Thank you for the add.
My friend had a phone call from the owner an old cinema, this is what he was given. It will fit in quite well into the man cave/ mini cinema he has built.... Even if it does take up most of the room.
If someone could shed a little more light on it and if anyone knows what mid and hf would go with it would be great, thank you.
Just looking at the photo's it does look like there was a rear panel which is now missing.
