Outside dimensions are 182mm x 108mm x 78mm, with 4mm walls. Attached winISD graphs are shown at 10 watts. Then it should start getting some boost at 270hz from the front resonator, then get a massive boost at 360hz. It should perform very much like a vented box made of just the back part for the lowest two notes no excursion problems at 150hz, possible excursion problems at 198hz (exactly the same as my best effort basic vented box design, fwiw). The back chamber is about 2/3 of a liter tuned to ~155hz, the front chamber is about a half liter tuned to ~360hz. It's designed to be as loud as possible while minimizing excursion across the test bandwidth as much as possible. Happy to save to older versions of Sketchup if needed, or download an older version that can export STL. I am using Sketchup Make 2017, which I had assumed was 'v17', but didn't see any way to export to STL. I've designed a a large 6th order parallel bandpass box using winISD and Sketchup.
