Sub placement
« on: November 29, 2005, 07:08:34 pm »

Hello,

just how important do you think it is for the sub to be exactly at the same distance (depth wise), then that of my left-right?

Should it be on the same axis? Meaning, if my triangle is 8'x8'x8', should be sub also be at 8' from the top?

FYI my sub sits on the center line, and is fully phase ajustable.

As always, thank you in advance for your replies,

Remember that all sounds travel at the same speed, so trust your instinct and try to position the subwoofer the same distance from the listener as the main speakers. The variable phase adjustment will probably cause as many problems as it fixes, so you probably want to first get it physically aligned.

My first rule of subwoofer placement is that if you choose in advance where the subwoofer goes, it's the wrong place! Every small room (below 12,000 cf) will have modal response problems in the bottom two octaves, and you will generally have to place the subwoofer to embrace the room as part of the speaker system. Experimentation and measurement will most likely be necessary.
