IB in room response graphs

[brandonnash]

Hey guys, new to the forum and already like it. A lot on here about infinite baffle and i was wondering if anyone had measured the in room frequency responce for their setup. all i see on different web sites is how good they sound and how incredibly low the extension is, but i've never seen a graph with the response. if anyone has one please upload it cause i'd like to see.

Lots of measurements if you search around a bit... here is my thread, I have preliminary measurements there. My sub is flat down to 10Hz and beyond, I measured 120db SPL as well.

Hi brandon and welcome to the Shack!

Keep in mind that all we can measure is down to 10hz, although we are hopeful that the next release of REW will have the ability to measure down to 5hz.

And the SPL meter we would use for that could not include the RS?

[Sonnie]

Well the SPL meter part would have to be the RS, but the mic most likely wouldn't work. Actually I don't know that I've even seen a mic that is calibrated to 5hz...

Really?

Okay Ben... it's been a week, don't keep us wondering on how we can use a tire pressure gauge to calibrate a mic down to 5hz.
