Room response included in Xover design?

[Zuhl]

Making a speaker "flat" inside a room will not give a good result, it just sounds way to bright.

No it doesn't! I know what me ears are telling me!

@Eriksquires: what you describe does unfortunately not say much about measurements. In your description this looks like the typical 1 meter on-tweeter-axis measurement.

Firstly, there are problems with measuring the lower midrange frequencies, as amply demonstatred by Mbrennwa in the Monkey Coffin thread: you can only properly measure nearfield until approx 300-400 Hz; your 1 metre measurement will only be valid as of approx 900 Hz in the best of cases. How to accurately find the missing 300-900 Hz range, a fair bit of which is causing our problems (or is even designed -as a dip- into the x/o?)
Furthermore, I looked at your in-room-measurements. To be honest : flat to 20-25 Hz looks to good to be true. Maybe I am wrong, but it looks more like a beautiful just one point in space coincidence than a valid measurement that holds over some area. Please do not take this is criticism, but the excursion required at 20 Hz is simply way beyond what a 6.5 midwoofer can move in terms of air. Of course there is room gain etc, but ruler flat until 20Hz...

Then your ears don't match the ears of the vast majority of human kind.

This is just another reason to go the DSP/active crossover route. You can optimize the speaker response any time you move the speakers.

Done.

Forum Moderators,
Could typing error in post title be corrected? It should read “Room response included in Xover design?”

Thanks,
