4344mk2 cross over

[magma]

Hello,
I am a new member on your great forum.
I have a pair of 4344mk2 for some months,having had of 4350,4315 then 4333B.I assume that there is several happy owner of 4344mk2,I would therefore like if there are possible modification to be made of the cross over.
Thank you very much for your assistance.

Welcome!

Why do you want to modify the crossover?
The 4344MK2 is already charge coupled and has a great crossover.

Because I replaced always on my ancient models JBL old caps with mundorf or others will very well improvements.
I would like to keep original and better on the new type of crossover.
I would appréciate any suggestion or experience from you pros.
Again thank Guido.

You should share with Spirou38. He own a pair like you. He leaves near Grenoble.

Hi

exactly which type of mundorf caps ( and others) did you use and what was the difference in sound?

thanks

Hello magma

You might want too see how they have the capacitors set-up in Everest 2. They use a mix of electrolytic and polypropylene. You are going to go broke changing out all the caps especially in the woofers and 2123 crossover.

Hello Magma,

did you really achieve an improvement with mundorf caps?
I often use Mundorf caps myself but mainly use Intertechnik Audyn caps bypassed with 0,1uF Intertechnik Audyn KPSN caps. This gives the best sound/price ratio.

Rob is right. You might have to use electrolythics too if you want to keep the original PCB's. I'm not sure that the C1 at woofer board is an MKP.

Magma,

Hello......

Capacitors are like wine.

"Appreciation of audio is a completely subjective human experience. We should no more let numbers define audio quality than we would let chemical analysis be the arbiter of fine wines. Measurements can provide a measure of insight, but are no substitute for human judgment.." (Nelson Pass)

Yes I used Mundorf Silver/Gold and Oil in my JBL's.

With suitable complimentry equipment they are worthwhile.

Money is irrelevant in this context.

What's in the 4344Mk11 is a charge-coupled network.

Pm me if you wish to discuss further.

Whys that?? They use NPE's in the CC 4344MK2 crossover. Might want to try to learn something from how NPE's were implimented the Everest 2. They are not in all sections. Gives you a more reasonable upgrade path.

The reality is magna would be better served paying good money for a nice active crossover and biamp, then look at the rest of the network.

Hi Magma,

My 4344MKII's are bi-amped and I think it's the greatest improvement I have done.

But if you want to go further, you gan get a part from Harman Japan for filter replacement so that you could use quadri active amplification.
