What Time Delay Settings Do You Use?

[sl33py]

I've got a JVC head unit where I can put in the time delay from each speaker to my head. I've just got front splits and a sub. The splits are set fine IMO, but I don't think the sub has ever been spot on. I've dialled the sub so it's only handling 53k or lower (40k if I want it really tight, cos it's a 12"). But I'm still not sure what distance (cm) to set the sub for. It's in a box about 10cm from the LHS of the boot, with the cone facing the right hand side of the car slightly angled up (it's bolted down). I think the "as the bird flies" distance is about 260cm, but it sounds better (I think) somewhere between 130-150cm. Strange.

What do you guys/gals use? I'll keep experimenting, but think there maybe some trick when setting the sub distance, as it's not direct line of sight and not facing forwards or backwards.

If it is angled up, then you are going to have to figure out where the wavelengths go and do some awesome maths

Trial and Error will take less time...

When you change the space on the sub, does it delay the other speakers? Or put delay on the sub? Cause if it is delaying the sub, you're going the wrong way... The sub is further away and needs to come on before the other speakers a tad bit in order to make it to your ears at the same time...

Though in a car, this feature is kind of useless... sound travels pretty fast, this is normally left for large home theatre rooms...

The actual number I'm putting in is distance in cm from the driver's ears. So because it's not as straight forward as the front splits, you're probably right - trial and error. Just thought there might be some trick to it before I go buggerin' about with the stereo like rainman

It actually cleared up the sound with the front speakers noticeably! I was surprised. I guess I'd say the imaging got better, panning effects and stuff were clearer.
