Also, because your AVR combines crossover with LPF for LFE measure ch4 in REW with 120Hz crossover.

(Basically the cutoff in REW should match the LPF for LFE in AVR, assuming you measure ch4)

Yeah sorry I didn't generate the new filters - was just checking on the top right settings in the screenshot - sorry for that confusion.

Yeah I always measure channel 4 when doing sub EQ. Only measure 1, 2, or 3 for full 10-20,000Hz sweeps. Will give your settings a try tonight. I remember using them previously netting in a nice sound for me. Do you still have that house curve file by the way?

You are misunderstanding how bass management and the Low Frequency Effects (LFE) channel are implemented. I will direct you here:

"The Misunderstood 0.1 LFE Channel in 5.1 Digital Surround Sound"

and here:

What is the LFE channel? - Dolby Laboratories

The bass management XO frequency has nothing to do with the brickwall LFE filter.

No, actually his Pioneer AVR is misunderstanding that the LPF for LFE should remain at 120Hz even when the crossover isn't 120Hz.

I'm quite aware of how it should work and I have read those articles several times before.

Just cleared the PEQ to the 2 FV15HPs. I took this sweep. I think I am going to just leave it like this for a while and see how I like it. I feel like the PEQ is causing more problems in the actual sound than it's helping.

Can't turn it up too much tonight, my 2 year old is sleeping. But between the subs and the 4 tactiles I just installed, I think I just might have found my magic formula. Although I've said that many times! Will definitely need more time to try out different content at louder volumes.

I've got UMIK-1 working on MacOS fine, REW is working and seeing the MIC - so good news so far.

However, with so much info (including 759 pages here!) I'm struggling to find where I should start looking.

Can someone please point me at a quick guide to use REW so I can check my pair of subwoofers.

I want to do some basic adjustments on them and check for silly mistakes (like phasing) and confirm rough low end extension, before I go through DIRAC setup but I'm struggling to figure out what to do with so much info on such a complicated (and very capable) program!

Thanks, I've looked at that but had assumed it was out of date. It includes notes about Mac issues and other software required, but with the current version of REW on a Macbook Pro I simply plug in the USB UMIK, connect the HDMI and then select the speaker and I get the test tones without issues.

If it is current, I'm assuming I follow along from Page 60 (skipping the Windows ASIO setup etc) for basic measurements and then Pg 99 for the guidelines?

I got tired of people asking about which speaker(s) or component(s) to upgrade without having any measurements.
Not that that's going to stop any time soon, but at least the link is right there.
Once again, since I haven't seen it in a little while, THANKS, JERRY!

I missed the mac bit and have never used one. I assume that once you have it working properly, the steps are the same.

The guide was developed for Windows users. Since I am not a Mac user, I cannot develop and test procedures on a platform I don't have, therefore I rely on Mac users to document how REW works for them, and I include links in the guide.

If you think the guide is out of date, then perhaps you would document what is out of date with the MAC links for everyone's benefit?

I think the most useful link for Mac users is the one @markus767 provided.

Understood, it wasn't meant as critiscism at all.

I don't think even the guide markus767 wrote is required any longer (and there is a note in it that on 5.17 beta 11 it isn't required) - my issue is I haven't really figured out enough about REW to tell other people how to do it.

What may be worth adding to the Mac section is something along the lines of:

On macOS Sierra (12.12.5), the UMIK-1 is detected automatically and when using REW 5.18 with an HDMI connection, you can select individual target speaker outputs by name within the REW measure window (eg LFE, Left, Center) without having to make any system configuration changes or to install any other software.

Then you could add a 'goto page ???' to continue the instructions...

(and page ??? is what I'm not too sure of!)

If everything is working properly on the Mac, then you could proceed to page 60, "Taking REW Measurements".

So, I finally decided to get a boom mic stand (samson mk-10) and position the mic ideally. I should get it in 2 days.

I've attached some pics of the MLP and current 5.1 speaker setup.

Question is do I want mic tip (UMIK-1 and YPAO mics) exactly at ear level like where the flash drive is on the pillows or do I want it higher so the mic isn't thrown off by the surface of the sleep number mattress/pillows.

Also, when I get Audyssey later in the fall, where should measures 2-8 be considering the MLP is single listener only and I tend to stay on the left half of bed. Right wall is 2-3 feet from MLP.

Also, should the boom be directly behind the bed given the speaker placement angles? What are some good guidelines for keeping the boom from getting in between the speakers and mic tip?
