Effects of aiming a sub's output through a tube
Ok, maybe someone can help me with this...
If I have a sub that is in a seaded enclosure matching the req's of the sub, then from the front of the sub out, there is a big pipe, lets say, the same diameter of the sub, and about 2 feet long. What would be the effects of this on the output, given the sub would cross-over to produce under 120HZ, to be generous??
Maybe the Polk installers can give some ideas... otherwise I'll just have to try it to see, maybe it'll be fun :)
