When modelling my Tempest sub with AVA 250 amp, what values do I use for the tab signal source - power and series resistance? Is it 250 and 4 ohms?
Also, is the total cone travel of a Tempest 38 mm? Or 16.4 * 2 ?
One more question to verify my modelling... Okay, if using 4 Ohms for resistance and the cone travel is indeed 38mm, then a 12.7 ft^3 box tuned to 15.5 hz will hit its mechanical limits with anything over 210 watts? (Assuming the frequencies being played include 26 hz).
Is this a pretty accurate indication? Will there be any variance?
Please feel free to correct me where I am wrong here...
Thanks
