    Hi Guys,

    Having recently been addicted to setting up a home theatre system I decided to build myself a sub. Here is the end result. Goes very nicely mind you. All for less than $500 Aussie dollars :D

    All the inspiration was taken from this article

    If anyone is thinking about building a sub themselves, I recommend it as it is very satisfying and fairly easy. I think the last time I did wood work was in High School.:lesson:

    Looks quite nice.

    Might be worth putting up some specs in the DIY section.

    Do you have a frequency response curve for it?

    It's amazing how easy it is to build a subwoofer (with the exception of putting together the actual drive unit). Indeed a flat mate at university halls tried this with some success. Question though, how come subwoofers are generally quite expensive to buy? I would have thought that if anything cost good money to build, it would be the delicate tweeter unit.

    Although it's easy to build a subwoofer, I'm sure it's pretty hard to build a *very good* subwoofer.

    Have you braced the box? I think that's pretty important in a standard box cabinet.

    The sound quality is very good. It sounds and performs as well as a unit that cost at least double its price. I went and tested a few to compare how well it goes.

    I use it 70% Music (breakbeat, Drum n Bass) and 30% Movies. Sound quality is important to me as the boominess of bass wears off over time and quality is what you are after.


    nathan_silly - I did not brace the box as I used 18mm MDF..the cabinet dimensions(outside) are 500 high x 350 deep x 400 wide so the panels are not large enough to flex to any degree. Plus it is only a 150 WRMS amp so it wont be pumping *that* hard.

    I have posted up a few graphs.

    I see you have it near the tele, did you magnetically shield it? If so, how?

    Thanks

    No it is not magnetically sheilded as it may appear. I found out the effects of magnets on TV's pretty quick let me tell you. :eek:

    It is positioned just outside of the range that effects the telly. Amazing really the amount of clearance you need.
