    Default Front Firing vs. Down Firing Subs

    I like to know what are advantages and disadvantages of having either type of sub.

    I think Front-Firing is all-around sub both for music and movies. Whereas, down-firing is mainly for movies. Or am I wrong?

    I use Velodyne CHT-15 which is a front-firing sub and works awesome for me both for movies and music. I know there are more front-firing subs especially the high-end ones but there aren't so many down-firing subs available. Why is that! I know SVS makes great DF subs but what other brands.

    Need your opinions!

    Bass waves are omni-directional and not easily absorbed. There is no difference in sound between downward, side, upward, backward, or forward firing - all other things being equal.

    The SVS cylinder fires downward, whereas the HSU cylinder fires upward. The SVS has a much lower center of gravity and is less prone to tip over, but there is no inherent sonic advantage to either design.

    Most DIY cylinders are also downward firing. If you are thinking DIY, the woofer needs to be rated/approved for downfiring because the weight of the cone over time can otherwise cause suspension sag.
