Thanks John. Turns out the HDMI connection I needed to make is not just from the audio/soundcard but also can also come from the video card. Several years ago ran REW with stereo cable from the headphone jack. So I assumed that taking new measurements using the recommended HDMI also needed to...

I may be missing something obvious but I can't find an external soundcard for my laptop which offers HDMI output? Both my PC and laptop have internal soundcards but no HDMI output so I would prefer to add one for my laptop since it's more portable. I assume it would still need a USB...

The graph below shows a comparison of the Front Left speaker; first set to Large and then to Small. I did the measurements with REW, using the headphone jack and a Y cable connected to AUX1 on Denon X4000 front panel, input set to Stereo. To make certain speaker the was set to Small for the...

Audyssey originally set the fronts at full range with no crossover. I haven't moved the speakers but have moved the mic to confirm Matts room modes suggestion. I just used REW to compare the front left speaker's output when set to Large and then to Small. Since the Small graph is essentially...

I think Matt's advice is spot on. After more measurements, the dip from 100-150Hz does indeed seem to come from room modes. Unfortunately that doesn't resolve the other/separate question of why REW is measuring bass below the crossover setting. This is probably an Audyssey issue rather than...

Yes, Audyssey measured the fronts as 'Large' during the initial EQ (according to the 'Results' section in Setup). But then I manually changed the speakers to 'Small' and raised the crossovers to 90Hz. My understanding is that those manual settings would prevent any bass under 90Hz from playing...

Good idea; I played sine waves at 125Hz and toggled Audyssey using the remote. The SPL meter showed no drop in volume so it seems unlikely that Audyssey is the culprit. I wonder if it might be a room mode after all... Separately, can anyone explain why the REW graph shows bass being measured...

Hi After adding bass traps and a new receiver/amp, I'm trying to measure the performance of my cinema room but the results look strange. There is a large dip between 100-150 Hz for both the Left and Right front speakers (no subs or centre). I did use REW previously and there was no big dip in...
