Please don’t say “you can use the wire directly” like you’ve done twice. That is not what the question** A: I measure the hole at the top as 5/32" or 3.9 ish mm. That should work with most banana plugs but I don't personally use them with my speakers. The hole is more than deep enough also as it run from the top to the bottom of bare wire hole. **Q: Will these posts accept a banana plug?** A: It’s a yes or no question. Why do you refuse to answer the question? People who use banana connectors do NOT want to wire directly. Just say “no” if that’s the answer. **Q: Will banana plugs fit in these?** A: These are standard cups. You can use wire directly, lugs, or banana plugs. You have to realize the seller is some Chinese guys who doesn't speak English. **Q: This discription and picture are trash... why is the diameter of the cut out needed not listed? Its more important that screw spacing!!** A: It looks like it is listed it’s a three inch diameter I used them to replace the old Spring loaded Connection ,screw holes not a problem ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Buy For The Price! *by C***S on September 22, 2024* These circular speaker wire connectors are exactly what I needed to improve my sound system setup!

Easy install. Two issues. One, the terminals are super thin. Be careful when installing the spade connectors. Two, plan on buying the banana connectors if you intend to disconnect/connect often. It's a PITA to tighten the lugs due to the size and angle of the hand nuts. ## Frequently Bought Together - Arroyner 5Pcs 3-Inch Speaker Box Terminal Cup DIY 2-Way Speaker Box Terminal Binding Post Round Spring Cup Connector - Twidec/360Pcs 2.8/4.8/6.3mm Quick Splice Male and Female Wire Spade Connector Crimp Terminal Block Assortment Kit Golden with Insulating Sleeve for Electrical Wiring Car Audio Speaker N-002 - 16 AWG Gauge Speaker Wire Cable Stereo, Car or Home Theater, CCA (100 Feet) by Install Link --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/177002242-arroyner-5pcs-3-inch-speaker-box-terminal-cup-diy-2](https://www.desertcart.hr/products/177002242-arroyner-5pcs-3-inch-speaker-box-terminal-cup-diy-2) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-21*
