Totally biased opinion here (as I own a pair) but I think this is a pretty good deal.
While there are speakers that measure better, this seems to be a very reasonable result (ie better than many speakers we have seen here). Subjectively I very much enjoy my pair.
As to the value, I think that this kit is
great.
First, you have to understand that to do DIY correctly takes time, but that time should bring enjoyment. I don’t count the time cost of my hobbies, because they bring me happiness and that has significant value. If you dislike the idea of building a speaker, skip it, use that time to work and then buy something pre-made using the proceeds. If you enjoy working with your hands and need a distraction from work, then maybe you DIY. Second, this kit is exceptionally friendly for the casual DIYer. Excellent instructions, very cool 3d printed crossover board, and a flat pack that is hard to mess up. I’ve built kits from several other sources and I would absolutely recommend this kit (or another from the same company) to a beginner as a great way to get started in the hobby. Third, with DIY you have the opportunity to make something unique and that has value. When I see my speakers I feel pride. They are frequently praised by people who see them (before they know I made them). This would not happen if they were the generic black or white boxes that most manufacturers put out.
