Subwoofer question.

[Ginzoo]

I know about the equidistant monitor placement in regards to ear level. My question is about placement of the subwoofer.Should it be on the same plane as the monitors or does that matter ? Can it be under the workstation or would that affect the mixing/blending of the bass frequencies(I think so but have not built anything to try this).
In my trial runs with mixing in my new room the subwoofer(being in between the monitors cause there was'nt any other place for it) the bass is overwelming in the room but nonexistant on other systems unless I dramaticaly compensate for it .
My search for sub questions did not specify sub placement.

Thanks for any and all replys.

The frequencies produced by the sub are non-directional to the human ear - so the position of the sub doesn'y have a directional factor like the main speakers. Usually it is placed on the floor between the speakers or under the work station as you suggested. Play around with the position and find a place that suits.

Thanks John,I was planning on mounting it just up off of the floor on an absorbant/shock-resistant platform to prevent sound transmission to other parts of the house.

As always your advice is greatly appreciated.

Subs are funny, because they are so different and the power level you run them at significantly impacts how much "woof" you have. I found that mounting mine too close to my console table would result in tremendous bass, so I relocated it into a far corner of the room, next to a sofa. Using a frequency analyzer, I found that this helped level things off, but there still was too much bass while running white noise through the system.

So, I removed the sub from the in-series monitor wiring, and drive it with a seperate amplifier, so I can individually control the levels of the monitors, and the sub. This solved the problem, and required an e-bay purchased sampson servo 270 amp for about $150 more or less.

Since bass is non-directional, location is not the most important thing, though do know that the further away you put it, the more phase cancellations you may have with your higher frequencies. Adjusting the position of the woofer a few inches in any direction often clears that up. I have the woofer feet position marked on the floor with a marker, so if its bumped I can put it back somewhat accurately.

Great info frederic.Thanks.

I'm just going to have play around with the positioning.It sounds SO different in the few spots that I have tried it.
