Features
Fully custom build
Each network is meticulously hand crafted.
Pure point to point connections
No PCB and no wiring between components. Whenever possible, we mechanically connect components to each other for a superior connection and durability.
Layout
The component layout of your new networks is carefully chosen to provide the shortest signal path possible while also ensuring magnetic field contamination is keep to a minimum or non-existent. For more information on why this is important, visit our
layout information
page.
Cardas Quad Eutectic Solder
George Cardas created this ultra pure, quad eutectic solder for perfect joints; the best reliability with the lowest noise and contact resistance. Ultra pure, tin/lead/silver/copper.
Copper Connectors and Wire Nuts
Optional
- When installing your new networks, we understand that there are situations where you just don't want (or can't) solder a wire-wire connection. We offer pure copper connectors to allow you to crimp those connections. We even throw in some color-coded pre-cut heat shrink tubing to make it professional. Alternatively, we also offer wire nuts for the easiest install possible.
Substrate
All Skiing Ninja Networks use point-to-point construction techniques over painted MDF. No Printed Circuit Boards. No thin traces to contaminate the signal. Just pure, crystalline music...
Spax Screws
Spax screws are specially designed to make it easy to install your new crossover networks. Traditional wood screws only really work well if you drill a pilot hole or can apply copious pressure. Inside a speaker cabinet, neither is practical. Spax screws have patented serrations that drill their own pilot hole.
Imported from Germany.
Stand-offs
The last thing you want after installing your killer new networks is a spurious vibrational sound that wasn't there before the upgrade. That's why we include specially made 60 durometer (a measure of hardness) board stand-offs. These stand-offs isolate your new network from the cabinet and keep it quiet!
Choose Your Wiring Connections
We offer three different ways you can install your new crossovers depending on your skill and comfort level.
1
. Solder Method (Ninja recommended): Utilize the full wiring replacement wiring you receive with the GR-Research kit. We include Cardas quad eutectic solder to attach the wires to the drivers and binding posts.
2. Copper Connector Method (no soldering): The full wiring you receive with the GR-Research kit is attached to your network but we provide copper connectors with color coded shrink tubing so you can tie into the existing wires coming from the drivers and binding posts. Simply crimp the copper connectors over the wires and heat the shrink tubing with a heat gun or hair dryer for a professional finish.
3. Wire Nut Method (no soldering): Our easiest solution - The full wiring you receive with the GR-Research kit is attached to your network but we provide wire nuts for all connections. Twist the two wires to be joined together and screw the wire nut over the connection and you are done.
Difference between Copper Connectos and Wire Nuts
Is there a sonic difference between the two? Technically yes however is it audible? Not likely. Our recommendation if you can't do with option number one: choose which ever solderless option you are most comfortable with. If you are OK with either, choose #2.
