help on volumen and qtc

[Raul-tsv]

Hello,

i am trying to "build" a sealed box for two 12" subwoofers and i am using the winisd software for that, but i am confuse in the volume and qtc parameters...

the specs of each woofers are:

- qts 0.37

- vas 56.3 l

- fs 26.1 hz

- re 4 ohm

- xmax 5 mm

- spl 87db

- pe 1200w

- dia 11 in

- the manufacturer recommends the sealed box and 1 cubic feet of volume

when i use the program with the specs i mentioned before it displays a 1.5 volumen ft^3

for the 2 woofers and a qtc of 0.71, but when i change the volume to reach the recommended qtc between .9 and 1.1 the volumen decrease at less than 1 ft^3 for both woofers, is this correct? cause the manufacturer recommends 1ft^3 for each one

or how can i configure the parameters to build the "perfect box" for this woofers

thanks for your help,

Raul

i don't remember the url //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

but in some sites of audio themes... i found that a qtc of 0.707 is for a flat bass.........

and between 0.9 and 1.1 is better for hard bass music......... //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif
