FTFY
I'm happy for you that you found speakers at your budget and you like them, but if you want to hang around here and be "cool", please stick to highlight that this is your
personal and
subjective opinion about these speakers "accuracy"
These speakers are accurate:

I am literally going to eat my shoes if your polk towers come anywhere even near to accuracy/flatline FR m2 has.
But as far as crispy - I don't doubt that. Polk is known to have overly enthusiastic tweeters setups and as result most of their speakers (again except top end) are typically overly bright or even harsh. Some people may confuse that with speaker accuracy. it's isn't.
I know cool place you're sure to like with same minded folks and no Polk haters. I promise.
