Hey Mark (Moe), how did you get your 4430 horns so shiny? I can see from the pictures that they are super minty. Did you use Armor All? Mine are nice but not that shiny. And after I looked at the...

Hey Mark (Moe), how did you get your 4430 horns so shiny? I can see from the pictures that they are super minty. Did you use Armor All? Mine are nice but not that shiny. And after I looked at the...
About all I can add, and say, is, "you're darn tootin".
I initially powered my pair with a McIntosh MC-2105 Amp for a few months. Sure, they sounded nice. The 2105 is a nice warm rich sounding...
I finally completed the crossovers for the 4430's! I had been using the stock woofer inductors with the charge coupled configuration and new inductors for the horn. After waiting for 3...
It can be done with a current source type of amplifier like some of Nelson Pass First Watt amplifiers.
But that’s an expensive stretch.

It can be done but then one would be missing...
Hi Ian,
I actually experimented a bit with room placement, especially height for quite some time. What I found, for my particular room setup, was that the 4430's sounded their best (this was...
Emotion has something to do with it, sure, but if a speaker can evoke that type of emotion while playing music then it is doing what the designers intended. I visited a friend today who has a large...
My past experience with Solen fast cap capacitors in crossover upgrades was so-so. Mind, you, I was using them as singles and not in a charged coupled configuration. For example, I once used...
OK then, it is quite evident that there are people on this site that are way more advanced in their electrical knowledge than I will ever be. I suspect some with electrical engineering degrees. ...
Hello Dear Kay,
I would like to state that I did not have a complete cutoff of any of the two drivers in my sound reproducer. What I did say is that I noticed that the sound was muted or muffled....
I keep looking at the customer feedback link on Yoda's forum responses and realize that it is some sort of mystical heaven where I belong once I have earned the title of JBL Jedi. In the mean time,...
Kay, I have to say thank you for bringing the L-Pad's SHARPLY into focus and to my attention. While I did not perform any of the electronic surgery you prescribed, I perceived I had a problem with...
Ok Kay, I just re evaluated the the upper high frequency rheostat on my new crossover and decided that it was not working correctly. I followed the JBL network diagram as well as Ian's detailed...
Hi Kay,
I used these L-Pads from Parts Express https://www.parts-express.com/L-Pad-50W-Mono-1-Shaft-8-Ohm-260-255 I read your thread on modifying the L-Pads and not sure I understand exactly...
I finally finished the crossover using the existing 2.6 mH inductor. I am attempting to add pictures so we will see if they go through. My work is not anywhere as neat and orderly as Kay's but it...
Hey Kay,
Very impressive work. Those caps look like they sound silky smooth! Oil caps like you have are most probably the best sounding. And the layout you have is so professional and in...
Hi All,
Thank you very kindly for your suggestions and helpful hints. Some day, I would love to try to morph the 4430's to a three way with a 10" driver. But then again if I decide to go all...
I always wondered what would happen if a person took a Heil air motion transformer and connected it to the 4430 horn? Looks like the aperture originally designed for the compression driver actually...
It looks like you have been able to match the output/speed of the Heil with the mid woofer and blended it perfectly with the 18" woofer. In my mind that is what I always wanted to do, but I was...
Hey Man, that is an awesome system. From what I hear, the JBL 2251J is one of the absolute best in mid range reproduction and realism. And I have a pair of the Heil AMT's as well. Talk about sound...
Thanks, I tried that first thing and nothing. No worries, I have the plans to destroy the Death Star but now am held up for a considerable time on parts. 2.5 mH Super Q inductors expected in...
Hi Ian (Master Yoda),
My beloved tripod droid was not able to project the holographic image of the plans as when I clicked on the attachment, I just received a picture of a paperclip. Then CP3O...
Ian, thanks again for correcting me. Yes, big difference between bi wiring and bi amping. My mom always used to tell me that I wasn't the brightest bulb in the pack and not the sharpest tool in the...
Toddalin, thank you for pointing that out. I have no experience with smaller value resistors and I am chomping at the bit to get all the parts to get this project going. I was not familiar with a...
Sorry, I just have a few more questions. I ordered the inductors from parts express yesterday and I had to improvise with 18 gauge for the smallest inductor. Also, thanks for suggesting putting...
Thanks Ian! The first thing I did was replace the binding posts with bigger gold plated ones. If I remember correctly, the stock posts were trying to pass all that voltage through a tiny aluminum...
