Product Details

Dayton Audio BPA-38G HD Binding Post Pair Gold

The Dayton Audio BPA-38G heavy-duty binding posts were designed with the audiophile in mind. Quality, 24kt. gold plating assures the highest possible signal transfer and resists harsh environmental conditions that cause performance-robbing corrosion. The BPA-38G binding posts can be used with banana plugs or will accept wire up to 8 gauge, and large diameter knurled heads allow positive finger-tight connections.

An extra long rear bolt (1-1/2") facilitates mounting in speaker cabinets with walls up to 1" thick (3/8" minimum thickness). To install, simply drill a 1/4" hole and gently tap the binding post in place. The knurled shaft will keep the post from turning, and also creates an air-tight fit. Overall length is 2-1/4". Sold in color coded pairs with solder tabs.

Rated 4 out of 5 by from Great connector but be careful of cabinet thicknesThese connectors are great quality and look great. However the nut does not screw all the way down to the base of the connector, so your speaker cabinet walls must be sufficiently thick. I was intending to install these on a crossover panel that was less than 1/4" thick so I had to return them.

I found this is slightly attracted by magnetic. (I know nut and washer is made of metal, I'm saying body and solder tab). Commonly, these connectors are made of copper or brass. And none of two are non-magnetic. What material is used for this item?

Do these accept banana plugs?

Will these work in the Dayton Audio BPP backplate?

Asked by: KevinMc
Unfortunately no, these are only designed to be mounted into a 1/4" diameter hole in the cabinet material.

What size is the threaded part of the post? I want to use this with ring terminals. Will 1/4" ring terminals work?

Asked by: Mikeyo1
I can answer half your question! I used crimp 1/4 ring connectors for mine and they worked very well. I found it helpful to put a little weak threadlock so the nut wouldn't back off, but the ring connector fits perfectly. I actually used Elmers glue rather than a "real" threadlocker and it has worked perfectly for the last 6 months. The threadlocker probably wouldn't be necessary on applications that won't shakes around as much as my TC Sounds sub box. The second part of your question I cannot answer without measuring, save for telling you it's slightly smaller than 1/4" to as to facilitate sliding into the 1/4" hole in front of the part that grips, but still fits the ring connector snugly. Maybe 7/32ths?
