My life with an RTA

I agree with that statement, starting point it is great. Like I said I would definately use it to get a quick snapshot of polarity etc. For example if you have a dip at the crossover point for the subs it can indicate being out of phase with the midbass, but if the dip is at the sub crossover point and the mid crossover point it can indicate the midbass is out of phase, it definately takes some time off that part of the tuning process.

I've never used an RTA to tune my toy. But at the same time it would be nice to see how it ends up on paper so to speak. Now that I have an EQ I will agree with^^ defro ^^ and that final tuning is up to your ear or 1 of the tuners that DWVW has refered to. On an side note if I ever get the chance like I had at Memphis the Mini will be tuned by an pro! Any way befor I plug in the EQ the system is going to be RTA'd. So after the EQ is in and running I get my base line to start from. Your ears do get tired and don't allways tell you what you need to know.

The RTA is difficult to use, and it's very inconsistent (because of the nature of the acoustic field) but it can still be useful in a lot of cases, as PEI330Ci showed. And as DWVW mentioned, this only takes care of the frequency response - it doesn't take into account the phase response of the system..... but how would we do that?

if using an analog eq, you will likely create more phase issues than you could ever fix, and likely make one thing worse while creating maybe fixing another, at least using a true digital eq it wont present the phase related issues you get with a analog eq, i actually take six different printouts, in six different position(left ear, right ear, etc) off the 3055a and create a frequncy response graph, all measurement are taken with at lest myslef and perhaps a passenger
then i graph them out and make eq changes based on the six curves, its time comsuming but that is how i start after making the obvious changes to xover points etc, if need be, then its off to the fun part, listening tests
