    Success!

    Hi fellows,

    that first step is a success, and I'm quite proud of how I did it cleanly.
    You can check the visual result, saldy not the sound. But believe me, it's just great. By far the best speakers I owned, ever. 4311? No, thanks.

    Woah! Very nice!

    Unfortunately for the 033 and 066 they were easily damaged.

    What? A second line jumped in your message, I'm too tired.
    And in my case they did not die, they were murdered... still have not found some in decent shape for collection. And I have the parts to build the CC network but the mid coil, wich I'll reuse from OEM.
    You do have a nice nickname sir

    Hi gents and best wishes,

    I have in hands 4 LE5-9 and don't know wich to take, soundwise. I can only check DCR, and maybe that's already pointless...
    5.7R - looking mint
    5.8R - dustcap slightly touched, paper black as night: dyed for sure
    6.1R - good looking, paper slighlty rotten
    6.4R - looking mint

    I've tried to search info but that brings up millions of pages...

    Going Charge Coupled: any advice?

    Hi fellows,
    here I'm ready for charge coupling. I got the parts, ready to go. So any input is welcome.

    I may buld it on a hardboard/cork/hardboard sandwich,
    have the XO outside of the cabinet (on the back, tight, or on the back, floating...)
    have the coils nicely separated,
    rewire the inside,
    rethink the 035TIA network part (really, I'm at it, let's improve it if you guys know how to. I enjoy them lowered with L-pad anyway),
    IF that is an improvement and not just a change in sound color (in wich very probale case I will leave it untouched) add some brace or wool inside the cabinet, stiffen the LE5-9 case (tiny pipe then glued to get rigidity or bitumen damping),
    choose a nice way of connecting wires (Speakon? Phoenix?),
    and other good ideas you may have!

    Matthieu

    I am late to the party, but those 4313Ti look absolutely stunning
    The visual match of the 035 with the other drivers is much better than the original 066 IMO.

    (Speakon? Phoenix?)
    Speakon without a doubt!

    4343B Ti: sounds good!

    Welcome to the party!
    Yep aluminum outside and black inside for all drivers now, a detail but as you I've found that add a touch of design untiy
    One vote for speakon, registered.

    I'm in the caps matching process, values fine tuning with the use of polystyrene caps to bypass large polypropylene ones.

    Question Oops! Was 4313Ti

    Hi gents,

    As I have two extra resistors (went for the same but higher power rating for the mids), being R3 and R4 in the 3113B network shown below :

    * are they used as a 3dB/8Ω attenuation before the adjustable L-Pad?

    if yes,

    * can I add these resistors before the 035TiA L-pad, being something like 2/3dB louder than the long gone 066?

    That will bring back the foilcal scaling OK, allowing to play with it at its best.
    The power rating of these Mills should be Ok for HF. ( http://www.hificollective.co.uk/site...lls_data_0.pdf )

    Another questions, just for my curiosity:
    these are used in my 4406 also (where I've first planned to use these left resistors), but insterted between the input cap and the coil, will that just act as the pad or also in frequency filtering?

    Hi there,
    read that http://www.audioheritage.org/vbullet...0-Fixed-L-Pads and understood I'll need to mesure the actual Z prior to any change. I'll let the front L-Pad and if/when settings are ok for my actual room I may mesure and then replace that with resistors. So that is something to be done after CC is finished.

    Side note, I've used the Mills MRA-5, both 2.4 and 20R, in the 4406 to replace the ciement ones. I've tightened the spades and screws at terminals while at it. Highs sound finer, maybe the loose connections, maybe the Mills resistors...

    Round and round...

    Hi fellows,
    I wonder what to do with wires:
    - are they of well-sized gauge and quality to be re-used, or
    - do I need to change them (no endless catfight here, if I change it -meaning OEM are crap- it will be for twisted Teflon silver plated copper) ?

    Foam dampeners, I used a quite high density one. That should do the trick nicely. Extension wires, solid copper from Cat6 ethernet cable, 23AWG, are held with neoprene glue. Tight enough and no vibrations here.

    Casing prior to the sealing of the assy, I like the look, hope I'll like the sound as much =) But the 035TiA is in fact something like 4mm deeper in the 4313B, will this have an impact on delay? I guess a tilted speaker does have the same or even more amount of time shift?!
    Attachment 61534
    will that foam in th middle deteriorate after a while and get in the coil? does it change the sound? like fiberglass inside an enclosure?

    As for the foam it is because original one degrades that I did change it, common issue with several drivers.
    That kind of thing:
    http://ls3-5a-forum.com/phpBB3/viewt...p?f=21&t=10749
    Yes it changes the sound; undampened, the Titanium plays too loud too harsh.

    BTW, I've never heard the same as for the glass fibrer, in my speakers they look just fine, no loss of size due to gravity and vibration compression, like it can been seen under older roofs... You have example of it in speakers?
