Near the end of the production run, before the grille cloth
is added, the performance of each speaker is tested both audibly and electronically and compared to standard parameters.
The grille cloth
is sonically invisible so speaker performance isn't compromised.
They cover just the drivers, and since the entire cabinet is finished they reveal as much of the attractive front baffle as if no grille cloth
was used at all.
This indicates that the grille cloth
is acoustically transparent and the felt lining the inside edge of the grille frame is an effective mitigator of diffraction.
Then add frames covered with more black grille cloth
to the front and rear of the speakers, but remember that these frames stick out only about 7" each.
The satellite speakers are housed in real aluminum with wood-finish end caps and light gray grille cloths
, while the subwoofer has a wood finish.
