    Even lazier: plop the two subs on either side/behind of the couch, who cares about the rest of the room.

    @purr1n Do I need to Y cable both sides to feed the monitor? or is the load side insignificant?

    Just one side from the sub would be good enough. In fact, you really can't do it any other way. It's possible you might not need the Y splitter. I am just surmising. I don't know the details of the 300 series sub, that is if its a dual VC driver or not.

    Controller LEFT out --> Y splitter --> "L" in and "R" in of LEFT subwoofer
    LEFT subwoofer "L" out -> LEFT JBL Monitor input

    Controller RIGHT out --> Y splitter --> "L" in and "R" in of RIGHT subwoofer
    RIGHT subwoofer "L" out -> RIGHT JBL Monitor input

    I was thinking: Bifrost 2 Left >"Y" XLR into L+R Sub input
    Sub out L+R >"Y" XLR into 305P MKII input
    I know some D amps do not like running without a load but I guess we are before the amp on these line outs.

    EDIT: I emailed Harman tech support for the final word.

    Shot in the dark, but wondering if anyone has any experience with either the Focal Electra SW 1000 Be or Focal Sopra SW 1000 Be (which appears to be identical)? They use a 13" W-cone woofer.
    Horrifically overpriced at full retail ($4,799), but as I'm considering a pair of Electra floorstanders utilizing the same W-cone material in the woofers and midrange, and I can get a single or pair of closeout Electra subs for a song, I'm curious. So far, the main qualms I have after reading the spec sheets and manual is the the lowest LPF is 50Hz (given the towers are +/- 3dB down to 35ish Hz) and the only way to change settings is via remote, which makes me a little nervous about longevity.

    Don't care so much about SPL given I'm renting and mostly listen at low volumes. More interested in sound quality and resolution, and blending with the mains. Mostly interested in Rhythmik otherwise (likely F12G paper cone), as JL is too expensive and something about REL bugs me.

    That 50hz LPF limit sounds like a problem to me. Unless you get an external crossover i don't see this going well.
    My subs have a low point 40hz on the dial but with measurements it turned out to be quite a bit higher. Integration with the mains which rolloff steeply at 60hz was not possible without an external crossover.
    Maybe one of those subs that you feed with highlvl from your amp and the passes over to the mains. But i always had concerns about transparency.
    I use a minidsp Shd Studio as crossover/dirac that's connected to two dacs that go to speakers and subs.

    I believe most of the bigger Hsu Research subs have a low pass adjustable down to 30Hz at 24dB/octave.
