Barry, thank you again! Fingers crossed, my formatting will hold.

Reading your response, reassures me that I made the correct decision to not mess with the diaphragm at this time. However, I'm...

Btw how do make your paragraph breaks? I respond and it when I submit my response everything gets put together into a single paragraph.

Hi Barry, I didn’t look at the other side bc because I was worried about dissembling the diaphragm and not reinstalling it correctly. I had read that the screws had to be tightened to a specific...

You were right upon close inspection, I saw that there was a small dent on the diaphragm from someone who owned this before me. I started another thread specifically about replacement diaphragms -...

Hi Barry, this is so incredibly helpful thank you!I was able to take apart the back today to replace the foam and upon inspection, saw a small dent on the diaphragm. It seems the dent did not...

There is now a chance that I may need to change out the diaphragm in addition to the dampening pad on one of my 2441. Is there wisdom in changing out the diaphragm in the other 2441's even if it is...

I have this horrible feeling this might be the case. Of course I’m hoping that it’s not but I won’t know until I open it up. Do you or anyone have a recommendation of a good substitute diaphragm -...

This is definitely a fear of mine - I will make sure to take extra care with the mounting screws. Fingers crossed I won’t lose it to the magnet. Thank you for the helpful tip!

No kidding! I found some felt boot liners -...

To my dismay I've been hearing a slight buzzing on one of my JBL 376 drivers when the music hits a certain frequency. The buzzing isn't constant and on most frequencies the sound is fine but on...

hi Richard,

yes for now the cardboard piece was just to prevent damage to the cabinet. My question is more regarding resonance/vibration to the horn and driver and if that would be recommended in...

Thank you for this - yeah I noticed that when I took the speaker off the ground it seemed to lose a bit of the Lower frequencies. Especially now that the d130 is in a c38 which is more of a...

Is there a sonic difference if I raise the 2441 drive and horn? Currently the driver/horn are sitting on top of the cabinet sounds nice.
But I wonder if the driver made a difference if it’s...

That is so good to know - I picked one up and wasn’t sure if the lack of clicks meant it was not original and wanted to check. By the way, I’m loving the 3115’s. Recently changed out the posts and...

Hi does anyone know the difference between the 5090 Lens and the HL89 Lens?
is one the professional version of the other? It seems the HL89 is a lot more expensive than the 5090.


Also with the...

Riley! Thank you so much for this!!! I just took the speaker apart for the 100th time and found that the d130 had bendable solder lug. Now it has plenty of give. Honestly the way this project has...

Dustcap has been glued back on and most of the buzzing went away however I did see that the positive lead wire from the cone to the frame of the d130 was on the tighter side. The negative lead wire...

I spoke with speaker repair and found out that unless the D130 was a d130-L which was specifically 16ohm chances are that it might not have even been a 32ohm — that JBL by design mislabeled the ohm...

Again with great information - I havent been having great luck with the 2405 and the seller from eBay keeps sending me the wrong ones…but I guess that is par for the course at ebay.
I have another...

I had read recharging the magnets would help with the sound quality. Is there a list you may have of places that are still around and able to recharge the magnets on the 2405/077 tweeters, d130 and...

thank you for this reply Widget, again so helpful.

I was thinking about your earlier post about the DCR readings having little to do with the actually sound quality of the tweeters when I test...

Hi Richard,

If the 077/2405 were to measure differently say one measures at 5.7 and the other at 6.3 but still with in the 5.7-6.7 DCR specs would that mean one is in worse condition than the...

That’s a great word of caution - thank you Riley and Widget for the heads up on this.
I haven’t received the glue yet so haven’t touched the drivers yet.
I do however have a turntable that’s...

Honestly I had no idea about this calibration - I just got home and calibrated my meter and it stabilized at a reading of .3
So the final DCR numbers with the subtracted .3 I think would bring the...

hi Riley,
yes of course - was hoping to avoid any glue getting on the aluminum cone. Just in its edges like you mentioned.
But amazing suggestion about the MEK solvent hadn’t thought of that —...
