In order to know this for sure you need to see the back of the speaker, but the image looks as if they have a seperate cap and wires going through the back of the magnet (meaning they should be ok).
Many co-axials run the tweeter wires directly through the woofer cone itself, and as such they are not very suitable to bi-wire. Those are the types that should be avoided if you want to use them as stock replacements.
JBL speakers in my opinion tend to have very nice sound quality, with very sharp tweeters and good sensitivity. Similar qualities as Infinity.
I think of them as a budget MB Quart and they will definitely be pleasing as a factory replacement.
On a side note three way co-axial models are almost always gimmicks in my humble opinion. The addition of the little "supertweeter" does very little, if anything for the functional sound of the speaker. Stick with the 2-ways and buy yourself a pizza. They use the same tweeter and that's what you'll actually hear.
