You heard the vocals added sibilance & slight rough-edges because you DIY diffuser only work at mid range....

Within its working range it able to reduce the reflection and spread the sound 180 degree in horizon back into the room, but above 2.9Khz it act like a bare reflective surface, it reflect the sound directionally to you....worse part is those curtain around the diffuser make the reflective high frequency even more obvious...you open out all curtain the sibilance will reduced, but the best solution is to make sound diffuser that able to diffuser at least to 12Khz....

In my personal experience, High Frequency diffusion is much more important then mid and low frequency.The reason is because for 99.999.....% of loudspeaker, the higher the frequency the more directional it is , with High frequency diffuser at five surface (2 side wall,front and back wall, ceiling), we able to create a illusion of diffused sound field like in live musical event....Say given a choice between 2 diffuser, one working range is 250Hz to 3.4Khz and the other one of 1Kz to 16Khz, I would choose the latter any time in any room.
