Default MTM Transmission Line Design-Where To Consider Center Of Speaker

Am beginning simulations for an MTM Transmission Line design, using Martin J. King's Mathcad worksheets, of course. It might turn out to be a Daline, depends on how the simulations turn out.

For the position of the woofer, do I assume that the center between the two midwoofs is the equivalent of the centerline of a single woofer? That is to say, the results of a single woofer whose center is 10" from the top of the cabinet will be the same as for two midwoofs whose centerline is 10" from the top of the cabinet?

It would seem natural that they are, but position is very important in Tranmission Line modeling, so I thought I would check.

kelticwizard,

You have it correct!

The only other reminder is to double check to make sure you have combined the two drivers correctly to obtain the equivalent single driver. There is a short write-up on my site showing how to do this step.

Good luck,
