"The Acapella Audio Arts Spharon Excalibur loudspeakers are quite a sight. The Spharon Excalibur's stand just under 8ft. tall and weigh 1,364lbs each. Aside from the beautiful horns, one of the most unique features of the Spharon Excalibur's are the horn loaded Plasma Ion Tweeters that allow the speakers to reproduce frequencies up to 50kHz. Because there is no mass to the flame (or 'arc') that plasma tweeters use to reproduce the sound, they theoretically should outperform conventional tweeters with metal or fabric domes and even low mass ribbons. All that can be seen of the plasma tweeters is a pinkish/purple glow coming from inside the golden horn surrounding the housing. The Spharon Excalibur's are the most expensive speakers about, and what other speakers have tweeters that can double as night lights?"It's only $380,700 for the pair! Wow, I wish I could give every homeless person in Europe a knife and your address you scum-bags.
