Eminence GA-SC64

This speaker is delicious. It may not be my go-to if I needed to use just a 1x12 as it is very much a mid-range diva imho, but, what it is designed for - rich, full, American tones -it does wonderfully.
To accommodate it in my rig I actually forked out on an extension cab just so I can hear its voice keeping everything tight and oh so musical.

Me like much

Look up some YouTube videos of 1965-67 twin reverbs. That glassy, warm, mid heavy sound is perfectly reproduced by the GA-SC64. I put a pair in my 73 blackface conversion and was quite shocked how accurately these speakers reproduce that mid 60's Jensen tone. I will say the doping on these is rather heavy/celestion style, so expect a fairly long break in period before these really give up those jaw dropping 3d sounds. Also be prepared to roll some preamp tubes. Avoid the higher gain ones for sweeter treble.

Made my amps come to life! Especially good in my BF Princetons.
