Neumann KH420 Review (Studio Monitor)

And why do capacitor manufacturers tell you the life of the component in hours and not in how many times it is powered and removed from voltage?

And why do capacitor manufacturers tell you the life of the component in hours and not in how many times it is powered and removed from voltage?

Because there's no single metric that can adequately describe a complex component. By using a conservative rating in hours and designing a system within the intended operating conditions, you can expect to receive the rated lifetime or greater. That's not to say the behavior of capacitor life is actually as simple as a single rating though. This link has some nice information on the topic.

Calculating the Lifespan of Electrolytic Capacitors with De-Rating - News

Aluminum electrolytic capacitors have a reputation as having a short life expectancy and being unreliable...but are they really that much worse than other types of capacitor?

www.allaboutcircuits.com

Manufacturers of capacitors will typically provide de-rating calculations or graphs based on their research and field testing. Often times, these calculations are not included in the component datasheet but are instead found in a separate capacitor characteristics document (the reason for this is that there is probably just too much extra information to include in a datasheet).

So 2000 € difference for a pair.

Two years later…
Now the Neumanns cost €98 more per pair than the Genelecs.

And they're still not made out of aluminum

Only after you'll touch them you'll understand
You can never go back to MDF and plastic

We've been here before, but chipboard and MDF if carefully selected, can absorb cabinet resonances perhaps better than ringy metallic ones, certainly rectangular box shapes. Genelec arguably get away with it as the enclosures are cast? and curved.

I'm about to return (hopefully if they've survived storage) to a pair of thin-wall birch ply 'BeeBeeCee boxes' which 'talk' like mad on bass notes at anything over a low volume. Part of the design originally, to keep the midrange as good as possible and back then, it worked. As I can't play the likes of System 7 at anything like a spirited volume level (my ears and our neighbour that we want to remain on friendly terms with), it'll probably not matter (I live in hope)

And yes PJ, I look longingly at the Genelec 8381As which I guarantee would wipe the effin' floor and then some with almost all 'domestic' speaker confections at almost any price, but I changed direction in my life thirty years ago and the hobby side and lusting after expensive audio kit disappeared in a flash as other commitments came along L)

Genelec makes rectangular shaped monitors using MDF, even most of the 8381 is MDF as only the waveguide and a part of the front plate is made of aluminum, just like the rest of their main monitors lineup. It's actually the same in most of the Neumann monitors (minus the plastic KH80), aluminum front and MDF box.

What matters ---- the results. Metal has disadvantages.

Good thing I don't lovingly stroke my monitors quite as often as I listen to them

None of them are aluminum front, it's some kind of polycarbonate plastic they call "LRIM".

The only Neumann monitor with an aluminum front is the all-aluminum KH 120.

Why ask chatbots when you can just as quickly look at the specs?

give me a moment I'll ask the chatbot

I'm Not so sure about the looks of this setup
But I'm sure it sounds good

I wouldn't mind... Not at all!

End game by any other name

Peace.

What's sitting on the middle speaker? Looks like a soundbar
