  • Hi everyone I have some acoustics questions

    Hey guys, I have built a small low powered subwoofer. I know a little about room gain and that usually a corner of the room provides the most room gain for lower frequencies, in any case my small subwoofer is very loud and strong in the corner of the room but in several in fact id say most areas of the room i can barely hear it. I definitely get this issue with larger subwoofer as well but nowhere near as bad. What are some things i can do with my subwoofer to help this? is it just that my subwoofer is not loud enough? is it only that it's not positioned right in the room?

    All help is much appreciated!!!
    Thanks!
    Ford.

    Those would be Null positions
    is it only that it's not positioned right in the room?
    Have you tried it?
    Room Dimensions?

      Hi Sydney! i have tried and it's not a huge improvement so far although it does get better, it is 15.5ft by 15.5ft with a little notch in the corner of the room let me draw it up real quick!

          Rooms with equal dimensions are problematic with strong Modes/Nodes.
          Have you run a room simulator and compared to what you hear?

            The only way to get uniform response throughout a problem room is with multiple subs, spaced around the room. Two are better than one, four are better than two.

              Your small, "low-powered" sub wouldn't be 3", would it?

                  daaaaaang so even if it were a 12 inch sub with serious output it would still be a big problem? let me ask you this would the problem areas still be a lot louder with a larger and louder sub? or is it just canceled out completely?

                    its a beefy 4.5 inch sub, so yeah i know it's hardly worthy of the name "sub" but its what im shooting for anyways.

                              The terms 'beefy' and '4.5 inch' are mutually exclusive, as are the terms '4.5 inch' and 'sub woofer'. I've nothing against small drivers, I use fours in my HT, twenty four of them, but in the mains and surrounds, not the subs.
