hifi vs Logic7 vs Individual audio SQ/spl

david in germany · 01-25-2017, 01:47 AM

Has anyone ever done a specific RTA measurements of all three E90 systems? Presently my wife's 328i has the Professional CIC with Hifi and my 335i e90 has Logic 7 with Professional CIC. My plan shortly is to upgrade my Logic7 to Individual Audio and stick my Logic 7 in her car.

If it has not been done before is there any interest in a white noise RTA reading/music/sine sweeps of all three systems in the E90? I can also do a Termlab SPL measurement as well.

It certainly would be interesting. Understanding the response of each individual driver would be especially so.

That is one test I will most likely not be able to accomplish with my equipment.

I had one of those "you big dummy" moments today.. I received my individual audio gear in today and have already swapped out the front components and center before doing any testing...

guess I will just have to do the logic 7 and hifi testing in my wife's car..
