I still don't get it why is it so hard for some people to realize that there's nothing wrong about measuring loudspeakers with as much accuracy and detail as possible. It's the right way to quantify their performance as transducers. Also the right way to identify flaws. If it can't perform well in playing test tones (the language measuring equipment understands), chances are it won't perform well playing music. But to one's ears it just may seem to.
When it comes to listening tests, much better way to identify flaws is by listening in mono. If no major flaws are identified, and your budget and wife allows it, then go ahead and buy a pair and enjoy your music like the rest of us do. Even
@amirm owns a pair or two...
Oh, and there's nothing magical about stereo. It's just a bit dodgy way to take an actual performance to the comfort of your room. Take one speaker that measures good, pair it with another one, set it up properly and you're good to go. If they don't sound good to you in stereo, then usually something's wrong with your setup. Don't blame it on the cables or connectors, just check if they are tight.
If you suspect your electricity is dirty or flawed, go ahead and measure it. Don't lick it, don't taste it, don't listen to it. It operates much quicker than any of your senses. Measuring equipment at least makes you being able to see it. Or your amp for that matter. It just drives your speaker back and forth really quickly. If it measures good, it will make your good speaker sound good too...
If you still don't get the point, here's what an inch used to be:

So, thankfully, since 1959 we can all come to terms how long an inch really is. Sometime in the future I hope, we can also all come to terms what a good loudspeaker is. Just don't wait 'till 2059.
