Review by Archimago.

My recommendation: Sound Power and Early Reflections seem to follow the On-axis, so it should be fixable with equalization. Maybe.
You can extrapolate performance from these 2 Edifiers for the Edifier A80 that you're looking at.
Wharfdale - EVO 4.2 BS speakers - $650:

-3dB (resp. -6db) point v.s. reference is at 113.0Hz (resp. 82.0Hz).
Preference Score is 3.7 and would be 6.9 with a perfect subwoofer.
Amir's review? HIGHLY Recommended.

Although...keep it mind, it's bass shy.

Really?
No Bose please!

My thoughts: Looks okay. Small issues fixable with Equalization.
PSB - Imagine XB BS Speakers - $400:
No full spinorama is available.
I have these, and I like them, but I'm biased...so...
ELAC Debut - 2.0 B6.2 BS speakers - $400:
View attachment 131478
-3dB (resp. -6db) point v.s. reference is at 60.0Hz (resp. 47.0Hz).

Monitor Audio bronze BS speakers - $350:
No spinorama available.
Wharfedale Diamond - 11.1 BS Speakers - $325:
See previous Wharfedale spinorama I showed.
Behringer Eurolive B210 Speaker - $250:
That's a PA speaker, and they'll have their own issues. They usually sacrifice on-axis performance for loudness. We haven't seen any PA speakers tested yet, so it's hard to say. But I would avoid PA speakers until we test some.
Kevler 15" passive speaker EON-15 $200:
See my notes on the Behringer.
Tannoy - Revolution DC4 4" Dual Concentric HIFI BS speakers - $200:
No spinorama available.
That took a bit to gather...
