that is the exact design I was imagining! I was imagining this because it would reduce angles and additional volume loss by using less wood, however this design is the one where I would need to be aware of potential secondary resonances, correct? If I am understanding correctly the 1x 43" port should reduce the chances of secondary resonances. a second question- would 3/4" 3M ThinsulateTM Acoustic/Thermal Insulation AU4002-5 (20' x 60") work for lining the box? I have some that is backed on one side. if so attach it so the white fuzzy is facing the inside of the enclosure? Thanks again for all the hard work! it is appreciated!The Secondary Resonance between two different ports of the same surface area and length "should" be the same but I've seen some square ports that had some resonance that didn't show up in calculations.
Here's another version of the same enclosure without the folded port 10" x 4.25" x 44.75"...
