You wouldn't know if you never tried. Right? These speakers are not just about sound either.
Your idea of DIY is too simple. If you are after a sound that only suits your tastes, you need to measure, test and experiment with several values in the crossover design. The cabinet construction will take you at least half a day in your garage even if you are skilled. Let a long the dry time and veneer/paint work. Remember, unless you use someone else's design, you need to measure and test. That along will take you a weekend. When you use someone else's design, you don't know that it suits your taste. Even some of the most recognizable DIYers take months for a single project.
Simply, a "couple hours" of built time is only a imagination. You are assuming DIY is ALWAYS better. Yes, absolutely. Until the pre-made speakers bottom to a certain price point. This is one of those.
