I did find Colin's reply to me at tad "unfriendly", but no matter.
I await his answer to Greg's question with interest.

It almost doesn't matter what "a while" is. Colin has had examples of failures, so they can fail. Gregs experience shows they don't all fail. The combined effect is we know they can fail. without a statistically viable sample we cant make any estimation about the likelihood of a failure, but no matter how many have had Gregs experience of no failure, just one failure means that the reliability can never be 100%.
Its possible that Colin had a faulty sample, and it never happens normally, or it could be Greg was lucky, knowing the while won't change either of those.

What Nick says is very true,but does not everything we buy have the same likelihood of problems ?

Maybe it's because my crossovers are not being rattled within the speaker cabinet?

No just because we know that a cheap plastic toy from the market and an airbus both have a likelyhood of failure, ie not 100% reliable, that doesnt mean they have the same likelyhood of failure.What Nick says is very true,but does not everything we buy have the same likelihood of problems ?
What would you prefer? Colin didnt tell you about the failure he had? It doesn't make Colins life any better to tell you, it doesnt reduce the chance he will have a repeat problem. But it may help you to not repeat what was his failure.

No, as I said earlier, I really appreciate ANY advice.

Be interesting to hear how it goes anyway Phil
I'll be playing around with a Quasar-style crossover myself this week, to blend the Supravox and FF225WK. Need to drill some new holes in the Perspex though ( unfortunately ) as the FF's have yet another bolt-circle to the FE and the B&C's.

Good luck Mark.
I might just go for two very cheap (and nasty) inductors for test purposes, and if it works out I can save up for the Mundorfs.
Just that with the Alpairs, and the CD transport recently my "hi-fi fund" is depleted.

I'm still gathering information re the crossover inductors, but in the meantime I've ordered two 5mH ferrite cored ones for test purposes.
I need to spend money on non hi-fi items (like a holiday) in the coming months, so at least I will be able to try the parallel crossover, and the ferrite cored item is a step up from the one I currently use in the series crossover.

#41 Re: Alpair 12P
Tomorrow (Wednesday) I'm going to reconfigure the crossover to parallel using the components I have.
Two people (whose opinions I trust) have told me the inductor value is not critical, and the cap is not that far out, so I'll see what happens and report back.
It's only temporary till the "right" bits are delivered.

Crossover mods complete.
Just fired them up, and initial impression is "more vibrant".
I have no padding resistor on the Fane, so bass is more "fullsome" than in the past, but that is a plus !
I'll listen to some favourites and see how the balance is.

2R is more balanced.
The 5mH inductors and 100uf caps have come today, but I can't really do anything till Thursday afternoon now.
