Sorry no. The only 8"ers I've had a listen to (in a local store) are the truths. Allow me to ramble about what I have heard, and how I felt about them:
M-Audio DX4 (or it's earlier equivalent, not sure which) -- These where quickly blown out of the running by the rest.
Samson Resolve 50a -- better but quickly moved on (speakers were in bad condition, which probably made them sound bad)
M-Audio SP-5B (This is the model before the BX5) -- Out of what I'd heard, I liked them a lot. Couldn't decide between these and:
Truth B2031A -- Sounded more "fake" to me than the M-Audio's, but were clearly a bigger speaker.
That was all the monitors which were available for me to audition, until the guy checked to see if he had anything more in the back--which was the Wharfedale 8.2s and the Event PS6 (model before TR6). They both blew everything else I'd heard out of the running, but I again couldn't make up my mind from that comparison. The Event's seem to not have enough highs, but they made the 8.2s almost seem like they had too much highs when I switched back to them.
I'd gone into the shop after researching and settling mentally on the KRKs or Wharfedales, and wanting a new, closed box purchase. What I heard that afternoon confirmed the 8.2s as a good contender, so after reading up a little on the Event PS6 (which are discontinued anyway), I ended up ordering the 8.2s and RP6s for a more in-depth comparison
Looking back I find it ironic that at one point a pair of 8.2s sounded like they had almost too much highs, and a different pair in a different place (and A/B'ed against a different make) sound like they don't have quite enough highs. Just goes to show how much various factors can effect the whole decision process--at least the KRKs have the option to turn those highs down.
My current room (not all studio space, mind you) is about 16' by 20' and the 6" sized monitors seem to fit perfectly. I can always upgrade with a sub if I feel the need in the future.
While I don't think it's the right reason to buy a speaker, the yellow cone definitely has tons of appeal, both my wife, and an aunt-in-law (!) have commented on them looking great--and I'll be honest, I think they make the 8.2's look a bit plain (though the blue light is redeeming if not bright).
