I am partial to Jensen C12R and C12K (I had them in my old Peavey Classic 30 and they were both delicious compared to the original mounted, with a preference for the C12K) but I don't know how they sound compared to the one installed in the Eighty Five, which I suppose it could be an Eminence, rebranded.



Hemp cone speakers tend to be much less bright.

I put in an Eminence hemp into a Frontman amp and it killed the excess treble. Didn't fix the tone stack but it did tame the treble.  For your 12" application, the Cannabis Rex is the hemp option.

I was just talking about this with a co-worker.  I believe combos should be open-back, the way God intended.  Just kidding, though I am an open-back believer.
Yes open back delivers a more spatial sound hence fuller effect especially in small spaces but can present weird sonic issues in larger venues.
You may notice that a lot of big pro gigs tend to use closed back cabinets.

A player friend noticed this weird effect at an old wooden school gig where his open back rig was giving him a crossover of out of phase in the position he was limited to in the building. It can mess with your brain and the sonic result can be off putting.

That does not happen as much with a closed back cabinet.
Although it can still effect a closed back cab it is not as bad.
Venues with big Glass windows can have really bad reflections.

I never really thought about it as I don't typically play out, but just at home.  That makes a lot of sense though.

Closing the back is quite easy, worth a try, although it completely changes the speaker box response, there's an amount of docs about, I'm not even try to simulate it with my speaker design SWs, I don't have the speaker con measures, I'll just try it with cutting a piece of wood ;)
