  1. Thank you guys for the recommendations and tips....

    Thank you guys for the recommendations and tips. Yes, crossover is biased...

    Thanks Grumpy! So glad to have these out of the shop ;) Even happier to be listening to them!!
  3. Finally getting these done

    Well, well over a year later I finally found some time to finish these puppies up. Just got them up and running and sound great right out of the gate.

    I need to figure the best way to test/tweek...
  4. Hahaha, you are right!!

    Hahaha, you are right!!
  5. That's what I was thinking, well, they're sending...

    That's what I was thinking, well, they're sending me ones that presumably read 8 ohms. But I guess I'm still not sure if this is correct for the crossover schematic and an 8 Ohm L-Pad (the crossover...
  6. Running into some confusion regarding the 2420...

    Running into some confusion regarding the 2420 driver. Was ordering some radian replacement 8ohm diaphragms from parts express, when received they measure 3.9 and 4 oHm respectively. I do see that...
  7. I totally get it. I've read somewhere that "close...

    I totally get it. I've read somewhere that "close counts" when it comes to cap/inductor values, but I'd do the same thing and just make it right :)
  8. Thanks for clarifying. Man, that's a bummer,...

    Thanks for clarifying. Man, that's a bummer, these networks are challenging and time consuming (and large) enough as it is!!
  9. Ok, thanks - I guess I'll run them! Thanks Odd.

    Ok, thanks - I guess I'll run them! Thanks Odd.
  10. I know, but my plate is hard plastic and,...

    I know, but my plate is hard plastic and, although I didn't try, it seemed that it'd be too difficult to get them installed correctly into the material. I figure no biggy, just have to remove woofer...
  11. I was going for the industrial look? ;) Yeah,...

    I was going for the industrial look? ;) Yeah, when drilling them I figured it may be overkill. Ah-well, if the worst mess up is having to unscrew/screw a couple extra bolts when needing to remove the...

    Cpl more pics.. Getting going on the divider network
  13. Ok, another newbie question. Anyone have a good...

    Ok, another newbie question. Anyone have a good link to good 3mOhm resistors? I picked some up locally but the leads are hair thin and I'd like something a little more robust if possible. Martin's...
  14. I don't know what you mean by "lone protection...

    I don't know what you mean by "lone protection cap in the M2," lol. I told you I don't know much ;) I take it you don't agree (with previous linked article) that using the rectifier to amp approach...
  15. Not sure that I'm sold on the diode method, if I...

    Not sure that I'm sold on the diode method, if I wanted easy, I probably wouldn't be building these in the first place - not to mention I have to get the girlfriend to let me put these in the family...
  16. Thanks, forgive my limited knowledge. Is this...

    Thanks, forgive my limited knowledge. Is this right: The "R101" is the 10 k Ohm resistor which is 1/4 watt metal/carbon in series with the diode? where does the other terminal on the diode connect,...
  17. Whoa back the truck up! I haven't heard this...

    Whoa back the truck up! I haven't heard this before. Can you explain a little more? Where does the charging come from and how would these be connected??
  18. I've read for charge coupled designs that...

    I've read for charge coupled designs that anywhere from 2-6 Mohms is OK. For the crossover below, looking at the 2421 circuit, there are 3 spots where the 3Mohm resistors will be placed. To me it...
  19. But what about the resistance change being in a...

    But what about the resistance change being in a parallel circuit (admittedly, within a crossover network I don't know how this actually would measure out). But, in true parallel the total resistance...
  20. Progress is still being made, I'll get some pics...

    Progress is still being made, I'll get some pics up shortly but coming up on a couple more questions:

    1) As far as tuning; it appears original 4344's were tuned somewhere around 30hz or so (Anyone...

    LOL, nice, that's who I ended up getting the knobs from! Thanks Grumpy & hjames. Also, Grumpy - thank you very much for the single resistor failure scenario, that is exactly what I was looking for......
  22. Thank you Odd! I couldn't find Knob replicas...

    Thank you Odd!

    I couldn't find Knob replicas searching around the internet, all I was able to find were the knobs that don't recess like old JBLs do. But, I found a guy on EBAY who makes them out...

    JBLP: Thanks man! your project has been much more than just helpful. I've found a fair bit of extra time lately, it's been fun ;) Getting excited to hearing these! I'm hoping to have them running...
  24. 4344 BUILD, and some questions for the pros :)

    Hey guys,

    Trying to get finished up on my new build and am stuck on a few items (being a bit of a newbie):

    1) Anyone know where to source some L-Pad knobs like original JBLs? And/or, does...

    Thanks again for your time Grumpy. I should have clarified more about the crossover. Yes, that is what I'm building, but, since I'm using an electronic x-over to bi-amp, all items in the dotted lines...
