After getting to dial this in a little more it’s really come to life. The room this is in is approximately 18 x 26 x 8 feet
It fills in the lower frequencies without getting bass heavy or muddy, yet is still very dynamic and explosive when needed.
Playing Bassgasm by Techmaster PEB this was skaking pictures on the wall in the stairwell.
This reminds me somewhat of my 30 year old HSU SW10s.The Sonotube makes a great enclosure and the SAF (Spouse Acceptance Factor) was very high,since they make good lamp stands. But that’s not why I like them…they produce that “air shaking all around you” effect; that’s why I like them.
Really like your design. I have a theater is similar in size and I am looking for diy designs…care to share yours?
Adrian, thanks. I modeled and tuned the enclosure in WinISD. The finished sub is 34″h (w/feet) x 10.25″w x about 9.5″d (not counting connections to amp).
