No, this is with Q=0.707so this would raise the q above 0.707 ? I worked out a 45/50 litre box would be ideal for this driver do you notice any difference in using a smaller box like this ? I have a project for a friend would be handy to be able to put a couple 15s in a smaller than the ideally suggested 300 litre box
The reason why the cabinet became this 'small' is that I assumed that the cabinet would be heavily filled with damping material (cotton wad)
If that is not the case then you would need a 137 liter box
Generally speaking smaller box = (much) more amplifier power needed to reach peak SPL (but with wad filling we can 'trick' the driver to 'think' that it is in a bigger box)
My 15" Fanes are in a 65 liter box with heavy filling so I could reach max SPL with 100W/channel
In a 300 liter heavily filled box only 20W would suffice for the same
