cantrelhm Posted December 3, 2017 Share Posted December 3, 2017 I have a pair of kp250s and they have warm tones for vocals and instruments and I have a pair of kp 250 ii and they are so sharp they cut your ears. Is there anything that can be done to the 250 ii to make them more like the earlier 250s? Thanks Michael C Quote Link to comment Share on other sites More sharing options...
jjptkd Posted December 3, 2017 Share Posted December 3, 2017 Replace the mid drivers with k-55v's, I've done that and they sound great that way. Quote Link to comment Share on other sites More sharing options...
Ljk Posted December 5, 2017 Share Posted December 5, 2017 If I remember right the 250,s have a k76 tweeter, the tweeters on the II,s have a hybrid. I believe II,s have the same magnet as k76 but different horn lens, not sure if the diaphragm is the same. Get a set of Bob's tweeters, a k 76 or a II hybrid tweeter which every you like better. Not sure if the crossovers are different. Quote Link to comment Share on other sites More sharing options...

ELSI Posted December 6, 2017 Share Posted December 6, 2017 heresy 2502 c2's are the newest of this pro design. IMO a talk with crites to calm the stock drivers would be a must. The 2502 C2's will pierce your ears. In a heresy size cab they have the most impressive mid horn and driver by size I have seen. Just lovely. What was built in your kp250's and 250ii's are never to be changed and normally the networks neither but in this case you would be good to try. Also and eq is in every room where sound counts even if its not in use would likely help. Quote Link to comment Share on other sites More sharing options...

True but the 250 has a k76 tweeter and the II has a k 792 tweete different lens. I have of one each as sides right now and could tell the difference when I first got them. The II sounded bright, a light shrill. I bought a k 76 to replace the k 792 so speakers would match but have not gotten around to switching them. Mid could the problem but if you have one k 792 and k 76 tweeter you never get a good tonal match imo. Just read post again was thinking he had one of each instead of a pair of each, I would still look at the tweeters first. Are these going in a HT set up?

ELSI Posted December 7, 2017 Share Posted December 7, 2017 The 792 does have better control to match any mid made give or take. Their slope transition better. the 77's are nice when setup right imo Quote Link to comment Share on other sites More sharing options...

Looks like the 250,s have expotenial horn? Not sure if the woofers and crossovers are the same. You could try hooking one of each speaker hooked in stereo and stuff cotton balls or small hand towel in tweeter and see if that helps. Then do same thing with mid and see if 250 II match, sound better. Might see if someone on board wants to trade 250 II for pair of 250,s. Could be easier in the long run.

Always figured they could be swapped out if they were equal ohms Quote Link to comment Share on other sites More sharing options...
Ljk Posted December 13, 2017 Share Posted December 13, 2017 No not true especially with the different mid and tweeters you are dealing with, crossovers are more then likely different from each other. Crossover points, characterics of individual speakers and horn lens could, are different from each other. I have one 250 and one 250II I need to match. In the next few days I am going take out the 250II xover to see what difference are between the 2 speakers. This may help you, may not. Really looks like these 2 speakers are guide different from each other. The horns lens on both the mids and tweeters are different, got to think the xovers are different. Not sure if the woofers are different or not. Might be easier to just sell the II and buy another pair of 250,s unless you could get parts cheap some where.

True, some times getting the parts and rebuilding is the fun part. However it can be time consuming and sometimes not cost effective, just offering an alternative. Still wondering intended propose for speakers, HT? Quote Link to comment Share on other sites More sharing options...

PS I now have a pair of k128013s if anyone needs them. new diaphragms in both. Do they sound the same as 250,s tone wise? Just to make sure you only changed out mid with no xover change? If that's the case might do that to my 250II. Thanks! Quote Link to comment Share on other sites More sharing options...
cantrelhm Posted December 19, 2017 Author Share Posted December 19, 2017 That's all I did. The 128013 were very sharp for live work. They are not as warm as my 250s but now there clean and clear and balanced enough to perform with. Hope that helps. I think that a crossover change would be the trick to get the 250s sound but there pricey for sure. Quote Link to comment Share on other sites More sharing options...
Ljk Posted December 22, 2017 Share Posted December 22, 2017 Just switching the mid may work since they will only be used as sides and not mains. Have not been able to find a schematic for the 250II, been want to take the II apart and look at the xover just can not seem to find the time. Thanks for the info and glad you got the sound you wanted! Quote Link to comment Share on other sites More sharing options...

Don't know where you found it but it will save from opening up one of my speakers! Quote Link to comment Share on other sites More sharing options...
