Bass-reflex enclosure Basser B1250S Black

Basser enclosures are manufactured in Poland almost exclusively from materials sourced within the European Union. High-quality MDF boards are used in their construction. They are covered with a durable carpet that keeps the enclosure looking like new even after many years. In Basser enclosures the subwoofer will sound exactly as its manufacturer intended.
