are different for the two drivers. K-23 Qt = 0.226 and K-24 Qt = 0.323. The K-24 will definately work in your Forte but as to the exact difference you will hear I can't say. Regards Moray James.
