Inherited these from my dad a few years ago and spent some time replacing the drivers and tweeters as they were knackered. (was told the drivers that were fitted at the time were Elac 8", but there were no markings and they weren't a matched pair anyway) The original tweeters were goodmans DT4 silk domes. I replaced the main drivers with a matched pair of KEF B200 SP1063A and the tweeters with a pair of Seas prestige H1280-06 22TFF tweeters. I reused the original crossovers that were there. The cabinets are 24L or 0.85cu.ft and ported with a 52x155mm port. Having read the specs on the kef drivers I've listened to them with the ports plugged. I have also tried unplugged too and found little difference. (although I've left them unplugged) Overall I find them quite pleasing to listen to, however I don't know if there are any improvements that I could make to them.

This is how they look now.


The crossover AFAIK is 1st order for the LF/midrange and 2nd order for the HF. The capacitor is 4.7uF 63V. I don't yet know the value of any of the other components. (I'd rather not have to dismantle them to find out)



I'm guessing a custom crossover for them might be better suited. If anyone can rough guess (or knows) the crossover component values can plot the response for me, that would be a great bonus.
