Buchardt E50

[thewas]

The measurement you see here is a rather easy and simple 4. order

If someone can call a passive 4th order easy and simple.

In the end of course compromises must be done on the on-axis tuning when the directivities don't match greatly, looking forward to the Erin spin to compare it to the one you posted.

"We could make it textbook perfect and here is proof, but decided we won't" it's an interesting take. Get the popcorns ready, looking forward to the final spins!

Hehe yeah Well no, it could not be perfect due to the design of the cabinet design, so making it look like it does, is already a small compromise. This data shown here was the best looking measurements of all the crossover designs we did, but was not what we ended up with

It'll be interesting to see what their take on the sound is/why etc

Like I said, the one posted here is NOT the one we released for the E50 So no it would look way different 4th order is of course a lot of parts, but what I mean with it, is that its a type you just see very often used. The one we ended up with where 1th / 3th order

Yes, don't worry, I also understood it like that.
By the way it is better to write "electrical order" as this avoids the often happening misunderstandings with total acoustic order.

 

[Penelinfi]

Any compensation for the little midrange peak on the Purifi?

Interesting @Mads Buchardt
Will you explain to us what attributes of the coloured sound of the E50 will make it more commercially successful in your opinion?

What I read in your previous post is that the design as a whole is quite compromised and that you have decided to offset this by embracing certain colourations. Is that a fair assessment?

Delving a little more into the “coloured” sound, how is the directivity? In my opinion if directivity is good then a house curve that is non-flat is fine.

My concern (and would love to be wrong here) is that a 1st order electrical filter won’t attenuate the high frequency output of the Purify woofer enough to avoid a directivity mismatch with the tweeter.

Do you think that high-end audio needs to be coloured to give that “musical” sound that audiophiles crave? Do you think that accurate sounding speakers sound boring?

I love the S400mk2. Did you not want the E50 to be more of the same, but with improved headroom and lower distortion, the beautiful cabinets being a large part of the product’s appeal?

I’m a big fan of what Buchardt is doing and appreciate any feedback you give.

but if you decide your equipment from an objective standpoint (which makes sense to do), then you would want the active version of this that we would make as well.

Hi All! happy to see that there are some discussion about our new E50 speakers in here. Regarding the talk about the stained black might be veneer since it does not have the finger joints? It's still solid wood, all of them are and will be for future finishes as well. If you do not like the finger joints, we can just make a pair for you without them, we build them in our own production, so we do have a ton of flexibility here

Regarding measurements of them, this is where I would have to disappoint properly all on ASR. We would have a pair shipped to Erin for testing soon, but we have with this speaker let the subjective judgment win over the objective. This is very different from many of our other designs, but if you decide your equipment from an objective standpoint (which makes sense to do), then you would want the active version of this that we would make as well. If we get so much hate for taking a different approach with this design, we can always release the first crossover we made for is which I would attached measurement of here so you can see we are not completely incompetent in doing designs There are a ton of reasons why we went in a another direction with this design, which we would release a larger paper on later. The measurement you see here is a rather easy and simple 4. order. Although it's not perfect by any means, it's the best we could do with the given design which also had to look nice, we also had designs with oval waveguides to get drivers closer, but we did not take that far as it looked ugly to me. We ended up with a design that used 1. order on the Purifi and 3. order on the SS tweeter should you be interested.

this does not mean that all passive future products from us would measure like crap now, we would in our cheaper series still develop with objective data driven designs, while still having something that looks good.

Sorry to disappoint ASR on this one, but I hope that some of you would get to listen to them one day anyways, they do sound rather fantastic despite being a little colored
Take care.

Very interesting stuff, thanks for sharing! I’d be interested in knowing the reason for taking a slightly different design direction when developing this speaker as well. Was it that in A/B tests the „worse“ measuring crossover was preferred?

 

[Matias]

Nice video!

 

[digitalfrost]

Wow. This seems like the perfect speaker for me. I don't like how the Purifi woofer looks, but man this is nice.

 

[Claudatious]

If your anything like me, you’ll be grateful for a new threat about the forthcoming E50’s from Buchardt.

I don’t know when we’ll start seeing reviews but the anticipation! I know, I know, reviews are subjective and only listening to them will give me the answer, but until I can work out how I’m going to muster the P together, reviews will be fun to read.

I recently listened to the KEF R3’s and I must say the openness and sense of space at the top end are really something. I do know what people mean when they say that they sound metallic, and I wonder if this would get tiring with prolonged listening.

I just acquired a Krell KAV-500i and on paper at least, it could be a superb match for the E50’s with the amps slight tendency to be on the open side at the top end, which may work beautifully with the E50’s.

Now, let talk colours. Natural oak speaker with raw oak stand or with black stand.

Oh man, the suspense is killing me

Not really grateful for a new thread as there already is one.

Buchardt E50

Just announced the E50 speakers from Buchardt Audio: "pre-order campaign will be announced, with an exclusive price of €3,950 /pair." https://buchardtaudio.com/pages/e50-coming-soon Made from solid wood with the tweeter waveguide carved into it. Purifi woofer but apparently PRs from another...

[Claudatious]

Someone mentioned that there are a view reviews around but I can’t see any! Does anyone know of any or have any idea as to when they can be expected.

Mads, I really liked your account of how they sounded and am drawn to them because of your description. That said it’s also interesting to hear from others.

 

[Dandan__]

I find it interesting that despite the months-long hype surrounding the E50 and the fact that two prominent YouTubers already have units in hand, we still haven't seen any reviews published. It's also notable that Buchardt hasn't released their own measurements yet. I can only assume they're waiting to amass enough sales and subjective customer reviews before releasing the objective, measurement-based ones, especially given Mads' much appreciated explanation about the compromises taken.

 

[Claudatious]

Yes, well I guess maybe the wait will make for more rigorous reviews.

About the ‘compromises’. I didn’t hear it that way. If we all wanted a speaker that was sonically neutral we’d all have Asc’s. I’m excited about the character of the E50.

That’s how I read it

 

[Claudatious]

Please say more, what is it about he cabinet that is compromising. I’d like to grasp this.

 

[kharan]

Please say more, what is it about he cabinet that is compromising. I’d like to grasp this.

I presume somewhere along the lines of size, aetherics and proportions.

Maybe there could have been larger roundovers and that would improve diffraction but it doesn't fit the aesthetics. Something about the spacing of the drivers and the crossover frequency, maybe close would have been better, but they wanted a symmetry between the top and the bottom of the speaker. Maybe the waveguide could have been a different shape. Maybe bigger passive radiators would have improved bass distortion, but they are limited by the size of the cabinet...

Maybe none of that actually matters as far as audibility goes, or maybe some of it does, or maybe all of it does, but this feels like a speaker that was designed both for acoustics and aesthetics, and the balancing act means there are compromises on both sides.
