I looked but cannot find the posts. I recall sometime ago reading about a modification to the crossover with a capacitor for a tweak. Does anyone have a schematic and the part number of the cap used? Thanks!

Hi audiobeer
I only have this. I think it originally was posted by Giskard.
Hope it helps
Hey...
This seems to be for what you search: Giskard commentary on N333 schematic
*****
Just noticed Widget referenced this same Thread on another. Good ol' Giskard...

The schematic is what I need but I'm looking for the mod that has been mentioned before but I can't find it. Does this schematic include it? I'm hauling my speakers to the guy JBLDOG and I use localy and was hoping to find the mod I read about some months back. Thanks!
The N333 shown above is the stock crossover. I don't remember the tweak you are talking about. What kind of tweak is it?

Well, I thought that what Giskard POSTED with the schematic might be what you are looking for, to wit:Originally posted by Audiobeer

This might be of help. The 1.0 uF, 0.16 mH, and 5 ohm circuit in the N200B provides a bump around 13 kHz. You'll want to remove that when you add the 077/2405. You can reuse the 1.0 uF and the 0.16 mH for the high pass on the 077/2405 if you want. I'd personally be inclined to start from scratch and keep the stock N200B networks you have stock. Additionally, you may want to see if the HL92/2312 horn will fit in your enclosure. You can find the increase in length of that horn in the library on this site.
But since I'm not sure what you're trying to do, I surely way off base. Maybe post what you are trying to do / change and why, and that will bring out the experts.

It was a capacitor put in line to a lot of the JBLs with the 077 Tweeter.
I think the schematc is what i will stick with. I'm taking them to him in hopes that he can take care of the L pads but thought while he had them I'd have him look into the crossovers. Thanks folks!
If I remember right the tweek was a 2440/2441 in place of the 2420. Look up the S22 System in the Library. I think it's there. Giskard is that correct??

The S22 is basically the "ultimate" L300/4333. The S22 system should fit in any L200/L300/4320/4333 box as well as the EN5 enclosure JBL made available to consumers.
I couldn't find any infos for the S22.
Anybody have?

The S22 used the alnico 136A LF and the S22-1 used the SFG ferrite 136H LF as shown above. I believe the S22-2 used the 376 (2441) in place of the 375 (2440).
