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.

Rated 5 out of 5 by from Great product for a great price !I purchased these binding posts to replace old twist type terminals. Theyaccommodate any gauge wire with a solid connection, very easy to install, andprofessional looking for a reasonable price. I highly recommend these terminals for any speaker project.

Rated 5 out of 5 by from Absolutely PerfectI've used these binding posts in multiple box builds for customers. In fact, it's my go to for speaker connection and what I recommend to all my customers. I explain to them the many benefits (build strength, loss-less signal, airtight, multiple connection options). Then I show them in action. I've used these in my own builds and I believe the best feature is that they are re-usable. I've used the same pair on my own personal system in 4 or 5 boxes (I tend to go through boxes quite a bit). They have zero wear or tear on them and allow me to use various styles of ring connectors, forks, or banana clips. They're easy to carpet and paint around. I love them and will continue to recommend them to aspiring builders, DIY enthusiasts, and my customers.

Rated 5 out of 5 by from Klipsch Heresy transformed.Great company with a focus on customer satisfaction. The gold plated speaker binding post are very high quality, easily installed, and the price was very reasonable. I recently purchased a vintage pair of Klipsch Heresy speakers and these posts allowed me to set them up with vertical passive bi-amping. This type of bi-amping uses two stereo amplifiers, one for each speaker as you would mono blocks. Except with stereo amps one channel of each amp drives a woofer, and the other channel drives the midrange and tweeter. With this set up the woofer is essentially removed from the higher frequencies signal path. I've heard it said the Heresy can be harsh in the upper frequncies, bi-amping has turned them into another speaker entirely, so much more musical. But the Heresy is still a little light in the bass so I'm also using two Dayton 12" subs in stereo to fill in the lower registers. This set up really rocks with all types of music, if you've never used subs in stereo then you don't know what you're missing. If you already own one sub, then buy another and connect them as a stereo pair. Place them near your main front speakers for proper time alignment and be prepaired to be blown away.Martin

Is this a replacement for a Klipsch AW-525?

I have a Klipsch AW-525 outdoor speaker with a broken binding post. Is this a suitable replacement?
Asked by: Jerry C
These will work for any application that can use a banana plug or standard binding post. They are good and solid, with no practical current limit.

Will .25" female disconnects work with the solder tabs?

Asked by: von Ah
Yes, the included solder tabs are sized so that a standard 1/4" female crimp connector will mate with it.

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?
