Most older EPI and Epicure speakers have a serious weak link in their implementation - despite using excellent purpose-designed drivers:
- The spring clip terminals at the input 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.
I had an example from an early seventies vintage EPI 400, a wonderful speaker with an Achilles heel, but I must have thrown it away on my last cleanup binge, so there is no picture here.
They feature a new terminal cup (screws included) 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, fed by main runs of 12 AWG OFC wire from the terminal.
They come complete with mounting screws and installation instructions. Here are words and photos showing me putting an older version in my 1000s.
The ACC 004 F and G differ in one respect - the version for the 1000, the ACC 004 G, has a second run of input wires and terminal cup, to utilize the holes on both ends. The ACC 004 G does require some soldering to install, since one input terminal cup must be left unconnected until after the other cup and wiring are installed through one end hole. If you want, I can use quick-disconnect terminals at that location, so you don't have to solder.
And finally, a photo of the product:
