sub firing direction (1 Viewer)

[Kevin Beck]

Hey folks,..I come from car audio, where small things make a very big difference more often than not. The direction a sub is faced in a car greatly effects how is sounds and performs, no question. Are there any rules as to this kind of thing with the home theater?

Thanks GRCRY,...>>>--->

Kevin, in most HT application the sub will be crossed over at around 80Hz. There are exceptions, but for the majority of people that is the way their receiver works. In any event, frequencies in that range and lower are almost non-directional. As you browse the forum you will see a lot of DIY subs that are down firing. The only consideration is to see if the driver being used is rated for horizontal mounting. There are many good sub drivers that are not rated for this orientation. As long as there is sufficient space between the driver and the floor this method works really well.

As for placing a sub in the room. That can indeed get to be a major project. Because of the interaction between the wall boundries and the sub frequencies you will end up with humps and dips in the "in-room" response. You will also see that a lot of people here use Behringer equalizers to flatten these problem frequencies. Small changes in the position of the sub in the room can have audible results. So, if I understood your question, there isn't much problem with which way your driver faces. The bigger problem is where the driver is in the room.
