oh ok thanks for that tip. I can try that. These subs came with port blockers. Actually one of the 2 ports is already blocked, at factory. I will go back and read their instruction manual, it has something about this. However, now my understanding is that the dip in my room is due to a room...

Hello Wayne, 10-15 days have passed and I have been working on my rig in my free time. Quick question for you: In the following curve, where would you align the hard knee curve for the sub? I mean what should I set the "target level" to? Should I try to align the 80Hz point of the HD curve to...

Ummm......sorry I do not understand.....made war? Hmmm. So are you saying that I should try varying the main to sub crossover frequency in my pre-amp processor and take measurements....hoping to find a crossover frequency which results in a more flat transition? This will become a...

Here is the mdat file for the measurements you ordered :cool:

I have had an interesting observation, while I was doing the tests above: I noticed that while the polarity of the left speaker was reversed, the 80Hz sine wave tone seemed louder in my room. So I placed a sound level meter I have, set it to C weighted and slow, put it in the center of the room...

Thanks for chiming in here, John, I appreciate it. So I did the test you recommended above. Here are the results. I am not 100% sure how to interpret these graphs, so please enlighten me: 1. Question 1: Since the measured sine wave graph starts by going downwards first (starting at zero), the...

no no :-) thanks for "interfering"....actually you are not interfering, you are helping. Thanks for your tips. I will measure the fronts separately and upload the mdat file here soon.

Yeah, just found out an interesting thing. I was using the RTA to check in realtime, what is going on, what is causing the huge null. I noticed that without the subs running ( fronts in full range mode) there was little output below 80 Hz. Whereas these speakers are supposed to have good output...

Thanks for your suggestions. Here is what I measured the 2 fronts + 2 subs last night. I think I may have to lower the crossover frequency from 80 Hz to maybe 50 or 60 to get rid of the suck-out. I was thinking of having the 2 large subs take do the hard work of handling the bass and let the...

Yes, the Emotiva XMC-1 has 11 PEQ bands and delays for two subs, totally independent of each other.

ok I am reading this now :-) https://www.hometheatershack.com/threads/on-minimal-eq-target-levels-and-a-hard-knee-house-curve-long.6818/

Hello Wayne, Thanks for chiming in. This is my current rig: Nvidia Shield TV > Emotiva XMC-1 > Bryston monoblock amps> Magnepan 3.6R fronts & a CC3 center + some Polk boxes for surrounds 2 Rythmik 15" servo subs ported This rig is in a traditional colonial house's family room which is open to...

Thanks for your reply. I have tried lowering the target to almost 65 dB, but then the dip becomes even more, I mean with the automatic EQ filters REW generates. I think next I should try adding all filters manually and yes, more filters!

Hi Folks, I could use a little bit of help here. Please take a look at my subs measurements. I got way too much room gain. I want to have a smooth curve, maybe with a little rise at the low end, something like the Harman curve, but first I should be able to make it flat, correct? For the past...

I am not sure what I am doing wrong, but ever since I have installed the beta version, the right click on the legend panel is missing the option to copy the selections to the other overlay graphs. I only see these three options. I bet I am missing some step. Please advise.
