After being itchy hands of modifying my JBL control sb5 subwoofer unit with other china unit drivers ... i am left with the original units hanging around (total of 4 pcs 🙄)basically doing nothing around my storage area 🤣 they actually and originally configured using tri chamber 6th order bandpass system ... i wonder if what i could come out with something different with these drivers? from the looks they dont seem to be very solid build but their sound is indeed very solid ... i am thinking of ported for these drivers but they dont seem to have very long throw ... any other ideas? thanks

You should perhaps point out, danny, that your middle image shows the two "other'' drivers that you installed in the triple chamber bandpass enclosure instead of the original four JBL woofers.
You would need to know the T/S parameters of these JBL woofers in order to design suitable ported enclosures for them.

The SB 5 woofers are the same as my Control 5. My surrounds suffered foam rot so I replaced them with new ones.
The T/S below is with the new surrounds. I don't knowhow close it is to the originals but it should not be far off.

Well, a max flat BR is ~63.64 L/48.3 Hz, so four is a fairly impressive ~254.55 L/8.99 ft^3 net before bracing, material thickness is factored in. Stuck in a corner will somewhat compensate for low Xmax.
You can try a 2-way. With a 2.5 (WWT), you'll use all four for two speakers.
To give you an idea of the woofer, check out my blog here.
The woofer sensitivity is quite high, so choose a tweeter that can match it.
