Manufacturer unknown - Woofer box (300w x 2)

This is a woofer box from an unknown manufacturer. The box is made by Ground Shaker. Box size: Approximately 800mm wide x 315mm high x 350mm deep. Maximum output: 300w x 2. There are scratches and dirt from use. Short-term sound output was OK, but high volume has not been tested. There is some lifting of the felt and some areas of the box itself that are hidden by the felt do not fit together properly. Please check the condition before purchasing.
