Subwoofer Question

Moganes, here is a suggestion I got from Mapleshade Audio that did work for me. I was having just a little too much highs from a front firing sub causing the "balance" to be off a bit. I ended up turning the sub sideways, as suggested in the catalog. It worked pretty good by eliminating most of the highs from the sub. Give that a shot, seeing it would cost you nothing about placement.

The reason that a subwoofer is non-directional below a certain frequency is because eventually the actual sound wave is so long that the ear cannot differentiate it. The reason is, usually, for high frequency sound, the ears will compare the sound they recieve with respect to one another do localize the sound. With very low frequencies, the wave is actually longer than your head is wide, so the ears cannot compare one side to another because to them, the look the same. This is why you get non-localized sound.

Do understand your comments, at least I think so. However, my experience is that the waves including lowest audibles can be felt and /or heard coming from a direction. Asking the question after the event, where did the event (sound) come from and one's answer must be their best estimate and I don't know being disallowed as an answer.

The first subs I auditoned were way back in time and in Seattle at a Magnolia audio store. I went back five or so times as I am a hard sell by most standards. The designs were downfiring as many were, and some still are. Nearly impossible to detect, immediately, the direction from which these low HZ originated. The sub fregencies just were in the room. The richness of sound was very much UP a notch or two. The side-firing designs, which are the two I have (Genesis Servo's), do emit sound to my ears from a direction either directly from the drivers and reflectively off objects, as I roam continuously about the listening room. With only one sub operating, what I am hearing is originating from a general area, and only one area. The walls and floor are very significant in this room and any room, we all agree? When both subs are connected and placed one on the right and one on the left (I prefer maximum separation and have settled at fourteen feet between), the low HZ are coming from a larger area. And the room is filled with more low HZ sound. And the direction that the sound originates from becomes very difficult to ascertain. Move away from SPOT and the point of origin becomes more ascertainable, including pinpointing some reflective sound and surfaces.

I decided on side-firing for one reason. I simply wanted as much of the music (sub sound) to arrive at my ears before bouncing off of other objects, that being the floor. It would seem logical that the shorted distance and most unobstructive path to the ears, when at the SPOT, produces the least delay and a positive result. Two side-firing, and set up to face the SPOT, are the best I have ever listened to, to this day.

Thanks for all the responses. Took a while for moderator to post this, for some reason. I've been moving this sub and playing with crossover freq and gain. I finally found a good position, which is behind my left speaker. Crossover is set to ~80Hz and gain is set to 2 o’clock. So far I am very pleased with the sound. This really is a very good sub, no question about it. Still thinking about adding a second one. \\ Thanks again.
