A dcon is in the same price range. I'm just saying.. It's a solid performer.

Cast iron is pretty much cast iron.<-never uses cast iron in the house, but a ton on a fire. I use cast for 90% of my cooking. I'm not used to the copper, so it gets used less. I think the cast Sears better also. J, I recommend not buying lodge because the way they cast it leaves a rough surface. In my opinion you should hit it with a grinding wheel to smooth it out if you had one. You can buy old one for cheap. If they are a little rusty it's not a problem. It's easy to clean up.

The local papers April fools joke.

That is SG2 technology aka Super Gauss 2 that Scott was using for other applications and once that contract was done he brought it to the car audio world. Here is a link to the original thread of the SG1 introduction. http://www.soundsolutionsaudio.com/forum/topic/30951-introducing-supergauss/ Hope this helps

I wouldn't be so quick to say that no design is put into them, you have to remember Fi designs and builds these.

There's a VERY easy way to set the SSF. Start by turning it all the way down and putting in a CD with test tones on it, no music. Start with something like 40hz and turn the volume up enough to get the sub moving. Now switch the tracks down one hertz at a time. As you near tuning you should see the sub moving less and less (while getting a little louder each time) then once you see the sub start moving a little more again you're a hertz or two below tuning. At this point go back and forth on the tracks and figure out which frequency the sub moves the LEAST and that is the tuning frequency of your enclosure. Now put on a track that is 3 to 5 hertz lower than your tuning frequency and turn it up enough to really get the sub moving good but without damaging it obviously. At this point you adjust the SSF up until you see the movement of the sub go down to at least half the amount it was when you started and your SSF is set with no guessing whether it's right or not. This is the exact same procedure that Nick (from Fi) has explained to many other people. It works and works very well.

There is no science. Its his legions of dumbasses who hang on his nuts that allow this to even sell. J

Money is a powerful motivator. Then again, I am not a fan of SMD, what he represents or does. J

After all Fi design and builds SSA woofers which are the best so this sub has to be good
