Very nice work. Is the variable part a variable resistor or something more complex?

My understanding is that a BSC is easiest approximated using a parallel combination of a resistor and inductor which is in series with the driver.

Increasing the resistor increases the ammount of BSC loss and the inductor controls the tunover frequency.

Hi navin,
You are right about BSC network.
I only use a variable resistor and a coil. In this case I add a cap (1,8 uF) in parallel with BSC to increase high frequencies level.
So I can adjust midrange according room, amp or music.
Phil.

Would you put up a the schematic with values of your BSC. I have used BSCs with my Fostex speakers.

Hi,
Schematic and calculate :
Loudspeaker Diffraction Loss and Baffle Step Compensation Circuits
In my case I have 2 mH and near 6,8 Ohms..
What is your design and drivers ?
Phil.

I may try adding the cap.

Have a look at my little experience with FE207E in MLTL (sorry in french) :
BSC ou correction de taille

I'll assume you put the cap across the inductor and the best cap for you was 2.2uf?

Here's my trapezoid boxes for the FE-126en drivers ( Blue boxes) and the FF-125wk drivers in the (Black boxes). This box design is still a work in progress after a year and will be in-till I get it right . Jeff

Interesting and nice looking, Jeff. But...what are they? Reflex? Ported? TL? Etc. etc.
