View Full Version : help on volumen and qtc

02-13-2003, 05:34 PM
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,

i don't remember the url :confused:
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......... :rolleyes:
