Let's see ... on the one hand you have a speaker designed by a world class engineer and designer with an impressive pedigree. Someone who is really known for pushing the envelope when it comes to cutting edge technology.
On the other hand, you have a DIY design being monetized by a youtuber (who mind you is fairly new to the game) with zero experience in designing any speaker, let alone a world class speaker like the other guy.
That's a tough one for sure!
