![]() OP you choose the design axis now, either directly on tweeter or exactly halfway between the woofer and tweete are 2 good ideas. When designing active in room I start look at gated measurements (& also smoothed ungated measurements) and get a fairly accurate sense of what I have building the basics. Plus even with gating there is still plenty of resolution for the typical basic Xover region. This will leave the design top heavy /bass light. Respectfully you should be gating (I look at both gated and ungated measurements here) or you will likely not have matching SPL levels as even the room reflections are summing into the responses in different amounts - especially in the bass and lower mids. so don't.Ĭlick to expand.I really think you have build in your baffel step for the woofer 1st or the whole thing is going to be way off. You shouldn't need to change those at all. those you did for the drivers are different. go for it but remember this set of EQ solutions are for the room interaction. If measurements at the listening position need EQ for the room. Once that is done, you can move the mic to a meter distance and check driver time alignment. You overlay both the woofer and tweeter responses in REW and work out the xo frequency from that overlay. If you need to EQ the driver response for the xo work, you can see what is needed easily this way. ![]() The response of the driver itself is independent of the room this way. You match gain for each driver here as well. Shouldn't need to use a gate on the measurement or any smoothing. ![]() in this case woofer and tweeter at exactly the same. When I measure drivers for crossover work it's done. Headphones are optimally suited for analyzing tonal artifacts in a recording but completely distort distance perception." -LINKWITZĪt what distance and how are you taking the measurements? There's too much hash in the response to come up with any kind of EQ/crossover solution. "Headphones are completely unsuited for judging the spatial rendering of a stereo recording that is intended for loudspeaker playback. Money doesn't buy pleasure ever."-Alan Watts "It's enormously important to understand that there is absolutely no possibility of having any pleasure in life at all without skill. Unfortunately very few of our current genre of acoustic tests have had this kind of introspection." - Geddes It is the perceived sound quality that matters not the measured quality – unless that measurement has been scaled and correlated to subjective perception through valid psychoacoustic tests. "Blind reliance on measurements can be misleading ‐ one needs to tie those measurements back to subjective perception. The room response gives a picture of the steady state SPL, where sound generation and sound dissipation in the room have reached their equilibrium." -Linkwitz The resulting curves must not be taken as a 1:1 representation of what is heard as loudness at different frequencies. " The room response must be averaged to recognize trends in the summation of direct and reflected signals at the microphone.
