Which advice to follow? 2 DC LVL 5 12's

[Seth]

Hey all,

 

I'm trying to come up with a box design for 2 DC LVL 5 12's on a Crescendo BC6k. My goal isn't a high-tune for SPL/comp as I absolutely love the low notes (mid/high 20's and low 30's).

 

Just not sure whose advice to follow as I've been looking through threads for hours and the 2 main things I'm seeing are: 1.) With high power, too little Port Area (and port area per foot) will lead to output loss & port noise AND 2.) too high port area will lead to premature mechanical failure at lower notes.

 

With that being said, I can design a box but it causes me to make my box much bigger (working within a trunk) to account for the mid-30in long port to satisfy the minimum Port Area from Triticum's calc. If my main focus is "ground pounding lows", should I just stick to the "12-16" old rule to prevent overexcursion or am I going to end up with too much port noise?

 

Attaching a pic that shows how crazy long this port is going to need to be and still not satisfy Triticum's calculated values (64in^2 PA min, 20in^2 per ft).

 

My current setup is a DC XL 15 on a Crescendo BC2000d and the box I made for it is definitely lower than what the calc values should've been and yet it still performs great so I'm just confused on what to follow.

 

Thanks in advance,

Seth
