OK to remove Tweeter Grill??

Blueskiespbd,That can effect the tonal balance.I learned that from the VSA VR-6s.I was told to raise the rear/ambient tweeter until it begabn to effect the stability of the soundstage/ imaging,then reduce slightly.It was a very low level and can be effected by the material/construction of the back-wall.

I have been told and have read that the "tweeter grill" is more for protection of the tweeter, but clearly such a device placed over a dome must have some sonic impacts. This thread has helped me to understand what those impacts are, and why the grill may (or may not depending on the tweeter type and grill type) improve the response

Leave grills on if you like muffed sound on the highs.

You shouldn’t remove a tweeter grille or protection. The sensitivity of a tweeter is with the grille on. X-over is designed according to the tweeter’s sensitivity. The tweeter’s SPL will be higher without the grille. If you don’t have a way to boost the woofer, the speaker will sound brighter.

The tweeter grille is to reduce physical energy of sound which hurt and fatigue your ears. The physical energy is what pushing the sound (sonic energy) away from the speaker. Without the grille you will have more listener fatigue and unbalanced sound between the tweeter and the woofer.
