Instructions
A detailed video series takes you step by step through the Trohet R build.
Crossover assembly is not included in the video series. Detailed crossover schematics and component layout plans are provided with the kit.
Pre-Assembled Crossovers – Optional
If you're not confident soldering and assembling the crossover networks yourself, we can build them for you.
Simply select Build the crossovers for me when configuring your kit.
Finishing
Varnish is not included due to air-freight restrictions on combustible liquids. Wipe-on polyurethane can be purchased from your local hardware store for about the price of four cups of hipster coffee.
