Some second thoughts... (Drive Units)
Thinking about it a bit further, in the past I did build something similar (much smaller though) but then with the pipe length tuned to the resonance frequency of the enclosed volume wherein the bass driver is mounted. A factor 0.7 lower.
This works like a sort of reflex enclosure but then going deeper more effectively and more even in frequency. Nice principle for 6 or even 8" woofers to keep the size a bit down. More effective (after damping it for flat response) as the tube as shown in the article.
The tuned pipe didn't need much damping material...
I would go for your Singular idea though.
Ciao,
Bert
