(Illustrated easy installation guide)
I have used this part number for a few different models, that while quite distinct, use exactly the same number and type of parts in their backplate/crossover assemblies. Thus, they cost me the same to make.
The Genesis V-6, like many older speakers, has a serious weak link in its 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.
The Genesis 11, Genesis 22 and Genesis 33 aren't quite as bad, terminal-wise, but it's still nice to have proper binding posts. And better parts. And 16 AWG wire.
The G11, G22, and G33 had a few slightly different configurations - some had round, screw-in cups that fit a 2" hole, and then the crossover parts were on a small separate board glued inside the cabinet. Many others used a screw-mounted cup that fit a 3" hole, with all the parts mounted directly to it. Some later G22s used a press-in cup, which were probably augmented with some hot-melt adhesive on the inside. I will need to know how yours are made if you order them, and that is what the "Comments" box on the order forms is for.
This is a pair of examples from a vintage Genesis V-6, a wonderful speaker with an Achilles heel:
The ACC 004 E is a complete assembly I designed and developed to remedy all these issues.
It is a second order high pass filter with a "shelved" roll off. The tweeter is still crossed over at 1800 Hz, but it comes in more gently for its first octave or so.
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 capacitors are high-quality film types 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.
And finally, some photos of the product. First, the V-6 version:
It looks like I may not have photographed any of the later G11, G22, or G33 crossovers yet. How remiss of me.
