Post Subject: Tuning By EarPosted by Lbjefferies7 on: 9/16/2008

That is certainly a new idea.  Unless it is really easy to take it out and start over, I would not do it.  I just have no idea whether or not it will work without making noise.  I have always just used mathematical calculations for ported speakers, so anything I write here should be taken at face value.  http://graph.flexunits.com:8080/index.htm may be a helpful calculator for you to play with. 

If you had one pipe with an inner diameter at 1.25" and another pipe with an outer diameter of 1.25", you could cut off the ends at a 45 degree angle.  The theoretical port length should be at the mid point of the angle.  The inner pipe could then be turned to very finely tune the port.  I hope this is clearer than it sounds.  Check out the attachment.  I think that this might be the best way to finely adjust the length of the port while minimizing the risk of unwanted noise.
