Here are the finished speakers. New mid and treble drivers were installed and new crossovers built. The original crossovers sent all the music signal to the bass driver with no filtering! The two photos show the finished speakers still wrapped in Cling Film for protection but sounding great after several hours running in. The first photo shows the old crossover that simply filtered the mid and treble drivers but not the bass. For comparison the components for the new crossover are shown alongside.
The tweeters used are Scanspeak R2604s and the mid range units Peerless NE123Ws. Crossovers were built using Jantzen Cross Caps, Jantzen inductors and Mundorf resistors.
