key add a liric opignions and other way perspective plus joke converstion and the thread is explode really fast but in definitive this is the nature of forum.

yes my dear, your right too :o:Quote:

Hi,
I am 22, an avid listener/guitar player. My tastes center mostly around 70's progressive rock. Gentle Giant, ELP, Zappa, Pink Floyd, King Crimson, etc. My 4343's have provided me with countless hours of enjoyment. I love to listen at high levels (110db +). My L-Pads are shot, and I started thinking (my mistake), what else can I do to improve my crossovers?
I am bi-amping, using 2 Phase Linear 700's.
700 Series Two - LF
700B - MF/HF/UHF
My 4343's have:
2231A's reconed with 2235H kits
2121's are stock.
2420's are stock.
2405's are stock.
I would like to build a charge coupled network using Solens, unless anybody strongly advises otherwise. I'm also going to bypass the selector switch, hard-wired permanently to external bi-amp mode.
I am fairly new at this, though my father is an electronic engineer and he will be helping me with this project. However, his expertise is more in the field of amplification and active signal processing design.
I know the first choice would be to upgrade to 4344 components. But, using the components that I already have (list above), does anyone have a schematic or any other info that would I apply to my situation?
Any help at all would be eternally appreciated.
Thank You.

Hi
I see that you use many French capacity of the mark SCR, we had here many of probleme because their value changes a lot in time.
We use now many of polycarbonate of the mark monacor with a good resultats checks

Presumably, you understand the concept from reading elsewhere here. Do one section at a time, starting with UHF and working down. Replace the L-Pads first throughout so you can hear what's happening....Quote:

I have aquired new 2421 diaphragms, but haven't installed them yet. When I open the 4343s up again, I'll install these new diaphragms, add jumpers to bypass the rotary switch, leaving them in the bi-amp mode, and I may exchange a few caps with some "high end" caps I've aquired.
I don't think I'll do much more. These sound soo nice that I'm afraid to tinker with them too much.
Since I have a Sub1500, I might add this sub, just to see if 28Hz really helps, but actually I'm very pleased with these 4343s as is!
I suspect that if you upgraded your power amps, you'd hear an overall improvement.
Keep us posted.
Tom
I agree with Tom. You will get a lot more with other amps.Quote:

Hey Guys,
Thanks for all the responses.
I'm actually quite satisfied with my amps. The 700 Series 2 is the later version with full-comp outputs. The 700B has been modified, using the outputs for the Crown VZ-5000. The power supply on the 700B is so beefy, it loves it. My father is an authorized Crown service center, and was able to acquire these for me.
Eventually (far off in the future), maybe I'll upgrade to Crown Macro Reference amps. These amps have a damping factor of 20,000 and provide EXTREMELY tight low end response. A friend of mine has a pair of 4350's powered by 3 Macro References. 1 Channel for each LF, and the third amp powers MF, HF, UHF. They sound incredible!
To Tom,
I have a parametric EQ. I find boosting 2 or 3db @ 30hz, 1 1/2 octaves wide helps quite a bit.

mmmmmm.....
That look strait forward the work project of Ian Mackensie...
My first question is: you have taken the sorrow to read this long Thread length attentively???
Then, It seems as envisaged by Masters members that the adapted circuit of
the 3145 enriched by me does not function with one 4343 stock.
Currently, I do not have time to work on my case (hihihi) but the alternate
circuits which were presented in this thread on HF seems to be a good
way of solution.
Read atentivement also the debate around the 4343 to 4344 upgrade in general forum??
That made, subject your ideas and questions with precise details and then it will be easy to include/understand with those which want to help you,what it misses to you to go from the front one.
Normallement the 4343 suportent more than 115 dB but the condenser
having dried strong risk of Shorter well before their capacity of
origin.
It may be that the oxide and the corrosion of the LPAD are also an
unstable form of resistance... Finally according to my experiment it is clear that Bi-amp Switch is finished and contributes to a bad response and an unstable resistance in the circuit.
:cheers:
BTW permaently loose hearing after 30 seconds of 115 DB listening volume...
:blink:

Hi there,
I realise '4313B' isn't posting these day's but can anyone tell me where I can get some of this Monster Cable in 16 AWG in some varied color's? Being in Australia, I order 'most of' what I need from your "land of plenty.."!
Also interested in your choice of stranded copper OR, Tinned stranded copper? Sometimes you can get the same cable 'type' in plain copper or tinned? I am thinking the "tinned" would last longer against corrosive joins - even IF soldered..??
Many Thanks to all!

Hello Steve
I would just go with locally sourced wire and be done with it. As far as platting on the wire I have used both silver and tin lead. Tin lead will probably be scarce with RHOS. You should be able to get any reasonable finish you want and using rosin cored solder as long as you clean with alcohol it will be fine. The RMA fluxes are not particularly corrosive. Stay away from aggressive active fluxes just not needed.
Rob:)
Gave the "Fluxes" away unless I am soldering up tin-plate sheet or Galvanized plate. Then wash/flush well with water!
Found a guy on the 'bay selling assorted gauges (got some 16 AWG) of plain colored and "striped" colored wire as well. Couldn't resist that one! Can't have quite the JBL color scheme they use.. but hey, will look the part!
Now that most of the Genuine "re-cones" aren't availabe any more - have people stopped building the 43xx range of speakers..??
Are 'any' of the Newer range of drivers useable? Would be a sad day the "sawdust" stops being made from building something... I'm still looking! Can't help myself! :p
Kind Regards,
DogBox [steve]
