my choices are normally kicks first, then underseats… doors are way behind and I’d not do a serious sq car with doors unless it was a freak of size and it’s nodes had a particular combination of lengths and freqs that cancelled out the other nulls, I know of one such car and I measured it’s phase response and it’s uncannily good… unsurprisingly it has been an Emma euro championship winning car and it’s drivers are placed more by luck than judgement, but it’s phase plot is super smooth upto 400… they used to cross drivers at that point, but it’s now at 350 and the staging is so much better… I also corrected the drivers midbass by 12cm and improved the impact by a good margin, small things matter!
