Can you guys help me model this driver for my sub. I want something for HT that will go low and still maintain a good balance for stereo. Here are the specs of the driver (12")from Image Dynamics. qts: 0.26 qms: 4.40 qes: 0.28 Vas: 5.827cf Fs: 19.7hz SPL: 89.9db Any suggestions on ported enclosure designs? I modeled a 2.0cf enclosure tuned to 20hz. It looks pretty good but almost seemed "too" flat. Also the f3 is a little high at 45hz freeair. (that what you guys got?) Will it have enough oomph in the 20-30hz range. I will be running around 200w to it. Any help is greatly appreciated!
