One speaker will be used in each cabinet.
Your comments will reflect my final decision.
Remember, this will be used for fullrange purposes!

First thoughts, the box dimensions are all similar or multiples, that could lead to some really nasty standing wave resonances...
My suggestions ....
1) Add a 4 inch diameter port that is between 1 and 2 inches long and put it 4" from the bottom of the cabinet.
2) Shorten the cabinet by a couple of inches.
3) Mount the driver 6 inches from the top fo the cabinet.
4) Place 0.25 lb/ft^3 of fiber stuffing in the top 30" of the cabinet.
5) Place a Zobel across the driver terminals.
6) In series with the driver put a 4 mH iron core inductor (ERSE) in parallel with a 8 ohm Mills resistor. Tune the value of the resistor to taste and to account for the amp and the room.
How does that sound? What driver are you using?

OK. A little story about the box.
It used to hold 4 tens, in each box (Sealed) so, the
cabinet dimensions, cannot be altered.
MJK, The Speakers I'm planning to use are EV.
Thank you!

4 tens per box?
Just wad the things 'till you can barely get the drivers in, and use them as bass guitar cabs...
if you mean 1 10" percabinet, forget all about full-range response. 10"ers won't go that high unless you get some bizarre coaxial.
Hmm.
Maybe you could find space on there someplace to put a soft dome or ribbon tweeter... make a nice little 2-way system with really horrible response around whatever crossover freq you choose...

the rule to avoid resonance pile up is
1.616:1:0.618
or somthing similar
there is another one also. ist the greek golden ratio.

Use ratios that are irrational numbers... the golden ratio is just a particularily aesthetically pleasing irrational number.
dave
interal bracing can be used to get these numbers and break up the box into dimensions that spread resonances
you want to fix that while it is installed in that location? I am assuming the red stuff is a steel scaffolding. and the speaker is mounted on the roof of some thing.
