Brand: Pioneer
As an exclusive product, the Pioneer C3 speaker does not have a specific model number or product line attached to it. This means it is a custom-made speaker that has been designed specifically for a particular application or product. It is possible that this speaker was created for a limited edition or special project that Pioneer worked on in collaboration with a specific client or partner. As an exclusive product, it may not be available for purchase separately and instead, may only be found in the intended product or application for which it was designed.
