[QUOTE="keep_hope_alive, post: 7715631, member: 576029"] i use an RTA on a regular basis, not just for my car but for work. i just sold my second Behringer 8024 - was a 1/3 oct RTA and EQ. Sold it for $200, but you can find them for under $100. The replacement model is the DEQ2496. these are stand-alone and could be inserted in the signal path. I also have an older Casella CEL-490 at work I can use (was $7k new and we got it for $3k used/calibrated). It's a Type-1 measurement instrument. Casella has a host of hand held 1/3oct SLM's. It's eerily accurate. The benefit of the laptop approach is the ability to easily save and compare. I would measure each driver separately, from each seat, then measure each combination. all in under 20 minutes. then i can go back and look at the results and/or adjust eq/crossover while monitoring real-time. Also, with a 2 channel USB Mic Pre (I use the SoundDevices USBpre) you can have a mic at driver and passenger at the same time. Example, this was a tuning effort last year, mic at each headrest: without sub [IMG]http://i38.photobucket.com/albums/e128/phat_funky_beats/accord/AccordRTA_LR_midhigh_3rdtuned.jpg[/IMG] [IMG]http://i38.photobucket.com/albums/e128/phat_funky_beats/accord/AccordRTA_LR_midhigh_24thtuned.jpg[/IMG] with sub [IMG]http://i38.photobucket.com/albums/e128/phat_funky_beats/accord/AccordRTA_LR_all_3rd.jpg[/IMG] maybe my constant access to several different RTA's over the years has made me so used to using them, I don't think twice.
