Hi All

Thought I'd run this through this forum section for any advice.

Help with L15 Refurbish

1) Cabinets, dampening, leave it, add to it, remove/replace it ????
2) 034 Tweeter has lost it's silver paint/aluminum? covering, works, replace, repaint ??
3) Crossover, Cap replacement suggestions
Change inductors to air ?
Change resistors ?
Build external "charged xover" ?
Change xover frequency to 3K(read somewhere?)
4) Change connectors
And anything that will help with project.
Not worried about keeping original.
Just having FUN.
Pair of 4406's after these.

Thanks

Quite a range of options, but personally, I'd focus on the cosmetics (perhaps a light spray of aluminum-looking paint on the tweeter dome). How's the grille and cabinet?
Changing out crossover parts is not always an improvement, and without a way (beyond your ears) to baseline/change/improve, it's easy to talk yourself into almost anything sounding 'better'.
Not one to discourage experimentation though... I'd just do it on a different crossover board and keep the stock one around.
Fun project :)

It looks like you already have air core inductors.
