Hi Earl (and others),

Great. That helps me a lot.
At least it confirms that my basic understanding of wiring is correct. I will implement another fixed pad.
The point is that I donīt have the L-pads and I am not...
I apologize if my words were confusing or even annoying.
I will follow your advice and put the fixed pads where LP1 / LP2 are.
By "ground" I only meant that the other end of the parallel...
I do basically know how to do this.
Was just looking for a confirmation for this specific case (where I wanted to combine the pre - resistor and L-pad setting into one serial / parallel).

Hi, Rob!
Thanks for your advice.
I am aware of the 4410a network.
It is much more complex and I would like to use my existing components.
Basically it should be a quite easy calculation...
Hi!
I am still trying to fully understand the 4410 network and to implement it without attenuators.
All I intend to do is to copy the 0 dB setting for mid and high frequency with fixed L-pads...
Thank you very much, Rob. That helps me a lot.
Now the high frequency section of the schematic is easy to copy.
Since I don't have those pads I just want to avoid having to perform trial and...
Trying to ask in a different way: What impedance (ohms) do the original l-pads of the 4410 have?
Merry Christmas everyone!
Hi Rob (and others ),
I would like to thank you for your advice and the link provided.
I will be receiving my order tomorrow with an assortment of resistors and will proceed with these fixed...
This would certainly be a good idea.
Unfortunately I do not have those l-pads...
I am fully aware of L-pad calculators, just not too confident about the actual effective sensitivity values
My crossover is somewhere in between. It has a 13.5 mfd cap for the midrange.
Everybody seems to like the 4410 sound, whereas there are different opinions about t vs t3.
I am looking for a...
Hi!
My project is to implement a 4410 network into an existing JBL L80T GI speaker.
There is only two questions left:
Do I get it right, that I can use the existing crossover layout...
Thanks for all your advice.
One last thing before I place my order:
My budget is a little low so I will limit myself to the most important components concentrating on the different crossover...
Hmmm... since I will do the crossovers anyway I am willing to try the 4410 schematic on these.
Will report how it sounds...
Thanks for the advice. Will be very careful.
Made a photo of the crossover. Do they look original? They have Bennic caps (looking like MKT-type), one is 13.5mF instead of the expected 17mF...

Hi!
Could somebody familiar with this model confirm my thoughts about the JBL L80T?
I would like to get the best out of this design.
I am aware of the T3 variant but I think I would like to ...
Sorry, I know this has been discussed many times before...
Of course those 24mF caps in parallel to woofer and mid are NP electrolytics as the schematic says.
I think I will replace those.

Hello to the Forum!
I have just recently bought a pair of 250TI's (first original version).
Serial numbers are 1972 and 1973, so most probably 25 years old.
As a first step I do not want to...
