Thanks to JM.

That fixed it John! At the Enhancements tab, there are several enhancements you can select, one of them being 'low frequency protection' or something like that. None of the enhancement were selected, but there's an overall selection 'disable all enhancements' which I selected. Now the apparent...

Thanks!

Thanks John, that's useful. I'll attack this again in the weekend when I have some time. If the WASAPI (EXCL) doesn't solve it, where should I look next? Jan

One idea a friend gave me: I am using the sine sweep test signal. Could it be that the 'dwell time' at the low frequencies is too short for the room modes to build up, while with music playing, they have that time. That would mean that the measurement will be lower than the perceived strength...

Today's mystery is tomorrows knowledge ;-) Jan

I'm not sure what the equipment brand has to do with it? Room is about 10m long, 6m wide, 4.6m heigh. Speakers are in the middle, pretty much standing free. Some damping panels on the walls. I tested with both 2nd order and 4th order xovers. Not much difference in the anomaly I mentioned. Jan

I gave my opinion on your other thread, over here. Yes that sounds similar to what I have. But it doesn't make sense, does it. If the mike measures it flat, why would it sound boomy. I'll check out John's suggestion tomorrow. Jan

When I EQ my subs (~100Hz xover to ESLs) for reasonable flat response on REW with a UMIK-2, they sound extremely boomy and much too loud. When I set the sub level to what sounds to me like a reasonable level matched to the main speakers, and I measure with RTA, the sub level is almost 15dB lower...

OK, I understand. I think I can make this work somehow. Thanks John. Jan

Ahh yes, the acoustic pressure delivered by the measurement mike is 'just' a voltage level, so I can use an oscillator to 'calibrate' that, That'll work, thanks. But I could use two channels with the Pro version and a stereo soundcard, right? One input for the actual SPL from the mike and the...

The Logger function for the SPL meter is normally used to log SPL levels, and can be calibrated in dBSpl. I have a need to log voltage levels on one channel, and SPL on a second channel* Is there a way to set the Logger Y-axis scale to Volts, and how could I calibrate that scale? Jan *I am...

He must have been connected because he got input and output. It's just that the routing is screwed up. Jan

Another thing to check is whether or not the 'link' settings are checked. But yes, post screen shots, much easier! Jan
