I have my work cut out for me as I'll be attempting to smooth out things as max spl is not the objective, I still have my KK DXD12012 in the front corner of my room and I'm about to order a mic for REW, I'm currently using a Marantz 8801 for my front end and the room is treated as well and has a great balance as is but dual subs have always been the goal. I'm hoping the reports you guys have been giving on the SQ of the XV15se are indeed true and must admit I'm excited about the prospects. Any tips are greatly appreciated !
whelp down the hatch
I assume that you plan on trying to keep using the KK along with the PSA, correct? Good thing you're willing to learn REW...you're gonna need it.
Here is my standard procedure for 2 identical
subs. The only difference with your mis-matched subs would be that you have to get them both to output the same SPL (will probably have differing gain settings).
Set the gain on both subs to the same level - around 12:00-2:00 on the gain knob is a good starting point. Set phase to "0" on both subs for now.
1. Connect sub #1
only and place it at the MLP
2. Do the sub crawl to determine the best position for sub #1
3. Place sub #1
in that position
4. Connect both subs and place sub #2
at the MLP (with sub #1
playing as well)
5. Do the sub crawl to determine the best position for sub #2
6. Place sub #2
in that position
7. Playing pink noise, adjust phase on one of the subs until you get the maximum SPL at the MLP (could be variable or a simple 0/180 switch)
8. Run Audyssey, first mic position only, and "calculate"
9. Look to see where Audyssey has set your sub trim, you want it to be around -5db to -8db ideally
10. Adjust the gain on both subs by the same amount
up or down as needed
11. Repeat 8-10 until you get the sub trim around -5db to -8db
12. Run the full Audyssey calibration
13. Bump up the sub trim from 3db to 6db to your preference
Hope this helps!
