Powered Kemper with 1 x 12 Greenback - Lacking high end

Good day everyone

So a couple of weeks ago I got a powered head and am extremely happy with it.

However, last week I got a closed back (relatively big) 1 x 12 with a 2001 English made greenback, and when I use it with the Kemper it just seems muddy and lacking high end (even when using the Texas special in the bridge of my strat.)

This problem is worse for high gain profiles.

The cab section is off, I have double-checked, and I have used both merged and normal profiles from a variety of people.

I moved cities recently and the only other amp/cab I have here is a princeton reverb. When I use the Kemper with the stock 10 inch Jensen in the princeton it sounds great, but not with the greenback. Any suggestions?

Thanks!

Already planning to do that next week.

However, I had one of those Vox AC15 reissues with the Chinese greenback and it sounded a lot brighter than this.

I took the back off the cab and compared. It made it a bit more open sounding, but didn't really relieve any of the muddiness caused by a lack of high end.

Yes!And this is exacty what it has been made for.

I turned the presence up to just below max on the output section and it sounds normal now. I suspect there may be an issue with the speaker but its usable. Thank you very much.
