I re-draw your schematic in my circuit simulation. Please take a look if there is any error from your circuit.

April fool?
Thanks, 4313B!
That's the same curve I saw, hence the question with the LEAP file.
No wonder why many resonators/notches were added onto the filters of the network to equalize the 476Be.
How come the hi-end drop off that much? Isn't it supposed to be flat beyond 20KHz?
Here they are:

Rest in peace Zilch.
Are you talking abbout this >$650K set up?
I voted JBL Array 1400 one of the top 5 best speakers at CES 2011. The speakers along with Mark Levinson gears outperformed many set ups that cost 5-10 times more. Here are the pictures of the...

Is this a Coax driver?
Model?

I increase the slope at the low end a bit more than 1dB, and here is the new measurement. The sensitivity of the Hartsfield now drops probably to about 93-95dB. Parts used are not the best, but they...
Based on data, which Guido & 4313B measured, I built a 2-Way 640Hz Crossover with EQ network to compensated for both Low & Hi to see how the 4" Be diaphragm in a 2450SL driver & LE15B (in Hartsfield...
Woody's Hartsfield today with some minor changes:
1) New lenses
2) Replace 075s with 077s (Blue diaphragm)
3) TrueExtend Be 4" Diaphragms
4) New Extreme Slope Xovers. Xover points @ 800Hz & 8...

Here is the plot of both response & impedance of the original crossover, and the new circuit, which I removed almost 2/3 of the components used in the original circuit. Dotted line is the response of...
I have the 4520 loaded with 2226H. The low end is the best I've ever heard, but they are too big for my room.
Bo,
The current set up I have:
JBL 4250 loaded with (2) JBL 2226H
JBL 2482 driver w/ 2350 horn
Fostex supper tweeter T90 (this super tweeter can go down to 3KHz)
Crossover at 550Hz & 5.3KHz...
Thanks Bo, so I need to measure the response of each case in order to know what exactly the SPL of each config. This would be lot of work!
Let make it simpler: If I connect (2) JBL 2226H (97dB...
I'm unclear about the result of the sensitivity of a system when a driver is:
1) Loaded in a box (folded horn...) with higher (or lower) sensitivity
2) Loaded in a horn with different sensitivity...
I moded my Khorns with a set of JBL 2482/2350 & Fostex T90. Xover at 600Hz & 3.5 KHz. I had L-Pads on Mid & Hi, then replaced them & Tee-Pad using resistors. The back of my Khorns bass bins are...
Do you know how much is it for a pair ?
What are the crossover points of your system?
I guess you're making RF/Microwave isolator/circulators. Use pole piece the same size of magnet in between magnet & ferrite. Normally, circular shape is the best. W/O uniform field, electrical...
