I have looked around but have not found the answer so apologies if this has been answered before (please provide link if it has). Just added McIntosh MX150 pre/pro with RoomPerfect. Want to know a simple step by step how to properly integrate two JL Audio Fathom F112 subs. L/R speakers are B&W 803 Diamonds, center is B&W HTM2, and surrounds are in wall B&W 7.3s. Amps are MC452 for fronts and MC207 for center and surrounds. The simpler the procedure the better to establish base line and from there with more input from everyone can improve later if needed. What are the correct settings for the JL Audio sub before running RoomPerfect?

What should be the variable gain setting on each sub before running RoomPerfect? (want RoomPerfect to be at or close to reference 0 instead of minus dB for the subs) Should I run ARO before or after RoomPerfect?

After running RoomPerfect what should I then set the sub settings? Should I press the defeat on the sub to bypass ARO? How do I determine phase? Badges of fury 2013 english subtitles download.

Simple way How do I determine polarity? Simple way I have a radio shack meter. Before running RoomPerfect should I set distance and level? Suggestions on running RoomPerfect focus point 1 and room measurements to get close to 100% room accuracy? Should I run additional focus points?

More questions I did not ask? I know I am asking a lot. I want to get settings right today for movie night. Originally Posted by jameslrock Thanks.

How do you have the subs connected to the pre/pro? I suggest you run them in Master/Slave mode. Are their manufacture dates the same. (or very similar)?

When I had my pair of JL F112's, the manufacture date was about a year apart and JL had made a running change to the gain structure of the amp. They were 12 dB different. I called JL and they sent me a new amp with the identical gain structure to my newer sub and all was fixed, but I only knew of the problem because I measured them. How are the subs placed in the room?

Are they equidistant to the listening position? If so, you should be able to leave the phase and polarity settings at 0. It's been a while since I had my JL's, but IIRC, when you run them Master/Slve and run ARO, it applies the filter to both subs. Check the manual, but I believe that is the case. If so, do that before running the Mac software.

For the level settings, I would use the detented 0 setting and let the Mac set the levels from there. It should do the calibration, and you shouldn't need to mess with it afterwards. I'm not familiar with the Mac, so I can't advise any further on that. You're gonna love those subs. Just be somewhat judicious with the Master Volume Control. They have great sound quality and they dig to 20 Hz, but they're not SPL monsters. Originally Posted by jameslrock Thanks.

I am mainly interested in working with integrating two JL Audio fathom f112's with RoomPerfect using the MX150. How do I work with both of the sub settings? I use an F112 in my main system along with a Velodyne SMS Digital Subwoofer Management System, the SMS allows for in room frequency response to be measured and using a calibrated microphone and to be viewed on a monitor. Using the on-board B-band digital parametricequalizer you manually adjust the settings. I didn't utilize ARO and instead left the settings to there out of the box default.
