DC XL 12D2 - Fun with WinISD Simulation


Recommended Posts

Here are some winISD simulations for a DC XL 12 (dual 2 ohm) subwoofer in a 1.75 cubic foot box tuned to 31hz (square port) at 2200rms at 1 meter accounting for coil inductance.

If anything, I'm posting this for the amusement of anyone who has bought or is thinking about buying a DC XL 12 as I just did.

How accurate to you think these simulations actually are (other than not accounting for cabin gain)?

Any thought provoking comments or questions?
