Thanks. Mine look just like that but no tilted baffles, so they must be unoriginal. I haven't been able to find any passive radiators for them, so I thought of just putting my four 2205 woofers in there and the horns and tweeters on top of the cabinets, to avoid the HF problems from the overhang, that you desribed on a another forum. Just still wondering if they should be in sealed boxes or vented. Good thing I can try sealed first and vented later.
