I bought a pair of these in hopes of running one to each side of a 3 way front stage just to find out that the "sub channel" is just that. The LP filter is not defeatable, so it only plays to ~125hz... needless to say, these got pulled almost immediately and replaced with a pair of RA40. These are about as like new as possible as they were only used for ~ an hour during tuning before realizing the issue. Asking $350 obo- price includes shipping.
