Fi Q10, Hornresp, D.A.T.S, vs. Me :)

The new box sounds great, I like it. I did hook up the ol' DATS to the box in vehicle and this is what I got:

 

 

:/ From what I understand, an impedance curve like this represents a sealed box with a leak. Looks like I'm back to the drawing board looking for more port area to realize my theoretical 3dBs by going ported.

 

I'm bummed that  my Hornresp predicted impedance curve didn't match up to my DATS measured impedance curve. Anybody got any thoughts regarding that? On a side note the modeled tuning nearly match the measured tuning.

 

I did give the new box a run on the SPL Labs LCD Bass Meter. This is what I got:

 

Not bad for a single ten under 1000watts in a trunk car, but if there is more to be had, I want it.

Because it is in a vehicle. You will always have losses that will affect Q. It's never gonna be the same.

My first suggestion was going to be to pull it out of the car and remeasure.

Is it maxed out or is there more to be had?

I did measure with the box on floor, with the woofer cone pointing up. The impedance curve was almost identical. This is what I got.

I'm curious as to why it is calculating Fo in the mid 50's

My guess is the woofer is super stiff, the spiders still need breaking in.

 

I did run the DATS on the woofer before I got in a box. This is what I got. Note this was before the sub got any use, pretty much straight out of the box.

So the Fo of the sub free air came out to be almost the same as in the box?

Yes.

 

My apologies on that last graph, the ohm scale did not match the previously posted graph.
