Thanks a lot Earl K for taking the time to calculate with WinISD pro.

I have learned a lot reading your posts on LH and still learn here on this Altec User's board !!!

It is a coincidence but i have a 2 way DIY project with a pair of JBL 2234H. If the 927-8A can be used in the same enclosure i will be able to compare them.
You're welcome .

If you buy them I hope you will take some more pictures ( as well as take some physical measurements of these rare speakers ) so as to add to the overall knowledge base of old Altec products ( since this model is so rare ) .

I'd like to know ( for instance ) just how high ( deep/thick ) that top plate is .
( ie, I'm trying to figure out if this woofer has an underhung or overhung voice-coil topology ) . ( FYI, that official Xmax stat. seems somewhat optimistic , unless it's for an overhung voice-coil or perhaps the stat is really an X-mechanical before damage statistic ) .

If you end up using these in the same boxes as your JBL 2234(s), I'd love to hear your sonic impressions / after an A/B comparison ( keep in mind the 927-8A appears to be a 10 ohm woofer , which will somewhat skew the ability to make an easy comparison ) .
