Enhance your DIY audio projects with the AcouZen CNC Aluminum Speaker Terminal Plate – a high-performance rear mounting panel for passive speakers, home theater systems, bookshelf speakers, and custom subwoofer enclosures. Whether you're building a new set of stereo speakers or upgrading your car audio system, this panel delivers both style and function. Crafted from 5mm thick aluminum and precisely CNC-machined, each plate features a sandblasted and anodized finish that resists corrosion while giving your speaker cabinet a clean, modern look. It's the perfect replacement for plastic injection-molded plates, offering higher durability and premium aesthetics for audio enthusiasts and hobbyists alike. Laser-engraved “+” and “–” polarity markers ensure clear, reliable wiring. Our exclusive red and black T-shaped insulating rings fit perfectly into the terminal holes to prevent metal-to-metal contact, reducing the risk of short circuits. High-quality nickel-plated flat-head hex screws (included) allow for flush and secure installation. Available in both 2-pole and 4-pole configurations, this terminal plate supports traditional stereo speaker builds as well as advanced bi-wiring and bi-amping setups for high-end loudspeakers. The mounting holes are compatible with most M8 or smaller threaded binding posts on the market. For the best result, pair it with AcouZen banana plug connectors (sold separately) for seamless integration and upgraded sound systems. Ideal for speaker builders, car audio modders, and anyone customizing passive speaker terminals, AcouZen delivers the quality and precision your project deserves.
