I can tell you that BMW doesn't appear to do a 'house curve' perse. The input RTA shows a really basic cross over network. They did a sub sonic filter to protect the small 8" subs and then a real shallow rolloff on top. There is no input timing, nothing that looks like cabin correction EQ, etc. Not surprising since that stuff costs money.

You hit most of the worst parts of the setup from the sound of it though.

Theruleslawyer, I agree about transition. What was your remedy for that?

Just a lot of experimenting with the crossover. Its a trade off of localization and better mid bass. I ended up going higher on the crossover than I really wanted but its easier to stretch up in range. Id rather have the speaker naturally fill a frequency range than have to boost it in eq. Boosting adds distortion.

A sub made it easier as i could play a lot more with gain on the 8” without worrying about them distorting or over extending on the low end. What i would have given for. 6” mid instead…
