Who makes speakers with relaxed high freq.?

Polk LSi 15, no joke. Save yourself some money and buy music. My recommendation would be the amazing Polk Audio LSi 15 speakers with the incredibly refined Ring Radiator tweeter. Read up on them here and elsewhere. OK so you have to live with a Polk badge, but these are a STEAL for the money, I doubt you would find anything as complete or as better, both in build and sonics, than these slim beauties for anywhere around your budget. And your friend's jaws will drop when they find out how good they sound for so little money. They sound huge and have a wide soudstage. Heck, put 'em in the basement for the kids if you don't like 'em !

If I could make a suggestion; if your room is bright as you suggest due to highly refelctive surfaces, I would suggest looking for a speaker that has less dispersion, therefore avoiding the bounce in the first place. You might look into a ZU Druid, it might have what you are looking for.

Good Luck

Dynaudio Contour S3.4 should fit your bill perfectly. Dynaudio makes arguably the best tweeter in the world.

Yes that would be speakers that use the Seas'.

Spica TC-60s and Martin Logan Aerius i's. I have both. Both have slightly rolled-off, non-fatiguing but nicely detailed treble. The Spicas are a bit more rolled-off than the Aeriuses. Both offer superb imaging. I've added a Behringer DSP8024 digital EQ to the Aeriuses, and it's brightened them up substantially, as well as smoothing out and extending the bass response. I like the EQ effect, but you might prefer the Aeriuses straight up. Got my five-year-old used pair in excellent condition for $1,000. My living room is pretty bright, with sparse furniture, plaster walls, and a rug over a hardwood floor.
