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 5 out of 5 by from Great Binding PostI have used several pairs of these and could not be happier! Highly recommended. I have also used 4 pair of the platinum ones and am equally pleased. They are better than the ones that come on the $2000 Polk LSI speakers.

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 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

Rated 5 out of 5 by from Very well built with some replacement OEM use.I originally bought two pairs of these for my TC Sounds EPIC 12 project. They worked extremely well with the 10AWG speaker wire I ran to each subwoofer. I eventually downsized to a single sub, and forgot about the extra set of binding posts I had in the closet. Recently picked up a pair of Bowers and Wilkins DM600 S3 with a single missing binding post screw-on tightening cap. These binding posts supplied the piece. Same size, color and threading. B&W wants like 25 bucks for a single post (understandable, they are a speaker company, not a parts company), for the price these are a steal. Other B&W's use them, all the way back to the old 500 series. Some Wharfedales and Boston Acoustics also interchange. Thought it might be helpful to know!

Rated 5 out of 5 by from Heavy duty and nice-looking!No disappointment here. They are very heavy duty and they look really sharp too. No problem installing and they should carry any audio amp load you can send to them. I'm pretty certain they could carry enough current to jump start my car. Excellent price-point.

Rated 5 out of 5 by from This is it! Follow the instructions and enjoyI used this to add binding posts to a 18" PA style subwoofer cabinet. I drilled through the wood, added these (trying to space them for banana plug use) and then glued on the inside with some Gorilla glue (it expands as it dries, so it fills in any cracks or imperfections, especially with particle board.)Once bolted up, they have a nice positive feel to both unscrewing and tightening. They look great as well. Highly recommended. I'm sending 1200 watts through them via 10 gauge cables to the sub, and I'd be confident sending double that.

Rated 4 out of 5 by from Great upgrade binding postsI used these on a set of JBL L-36 Decade speakers, they sure work better and look nicer than the originals. I had to use washers because they were going through thin masonite but the washers shimmed out the thickness and allowed the posts to tighten up.

Rated 5 out of 5 by from Excellent Binding PostsVery nicely made binding posts. These work very well and are deep enough for 3/4" material (or perhaps even more, though I haven't tried). For those having problems with the hole size, just drill a 1/4" hole (use a drill press if you have one to ensure it's perfectly straight), and instead of pounding the post in, use the nut on the back side to pull the post on. It will get pulled into the 1/4" hole just fine without much effort and no damage to your speaker or the post. Just make sure that you align the post so the bare wire holes are lined up. Either straight up and down: || or at a diagonal so your wires look good: \ /

Rated 5 out of 5 by from No Hassle and All PerformanceI used this set of binding posts on a fiberglass subwoofer box. Was difficult to get the right size hole in the fiberglass so i had to seal it with silicone. Not the product's fault but an important thing to remember. A little hard to really crank tight, I had to use a small screwdriver through the bare wire hole as a wrench to keep it from slipping. A hex head would make this easier without the risk of damaging the part. Overall great product for those making their own enclosures. Easily handles the 1000W amp.

Rated 5 out of 5 by from Good Binding PostsI am refurbishing a pair of Genesis 2 speakers, and had to replace the broken original spring clips. These did the trick. They are very solid and well made. I made a new plate to mount these on out of 1/4" MDF. I did have to add a washer to the inside as they would have not tightened up properly without it.

Rated 3 out of 5 by from Be aware - these posts are thicker than standard postsI purchased these based on the many excellent reviews here on Parts Express to replace the cheap plastic 90's binding posts on a pair of Apogee Acoustics Centaur Major speakers. Turns out the bolt end is 1/4" in diameter, which is thicker than your typical binding posts. It wouldn't fit through the back plate and none of the spades would fit. The BPT-38G turned out to be a perfect replacement, although I did have to get some faucet aerator washers to insulate the back side and the plugs still rotate if you try hard. If these came with a thinner rear bolt as an option they would be perfect, as the actual binding post on these is better, but the BPT's work perfectly with banana plugs (less so with spades).

Rated 4 out of 5 by from Beware your 1/4" hole in BB - may be too tightI have used 4 pairs of these now in 1/2" Baltic Birch. The instructions say to drill a 1/4" hole and tap the knurled shaft in. I understand that it must be tight in order to create enough friction to prevent from twisting, but 1/4" is certainly too tight.I felt like I was in danger of blasting through the plywood. It I could not get it in without loosening up the hole a bit. I expect that MDF would give to a few good hammer swings. If you are using BB, I recommend a test hole to get your size right first.

Rated 5 out of 5 by from good qualitythey do their job!! just make sure you drill the holes straight or the binding posts will be crooked
Date published: 2011-05-21
Rated 5 out of 5 by from A little expensive, but totally worth it.These binding posts are of the highest quality. They have the ability to conduct huge amounts of watts, and still work great even into the lower watt regions (think less than 10). Simple to install, although if you don't measure exactly where the holes should be drilled, it will end up looking kind of silly from the back (they will be off-center). The only con is the price, but it's totally worth it in the end when the posts outlast the actual speakers.Also, some people were saying that you need to drill a smaller hole for these to fit. I drilled a 1/4" hole, and I had to literally pound them in with a hammer (use a block of wood in-between if you do this, of course). It really comes down to what type of wood and what type of drill bit you are using. I recommend starting with one size smaller, and then if it won't fit at all, move up to 1/4". You want a really tight fit with these things so there are no air leaks.

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
Hi, Jerry. We don't carry any Klipsch parts, nor do we have a cross-reference by brand, model, or anything of the sort, unfortunately. However, if the mounting area for your Klipsch's binding posts is between 3/8" and 1" thick, with a 1/4" hole for the post(s), and you have at least 1-1/2" of clearance for the rear bolt, these should be suitable for the application.
