AIWA CS-880, CS-J88 Speaker Surround Foams

The most common problem with speakers are rotted, torn or damaged surrounds. The surround is the outer suspension part of the cone. Constant vibration, time and the environment cause foam and rubber surrounds to degrade. Cloth and paper surrounds can become brittle. This causes distortion and poor performance.

Luckily, our easy to install repair kits will make your old speakers sound just like new!

A	Whole edge Diameter of	Ideally, in order to adjust the mounting position, there should be a gap of at least 2 mm in diameter relative to the groove in the frame. It doesn’t have to span the entire frame.
B	Outer diameter of roll	It is basically the same diameter as the inner diameter of the frame. Normally, there is no problem even if there is an error of a few millimeters, but please be careful when interfering with screws, gaskets, resin packing, etc.
C	Inner diameter of roll	【Same as the diameter of the cone】 This size is the most important. If the cone size is approximately 120mm or more and has a urethane edge, it is often possible to attach it without any problems even if there is an error of about 2mm.
D	Inner diameter of the edge	【C】 The space between ～【D】 is the part that becomes invisible in the case of a type of unit where the edge is pasted from the back of the cone.
