![]() I was thinking about this hoping I could get away with adjusting only the bare minimum. I will set up a new curve to stop any adjustments above there. Ideally you should avoid correcting anything above your room’s transition frequency (that’s around 200 Hz). Otherwise with the standard 125 ms left, 500 ms right windowing REW uses you will see much higher SPL in high frequencies and try to lower them with EQ resulting in lost tonality even if you manage to correct the phase shifts caused by the filters (easier said than done) and then apply psychoacoustic smoothing (this is the closest you will get to the real response in high frequencies also guarantees low Qs in the filters, don’t bother with any other).Ĭheck that Excess Group Delay graph (my actual left speaker): There usually are a couple of frequencies in the high band available for EQ’ing on the condition that you see the correct response there in the first place: Make sure you FDW (like 15 cycles) your measurements. So by around 600-1000 Hz you should be done. Up to 4 times this transition frequency, there are still room effects in the sound so EQ can be useful as long as you correct only minimum phase frequencies. Even after that you should avoid using narrow EQ filters (high Q, high gain) as they will cause pre-ringing. In that band, you must still avoid “non-minimum phase” regions. This is where you are listening to your room sound not your speakers hence should be corrected. Try to stay 2-3 db around REW’s calculated target level. You are saying you are not doing any boosting EQ so it might be that you are setting your target db level too high during EQ. I’m looking forward to getting this setup and will post my progress here. This thread and documentation have been super helpful. After I’ve created the filters in RePhase would I still need to time align the sub and the mains? What is the best way to go about that?.At this point would I then follow the guide?Ī) Would I want to set the EQ target type to Full Range?ī) Any reason not to use a house curve here? Or is it just personal preference?Ĭ) Would I want to set Match Range to say 15-15,000Hz?.Determine the crossover point: is the best way to do this to set the crossover to different points and compare measurements? I can do overlapping points in the Devialet and Magico recommends measuring the sub and speakers separately and overlapping the crossovers to sum dips.I tried the “subwoofer crawl” but that didn’t seem too helpful. I picked the location with the flattest response from 10-100Hz. ![]() Determine sub location: I took measurements using a 10-200Hz sweep with no low pass filter on the sub from the three “acceptable” locations in the room.I’m using a Devialet Expert 200 so I can individually set the low and high pass filters and add delays to the speakers.Īt a high-level is this the best method to use REW: I recently bought a KEF KC62 sub and measurement mic and would like to integrate the sub with my Magico S1 two-way speakers.
