Of course... I should have thought of this really! I'm using a pigment_map
and normal_map to make the texture, but for some reason didn't think of
using a texture_map to include the finish. Doh! Thanks for the pointer...
Here's the code I'm using:

#declare GrillWidth = 0.1;

#declare GrillPt1 = 0.5-GrillWidth*0.8;
#declare GrillPt2 = 0.5-GrillWidth*0.5;
#declare GrillPt3 = 0.5+GrillWidth*0.5;
#declare GrillPt4 = 0.5+GrillWidth*0.8;

#declare SpeakerCoverColMap =
        color_map {
                        [GrillPt1 rgbf 1]
                        [GrillPt2 rgb 0.1]
                        [GrillPt3 rgb 0.1]
                        [GrillPt4 rgbf 1]
        };

#declare SpeakerCoverSlopeMap =
        slope_map {
                [0.00 <0,0>]
                [GrillPt1 <0,1>]
                [GrillPt2 <1,0>]
                [GrillPt3 <1,0>]
                [GrillPt4 <0,-1>]
                [1.00 <0,0>]
        };


#declare SpeakerCoverHPig = pigment {
        gradient x
        color_map {
                SpeakerCoverColMap
        }
};

#declare SpeakerCoverVPig = pigment {
        gradient y
        color_map {
                SpeakerCoverColMap
        }
};

#declare SpeakerCoverHNorm = normal {
        gradient x
        slope_map {
                SpeakerCoverSlopeMap
        }
};

#declare SpeakerCoverVNorm = normal {
        gradient x
        slope_map {
                SpeakerCoverSlopeMap
        }
};

#declare SpeakerCoverTex = texture {
        pigment {
                gradient x
                pigment_map {
                        [GrillPt1 SpeakerCoverVPig]
                        [GrillPt2 SpeakerCoverHPig]
                        [GrillPt3 SpeakerCoverHPig]
                        [GrillPt4 SpeakerCoverVPig]
                }
        }
        normal {
                gradient x
                normal_map {
                        [GrillPt1 SpeakerCoverVNorm]
                        [GrillPt2 SpeakerCoverHNorm]
                        [GrillPt3 SpeakerCoverHNorm]
                        [GrillPt4 SpeakerCoverVNorm]
                }
        }
        finish {
                phong 0.8
                phong_size 40
        }
        scale 0.2
};

#declare SpeakerCover =
        sphere { 0,1
        scale <1,1,0.2>
        texture { SpeakerCoverTex }
};
