SURROUND FACTS Surrounds are a critical element of speaker performance. The surround not only affects the bass parameters of a speaker it also absorbs and reflects various cone vibrations throughout the frequency spectrum. Further, the surround often determines the response of a speaker to peak signals. Serious speaker designers put much effort and science into the specifics of each particular surround. The type of material, treatment, thickness profile, curvature, angle of attachment and the exact method of attachment all come into play. There are as many variations of surrounds as there are speaker brands and generally they are not interchangeable. That's why at Audiodogs you will only get parts that meet the specifications for your speaker and not something that merely fits. 

This sale is for 2 American made foam surrounds for your Sound Dynamics 10s speakers with Angle Attach. These foams are the correct density, weight and profile design so that your 10s speaker will function as the manufacturer intended. Not all speaker foams are equal and getting the size right is only half the battle. 

DIMENTIONS: Outside diameter - 9.875'"- 251mm 

                          Roll Outer Diameter - 9" - 229mm 

                          Roll Inner (cone) Diameter - 7.625" - 194mm 

                          Inside Diameter - 7" - 178mm 

                          Roll - 3/4" - 19mm                        

                         Angle Attach 

NOTE: Sound Dynamics used two different styles of speakers in the 10s models, One style is angle attach and is a match for the red foam surround in this add. The other style is flat attach which is not a match for the foam in this add. If your speaker requires a flat attach foam surround please see the add in my store for Sound Dynamics 10s Flat Attach. 

GLUE: Check my store for the appropriate glue for this type of speaker. "Audiodog's Nitrile Rubber or the Extra Strength Black Butyl Rubber Speaker Repair Adhesives" are recommended and are available in 1/2 & 1 ounce bottles.
