BTL Tuning Question

[the727kid 1]

Just picked up one my BTL motors, plan on getting another soon. And I am working on a new box as well. I will be giving a Sundown3000 to each BTL, my question is can I safely tune the box low? I wanted to tune around 29-30hz but I have been told tuning that low with that much power on them is not a good idea.

just be careful with that much power and that low is what i was told.....

if you know to setup your amps and build your box right and know what type of stress to look out for on your sub, then it's fine.

Meade is running 4kwrms per btl tuned at 30hz so it's not impossible.
