Im not sure if i can just give you the specs on the driver and then help me figure out port size from that or not but speaker specs are:

Re .975/3.9 (dvc 2 ohm)
Fs 19hz
Qes .271
Qms 4.59
Qts .256
Vas 143 litres
xmax 13.5 mm
spl 90.2 db

I have a box from a past project that is about 3 cu ft (subtracting driver volume already done). Is there any way I can mount these two drivers in this box (its sealed right now) then cut and install a port to make these drivers work with 1.5 cu ft of volume for each driver?

Any help or comments appreciated...

Thanks

Your box seems perfect fore two of those woofers, if it stays closed

Porting results in either a too small or too long port
