Or in relation to price, you can see it like this:I'm actually quite impressed by the distortion performance of the cheapie GRS midwoofer. It's much better for electrical nonlinearity than say the Kali LP-6 woofer (which, mind you, is a real stinker in that regard, like their 8").
The distortion for the Kali LP-6v2 is far too high (THD of about 1% through almost the entire midrange already at a moderate 86 dB, 1 m). When you push it above background level, it will sound increasingly hazy and a bit compressed.
But then the same person says:
Speakers probably won't be much better than the Kali LP-6v2 for that little money, even though there are a lot of alternatives on the market with similar performance. With woofers for about 5 USD per speaker, you have to put up with some distortion.
That 6PT-8 as a midrange with, as you say, 15" woofer or equivalent, let's say a powerful one, plus some compression driver, there is the potential for a fun high SPL party speaker.I wouldn't have picked the 6PT-8 for this application either, with an fs as high as 94 Hz it's much more of a midrange than a woofer (and actually quite a good one at that, not the worst choice for some PA tops or the like, or in a big 3-way crossing over to a 15" woofer or equivalent).
Others have considered the 6PT-8 as a midrange, in a three-way design:

I want a cost effective passive 3-way xover to mate GRS 12PT to GRS 6PT plus "whatever" tweeter
the system would be a small (L100 size) reflex with woofer to midrange having good poer handling and hopefully a clear midrange, I'm having a lot of pain issues but wrose, sision issues so cannot see my monitor well (looks washed out to the point that light graphs in hornresp disappear). FWI I...
