But here's an example of why I recommend being careful when you crank it up the first time: My ported box is measured and proven at 26Hz tuning. Half octave would be 19.5Hz. Around 20.5Hz, I have a sharp impedance peak and the subs tend to bottom out around 19Hz. I was forced to set my SSF at 21Hz to avoid bottoming out. When I upgrade from 6000W to 9000W, I may have to move it up to 22-23Hz, depending on how much the subs flex. Anyway, good luck man. Use that DMM so at least you know where its set at. That makes sense. Overpowering would make all frequencies more pronounced so it would be safer to compensate by going a few hz higher on the ssf. Regarding the ssf, i got some bad advice from creacendo tech support. I told them i was tuned around 40hz and they told me to set the ssf just a tad above 3 oclock. That position woukdbbe around. 22Hz. I asked them isnt that too low and yhey said my sub can handle it since it has a strong motor. But trust me..it didnt. I found that oit the shocking and hard way. Good thing i didnt cause any damage to the sub. Just now i set the ssf as someone mentioned a lil higher than what i suspect to be 30hz and it does in fact sound cleaner and i get more nose and lip vibration now i guess cuz of less distortion and a cleaner output? I also came across an article by mtx stating the higher and closer to tuning u set your ssf the higher dbs you will do and higher point u can set your gain at as well.

It does make sense, since the cutoff frequency is 0.707 times full voltage. This means a couple of hertz above the cutoff is where the attenuation actually begins.

Some drivers are made, where they all but cant hit the back plate. Ran my sp4's in a flat, and couldnt get them to bottom out. Its the way they are built. Youd have to loose the surround, and every spider on it to go back enough to hit. Fold the surrounds and not care ftmfcsw, 4 year old drivers. When i put a 6500 on each, and my enclosure being to large, way to large, i lost rear spider joints,.... the one above my head was the worse. I ran em like that for another full season, and half the next one SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
