Real gratification comes from visualizing a new speaker, designing it, building it and changing it until it sounds as you first imagined it.
I agree, but let's not forget this is a hobby, and learning happens from all sorts of directions, as does the passion to learn more.
The DIYer who buys a complete kit, perhaps to build with their children or grandchildren is starting a journey.
I personally am always happy to see DIY efforts in Audio for a lot of reasons. I like builders more than I like spenders and people with hands on experience in building a single speaker already know more than any audiophile who merely reads a magazine.
Please, please, get your hands dirty. Encourage your daughter or son to learn about electronics, music, physics and let's all have a great time with it.
