No George, The K horn has certain advantages the big one being efficiency which is the major reason it became so popular in the first place. It does have problems that have been insurmountable for decades but now they are not. So, why not try and correct them and see what you get? Many digital electronics leave absolutely no fingerprint on the signal and once you are in the digital domain you can do all sorts of stuff without any distortion, none. I can go in and out of 24/192 all day long and you will never hear the difference. You can not have the best subwoofer system without a digital cross over. You can not make your speaker image pristinely or accurately control your systems frequency response without full range digital room control. Without the ability to manipulate your system digitally you are in the stone age. Most of the recordings you are listening are either digital or were modified digitally. Any vinyl re release of an old analog recording that magically has no tape hiss, how do you think that happened? So if I use that tech to make an old speaker that magically plays loud as hell with a 300B amp image correctly what is the big deal.
This hobby is supposed to be fun and it is always fun to consider possibilities. That is how we advance the art.
