Speaker grills?

I listen with the grills on because the designer of the speaker, Richard Vandersteen, told me not to take them off. You should ask the manufacturer which way is preferred in your particular case.

Many dealers like to take the grills off mainly because speakers tend to sound a little more lively without grills which might give a better first impression to potential customers and help make the sale.

Thanks all! BTW they are JM Labs 926 Electra's.

I have not heard any of the Electra series speakers, but have always preferred the Chorus speakers with the grill covers installed. I have heard several of the Utopia series speakers and I think the drivers have always been exposed. I don't even know of the Utopia speakers have grills.
