Compatible Speaker Size
These are the speaker sizes that the product is compatible with. For car speaker adapters, these are the sizes of aftermarket speakers that will fit inside the adapter.
Baffle Finish
Baffle Material
This is the material that the speaker baffle is made of. Common materials include hard plastic and foam. Hard plastic baffles offer greater protection to the rear of the speaker because the material is much more sturdy. The foam baffles are easier to install and can create a more watertight seal.
