Intended for customizing speaker enclosures, this recessed panel is ideal for any cabinet or panel application.
I ordered a pair and put 2 Speakon NL4MP connectors in the cup. Works great. I recommend using some weatherstrip behind it when you mount it to keep it air tight. If you're doing 1/4s, its not as important since these jacks leak air anyway.
Very fast shipping. Great prices and huge selection of products. I love this place.
