Excessive sibilance and edge....treat room?


Hi Everyone,

Before I purchase room treatments...

Will treating room help in reducing excessive sibilance and edge? Besides equipment mismatch etc etc...what causes a room to "sound" that way?

Room size is 10 x 14 x 10. It's a bedroom...concrete walls. Wood laminate floor with throw rug. Drop ceiling.

Thinking of treating 1st reflection points...side walls, front wall and back wall(back wall is actually a floor to ceiling wardrobe).

Should I use absorbers (foam or rockwool) or diffusors to achieve my goals? I was thinking absorbers for side walls and diffusors or absorbers for front wall. What do you guys think? Might skip treating the back wall altogether since it's a wardrobe. If I do treat the backwall...I think it would definitely be foam as it's light and I can use double sided tape.

Thanks for your help.

excessive edge May be the room, but too often its a poor interaction between the components, cable, etc. It is OH SO VERY difficult to fix that kind of thing with room treatments. Usually with excessive treating, you still get the edge, but with a dead sounding rest of the audio spectrum.
Silk dome tweeters are 'slow'. They stretch out the HF resulting in your issue. Soft and sibilant, and therefore with an edge. Aluminum, Beryllium, Titanium, Mylar. For in-between, Phenolic is a good compromise. Soft tweeters suck!

Are you kidding?
I think you misunderstood me there. I gave a list of the opposite of 'soft'. If however you didn't misunderstand, then no, I'm not kidding. I hear the same thing with soft dome tweeters.

I'm pretty sure I didn't understand what you were saying. Is it that you think soft dome tweeters sound harsh and have a lot of sibilance, and that metal tweeters do not?
