View Full Version : Changing a MoeLester Design

04-25-2006, 12:25 AM

Okay check out that design right there. It pretty much fits exactly what I want to do, however I'm guessing I need to minus the .084 displacement for my Pioneer sub from 1.75... so that box will actually be 1.66cuft. According to the calculator - I'm going to need to add an additional .924" to the 34.625" original Port length in order to tune the box to 32hz.

Is that correct? So it would be 1.66cuft with 35.55" of port length. Also I'm not to experienced with the slot port so I'm not sure if adding that .924" will mess anything else up, like the interior volume.

Help would be appreciated - thanks.

i think thoes plans already take displacement into account.

add up both values for the volume and you get 1.88

you should be fine with the way it is. also, i doubt you'll be able to tell a 1htz difference. adding length to the slot will decrease net volume too, so you have to compensate for that if you change anything.
