Help with Unibox (1 Viewer)

[AlexKunec]

Im using unibox to compare performance between the Tempest and the Dayton DVC 15". Im having probs. with excursions.i get like 30mm ONE WAY excursion @ 30hz when powered with 250w (Going to use 250w plate amp). Im i supposed to use 125w instead because their are two voice coils?

So far im leaning toward a vented Dayton sub. Any reason why i should choose otherwise?

Alex,

What are the specs of the enclosure you are modeling? Give us the internal volume and tuning frequency if ported and see if we get the same thing. And no, you should be using 250W. One DVC 15" design I'm working on will take up to 500W before I can drive the excursion to 1mm past Xmax.
