Down the repair or replace rabbit hole?

[Moondog55]

Over the years I have accumulated several drivers that I have bought cheap or received free only to find that they do not perform as expected/advertised or that I was given because " I build speakers and maybe could use these" from mates.
Yesterday I bought another driver that seemed OK, not open circuit and good travel but hooking it up all top end/ no bass and woofer tester tells me it has a real problem and Fs is 1100Hz not the 30 or 40Hz it should be.
My question is this; at what point do you just send the drivers to the tip? At what point is it worth having a driver rebuilt ?
I'd personally not bother when a woofer has a small magnet and a pressed steel frame but some of these drivers have cast alloy frames, massive magnets and 4inch voice coils and I have a hankering to build another huge box or two and retail on my last $50- buy is about $350- and more.

Micheal at Lorantz hasn't yet replied to my email but I have asked if they have a rebuild service and if so at what cost.

If I can’t obtain a recone kit (or supplies to make one) at substantially less than “list” it goes in the Bin. That practice started back when Speaker Exchange wanted more for the kit than I could buy brand new from McGee.

Factory rebuild $165-
So I guess I'll fork out for a repair
A shame they don't make subwoofers as this size magnet and VC should work for that function; with better travel than 8mm tho

Fs is 1100Hz

That's a large tweeter.

Buy the soft parts kit and rebuild it yourself. It's a fun task and you'll find plenty of YT videos to walk you through. Cleanliness and attention to detail guarantees a successful job.

I've done a few swaps and a couple of surround replacements but rewinding a 4inch voice coil might be a bit beyond me. Also the factory rebuild is about the same cost [ I think] as the parts. Replacement 4 inch voice coils were about $90- each last time I priced one.
