Castle Avon and Severn speakers - 1990s

[MisterMoseley]

Evening all
Still have my Castle Severn 2s (although no longer in daily use) and have just acquired a pair of Avons.
The bass/woofer on the Avon is 170mm against the 150mm on the Severn 2. So these are not interchangeable.
However, the tweeters are fabric domed 25mm units and they look the same.
Given that the tweeters on the Severns are in a poorer condition than those on the Avons, but overall, the Severn. cabinets and woofers are immaculate, it’s crossed my mind that it could be sensible to swap them around.
Other than removing both tweeters and checking for any markings on the rear of the units, does anyone know if Castle used the same tweeter in these two speakers?
Although Castle are still in existence, a previous attempt at obtaining information about the Severns failed and I see no prospect of it being any different if I try again.
If the tweeters are indeed the same units, is it also likely that the crossovers are interchageable?
Thanks

The tweeter appears to be exactly the same so you can swap them with no issues.

The crossovers might be identical, hard to say with that.

It's possible the crossovers are the same but unlikely, however if they look the same, have the same layout and if the values are the same then they're the same in which case why do you want to swap them?

@macca

Thanks. I was hoping this would be the case.

I’ve tried the ‘spare’ crossovers in my Severn 2s and am absolutely convinced that I can hear an improvement in SQ compared to the original crossovers. Thought it might be worth a try with the Avons, too.

If both sets of crossovers are of the same type, but one pair seems to sound inferior, that could possibly be due to aged and out of spec capacitors.
