Space limitations can make it difficult to add bass to an R/V's sound system. Concertone created the SW-BOX4 to address that issue and provide your R/V with the low frequencies that make a 5.1 surround system complete. The ported MDF enclosure measures just under 4-5/8" deep, allowing this sub to fit in almost any location. Concertone designed the 8" woofer to work perfectly with multi-channel amp built into their DVD receivers.
If you're mounting this enclosure in a high-traffic area, it's a good idea to purchase the white grille to protect the sub.
