I suggest you get these kits instead.

Aftermarket, like the Japanese ones, seem to use the same parts, but these are complete, including the aluminum dome, which is an IMPORTANT part of the sound.
Keep the Japanese page as reference, it is very detailed.
Only problem withthye Americankit is they include white carpenter´s glue to bond cone - voice coil - dome - spider which is ludicrous.
Way too soft and gummy, will kill rreble.
Proper is a speaker specific adhesive, such s light Epoxy or even better some Hernon speaker specific one such as:
Loud speaker adhesives - CTA Ltd
get a supplier more practical/closer to you.
They suggest many specialized adhesives, for the non critical joints you can use the rubber cement type supplied with the kit but fo the very stong and light voice coil to cone and metal dome you need this one or some equivalent:
As of:
in the 30s 40s 50s maybe even early 60s it was easy to answer: either of them, plus maybe the rare Western Electric, Westrex or Vitavox, but later many excellent competitors appeared.
In that era, THE main PRO Audio market was Cinema, it´s hard to evenly fill a 1500 to 2500 people (sometimes more) huge boomy rectangular room where everybody who paid a ticket had to listen clearly so they invested whatever was necessary, cost no object.
That said, JBL is still a powerhouse and the others more or less clone their designs, so .... 🙂

Someone said recording studio speakers have to be changed every 3 to 4 years, they lose fidelity by a minor but noticeable amount...
True or false?

i have seen studios that still uses ns10s. familiarity and knowing how it would sound like after mixing is probably more important. and i dont quite see the rationale why they would degrade for such a short period of time? but im not a pro so take it with a large grain of salt.
its a patch up job. the guy i brought them too have a large inventory of cones from jbl, altec, ev and almost every brand imaginable. luckily he found a some torn cones from some jbl le8ts that he reconed from before he used those to patch what is missing . the surrounds arent original but the guy has a diy rig to cut the edge to the right sie. now they sing wonderfully in temporary 3 cubit feet cabs with 4*2'' vent.
