When the South African Radio League launched the initiative to have antenna regulations changed to facilitate the erection of antenna and antenna support structures, the South African Radio League Council indicated that it would be a long drawn out process

What you're basically saying is you left the design work to someone else. What you produced was a concept.
The actual specification of the drivers - and how a crossover etc is achieved - are vital to any speaker design. As indeed are more mundane things like the choice of cabinet materials and how that too is constructed and treated acoustically.
To get such things even vaguely right costs lots of research and development time. As you'd know if you looked at the design history of accepted good speakers.

/////////////////////////////////////////// Japan Records Huge Sunspot Cluster 66 Times Size of Earth:

TOKYO, Nov. 20 (Xinhua) -- Japanese space probe and observatory have recorded huge sunspot activity with a sunspot cluster 66 times the size of Earth, the Asahi Shimbun reported Thursday. Images of the sunspot cluster were released by the National Astronomical Observatory of Japan (NAOJ) and the Japan Aerospace Exploration Agency (JAXA) on Wednesday. The solar observation probe Hinode and NAOJ took pictures of the sunspots on Oct. 16-30, before the sun's rotation obstructed the view. The sunspot cluster could be seen again on Nov. 15, but it had shrunk to one-third of its peak size on Oct. 26. Sunspots appear in big clusters when the sun is most active. Large solar flares, a phenomenon triggered by sunspot activity, were also observed on the surface of the sun on six occasions in October.

For several residents of Coombs Street in Napa, Jeff Hullquist is their least favorite neighbor - or rather, the 55-foot-tall antenna outside his house is. Since the longtime amateur radio enthusiast raised the spidery metal mast in April, some homeowners have attacked it for spoiling their views, and others claim the antenna has even disrupted their electronics - or, in one case, disabled a woman's electric wheelchair. But their efforts to fight the mast in their midst has bumped against federal law Hullquist argues protects his right to build and use the antenna, even without a city permit. On Thursday, the city Planning Commission granted him a use permit for the ham radio antenna - but with limitations including a requirement to lower the mast to 21 feet between 6 a.m. and 6 p.m. to avoid intruding on his neighbors' views. (The city allowed an exemption to transmit during a local emergency.) Hullquist also was barred from operating his transmitter while the antenna is retracted. Afterward, Hullquist promised to appeal his case to the City Council - which also is scheduled to hear a counter-appeal from an opponent of the antenna. The decision continues a seven-month stalemate pitting Coombs Street homeowners - who say the antenna also disfigures the Napa Abajo-Fuller Park Historic District that includes the street - against Hullquist, who has argued a Federal Communications Commission memorandum from 1985 blocks cities from passing laws that make ham radio use impossible.
