Kef 104/2 Replacements

It is unlikely that any drop in drivers will work for this system. VERY rarely can you find drivers that drop in that were not original manufacturer specs.

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.
