Amazing resource, thank you Wieslaw!

Dave only seems to be considering the SP1014 which has a Qts of 0.51 so is suitable for a sealed enclosure.

 

[Budatone]

Another slight change of subject - is there a general consensus on T27 vs 4001G for the +13 KHz range?

Note that an 8 ohm version of the Coles super tweeter, the 4001K, is available here: https://www.falconacoustics.co.uk/coles-4001k-8-ohm-super-tweeter.html

A 4001 was often added to help the top end of the T27. They are for quite different purposes.

As in the Cambridge Audio R50 speakers:

The Cambridge and the Falcon (not the current Falcon) diy design it is essentially a clone of. You can see enclosure and XO details in the HiFi Answrs article.

There was also a simplier second iteration. http://p10hifi.net/planet10/TLS/downloads/Pro9TL-Mk2.pdf

That’s really interesting, thank you. So my purpose will be to add top end to a Celestion HF1300 which I think falls off pretty quickly after 13 KHz

Bumping up an old thread. Found a pair of KEF C40s. The B200 in the 2.5way is a SP1205. Apparently another B200 small magnet variant? Thank you.

B200 SP1014 were used in a pair of Celef Monitors I owned, which we’re reflex loaded.
With drinking straws.
My Tangent TM1s use that particular driver with an open cabinet vent.
Square in Tangent’s case.
