Frequency response measurements would be “colored” by (i.e. include) the response of the mic. Wouldn’t go so far as to say the measurements would be useless, but I would not apply any speaker EQ based on them. However, uncalibrated mics can be useful for acoustics measurements such ETC, impulse...

The interface has audio outputs, which will connect to an input on your home theater system=. Regards, Wayne

Not many folks using interfaces and Behringer mics anymore (although I’m one of them). Your best bet is likely to stick to the prevailing wisdom of the day for using interfaces with REW. The following is from an old post at Home Theater Shack on the topic, posted by a guy who had tried...

Let the Sony do the crossover, and disable it on the SVS sub. It’s fine to have measurements for both sub and main speakers when equalizing the subwoofer. It would be best to EQ the sub from only say, 80 Hz and below, as above that point to about 100 Hz both the sub and mains are giving the...

Yes, the headroom loss is the same either way. The way to avoid internal clipping in the equalizer is to reduce the input signal appropriately. You can make it up on the back end (sub amp gain setting). Regards, Wayne

I’ve been preaching this for decades now, but that wouldn’t give any advantage that couldn’t be accomplished by simply boosting the low end to get the 20 Hz. Either way, the sub drivers and amplifiers will need enough headroom to accomplish it...

No smoothing is best for subwoofer graphs. The advantage of having a subwoofer separate from main speakers is that the main speaker location best for imaging is typically not the best for low bass performance. It’s tough to get both from one location. I’d estimate that the subs in your mains...

Won’t know until you try, and measure with REW. I haven’t had good results with catty-corner placement like that. But every room is different. Regards, Wayne

Absolutely. Here's a Comparison graph someone posted on another Forum a number of years ago. Regards, Wayne

My apologies, I confused you with the OP. I don’t think using two different equalizers is automatically a bad thing, as long as the filters aren’t overlapping. For instance, two 1/3-octave filters, one centered at 50 Hz and the other at 55 Hz: Frequencies in between 50 and 55 Hz would be...

My apologies, I somehow it didn't register that it was analog you were looking for. Your best bet is the EMM6 Basic Plus from Cross Spectrum. https://www.cross-spectrum.com/measurement/calibrated_dayton.html Regards, Wayne

Sorry, but I don't understand what that has to do with the Antimode and / or MiniDSP that I thought you were using for the subwoofer. Regards., Wayne

Thank you for the detailed reply. Very helpful. Looking again at your graphs, the reason you don’t have sufficient “thump” is the depression between 40-75 Hz. I can’t find much on your subwoofers, but I would think any decent 18” sub should have no problem digging down to 20 Hz, if not lower...

What is the make and model of sub(s)? And how big is the room (L x W x H)? Also, location in the room, i.e. corner, middle of wall, etc. Regards, Wayne

A graph showing response of the individual subs, and one combined, would be helpful. Otherwise we're flying blind. Regards, Wayne
