The volume of your sealed enclosure design is around 7 litres or 0.25 cu ft.
That should be satisfactory. Obviously you must tweak the dimensions of the box to match the dimensions of the driver - so maybe a touch deeper.
The mounting hole size is indicated on the driver diagram as 72.5 mm. The circle diameter for the screws to front mount the driver is indicated as 83 mm.
P.S. I presume you to be quoting internal dimensions.

So when ever I change one of the parameters (height width depth) I should make sure that the Volume is at 7 litres?If the depth is increased, then the height should be decreased to a figure that keeps the internal volume at 7 litres.
Volume of rectangular box = height x width x depth
My calculator suggest the new height should be 105 mm.
The problem is how to attach it to the box, since it has a non-existent frame. Probably it's meant to be mounted from the back
Stop press! Looking at the driver photograph , I agree with pico that rear mounting of the driver would be necessary.
This means that the back panel of the box must be removeable so that you can mount the driver on the rear of the front speaker board or baffle.
It's not clear what the diameter of the opening should be, so I'll have a further look at that.
The alternative is to choose a driver that is capable of being front mounted on the baffle.
Here is a photo (courtesy of member hm) showing the driver rear mounted.
EDIT: Regarding the cut-out diameter for rear mounting see next post.
That's OK.connect the driver from "the back" and only after glue the box
Because that's the volume you chose to use in post #14 and it seems reasonable to me. I don't know what the optimum sealed volume is for this driver.regarding the 7 liters volume of box. Why this particular volume?

"...I don't know the optimum sealed volume for this driver." Gotcha"...sealed for a Qtc of 0.71 response, One liter of volume. Because the efficiency bandwidth product is steeply oriented towards that of a vented larger box, there is no bass performance at all...the "bottom-end" rolling away at minus 3.04 decibels at 179.77 hertz.

music. Mainly female singing specific musical noteI don't think the OP has made it clear whether these gallery speakers are intended to project music or speech.
Edit: regarding the screws needed for mounting the driver is it should be 4M or 5M is not so obvious (at least for me) from the Datasheet
1 litre is very small isn't it?The lowest female voice frequency is 165 Hz, so you might just get away with a 1 litre sealed enclosure.
using this calculator and entering my previous dimensions of 105 75 90 the calculator show volume of 0.7~ and not 7~
regarding the screws needed for mounting the driver
The diameter of the head of the screw must exceed 4.5 mm.
