Why Did I Make So Many Round Speaker Housings? Why No Two Are Alike?

Its a science experiment. A research paper compared several different shapes and found a sphere was the best shape for a speaker enclosure. Thats for one speaker in the enclosure. Adding additional drivers in the same housing was not tested. Elongated teardrop shapes were not tested in that experiment and neither were enclosures for multiple drivers. These enclosures were made to test different ways of adding another driver to the enclosure, and what effect this has on the sound when measured with objective instruments. Several enclosures also test different ways of manufacturing that could speed up the process of fabricating enclosures if this has no negative effect on the sound. The process of making these tested several different molding techniques and the use of hybrid "glove molds" which have a flexible silicone rubber liner inside of a rigid fiberglass shell. The glove molds allow molding of deep grooves or narrow ridges that were impossible to demold from rigid fiberglass molds. Using a fiberglass shell around the silicone mold allowed the flexible silicone to mold parts with enough precision to work for this application. We are most interested in the effect of adding a second sphere with a second speaker, and will sound diffract off of the second sphere in a detectable way. Will raising the second sphere off of the first a bit help? Will merging the two spheres with a curvy transition make any difference? Two of the prototype enclosures tested a way of molding the front of both spheres in one mold and the backs in another, leaving a flange and will sound diffract off the flange in a negative way? And will making the flange smaller help? The end goal is to make a much larger speaker with expensive drivers that will sound better than the same drivers could possibly sound in a rectangular box. They will have to be more beautiful than the rectangular box they come in as well. And to everyone's relief, this will probably be the last video about these small, round speakers. The catamaran is gone. I have been limping around on a sprained ankle or broken heel for a week. The MacGregor is at a nearby shop getting a brand new Honda 50 that should reliably take me someplace nice for the summer. This channel can finally get back to something more water related. Parts have arrived for the mechanical dolphin, so some work can begin on that. The SeaRay ski boat had a dead battery which I replaced, but now the battery shutoff switch is frozen so I need to fix or replace that before making another attempt to turn the engine over. The engines on the Carver have not turned in years, so i will have to charge batteries before i can see if that boat gets fixed or goes to the landfill since nobody has any interest in it. I'd like to go to the Bahamas this summer if I can get my passport renewed, otherwise dry tortugas and the Marquesas might offer cleaner water than Biscayne National park where I was hospitalized with flesh eating bacteria last time I swam in the water there. The MacGregor can take me if the Carver is lost by now. In the meantime, there is a 12 mile stretch of beach north of Kennedy Space Center with no roads going to it. I'd like to try and reach it from the Mosquito lagoon using the raft or ski boat. (Yes, its really called that, and yes there are mosquitoes.) When they started launching rockets from there, the army corps of engineers dug a huge moat around the lagoon side of the barrier island there. In most places, you come ashore onto a narrow strip of land with a 20 foot moat between there and the actual barrier island. There are a few places where hurricanes have washed beach sand all the way through the moat and into the lagoon, creating a path to walk from the lagoon to the unreachable beach. I'm wondering what treasures I might find beachcombing where nobody else has been in a while.
