I use my ears, put in a mono track (such as Don Cheskey speaking on a constant loop),close my eyes and start to turn the dial for each driver individually until it is centered. It has never failed me, and I have always had a tight as a frogs ass in water center image with very good staging detail.
I've been wondering how to fine tune my HU's T/A, I'm using the general "sedan" setting but it still feels off. I guess those mono Brubeck CD's will be of use after all. Though when you say you do each driver individually are you talking about using the balance and fad to isolate one driver at a time?
Actually to measure impulse ( time ) response you don't need a calibrated mic..
It's about receiving the impulse, not FR.. And as long as you measure with a reference-signal, or multiple drivers at the same time ( per side, to get the biggest spike ) calibration is not needed since you're measuring time and not frequency..
I use Holm for my measurements with a Tascam US-122mkII usb soundcard and a Behringer ECM8000 mic.
Nick, On my H701 I could mute or turn off each driver and play only one at a time, I believe most if not all units will allow that.
Nick O, if it does need to be fine tuned once its all turned back on then I will do a summed T/A.
Mic10is would add time alignment to his sub when competing ( up to 5 milliseconds ).
