Rec out. To be honest I would never want to use a subwoofer without S.A.P-measurement. Because you will never get a perfect integration with your speakers. Even when you buy a subwoofer with roomcorrection it only can adjust the subwoofer a little to the room. But it still does not integrate like we do with S.A.P.-measurement.
This is a totally different level of integration. I hated subwoofers for stereo use for a long time. Until I created stealth low frequency.
This is the only way to create stealth low frequency with a subwoofer.
In other sitations you easily can audition that it does not integate perfectly. This is F irritating during listening. And not relaxt!
