Dayton Audio BPFI-G Fully Insulated Binding Post Pair Gold is rated 4.3125 out of 5 by 16.
Rated 3 out of 5 by from Non-standard hardware, unresponsive manufacturerThese are very nice, well made and attractive. Rather than the common 5/16" or ⅜" mounting hardware these seem to "split the difference" at 11/32". The description says they are "fine thread" but offers no specific TPI info. Parts-Express does not have any further info, and does not have the hardware available separately. Dayton Audio has not replied to my email asking for help.If your lose a nut, or if your planned application calls for an additional nut on the threaded portion of the binding-post better plan to buy two binding posts for each position. At that price it might be better to get the WBT posts.

Rated 4 out of 5 by from A fun projectI used these posts on a tired pair of Swan Diva 2.1 speakers in the rear of my HT. I was sick of the ugly brass binding posts and bus-bar to mate the tweeter and bass crossovers. I re-wired the speaker using only one set of these posts and I was able to achieve the desired affect. Be careful with heat as some have previously said. The plastic on these posts can melt. I managed to have no trouble with this because I was careful. I found these posts were not long enough to get through the cabinet of my speakers. I could not use all of the plastic washers that come with the posts. I was only able to use the flat washer and nut to secure them. I use straight 11AWG PCOCC speaker wire into these, it fits perfectly. These posts are able to cinch very tightly to the wire which is exactly what I was looking for. I had to dock a couple points because of the length of the posts, it's just a bit too short for a desirable size of speaker cabinet.

Rated 4 out of 5 by from Excellent Value/Quality for the PriceI've used several sets of these in various applications & they are an excellent value for the price (paid $22.50/pair). As previously stated, you have to be careful or use heatsinks to prevent melting the plastic insulator rings when soldering, but that's relatively easy to overcome.They are quite heavy, & copper underneath the gold plate. I don't recommend removing the tabs on the insulators as they keep the binding post stable when you tighten it down....go ahead & cut the tab slot into whatever you're working with.You can get better, but you're going to pay A LOT more to do so.

Rated 4 out of 5 by from Careful with the heat when solderingThese are generally pretty nice quality. I found them easy to use, but you have to be careful when you heat them to solder to the tab. If you over heat them, it is possible to cause the plastic insulation on the spade lug nut to lose its grip on the metal nut. This makes it hard to tighten the nut because the insulation slips when you apply too much torque. Also be aware that you have to insert spades or bare wire through a slot. This is no issue for bare wire, but for spades, you have to be careful what size spade you use or they will be too wide.

Rated 5 out of 5 by from Best Bang for the BuckI use these when I upgrade older amplifiers to replace the stock and usually very cheap binding posts that were original equipment. There are a few better posts out there at many times the price of these, but these look and perform almost as well. A good choice for the hobbyist updating his equipment.

Rated 5 out of 5 by from Why buy cheap posts? Excellent features,a bargain!Sure, we all hate to part with our hard earned cash, yet have you ever really been happy with those cheap posts which only cost you a few bucks a pair? I sure have not! These posts are now the standard fare on all the speakers I upgrade or build, no more cheapies for me. The main feature I have been searching for was found on these connectors which I could never find on the less costly posts. When securing a bare wire or spade lug, the clamping area must not rotate as the post is turned in order to produce the tightest possible connection. Much like a washer under a nut, this feature allows for greater clamping force over a one piece design by decoupling the rotational friction from the wire or lug when turning the post to secure the wire or lug. The insulated cover comes off easily so you can grasp the post firmly when using in this manner, and for those who only use banana plugs, then none of this really matters at all ..

I accidentally damaged the plastic keyed washer on a set of these. Are there any replacement parts available?

Asked by: Fritzy
Unfortunately no, we do not have replacement parts available. Purchasing a replacement pair of binding posts in the event of damage is the recommended course of action.

Which spade lugs to connect to amplifier?

I would like to connect the amplifier to these binding posts by using cables terminated in spade lugs. Please note that I AM NOT DISCUSSING the connection between the inner end of the binding post to the crossover or speaker driver. I am discussing the OUTER end of the binding post, where the cable from the amplifier connects to the speaker enclosure.Which of the various spade lugs sold on Parts Express can I use to connect to these binding posts from the OUTSIDE?
Asked by: tcpip
The spades need to have a fork ID of 5/16" and OD no larger than 1/2".

Which spade lugs?

I wish to use crimp-type spade lugs to connect speaker wires to these terminals. Which of the spade lugs (or even ring lugs) of Parts Express will fit on these terminals?
Asked by: tcpip
These terminate in "solder-on" gold plated tabs. I don't think you can use standard spade lugs without opening up the crimp to accommodate their thickness. They were designed for a high wattage connection to the speaker load cables. Usually soldered in place. You could use a good quality nut/bolt connection, but it wouldn't be as good as a solder job. See suggestions.

Is there a minimum cabinet panel thickness?

I have an approx 1/16" (or 1.5mm) thick panel, but cannot tighten these. It appears the plastic keyed washer is too thick - it protrudes slightly on the inside of the cabinet. Am I doing something wrong? The best solution I can think if is to sand the washer to make it thinner.
Asked by: rif314
I'm not sure that I understand your question. So we are on the same page--I hope you have inserted this 5 way binding post set, so that the tabs with the [wire hole] goes toward the inside of the cabinet. Run your wires to the crossover by soldering the wire [usually inside of the hole]. If I have misunderstood--then sand the plastic washer off a bit. These are insulated from the +/- terminals so there is no wrong way.
