I've got this piece of 16” PVC pipe that I procured with the intentions of building a sonosub. Here are the photos: Photos are here. This piece is currently 46” tall and weighs +/- 150 lbs. As you can see, it has a “bell coupling” on the bottom that is 17.5” in diameter. Ideally, I was thinking of building a bar-height cocktail table with a marble top that would sit behind my livingroom “sweetspot” for additional people. I fully expect the table will get lots of use. Otherwise, it will be a water heater in the corner. That would mean a Shiva/Dayton DVC 12” with bottom porting. The current gross volume is +/- 162 liters. Power by either PE 250 or a Crown Pro amp from my LFE channel. I do not have a terribly critical ear, just one that appreciates good bass. Room size is 21’ x 15’. Movies 80%/Music 20%. 1.How practical is it to use this piece of PVC pipe? 2.Should I abandon the PVC in favor of real sonotube? 3.Is it practical to think this could be a cocktail table considering vibration? 4.My research indicates this enclosure volume is fine for the 12” drivers I’m considering. Agree? 5.I’ve got an open mind, any thoughts? Links work for now!
