...I highly doubt it 
I'm not very knowledgeable in this field, but my dad, who is a BIG audiophile, back in 1995 invented this "Multi-cone type loudspeaker" to satisfy his audiophilic urge. When he dedicated all his leisure time and money to earn his patent, he promised that he would make a big fortune with his invention. However, since '95 he wasn't able to find the right sponsor and he pretty much gave up on it. I feel really bad for my dad because it seems like all his hardwork is in vain and his patent is just rotting in the US Patent Office archive. Since I have no knowledge in this field, I want to ask you audiophiles if my dad's invention would have any commercial value today.
Since google has fully uploaded all of the patent archive, I have a direct link to my dad's patent and you guys can check it out:
