What Time Delay Settings Do You Use?

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 :w00t:

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 :w00t:

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.

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
