Hello gang,
I have been listening to vintage RCA 12s in OB the last few months and am enjoying them immensely.  Always interested in trying new widebanders and the Lii Audio F-12 and F-15 interest me.

Has anyone listened to both the F-12 and F-15? I've never listened to a full-range speaker over 12" and have always tended to lean to smaller speakers but these vintage 12s from consoles have changed that.  I know it's all a matter of taste, but would so appreciate anyone being able to articulate the differences between the 12 and 15 and even better yet if anyone has listened to old RCA 12 from the mid 50's to early '60s.

I know this is very opened ended and responses will vary enormously, but I'm just so interested in what a modern widebander can do compared to vintage drivers.

Many thanks,
Rich  

Thanks for the welcome Steve, its been a pleasure reading across the site and forums; a very energetic community that is especially engaging.

I really appreciate your comments on the F12 vs F15. The 12s very high mechanical Q, lower Fs, and efficiency are a bit of a giveaway thou I am sure they sound nice, but you know what I am listening to and know why I enjoy them so much. The 15s lower mech Q, Mms, and higher fs/efficiency are much closer to the antique speakers of the '50s and assume that these parameters may be responsible for the 15s sounding similar. Under 14g Mms is... arresting... the small 8" Visaton B200 are only 4g less is crazy.  Totally appreciate your "hit" description!  I love that "hit" qualification, spot on.  May I also assume that transparency and detail retrieval (in a natural, relaxed way) are also qualities that the 15 possess?  Gotta say... that is an exciting prospect in a modern driver!  Darn you, Steve!  :-)

Thank you again for your reply... can't tell you how much I appreciate your clear and honest assessment, well done sir!!
