308p measures better generally than 305p and is more capable in all areas that I can remember, but I imagine the 305p would be ok with the right EQ (it's not as flat as the 308p). Don't know anything about the KRK's, you'll have to see if they've been measured by Amir here on ASR, I've not looked.
Ah, I see! I'd hold off on buying the sub, I'd get in your speakers first and see how well you can optimise them - you might find you don't need a sub. Re subs, when I looked into it and bought mine I came to the conclusion that SVS SB 1000 Pro was about the best value performer out there with bass down to 20Hz. Take a look at the recent subwoofer test thread though (it doesn't come top, but it costs less):

I don't know what JBL's plans are for the future. Have you looked anywhere on internet to see if there is any information on future plans for new products within JBL?
HiHi ! thank you so much for your always excellent reviews I think that people usually despise the truth And the hard and sad truth comes often from measurements
what better evidence of a poorly performing woofer ? the very weak point of these types of speakers is often the woofer
Low THD amps are not a problem ... like low THD tweeters when cut below lets say 2 kHz
But good woofers (i.e. low in THD) are usually very very expensive and cannot be used in speakers sold at a low price point
I am more than sure that this speaker modded with a better woofer could sound fantastic
Woofer has to deal with the lower and mid range where most of the sound is
i would like to add only a comment
Just a loose thought: I wonder how much of this THD is "amplified" by the cabinet.
Old post but the center of your room is ground zero, in the literal sense, for bass nulls. Bass response in rooms is position-dependent. You can take measurements and do the math or just move them somewhere else until you find what you like.
In 2020 I bought a pair of theses and one of them has this behavior. A drop around 1 and 2kHz and peak in distortion - both were easily audible with sweep signal and some songs mainly when playing in mono. This unit was send for repair and it was a pain in the ass to make JBL accepted it as a defective unit. I literally had to measure and do some blind tests in front of their repair team to prove that unit was different enough to be considered defective. A funny thing is none of them said they could hear these. I don't know if they really couldn't or were just pretending.
Strange that you had to convince them with blind tests, because I would have thought all they need to do is measure the speaker, and if it's not coming up to spec then they should do something about it. There is a little bit of a dip at the crossover point (at about 1500Hz), but I guess you're not talking about that.
I thought that measurements were enough but they said it had to be audible to be considered a defective product. They were so unhelpful that I had to taken both speakers to their place and compare them with measurements and the infamous blind test that they did to me.
Not very good customer service! Thing is though, how long is the warranty on this product and it might differ from country to country? If it's out of warranty then they don't have an obligation to repair it anyway.
Not at all
