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.

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?
Okay, if anyone has something to learn in this hobby, it's definitely me! I would not consider soft dome tweeters to be harsh. Looks like there's a lack of communication here which could very well be attribute4d to me. Sibilance as I may erroneously understand it is a lack of transient precision or clarity. Hard domes or ribbons/planars are unforgiving toward the signal further up the chain, hence a tendency to slur HF transients resulting in sibilance. Soft domes tend to cover the sins of the aforementioned but incidentally fall by nature to the same/similar fate?
