Someone who is familiar with winisd or something like that, would you be able to give me a good starting point for the box for this sub. I just need box size, and tuning frequency. I'm looking for a 50/50 split between SPL and SQ. Thanks


Avalanche 15 Specs
Fs 15.7 Hz
Qms 3.5
Qes .334
Qts .305
Vas 300.6 L
Re 3.2 ohms
Znom* 4 ohms
Xmax 27 mm
Sd 749 cm2

Vd 4.04 L
Pnom 800 watts
Le 2.4 mH
Cutout 14.125"
Diameter 15.5"
Depth 7.875"

 

How do you determine by listening whether the split is 50/50 SPL/SQ or whether it's 60/40?

 

I meant that I don't want a box tuned at the res frequency of my car, but I would also not like the box to have to sacrafice a lot of loudness in order to have a perfectly flat response curve. In other words, I want it to have a mix of loudness, and good sound at the same time. Pretty much your typical daily driver. Does that explain it a bit better?

try 2.5 cubes +basket+port tuned to 25 hz, should have decent output and sq and fit in a cav's trunk and you will still have space to put stuff in . If you want to go sealed then try 1.8 - 2.4 cubes +basket sealed.

 

Try 3.77 cubic feet, with a 5 in square port by 3 in long. tuned at 46 hz. This is calculted already including sub volume and port volume

 

^^any reason to tune so high?
