Jet City JCA112 Recommendation (used w/ JCA22H head)

Hi,
I'm looking to replace the stock speaker in my Jet City JCA112 cabinet. I'm running a JCA22H head (2 channel, 20 watts) into it. My main complaint is the stock speaker+cab sounds "boxy" and the high end is a little shrill (not sparkly at all). At stage volume, I find myself turning the presence all the way down and cutting the highs to about 3 on the dial to combat the shrillness.

I'd like something warmer sounding that's versatile since the majority of my playing is in a worship band. On the JCA22H, I set the first channel up as clean as possible, keep the overdrive channel on a good solid crunch setting, and use a couple of overdrive pedals when needed for leads/tone coloring.

So I guess, "warm" & "versatile" is what I'm looking for. The two that caught my eye were the Reapher HP and the Veteran 30. Am I looking in the right direction? Any pros for one over the other?

Thanks!
