box help for 2 DD Audio 608 subwoofers

[Noah Lee]

Hi,

 

After people's opinions on the box I have designed below for 2 DD audio 608 subwoofers, it meets the specs of the subwoofers apart from what they recommend 38hz tuning where I have opted for 35hz for more low-end can anyone see anything wrong with this or what would you recommend? any help greatly appreciated 

 

 

cheers

What is the vehicle you have?

It is going in a Vw Transporter T5 van

In a van generally you benefit from a subs up / port back type of enclosure.
