Rebuilding my rig can you please advice

Hi all

I am currently swapping all my rig around and wanted peps advice on this set up?

I plan to have (some of this kit I have all ready)

Per side Bass 2 ass bs 600s flat on the ground with 4 usb's
On top
My idear being that bs600 that will go lower than the usb's

Will give a good frequency response from low to around 300 hz

Per side My mid tops will be 2 Tms 3's( my Tms 3 have been split so the double 15 has been split so it's two sepeate cabs.)
Just the mid top part 2x10 and v2 each cab .
And all so 1 tse111 run active.
I think Tms 3 10 is at it's lint around 300hz
Being run nicely any lower and I guess it's asking a lot

Amps will be bass 2x crown 5000vz
Mid 3 x ppx1200 Citronic
Top 3 x Ppx450 Citronic

I will in time replace the citronics and the crowns
For some thing lighter

If I run this rig will the usb's play up to meet Tms 3s
Or will there be a frequency gap. I have told not to take Tms 3 down any lower
As this is lots of speakers I don't really want to add the double 15's in as well .
It's very rare that I would take it all out ,
But if the need arises there nothing like hit peps in the chest

Like to here your coments oh and yes I do have tail lift for amp rack thank the lord
