Just received a UMIK-1, time to get started with a prelim evaluation of my theater sound!
Room is 18x25x8, theater is on one side, speakers firing along the 18' dimension making the actual theater space about 18x13 with the left side open to the rest of the room.
Gear is an underpowered F-20 sub, 300 watt plate amp on a UM-15 rated for 800W, Fusion 10 Pure for LR aimed just in front of the LP, no center, SL and SR are some small bookshelf polks all powered by an AVR for now.
No room treatments.
No gear for EQ.
Set up REW with a sound card cal and UMIK cal file from minidsp. For starters I did 4 sweeps from 15 to 20k with this unfortunate result:
The suckout at 50hz is enormous
I suspect that I need to do some nearfield sweeps of each speaker and then some sweeps of all speakers across alternate LPs.
I am a total newb to this stuff so the primary purpose of this thread is to gather advice from you guys that have done these measurements with success and know how to evaluate/correct issues.
Also, is there a way to measure the delay for each speaker using REW?
Thanks in advance for the help.
Edit: Xover to sub is at 80hz
