That tie piece #3 is going to interfere if you put a pole cup in the top of the cabinet.  You either want to make it deeper or put two small ones in parallel.

Or use the 25mm threaded ones.

Thanks Bill, Stephen and Rob.

I think I know the answers to the below 2 question and it may have been already answered. Just need an affirmative from someone more experienced than me for the below -
1. Only the 2 port pieces on each corner behind the baffle need to be exactly as they are?
2.Rest are just braces to make the cabinet stronger and to avoid resonance?

I have a fair idea now after looking at many BR cabinets and how they are internally braced, so I think I now have that covered. (If the above 2 are yes.)

@Rob- yes still on my mind. Just did not get time to visit local stores. Will visit in a cpl of days to see if threaded poles are available.

I used pole cups and mounted them just to the left and right of the top brace on each sub for a mirrored pair.

And yeah JohnGeorge if you are building this particular cab you don't want to change those port pieces.
