Product Review

This is genuine "filleted" foam with a direct-attach inner lip, not the generic knock-off that others may sell. Some of the models that use this foam include: Boston Acoustics A-60, A60, A-60-II, A-70, A70, A-80, A80, 380, 780LF, A-400, A400, CR8, HD8 (10-278-1), HD9, T-100, T100, T-1000, T1000, T-1030, T1030, T-70, T70, T-820, T820, T-830, T830, VR-960, VR960, and others that match the measurements below. Due to occasional variances in Boston Acoustics frames, a few of these models may require you to trim approximately 1/16" off of the outer perimeter.
