Yamaha NS-690II speakers, Great or just OK?

These look like the Famous Yamaha's with the Beryllium mids and tweeter, I believe the NS-690 does not have those.
Can anyone here tell me if these are great speakers or just OK ones.
Just OK, certainly nothing special...

not in the league of the ns1000. it was a less expensive home variation of the brilliant pro monitor series.
I found a pair in good condition a 4 or 5 months ago, nothing special with tube or ss.
boring sound IMO.....

Well built for sure though.
