What is the issue with raising the mids via mixing console or daw while using the beta 52?
The general preference is to use as little EQ as possible. EQ is assumed to degrade the signal in various ways. It adds noise and also phase distortion.
Ideally you choose a mic and mic technique that gives the desired sound without needing corrective EQ. In some instances, you want a mic that faithfully reproduces the sound source. In other instances, you select a mic that intentionally colors the sound.

I would expect overly scooped mids with a lot of gank produced by the spike at 4khz (IMHO

). Course if that is the sound you want,

Beyerdynamic M88TG frequency response, showing proximity effect at different distances.
This is reportedly a fairly bright mic on a bass cab, but I would expect it to sound way more natural than a Beta 52A. No doubt some EQ would probably be required.
EV RE20 frequency response, showing effect of low cut filter.
This mic uses a technology called variable D, so there is little to no proximity effect. Should give a pretty accurate representation of the sound source.
I would not hesitate to use an M88 or RE20 to mic a bass cab. B52A sounds pretty decent on bass drum, so it's not like I hate the mic. But it would probably not be my top choice to mic a bass cab.
