Up for sale is my JBL LSR310S 10-inch Powered Studio Subwoofer. It’s fully functional and sounds exactly as it should. I’ve used it in my home studio, and it has been reliable throughout my ownership.

This sub pairs exceptionally well with JBL’s LSR and 3 Series monitors, adding accurate low-end extension without becoming muddy. It’s a great choice for music production, mixing, mastering, video editing, or anyone looking to add solid low-frequency response to their monitoring setup.
