Welcome to the Shack! We need to know the maximum internal volume you have to work with for a sub, can you state what the dimensions are?

Are those internal measurements?

18mm MDF would be fine. For simplicity well call it 20 mm MDF. Internal measurements would be 3360 mm x 460 mm x 760 mm. That works out to 41.25 cu.ft. or 1168 liters. How far do you want to take this? You have enough volume and budget to create a real low end monster. Here's an example. A pair of IXL-18's in 800 liters tuned to 14 hz powered by a Behringer EP2500 would produce over 125 db down to 15 hz with room gain. And that's without the SVS PB13 Ultra. :blink: A pair of subs is $628.00

I'll guess a EP2500 is under $500 in Australia, and add $200 for everything else.

I found the EP2000 for $485.00 :

It can be done with a few slight adjustments to the box size.

As long as there is enough room for the diameter of the sub which is 46.2 cm. Porting is going to have to be a 250 mm diameter tube 750 mm long, preferably with flared ends.
