This listing is for a single Boston Acoustics VR970 12" passive radiator. I believe this may have also been used in the VR975 as well but am not positive.

 The original rubber surround had been poorly installed at the factory & had come unglued in several places. The original rubber surround stretched & tore when I tried to remove it, so I installed a properly fitting heavy duty foam surround.

 Passive radiator is in excellent working condition.

Basket o.d. is 12 1/4".
