Post Your Frequency Response Curve!

[Final]

This is an interesting response curve, fairly flat with a slope starting at around 2.5K. What kind of speakers are these? Are you on-axis?

The speakers are Respons Grand from Respons Audio In Sweden. An old sealed box version, been with me for ages. Measurement taken from listening position on axis some 12 feet from each speaker.

Did you post this because it's got a similar roll off above 2.5K to Final's in-room measurement?

I think I heard some Respons speakers in a CD store way, way back when there used to be CD stores everywhere. I didn't get a long listen and they weren't in an ideal environment but I liked what I heard, and I loved the pyramid look. I've been wondering what those were.

I posted it because I am jealous. You can't get an in-room response on a headphone.

Sorry to be so dense, but what exactly are you jealous of?

A full range in room system.

Are you still using the Martin Logans?

 

[Gregadd]

no . I am 100% headphone. It;s a long story.

I know I’m late to the party here (I normally use REW), but will the listed app read a UMIK-1 calibration file?

 

[tony22]

For the above, anybody?

Yes, it will. You can import it directly into REW. Oops I did not read your question properly ... which app are you talking about?

 

[tony22]

Sorry, I was not clear. I do use REW with my UMIK-1, with its cal file. I was wondering if the app mentioned at the start of this thread (the Onyx Spectrum Analyzer RTA) can accept a UMIK cal file.

Oh. Well according to the description on their website, they recommend a calibrated microphone so there is probably a way to load calibration. Can't seem to find a manual for that app.

Why do you want to use that app anyway? REW is free, and it is a de facto industry standard. That app costs $20 and I can't see anything it does that REW doesn't, except run on an iPad. Not to mention you have to spend more money on dongles to connect your UMIK-1 to the iPad. And there is no manual that I could find with a Google search. If you don't own a calibrated mic and you want to use the iPad's mic then fair enough, you could make a case for buying this app. But I regard any measurement taken with an uncalibrated mic to be for fun only, certainly not something you should be using to tune your system.

Because, one of the things I can do with and IPad and a UMIK, over my much heavier and bulkier laptop and a UMIK, is walk around the listening space checking for peaks and nulls in the bass region.

Man this is a cool forum. You guys rule.

Can't believe I've never gotten involved on this site before.

I'ma load this app and do it.

Welcome to WBF, Halydean!

And thank you for the kind words!

PS: I love Magnepan 30.7s!

MiniDSP has a great setup guide for the Umik-1 and REW.

Here's the response in my 20' x 30' room. Details about the system and room are in my profile link below.

 

[Brucemck2]

At listening position with no DSP (correction filters) and no subwoofers, at 1/6th resolution as measured by Trinnov mic. (Dips from mid 100s to mid 200s are much narrower (and deeper) at higher resolutions.)
