That could get close and may work. Just have to try it. I didn’t use it when I set up my 2 subs. Subs weigh too much.
What is not clear to me is what the original poster’s system is. Are we dealing with stereo bass or summed mono bass? If it is summed mono bass what equipment are they using? With stereo subs they should be near the mains for best blending in with the mains. This is often the worst place in the to put them to get even bass in the room. Opposite corners or opposite side walls are better for more even bass throughout the room with mono bass. I have 2 Rythmik F15HPs running off my AVR sub output. One is in the front of the room between the TV and the right speaker. The other is in the back of the room a couple of feet from the corner. The bass appears evenly distributed to me. Someday I will get around to measuring the response for use with my 2 channel system which will have DSP controlled subs.
You’re right, I never did put system details. I must have spaced it.
The system is 2 channel stereo
Mains: Klipsch Heresy IV
Subs: Rythmik L12 running stereo via RCA from the preamp. But I can run summed, whatever works best.
Power amp: Odyssey Khartago Stereo
Preamp: Quicksilver Audio Linestage Preamp (4 outputs)
In regards to the suggestion about aiming the subs I did find a forum post about perpendicular aiming of subs relative to the listening position and am playing with that while both subs are on the front wall. When I had 1 sub behind d the listening position I tried aiming it straight at the wall and it didn’t measure any different but it was also very near field so I’ll try that too from the front wall.
Also i went and dropped the crossover to 40hz and did a little listening, mostly Mingus, but today I’ll run the gamut (Napalm Death, Trepaneringsritualen, King Tubby, PJ Harvey, etc).
