  Just today, I was experimenting with my sub, the phase switch, the roll over frequency, it’s position in the room, etc. I felt the lowest bass was weak compared to what I was used to hearing. Stand up bass was clean all the way down, but some songs were lacking the deepest bass I had come to enjoy. <br><br>Then I discovered that the sub was not plugged into the wall. I rewired the system last week, and accidentally unplugged the sub. 😂<br><br>So, my Martin Logans have GOOD bass by themselves, and the sub DOES add that last octave. <br><br>Color me embarrassed. Tomorrow I will follow Paul’s fine instructions on this video to set it just right.

  A lot of people do not know how to use a sub... they think of it as a boombox...and the louder it booms, the more they like it. I am a pipe organ lover and have a REL Strata in front and a Q150E in the back, so I have a near flat response from 19-23000 Hz. The subs are trimmed to come in from where the main speakers(ESS AMT1D) stop playing at about 35Hz...no booming at all. The room is 50 square meters and in my listening chair 30Hz is missing from the front setup...the Q150E fill that gap...my system sound like a live performance.

  Paul never once mentioned the crossover dial or volume dial so I wouldn&apos;t say his guide was very good.

  You feel it more than hear it! You want it more like a percussion wave! Theater set up here! 🖖

  Placement of the Subwoofer is an important action to hear the music in its quality sound.

  It&apos;s likely that the high pass filter on the Sub Box that you made a quick reference to has an output for active mains or the amp for passive mains, with a signal void of the lows that are crossed over to the sub..<br><br>The Main amps get to operate more efficiently without wasting resources on the very low frequencies already handled by a designated, high power Sub Amp and the Mains woofers are relieved of the burden of reproducing the lowest Hz by a larger, more capable designated subwoofer(s).

  Trial and error as each room is different...then raise the sub off the floor! for placement

  It was noted the questioner has a JL sub. &nbsp;If it’s a JL Fathom it comes with a microphone and a setup feature that filters out unwanted resonances in the room. &nbsp;After that’s done with this specific sub, Paul’s suggestions are right on point! &nbsp;I use this subwoofer and it is quite a performer when setup properly.
