Terminal Type

Terminal Type
Spring clip terminals work best with bare wire connections with small-gauge speaker wire, or pin-type connectors.

Binding post terminals are a sturdier, more versatile type of speaker terminal. Because binding post terminals are are threaded, you can tighten them down against the wire or connector for a tight, clean connection. The most popular style of binding post terminals is known as a "5-way binding post". This type can accept bare wire, or any of the common speaker wire connectors. Binding posts with the option to be used with banana clips are even more versatile

Spring posts are a hybrid of the two. Instead of using a thread and "screwing" them tight, they use a spring to allow the wire to fit and tighten against the terminal.

Worked Great!

August 7, 2016

Bought this to complete my first subwoofer enclosure. We don't have many decent stereo shops here locally and no one had anything like this that looked good and was reasonably priced. Worked great and was easy to install. The new subwoofer sounds terrific and everything looks professionally installed. Will definitely consider buying again.

for easier disconnection of my subs when I want to work on them
shelley w on Aug 27, 2014
It just makes good sense to go with solid connections for your sub box. It's also much easier to pull your sub box out if you need to and it's a quick connection.

What gauge wire will this accept?
Ace K on Jun 4, 2015
Best Answer: I am using 12 gauge with mine. Unless your pushing some serious power there's really no need to use 8 gauge...

What is the cutout size for this terminal?
A shopper on Sep 23, 2014
Best Answer: I was able to use a three inch hole saw for the cut out of this terminal. It gave a bit of slack around the insert part though.
