Hmmmnn; note that the 70 80 is rated for 80 watts; a good rule of thumb being that the combined power-handling of the total number of speakers used (in this case, one) should be roughly double or more the nominal power of the amp. So, depending on how hard you tend to push the amp and speaker, you might want to go with a speaker that is at least close to that 80 watt rating. The Celestion "greenback"-styled Eminence Private Jack is only rated for 50 watts; the Celestion Vintage 30-styled Eminence Governor is rated for 75 watts, as is the Celestion G12H 30-styled Eminence Wizard. Of these latter two, the Emi Wizard is more likely to give you the bottom-end boost that you seek in this open-back combo, given its resonance and frequency-range. The Wizard A 12" speaker with enchanting tonal characteristics borrowed from Private Jack and The Governor.
Coloration: Very articulate, but with a hint of grit. Nice sustain and exceptionally good tight bottom.
Cross between Private Jack and The Governor.
Genre: Classic Rock tones of the 60’s and 70’s. Look through the various Eminence speakers listed on these several 'pages starting here, being sure to compare power-ratings, characteristics, and specs via the links for each model listed. Bestaluck, and keep us posted on what speakers you try and how this works out for you!

Cool; I mistakenly thought that your amp had an open-back (I looked it up and Blackstar's 'page didn't mention it, or I overlooked it). In any case, yeah, I think Eminence's The Wizard will work well for you there. It would likely be my pick, or one of a combination of speakers, if I were buying some Eminence speakers for my Marshall "plexi"-flavored Fuchs Lucky 7 head, closed, ported, or open-back. Note that the Emi Wizard is a standard/stock option on many Fuchs amps and cabs.
Again, keep us posted, let me know what you try and how it works out for you!

I take it you like it then; if so, that's great!
How does it do for the low-end you were wanting more of?
How do you like the midrange? Are you finding it a little scooped, and if so, in a good way or a not so good way?
In your amp, is the Emi Wizard treble bright, harsh, warm, smooth, what?

Hmmmnn; note that the 70 80 is rated for 80 watts; a good rule of thumb being that the combined power-handling of the total number of speakers used (in this case, one) should be roughly double or more the nominal power of the amp. Why? As long as the speaker's peak exceeds the amp's peak at least nominally, there wouldn't be an issue.

Why? As long as the speaker's peak exceeds the amp's peak at least nominally, there wouldn't be an issue. 'Cause tube-amps tend to peak a LOT higher than their nominal RMS rating, and many players tend to push them HARD. (Guilty!  ) Better safe than sorry! Better to have and not need, than to need and not have (and have burnt speakers)! For an example, classic 100 watt Marshall stacks of the late '60s and early '70s had two 4x12 cabs, each of which were rated for 100 watts (4x25 watt speakers in each cab); 50 watt "half-stacks" would have one 4x12, again rated for 100 watts. This was a very deliberate arrangement on the part of the people at Marshall and Celestion at the time. Here, Jim Seavall of Scumback Speakers put it very well and raised some good points: AMP Wattage!
Please understand one thing. Most amps are rated for their advertised RMS wattage at clean signals before the edge of breakup. On most amps that's going to be at 3-4 on the volume knob. Your typical old Marshall Plexi circuit 100 watt amp head (1959, Super Lead/Bass amps) puts out 120 watts at 4 on the volume knob. But you like to play it at 7, right? :-) If your amp is healthy, around 7 on the volume knob it puts out 180-190 watts (or more). The guys at Marshall knew what they were doing when they put the "100" logo in the corner of the cabs, but that still meant that you needed two of them to handle a 100 watt amp that put out 180 watts at the levels you set the amp! Please get your amp tested for it's real output wattage, because no one likes the smell of a melted speaker, OK? Always figure you need twice your amp's rated RMS wattage in speaker power handling to safely run your amp on 10.
If you get two 30 watt speakers to run with your 50 watt amp, and dime it, they'll be good to go for awhile. I don't know what timeframe "awhile" is. I've safely done it for 2 hours straight, without issues. I have not done that for extended periods, so you want to take that into consideration with all the OD pedals, clean boosts, and so forth that push speakers to raise your level for solos. Use your good old common sense here. Sure, your old small block Chevy/Ford sounded great and was running awesome at 8000 rpm for "awhile", then the crank, piston, or connecting rod broke through the block, and you weren't mobile anymore. Use the same common sense judgment with choosing your speaker wattage.

Okay, that makes sense. I've always thought in terms of solid-state and the tendency of amp manufacturers to overstate their amps' output, so this is a bit of a new paradigm for me.

How does it do for the low-end you were wanting more of?
How do you like the midrange? Are you finding it a little scooped, and if so, in a good way or a not so good way?
In your amp, is the Emi Wizard treble bright, harsh, warm, smooth, what? First of all, I'm an old school guy so I had to look up "Scooped"  and no it doesn't sound like the mids are gone. In fact it sounded more "Scooped" with the 70/80. It has more bottom and it seems to be a little warmer on the clean channel. This is with a Les Paul. It's hard for me to describe, but I know it when I hear it. I can get a cross between old school crunch and a little harder rock sound. I'll have to play some more a performance volume. I want to play around with the pre amp tubes a little too.
