Lol, next it will be the difference between those who can read instructions from a kit and build a speaker or crossover, and those who can order the raw parts and design their own. This forum would be a very small world if we start discounting what I’m going to assume is the majority of the people who enjoy this hobby. Do nascar fans have to race at least at an amateur level to be considered a true fan. Maybe that’s the reason why we even have. BLM movement in 2020. We keep looking for ways to exclude people rather than include them. Wouldn’t this hobby be better if more people enjoyed it? There might be more technology and more resources able to be thrown at it if there were more money involved. Don’t look for ways to divide and exclude, look for ways to engage and include.
