Kef 104/2 Replacements

Just finished re-doing my 1987 Kef 104.2's. Superb sound is back. I would definitely fix those speakers instead of replacing them. I redid the crossovers, had the woofers refoamed professionally and installed the Peerless 25DX tweeters which were almost a drop in. I remember now why all the hoopla about these fabulous classics. Richly deserved. Total outlay $370. Would need to spend thousands for better sounding speakers.

Javachip, apologies for the late response, just came back here today and saw your post. The tweeters I used are the Vifa (Peerless) DX25TG05's. They will easily fit but are not a drop in. I'll be glad to explain if you want. I only replaced 7 capacitors in each x-over and stayed very close to the original values (same mf, slightly different voltage). The were Bennic brand electrolytics and I put in 2 films where they fit, (the 3.3mf and the 10mf ones)No changes done to the X-overs networks. Pretty easy project. Already sound awesome, still breaking in.

I started with similar vintage KEFs and upgraded to Atc, and the sound is indeed a bit different, but preferable to my ears. I wasn’t unhappy with the KEFs until I heard the new speakers.
 

I replaced a pair of 104/2s with 107/2s, a very major improvement.  If you can find a pair they should be in your price range.  Make sure you get the 107/2 KUBE.  For music, even pedal notes of pipe organs, you will not need a sub.  I replaced my 107/2s with KEF Reference 1s and a pair of Velodyne HGS-15s because the KUBE is not balanced and I was moving to Ayre gear that sounds best balanced with no active device between the preamp and amp.  I used Parasound JC 1 monoblocks with the 107/2.
