  1. I did notice the QMS on the H was wildly...

    I did notice the QMS on the H was wildly different, yet the QTS on both drivers is very close. Isn't the QTS a function of the QMS and QES??? Doesn't make sense but I don't have a really good...

    I took the 2202s to friend who has a DATS software to measure the drivers. Are these two drivers close enough for use? Please note the T/S specs are on the right

    As mentioned both are 2202A frames...

    I have some of the Moyen cement. I have a few recone kits stashed away and they weren't purchased that long ago. The glue should be good.

    Should I apply a cloth backer to the rear of the surround...

    Lanselites

    I just noticed a tiny hole in the surround of my 2202 driver. Can you patch this in a way that will not degrade performance a possibility? Or am I looking at a recone or replacement...

    I received my 2202a drivers today.

    They both have original JBL cone kit but one is labelled 2202a and the other is 2202h. Do you think there would be a difference in the two drivers? They are both...

    At 15lbs do you think the 2311+2450 combo is too heavy to swing off the baffle without a brace?

    So the 2450SL diaphragms are out of the pickings. I just remembered they are 8 ohms and I would rather not tweak the crossover to suit them.

    If you had to choose between used 2441 diaphragms which...

    Just a quick question, if I were to use the Radian or 2450SL diaphragms in the compression driver would I need to tweak the 4355 network?

    Got the boxes. That is also 6x 2235H brand new in the box.

    I have everything besides the 2450 compression drivers. I stupidly bought the 2450SL only to find out they are a 1.5" exit.

    Definitely beyond my understanding but I trust your knowledge. I don't have the ability to design a passive network, it was more of a "I wish" statement. I hated biamping my factory 4350's, it...

    How? I am sure a modern 400 watt Krell could drive the 4350 to it's potential without the need to biamp.
  12. If I was handy and technically apt I would...

    If I was handy and technically apt I would certainly explore something like this. Sadly I'm not so I will keep it all original trying not to reinvent the wheel.

    My biggest gripe with the 4350's is...

    Will rotating the cabinet 90 degrees and vertically aligning the mid-bass/cd/tweeter make things worse, better or the same?
  14. Would using the Selenium HL14-50N horn instead of...

    Would using the Selenium HL14-50N horn instead of the 2311 be considered an improvement? If I were to use it would it require any crossover changes?
  15. I don't quite understand? Are you saying the comb...

    I don't quite understand? Are you saying the comb filtering is inherent to the 4355 design, or will be caused by mounting the drivers in a vertical line above the 2202 with the cabinets rotated 90...
  16. Thanks mate, I just figured if I were going to...

    Thanks mate, I just figured if I were going to drill new mounting holes for the drivers I might vertically align them when the cabinets are rotated.
  17. To keep this simple I think I will keep the...

    To keep this simple I think I will keep the speakers as close to original as possible. If I source a pair of 2450 with the 2" exit and install 2441 diaphragms, will I need to make any changes to the...
  18. If I got a 2445/2446 and put a 16 ohm SL...

    If I got a 2445/2446 and put a 16 ohm SL diaphragm in it, would I need to change the original 4355 crossover to accommodate for it?
  19. Is this a crazy idea? Flipping the speakers 90...

    Is this a crazy idea? Flipping the speakers 90 degrees and using the other side to mount the 2332?

    The biggest issue I had with the 4350's was them being too close together so rotating them would...
  20. Will the SL diaphragms fit in them?

    Will the SL diaphragms fit in them?
  21. Pieceing together a JBL 4350 build in Australia

    Hi All

    After selling my Factory 4350A's about a year ago I ended up purchasing an empty pair of 4350 clone cabinets at an auction. Also purchased at the auction were 3x pairs of 2235H's, 1x pair...

    If the original parts can't be improved upon maybe it's not worth changing anything.

    If you had to hinge a bet would you say the rebuilt network remaining CC'd, using high quality parts would be superior to the original? This is assuming the DCR and ESR of all the components are...

    Thanks for the link, I hadn't seen that write up.

    Interesting thought, I would never have considered ditching the CC'd networks but the reduction in capacitor values would allow for more premium...

    I know what you mean. Aware of DCR matching in regards to the inductors and series resistors are added to make up whatever difference there may be. As with changing electro's, ESR is noted.
