firing subs down?

[No-Townhustla]

I here some people say that aiming your subs down results in more bass is this true? thanks

[PaulD]

not in and of itself .... if the positioning happens to put the sub in a pressure node, then yea ........ it will increase your bass output

pressure node?

[PaulD]

yes ... inside the listening enviroment, there are high and low pressure nodes. When you put a bass speaker in a high pressure node, it will play louder ..... in low pressure node, it will be anemic. This is why some bass systems have seemingly very little output - even though the size of the subs and power of the amp are more than sufficient.

For a better description, try looking up the Kuntz tube experiment (from physics).
