As I am playing a 12cm driver below major beaming at 2.2khz the driver is omnidirectional pretty much below 30 degrees and playing off the screen, so angle makes very little difference to the response at the listening position, it will change the drivers distance to the screen and the comb filters, but again these will be way above where it’s playing anyway
i don’t know what you mean by steer the image? I want the stage as deep as I can get with as much width as I can get… so realistically the drivers are as wide as possible with as much depth as possible in the current enclosures, you won’t make the image any wider, and making it narrower would defeat the object
but steering the image seems a little odd to me…
I hate to say this but unless you have a full car in your basement all bets are off as standing waves and reflections don’t just come from what you have there, so your effort will not reflect on what happens in a car… for example I found the limitations of the car and where drivers could play from and too from measurements of freq response in the car with drivers in various places
locations are decide by doing these measurements, as are crossovers, you can’t hear what will happen in a car from your rig… only what happens in your rig, once you add a bulkhead and panels from doors back you will have to learn the car again unfortunately
