Default driver position in cabinet

I'm building a pair of subs - left & right channels - 10" drivers.

Internal dimensions H 664 x D 414 x W 264mm.

This is approximately 1 : 1.66 : 2.66 ratio.

Crossover about 100Hz.

Cabinets positioned 1 meter from wall with other drivers in separate cabs on top.

I'm wondering what is the ideal position for the drivers within the cabinets. I'm sure there's an ideal ratio but not sure what it is.

Can someone help me please

Every mode will be above the passband for a box of those dimensions, so it won't matter where you put the driver.

What Brett says is true wrt to the box itself, but placment wrt boundaries can have a significant effect.

Thanks for your feedback,

Does that means that I also do not have to worry about the 1 : 1.66 : 2.66 dimension ratio ?

That would be great because aesthetically I would prefer something else.

You won't need to worry about the dimension ratios with an upper limit of 100Hz and a maximal dimension of 664mm.

Not sure I fully understand what Planet10 is saying, but I think he means that placing the driver nearer to the enclosure walls may lend boundary reinforcement to some extent? Either that or positionining the driver with the box placement in relation to surrounding walls in mind to take advantage of room reinforcement.
