Dazed and Confused

[Bert Friedman]

I ama really having a time getting REW to work for my setup, Save me from drinking a double Whiskey Please
I have the following setup
A 5 monitor trade station in my home theater room
A very Capable Computer with an additional Graphics Card I have the stock AMD motherboard integrated AMD and an Nvidia add on card. I have 6 monitos connected if you include the 6th which is fiber AOC HDMI out to my AVR Yamaha RX0V685
I have the Focusrite SOLO4th gen
I have the Dayton EMM6
I can not for the life of me get this working right but I get close.
I installed ASIO4All v2
Please tell me what in the world I am doing wrong or if this is too much as I was really thinking after years of that horrid Firewire Firebox I was finally going to move up to better gear and gain knowledge and process. I want to be able to test each channel in my 5.1.2 setup.

Don't use that. Use Java drivers in REW and choose the device names that start with EXCL.

Ok thank for the blazing fast response. I did what you said and I have input and output going. Now I am facing what I always faced before I never get the level to match up. Could I just have gotten a crappy mic the whole time? I used my phone Sound Meter and got up to about 63 db but it was so super loud. I just have never been able to get the input level to match of get close to the output level. What am I doing wrong?

 

[Bert Friedman]

BTW my mic is at the listening position and I tried the subwoofer and mains levels checks. I am using the L output in REW preferences.

 

[John Mulcahy]

Those levels are not meant to match, that's only for testing electronics or loopbacks. Typical mic input levels are around -60 dBFS.

I'm still learning how to interpret these. Can anyone take a look? I have 19 mic position captures from exactly measured positions. These are No SUBS then just Subs. With port foam in and not in. I think I measured in a very methodically manner. I definitely got way better captures than I ever did with that horrid Firebox. I tried using the Impulse but it showed ZERO which I did not understand. Phase is what does not look great but I need to learn more about that reading. Thank You

These are what I built and measured. They sound amazing. A lot of time and effort went into these. Multi material internal dampening. Very balanced physical load to the Woofer. LR4 Crossovers using quality components. These speakers completely changed my Theater experience. They get very loud while being very clean and the room excitation is very low I would say a calm loud room if that makes sense. I took most of the absorptive wall materials down because it was no longer needed. These are a waveguide of my own design that started from 2 other sources but I then modified it. Instead of fully loading the tweeter I backed off for a less physical loading approach that has paid off bigly. The waveguides are loaded with Morel CAT308s but I remove the 308 faceplate and mount directly to the waveguide. The woofers are SB17CRC35-8. The crossover is LR4 2 Way. The enclosures are ported and tuned to around 40hz. I literally have 1 single room mode filter set in AVR EQ. I have the subs active DSP but honestly these waveguided MTM mains do not even need a subwoofer because they hit hard and low. The whole enclosure story is a trip. Those sub enclosures are made from 195* something Jensen speaker enclosures and a 1954 piano for the baffle. I used CLD in both enclosures, The enclosures are screwed, glued, and precise in fitting. I used 5mmeva foam and appliance blanket materials for the dampening so there are many values of multi band dampening, which also paid off in a very quiet box. I wanted these Jensne boxes and this old piano donor material to make music again like it had for many many decades so now they live on making more music and joy.

I do not have as many Xovr pics but I used quality everywhere.

Firstly, don't post 19 measurements. Cull down your measurements and be specific with your question.

Secondly, we expect measurements that have the same name to look exactly the same. Here are three measurements, all named "L Mains Centered". They are all different, and if you examine the impulse response you can also see that the pattern of reflections is different, meaning that the mic has been moved. If you move the mic, tell us the reason you moved it and where you moved it to.

Third: none of your measurements have a timing reference.

Fourth: why terminate your sweep at 15kHz?

That's fair. I did make decent notes though and included any mic position changes. Maybe I can do better in the future, thanks for scolding me and giving no information about any of my data you rock Keith. Perhaps I can be more specific when I learn more about REW analysis. If the file is too much for you then just pass me by.
