I suspect that speakers with "rolled off highs" may not solve your problem. It's possible that the problem you're having is in the brightness region, which extends roughly from 2K to 5K Hz rather than higher up. I believe "rolled off highs," insofar as that means the region above about 5K Hz, result more in loss of upper-octave "air" rather than a reduction of brightness.
A review of the Vienna Haydn Grand at TechRadar said, "A common thread runs through all the Vienna Acoustics speakers we've tried, and it's a thread that distinguishes them from the overwhelming market majority. It concerns a suck-out in the presence zone. And if this feature seemed somewhat less extreme with the Haydn Grand than some of its larger siblings, it was still obvious enough on our far-field in-room averaged measurement. In this case, this was a lack of energy through most of the treble range. On our measurements, the output level fell something like 5dB between 1.2kHz and 1.7kHz..."
You might best be served by looking for speakers that are a bit recessed between about 2K Hz and 5K Hz. If I'm mistaken about this, someone please correct me.
