hello all,
just a quicky...
im having a play with win isd and a project for a friend (in car) its 4x the orion cobalt 15" (co154s-see here for the specs- http://www.carstereos4u.co.uk/15-subwoofers/orion-co154s-bass-speaker-840797-296183-.php)

the box is approx 140l for the 4 subs. it will be ported-but the tune is undecided.

when i put the available perameters in win isd and select 4 drivers - it seems to give me a quite a peak at the port tune freq.

it looks good though when i put the volume each sub will have in ie the 140l divided by 4.

so do i put 140 in or 35l ??

and are the limited t/s perameters enough to be a reasonable representation of the responce (the fact that it is in a car aside)

any help apppreciated!!:T

thankyou people, it took me ages to work out why it wasnt working- in the end it was because i had win isd and isd pro-using the same driver database ect-it was all screwed up!

couldnt have done it without you- small thing to some but, big to me!

my mistake there, it was 220l not 140.....too many numbers!!!
im tuning to 24hz if you wanted to know-thanks all!!
