Replacement/repair part number ACC 004 B
(Illustrated easy installation guide)
Most older Genesis Physics speakers have a serious weak link in their implementation - despite using excellent purpose-designed drivers:
- The spring clip terminals on the back 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
- Some also included tweeter level switches, which are prone to corrosion and poor contact quality.
This is a pair of examples from a vintage Genesis 2, a wonderful speaker with an Achilles heel:
The ACC 004 B 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.
The ACC 004 B is built to upgrade these Genesis Physics models:
