Subwoofer (Sealed) Problems

[Duo]

Hey guys, I need help with this.

I made a nice sealed enclosure sub for my system (as if I need anymore bass) but anyway, I used an Alpine R type 10" sub in a 15" X 15" X 15" cube all sealed. I find it produces excellent bass, but only if you go to the other end of the room away from it. Can anybody give ideas on how to "localise" the bass a bit. You hear almost no bass at all unless you get at least 8 feet away.

Help? Anybody? Please????

What you are experiencing is the interaction between the speaker and the room. Since it is a sub, the cause is most likely standing waves.

By the other end of the room, do you mean near or against the back wall?

try moving the sub around. It will prob make the most bass facing a corner, but if it has any power on it will ratle the walls and wondows and things more this way

Well, I have the sub nearly in the middle of the room and I have to go to one of the corners for good bass. I put it on a back wall, then I have to still go to a far corner for good bass. The bass in the corner is absolutely phenomenal, good tone and lots of power, but there's almost no bass in the majority of the room.


Jared: When you say near the wall, you mean facing it right?

Well, I'll try some more stuff anyway. I suppose my listening room could be too small. How small is too small for a 15" cube???

I got up an idea that the room might be just the right size to reverse the phase near the sub and counteract its effectiveness. I'll try it in a bigger room tomorrow to see what happens.

Try this trick:

Put the sub where you sit. Then wander around until you find the best bass. Try your sub there.

Thanks, that's a good idea, I'll try it tomorrow durung daylight hours. However, I'm thinking this room is actually too small for the sub perhaps.
