(Illustrated easy installation guide)
Most older EPI and Epicure speakers have a serious weak link in their implementation - despite using excellent purpose-designed drivers:
- The spring clip terminals on the back are awful: they are awkward to use, only accept wire up to about 18 AWG, and often make a poor electrical connection.
- The internal wiring is fairly skimpy (20 or 22 AWG), and the crossover capacitors are the cheapest available
- Many also included tweeter level switches or knobs, which are prone to corrosion and poor contact quality.
- Most of the "double module" speakers have an impedance selector switch, with similar issues.
This is a pair of examples from an early seventies vintage EPI 201, a wonderful speaker with an Achilles heel:
The ACC 004 C is a complete assembly I designed and developed to remedy all these issues.
It features a high quality, non-resonant 1/4" thick 5" by 6" MDF backplate, with a pair of gold-plated, color-coded five-way binding posts securely attached on standard 3/4" centers. These will easily accomodate up to 10 AWG wire in the hole through the posts, along with several other connection methods.
The crossover capacitor is a high-quality film type with vanishingly low deviation from the ideal impedance curve, and the internal wires are color-coded 16 AWG oxygen-free copper with connectors that match the terminals on the drivers.
It comes complete with a built-in sealing gasket, mounting screws, and installation instructions. Also, here is a step-by-step pictorial showing how to install it.
It is set up to replace the terminal, crossover, and wiring harness in the "double module" speakers (two woofers and two tweeters) such as these:
I normally build it in the "4 ohm" mode (parallel), and it does not have a switch to change it to 16 ohm. Most amplifiers will drive a 4 ohm load quite happily. If you are ordering a pair and prefer the 16 ohm configuration, just tell me in the "comments" section of the order form.
The ACC 004 D is set up to replace the terminal, crossover, and wiring harness in the "double module" speakers that require much longer wires, such as these:
