Do most manu. buy or build their x-overs?


There is quite a bit of discussion concerning speaker driver manufacturers (scanspeak, vifa, morel, etc.) and who uses what. But in general I would say that drivers account for less than half of the overall performance of the speaker. The crossover is a HUGE factor, in many cases perhaps more important than the drivers themselves.
So, generally, do most manufacturers of high end speakers purchase their crossovers in the same manner? Or do they build them to suit the selected drivers?
If they are purchasing them, who are the big names? While I can name off a dozen driver manu. I can't think of one x-over manu., only a few designs named for their inventors (presumably).

Don't see that it would make much of a difference as I assume that most crossovers are spec'd by the designer(s) of the speakers. Who actually makes them (as long as a high level of QC is maintained) would be a mute point.

I have heard of one or two designers who specifially matched the crossover components to each/every individual driver (to compensate for slight variations between like/otherwise matched drivers when they are actually in use), but don't recall names/models.

Does anyone know of them?

The labor cost involved in doing this would seem to be a bit crazy, but if such speakers were used in the near field by someone with good/balanced hearing I suppose that their would be an audible benefit.

My old Rogers Ls3/5a's were said to have the drivers (per pair) matched with extreme accuracy (the crossover parts as well), but this was back in the late 70's when labor costs were considerably more favorable for the manufacturer.

They did perform quite well in the near field (my hearing, ear to ear, was also better matched back then).
