You can do an experement to demonstrate how having something in the room will change the measurement. Here a simple program I wrote that will do a left mouse click after around 15 seconds. Get the measurement window up in REW and point the arrow over the button to start the measurement and double click the file. Leave the room quickly moving away as far as you can, and wait for the measurement to occcur. Now do the same measurement again while you are at the computer. See how it is changed? You might need to look very close. This is just some practice and no need to post graphs. This should show that the measurement is sensitive to what is inside the room.What type of items in a room cause peaks and nulls ?
Bass limited. But all main speakers should be used as 'small' when it comes to bass management.1. Jamo A340 Speaker freq range 50 Hz-20 kHz would you consider this a "Full range" or "Bass limited" ?
The subs own crossover should be disabled.2. Denon 3806 AVR, if the crossover freq for the LFE is set at 80 Hz does it matter what the sub's crossover freq is set at ?
I believe this sends the LFE track to the mains. Best to send it to the sub.3. My AVR has an option for "LFE" or "LFE+MAINS" what would be the correct setting and what is the difference ?
Nulls are often created by a reflection arriving out of phase with the main signal and so causing a null. If you increase the level of the main signal with a filter, you will also increase the level of the out of phase signal. The result is that nothing changes. All you're doing is decreasing headroom. It doesn't work..4. Why don't you treat "Nulls" more aggressively with filters ?
Change the presentation to LOG from LIN as already suggested so we can better evaluate it.5. What would you do with this graph ?
Can we see the waterfall?Here is the graph I would like some advice on
