sibilence....any cures out there?


I have recently accuired a pair of Nola Viper 1A speakers, while their performence is outstanding generally, the only problem is highlighted sibilence on vocals which is very annoying!!! Is this down to the speakers? Would a change of interconnects help? Any ideas from you guys would be appreciated greatly...

Swampdog, Try some absorbtion at the first reflection points along the side wall and ceiling, if possable try some on the back wall also. Sibilence can also be caused from the high frequencies bouncing around the room.
You could try a product like Jim Goulding's Diffraction Be Gone: http://www.diffractionbegone.com/

You could even DIY your own to see if it gets rid of the problem. All you need is some self-adhesive felt from your local hardware store and a pair of scissors :)
Agree with the treat the room posts, especially first reflection and bass traps.
