How do I Address the Sssssss’s?

[Dan Twomey]

On certain songs there’s that sharp Ssss depending on the word the singer is pronouncing. Suggestions for correction?

Sibilance, as it is called, could be in the recording, room, or speakers... For Human Voices the sibilance zone is approximately 5kHz to 8kHz or so... You could try an EQ cut in that area or try broader Q curves in that region to deal with the brightness... If you don't have any room treatment you could try some broad band absorbers with attention to that frequency zone...

If you have a flat screen tv in between your speakers, like I do, you might try a wide band absorber over/in-front-of the tv when listening to music...

What is all of your equipment and speakers Dan... and do you have a dedicated room?

 

[Dan Twomey]

I'll keep my answer very general for now. I've been using REW and a UMIK-1 to implement a house curve with the MiniDSP 2x4HD.
So far I've had great initial success and my question about the Ssss would fall under the category of fine tuning. Which filters and or frequency range might
I look at for an answer?

Here's a pic of my equipment in my dedicated listening room.

Hmmm... wonder if it is something going on with the ribbons.

I don't know that you can filter it, but you could try. I'd go back to what ddude003 is suggesting.

What does the REW sweep look like up top?

5kHz to 8kHz or so.. I already saw your kit in another thread... Your line array speakers are too close to the front wall and have a very reflective flat panel tv in-between... It also appears that there are no room acoustic treatments... My above suggestions stand...

Here are a few crazy suggestions... Tilt your speakers back a few degrees... Disconnect a few (2-4) of the bottom ribbon drivers... If you own a few cats, velcro them to the walls... Or, you could suggest the vocalist get their face a little farther away from the microphone...

Well, this had zero effect and you probably don't have a clean "speaker" measurement with that line, but..
...try a -4db centered at 8kHz, Q 8.0

Yikes. How did you measure with the original crossover filter design? What are the XO frequencies?

 

[Dan Twomey]

Two fourth order LR's crossing at 2.5Khz. One potential problem is that they're wired in the opposite polarity. I've read two fourth order LR's should be the same polarity.

On a positive note. I'm slowly gathering the required gear to go active.

Ok, so I understand you, there is a passive filter, LP and HP legs both 4th order electrical, or electro-acoustic (the actual measured response combination of the filter and the drivers/baffle)? And one is inverted?

 

[ddude003]

Nailed it... 7.25kHz... Why not post a .mdat file so we could really see what is going on? Your going to need moar cats and velcro...
