4 ohm 12" speaker recommendation for BF Fender Bassman amp / combo

I recently restored an old 67 BF Bassman amp and made it into a 1-12 combo amp. Thinking about a WGS 12" 4 ohm speaker to get the proper impedance load, looking for recommendations.

I play in a band that does mostly old school blues, R&B, Stax, Motown, some funk, pop, some rock.

So a great clean tone is important, I generally can't crank the amp enough to use the natural amp distortion, I use pedals, Fulltone OCD , Xotic BB etc...

Thanks!
