Well I have put this off as long as I could but today I have started on my project to convert 4 x KEF 103 speakers in to two stacked units . Please note that only one Tweeter each side will be connected so there will not be issues of treble coming from two different points and mashing up the stereo effect. The bottom speakers will have the bass unit only connected in parallel with the upper units and so hopefully give me some additional boost to to this part of the sound spectrum . Using Dirac Live 2.0 should smooth any transistions and keep things balanced.
Today I have removed the drive units from the cabinet and removed the passive crossovers (strange this pair had Elcap Capacitors in the crossover rather than the electrlytics in my origianl pair ) .
I have drilled four holes for the additional binding posts for the bass units at the back of the speakers mounted the posts and soldered the wire connection . I have also started to paint the cabinets black to match my original pair while the drivers are out . I have also put new gasket material around the edges tio ensure a good air tight seal . These are very good silicon tape and make a very positive seal but are also not prone to decay and drying like the originals . Makes things easier if I have to do any additional work that this gasket can be resealed a number of times without problem .
Not much done but at least it is a start . Will try and finish the painting tomorrow and then wax the cabinets . Then just a matter of putting the drivers back soldering the connections and building the planned plinth for them to sit on . Once that is completed I will then have to get in the dangerous mode of creating the Active Crossover and running a full Dirac treatment . Hopefully at the end I will have something that is not only working but usable .
