These terminals have replaced with plastic clamping bushes with me. Write speakers already ... the flush-mounted boxes should have been nice just used so that the terminals sit straight on the wall later. This is technically simple but determined by the holes and not a flaw. My supplied connection iris look exactly as stated in the article description / image. Font (Speakers / + and - signs) engraved black and not glued. The banana plugs go quite pure (through hole). Speaker connect with 4mm² was not a problem. The connection terminals were delivered screwed even with my slightly loose, but even that is not a problem because you facilitate (Recording cross holes) behind in the assembly as well as slightly different from each other revolves around the push through the cable. After that tightens the connection sockets and is good. Whether larger cross-sections go I have not tested. For me, the surround back speakers attached to the terminals. Beautiful Connections at a reasonable price.
