  1. Not a Subwoofer by iamjim · · Score: 5, Insightful

    This is some guys expierence making an ENCLOSURE. I got excited, wrapping a cone w/ wire, finding a good permenant magnet. NOPE - This is something that MANY MANY people have done. It is making a subwoofer that would be the challenge. Then again, making a proper enclosure isn't easy...

    Next time get the title of the article right!

      That's the driver. I believe he is talking about making a subwoofer, which would imply the use of the device at lower frequency ranges of human hearing.

      A driver, no matter what size it is, is not a subwoofer. Subwoofers can be made with a single 12" driver, with four 18" drivers, or even a 30" driver.

      No, he doesn't tell you how to make a driver.

      Why are we bothering to argue with a bunch of kids who have absolutely no knowledge of the physics of acoustics?

      Let these folks waste their money on the "experts" at the local auto sound shop.

  2. What is missing by divide+overflow · · Score: 5, Insightful


    This isn't even a good explanation for how to create a subwoofer enclosure. It is completely missing any information on the critical variables that describe the attributes of the low frequency driver as well as the procedure for designing the enclosure and crossover network to work with the driver to produce an optimized system. You can't just throw any old speaker into a given enclosure and expect a decent result. If you don't design the enclosure around the Thiele-Small parameters for the driver you put in it you are basically throwing the driver into a pretty box and ignoring the most important factors...how the completed system will perform.

    And I wouldn't be a good slashdotter if I didn't mention are several computer programs that help with the design of speaker systems. They are really helpful for designing a subwoofer. I used such a program to design the subwoofer in my car.

    Why, in England, is router said as root-er (the networky kind) and a router (the cutting kind) is said as, um, row-ter (where 'row' is the kind of thing you may have with your girlfriend/wife, not like the boat, which you row) - the way Americans say router (the networky kind). Who was it that came up with the idea to make written english so bloody (read: 'damn') confusing?
