4 Pcs Audio Speaker Terminal Connectors, 4mm Banana Jack Adapter Binding Post Amplifier Speaker Terminal in-Wall Plate (2 Red + 2 Black)

Ok

I bought these to replace the terminals in a Polk T15 bookshelf speaker that I dropped. It took some doing to find 4 mm posts that fit the plate that the T15s are fitted with, and these fit that bill, and work as well as the unaltered companion speaker. The only minor issue is that the posts are a little wobbly/bendy, at least with heavy gauge wire and real banana clip connectors, rather than bare wire. So, I wouldn't necessarily recommend them for large gauge wire use or with speakers that are gonna get moved around a lot. But they were easy to install, fit, and work, for a very inexpensive price.

I replaced a broken terminal on my Bose 251 outdoor speakers, which these fit perfectly. The originals looked to be of lesser quality than these replacements.I would recommend this product.

It's different from the pictures in that it's not serrated which is why I bought them originally

They were quite compatible to the ones that I had to replace them with. Perfect match.

Great value for the money

Work fine on the Bose 251 outdoor speakers.

These terminals look gorgeous and are very well made. They are large enough for the cut-outs on imported amplifier chassis.
