BASSER speaker rings are manufactured in Poland. In their production, we use best quality MDF's of well known brands.

Thanks to rigid construction our MDF rings guarantees best quality sound from the speaker. We don't impregnate our rings during production process, that's because it would make future working difficult. We recommend to impregnate the rings to protect them from wet after proper fit. To do that we suggest to use thin wood preserver, underbody chassis protection spray, or silicone.
