We only the offer DIY kits “as is” in their original tried and tested forms, as they were designed and intended by Mr. Troels Gravesen.
The kit versions outlined in the kit presentations and listed in the DIY kit configurator are the only options for purchasing a DIY kit.
We do not have the time or resources to:
- Design custom crossovers / speaker system for a random set of drivers
- To re-design crossovers for both newer and vintage commercial speakers, other than the ones already featured in the DIY kit configurator
- Re-design the crossovers to work with other drivers than the ones specified in the original DIY constructions by Mr. Gravesen
- Significantly alter one of Mr. Gravesen’s construction to a customer’s special wishes
There are multiple phases in designing or re-designing speakers.
Using a driver manufacturer’s data in a software simulation is only the first step of many, which are required to properly design or re-design crossovers.
To properly tweak a crossover / speaker system design, you will always need to have the drivers mounted on the actual baffle, make measurements of amplitude, phase, and impedance.
Then the data must import into simulation software to generate the crossover and make test crossovers to measure/hear if things work out correctly.
This means that a speaker design process requires the designer to have drivers and the actual baffle in-hand in the workshop, making it an expensive and time consuming process.
