There is realyy no justification of calling the OP names. No one is forcing you to read the tread. (Clockwork Orange) That is why I quit after the first obnoxiuos response.
The problem with PLC
Firstly what is PLC? PLC stands for the PERFECT LOUDSPEAKER COMPANY. It is a hypothetical speaker company that would manufacture a perfect speaker and sell it to the public.
Now here is the problem with this idea. Imagine a genius somewhere invents a perfect speaker. It can do 20~20Khz with 0.01% distortion at all levels/frequencies. It is as flat as a pancake and has CTPRT or Custom Tunable Polar Response Technology.
Now he decides to put it in a plain unmarked cardboard box and put it on the market. No dealership, no marketing. Stereophile calls PLC and asks for a sample to review. PLC agrees and sends them out a pair. The selling price? $700 a pair.
The review would go something like this. ''Here we have a newcomer to the speaker industry. The PLC speaker One designed by expert tuner, Master Kenjit CEO of PLC. A budget speaker. Looks very plain and ordinary. Sounded a bit flat. Not highly recommended as it did not sound very special. But nice first attempt. Suitable for college students on a budget.''
Measurements:
Perfect from 20-20khz. We have never seen anything like it. ZERO resonances. Impedance flat as a pancake. Miraculous. But didnt sound very good, so we cannot give it a Stereophile recommendation.
Now with a review like that few audiophiles would buy it. But lets say an audiophile takes a chance and buys a pair. He listens to it for a few months and decides its not quite right...
PLC speaker does not manage to sell enough pairs to continue operating and closes down a few years down the line.
Now this is a hypothetical situation but this is EXACTLY what could happen even if the PERFECT speaker came along and put on the market. Unfortunately there is a saying which seems applicable that you should not cast pearls before swine.
If the speakers had a beautiful gloss finish, were priced at $50K a pair and was sent out to all the high end dealers, and all the youtube reviewers were paid to provide excellent reviews, then it would be a totally different story.
And therein lies the problem with perfect speakers.
You need perfect audiophiles that understand perfect sound before you bother inventing perfect speakers. End of story.
