I haven't purchased a marquee retainer yet, so I don't have all the details. I'm about to install my speaker panel into the cabinet sides and I realized that I don't know how far the speaker panel is supposed to be from the front of the cabinet (I'm assuming it's 3/4", but is that from the top of the speaker panel?) and I'm wondering how a marquee is put together on the diagonal surface of the speaker panel. Is there something I'm missing here? I'd really hate to get my speaker panel mounted and then need to adjust it later on for my marquee. Your help is greatly appreciated, as always!!
