How To Build "The World's Best Speakers" - Are Flat Panel Speakers Really Any Good?

Подробнее о видео

Flat panel speakers built from foam boards and Dayton Audio exciters can't really sound good, right? Over on @TechIngredients they shared a design for "The World's Best Speakers". I just could not believe speakers made out of a $5 piece of foam board outperformed many bookshelf speakers, so I decided to build them so I could hear them for myself. While I'm not sure that they can rightfully claim the title of "World's Best", they are very good, and very cheap to build.

As part of the preparation to do a follow-up video on these panels, I build an inexpensive binaural microphone and added acoustic insulation to my walls. Here's how:

The full set of speakers from Tech Ingredients includes a total of 8 different panels, using different materials, shapes, and sizes. I elected to build just these 2 panels as a way to dip my toes in the water of DIY speaker systems and to see if their claims could possibly be true. The foam boards each cost me around $5, and the exciters were around $25 each. I can’t believe the sound quality I’m getting out of a set of speakers I built in a few minutes for only $60 in parts!
