Guest Chet6119 Posted October 9, 2008 Report Share Posted October 9, 2008 Thank all of you for what I have already learned here.I have owned a pair of 20s for most of my life. I have had them connected to my recently overhauled Dynakit that my dad built in '62. I went with a friend of mine to look at some 17s I found on creigslist for him, because he loved my 20s so much. Well, the guy had a pair of 23s also and they were in perfect cosmetic shape (unlike my 20s) and sounded good so they came home with me.They had replacement tweets so I did a search and ended up here.I am about to replace the caps and put the tweets from my 20s in the 23s. I found a post here about 23s that said:"Why is there simply a 4 mfd. cap and 3 resistors on a rotary switch for decrease-normal-increase ? I find it hard to believe the woofer is operating way up in the midrange to 3000-4000cps. The KLH 6 crosses over @ 1500 cps using an 8 mfd. cap and 2-2 mfd. caps and the 3 resistors too. At first I thought someone had played with the crossovers , but a second pair of 23's are identical . I'm puzzled because they shouldn't sound that good ! Dave"Mine have the 4 mfd. cap and the 3 resistors but there is also a "new" 2.2 mfd cap between the switch and the tweet. Before I go ordering caps is this correct? To my ear and the use of a parametric eq, I find that they are about 4db low in about an octave range center on the crossover point which I fount to be at about 1.7 khz. (I used pink noise and swept the frequency on the eq to find the crossover point and did an A B test with my 20s which showed the octave deficit.)Would someone let me know if the 2.2 mfd cap is correct.

Guest MarkAnderson Posted November 7, 2008 Report Share Posted November 7, 2008 As far as I know, the Model 23 just used a single 4uf cap. Sounds like your's have been tinkered with to me. Link to comment Share on other sites More sharing options...
Guest Chet6119 Posted November 7, 2008 Report Share Posted November 7, 2008 Mark,Thank you. I just received my order of new Capacitors end of last week and I am going to work on the 23s this weekend. I'll won't replace the 2.2 caps. When I am done with the restoration I will post my results.Chet Link to comment Share on other sites More sharing options...
Andy Posted November 8, 2008 Report Share Posted November 8, 2008 You should like the 23's a very robust speaker with the same woofer and cabinet volume as the model five (5 lb. magnet !). Very solid bass response. KLH's best two-way speaker in 1968-72 at $160. each.The 23's are a bit of a sleeper in the market place, often selling for much less then the models 17,20,24 which are much less of a speaker.I found a set of four put out for trash, in great condition ! Love em ! Link to comment Share on other sites More sharing options...
