    Default Kelly Transducers KT2 renovation

    I recently bought a World Designs KEL84 off Petrat and very good it is too but it didn't have enough puff to work well with my Neat Motive speakers so I looked around for something more efficient and came across these on Ebay.



    I've owned a pair before so knew I liked the sound although they are pig ugly in their dull oak vinyl wrap and even uglier after a previous owner decided to partially varnish them! Still they were cheap and the drivers were in excellent condition. I've never done any veneering before but decided to have a go using sticky back veneer in maple.





    I also decided to try and improve the crossovers and internal wiring so now some Supra cable goes to the drivers without using those nasty little clips as per original and the crossovers have been moved to external boxes with some new elements. Paul (Reffc) gave me a lot of help with these although he did tell me off for buying the relatively expensive Jantzen caps

    The original crossover sat behind the top mid-bass unit



    and the new one in its box



    They're still running in but sounding good already on the end of the KEL84 so big thanks to Paul for his assistance. (I've posted this build elsewhere but thought AoS members might be interested.)

    Fantastic job. The veneer looks so much better. Crossovers are tidy too. Great work.

    Thank you gents. Wife says they look "professional" which is good enough for me. She also says they look big but then after the Neats they are! The crossover "tidiness" is down to Paul.

    Update.... I just knew there was a great speaker in here somewhere but I wasn't quite getting it. Treble in particular was irritating me - just too much for my taste and shrill with it. So this morning I fitted a couple of resistors to give a 6dB attenuation l-pad. What a difference, treble is controlled but no less airy and bass seems stronger though why I don't know. I keep tweaking the volume up instead of down

    Nice job Ian, enjoy.
    There are times when you canít do the sensible thing, when you canít act like a responsible adult at all; you just have to do whatever insane thing comes into your head. When bad people do it they end up murderers, when good people do it they end up heroes, and when the rest of us do it we end up looking like total idiots. But whenís that ever stopped us?

    I'm sure I just read that somewhere else.

    I've heard these now and extremely good they are.
    Very open and crisp at the top end, I imagine they must have been really piercing before the L pad went in.

    The maple finish looks fantastic
