@headphonedreams I understand that a specific driver required a specific cabinet with specific dimensions. That's the basis of speaker design.
I'm thinking about the problem in terms of small, medium or large cabinets with associated drivers and crossovers.
We are already intuitively doing that at Hi-fi shops by offering different speaker models. However these speaker models have unknown components. I want to add transparency to the business.
That said, this measure doesn't favor the manufacturer at all. This is purely a DIY approach to speakers. You pick a driver then you pick the enclosure and crossover. The manufacturer does that choice for us already.
