Opinions on vintage Seas alnico

[zmyrna]

I have been collecting vintage Seas drivers to build a DIY open baffle speaker.

For bass, I have 21TV-EW and 25TV-EW (and their ferrite counterparts).

25TV-EW have smaller magnet and sound slower too.

My choice for main baffle will be 21TV-EW (4 on each side).

I might then build two subwoofers out of the 25s.

For mid and HF I have:

21TV-G

21TV-GW

9TV-G

9TV-LG

5TV-HF

Anyone have experience with these drivers?
