currently own a pair of Aerial 10T
Between 7.2 and T-8 - which one is better sound
You know what? The 10T you already have is pretty good as spkrs go.
That is, the other two are nothing to keel over about compared to yours (and they sound reasonably similar, I prefer the Theil -- but not because it's really better IMO).
If you're tired of staring at the same spkr & want to change why not opt for a different design, say an open baffle or dipole, or smthing. Regards
