TH path length opinion needed

NEO Dan · 9th February 2010, 12:42 AM

I got stuck, I don't see a correct way to calculate L34 and S3

TIA

Well we know S3 goes from the middle of the driver (rear side) to the closest reflection. Which in this single fold will be a distance. While L23 will be where it connects to L34.

Less I am wrong which I think someone will chime in.

That's interesting. IMO if it has to be based on the drivers axis this would be more like a single fold:

___

28.28v / 100w

___

Hi NEO Dan and FlipC,

This looks interesting. I like to use the four section version, and asign an average value to S4 (=S3+S5)/2 (as it cannot be determined accurately). S3 and the distance S2 to S3 can be determined accurately. From the drawing you can see how I asign S3 to S4, and S4 to S5 (approximating the center of the cone as S4 location). I feel this method gets you in the ballpark.

Regards,

Oliver,
Thanks for this, I'll update the model when the drivers come in.
