Unbranded BASS Speaker

Hi, today my speaker, which I bought for a pittance, arrived today. Unfortunately, there is no information about it on the Internet or about the company, no stickers on the loudspeaker. Has anyone ever bought anything from this company? Or does he know anything about her? Pictures of the speaker below:
