You're probably close. Since this can't be said for hot concrete or hot water from the heater I doubt it is above 115-120° F.

Buchardt A500 Measurements and Spinorama

Well you can think whatever you like. I have no reason to troll Buchardt since I'm the guy who convinced my friend to get the A500 in the first place. Their combination of technology really matched his needs. He had a high temp issue, too hot to touch, concerned about longevity, was told it was normal (at the time), I reported it here. Yes to @mads Buchardts point they were quite likely from early production. If there is an update that reduces the temperature that would be great progress-I'll overcome my reluctance to discuss these speakers at all with my friend and ask about this. The hub we can all pray for progress at the manufacturer I guess. Perhaps this is why few active speakers incorporate streaming? I dunno.
On mine, I have measured it at about a dozen spots on the plate and it varies between less than 110 to as high as 120 at the hotest point .... after running it for hours at 75-80db volume
My friend says he is still using tuning from August 2020, I *think* due to fear of bricking with update that maybe others had or I don't know what. He said something about updates being forced, you couldn't reject them. But it seems the heat (I recall the 165F now (74C)) has nothing to do with that? Where can he see the video? Because I'd like him to be totally satisfied so I can get out of the doghouse ha ha.
By the way on another note, the reason his previous speakers had no bass was a big hole from 50-130 Hz, like 10 dB deep. Your room correction seems to have filled that in, hooray! Now we just gotta get past COVID so I can HEAR the speakers...
Hi there just a simple question here:Regarding the heat of the backplates. They do get warm to the touch yes. We did extensive test after the first batch as this did have potential heat autoshutdown happen for a few customers. Here the speakers would not be able to power on for one hour. This happens at 80 degrees Celsius, where the components are certified for max 105 degrees operation. The backplate is the only place, the speakers can get rid of their heat, they are a sealed design so that backplate is the heat sink of the speakers.
But we did find a problem with the first batch due to how the dampening material was placed in the production (was around the heat sink which is just an unfortunate production error). It was a super easy fix luckily where I made an easy instruction video on how to fix this in 5 min. Doing this took the temp down from around 68-74 degrees to 50-56. The speakers do not get hotter when playing louder. Only customers that had the speakers from the first batch, experienced these higher temperatures. And we do not see a higher failure rate on the modules from back then, in comparison to now. I actually do not think many did this fix, as the speakers still worked just fine for most, only a few cases where they went into autoshutdown.
There are a ton of misinformation out there regarding or products, or just rumors or maybe simple misunderstandings I don't know, but I sometimes read stuff that are simply not true about what we say, and our products. If someone is confused or need clarification about something, for god’s sake, just ask us. We are super active and many already know that we are a company that really tries to be as transparent as possible, also about mistakes, we do not have superpowers, we still make mistakes and learn from them. Sadly, one huge disadvantage of being so transparent is that issues tend to get overblown. The A500/A700 speakers themselves are working very well, there were a few smaller software problems where they would not register a signal at low volumes over XLR (is fixed) now, and of course this with the unnecessary higher heat output. But we have a very low failure rate on the modules themselves, also some had been so unlikely that two actually failed. The god part is that they are extremely easy to exchange, and should one break out of warranty, then it's also cheap to replace as we are not interested in earning money spare parts.
Where we do see software issues, is with the Platin hub, there are still there, and even though most customers are very happy with it, and do not experience issues, we do see that too many does. It's a product that brings so many features at such as low cost, so when Platin gets everything sorted out, it's an amazing value for sure. But the Platin hubs quality and feel sadly do not match the speakers. We have been working on a more premium solution that customers can bundle with them. We do also see customers using 3. party preamp as well, there are many options out there.
Regarding the next generation plateamps module. This is on the drawing board already, but using Hypex have never been the plan, I do not know why this is a rumor? We would be using digital amps instead of Class D like you also see with Lyngdorf amps. This would most likely still be another year before these are ready, but it would of course be something that current customers can upgrade too. Should they desire to do so, then there would be a trade in program for the old modules.
Please keep in mind that I'm rarely active in here, so if you have question, just email me instead
to declare first I see your products to be attractive on performance and design perspective, yet myself is pretty settled on Genelec system and won't plan to sidegrade anytime soon. so this is more of a curiosity thing
my question is I saw a few active design such as yours and Focal Shape, used the backplate as sole heatsink without additional heat sinks protruding at the back. while this gives a nicer look to it, it feels to me that a speaker (especially a closed design) with non-metal casing would likely be better off with some sort of heat sinking to aid air flow over for cooling down components, say for my old KEF X300A it have a massive heat sink with vertical fins sticking out and it didn't really hinders my cabling efforts or obstructing it from placing close to the wall, wouldn't it be a better option to make the back plate a tiny bit larger and incorporate a lengthwise heatsink to make things a bit cooler? since it's at the back it won't affect the sleek design of any sort, yet could mostly lower the temperature 5-10 degrees Celsius in most cases

Hmm... I must say first impression of the Theoretical-Allaround is a sonic upgrade in my space. Higher clarity with a bright tilt but not quite fatiguing, somewhat tighter better integrated bass. For some reason the theoretical 2.5 sounded disjointed while this sounds more cohesive.

I bought a pair of your A500s, never regret. Had a bit of problem setting up on the first day and after that everything has been perfect. I will upgrade the Hub as soon as you get one for us to order, SC15 does not come with HDMI ARC sadly. It's really exciting to play around with your mastertunings when new versions do come out. It always felt like a new free speaker upgrade had arrived.Regarding the heat of the backplates. They do get warm to the touch yes.

Is it just me or does the new Buchardt Android app not work at all? Instantly crashes on my Galaxy S21.
EDIT: Seems not just me. You need to have Bluetooth disabled or it crashes... https://forum.buchardtaudio.com/forum/main-forum/a700/3487-android-app-crashes-upon-start

IT does not nor has it ever. Those that bought early have been waiting for more than a year
The app does work for me now after disabling BT.
I'm just not sure how useful it is, since it seems like you need to plug a microphone into your Android phone for room calibration if not using an iPhone.
It is supposed to give you access to manual EQ if you use the Platin hub.
You are right, that does work. Although I'm probably more likely to want to auto correct the bass with the room EQ. I guess it's nice to have the option to do manual EQ.
Luckily, my partner has an iPhone so I'm covered for room EQ.

So Erin used the default tuning which is what, the 150 Hz and 2800 Hz crossover?
Consider the price, the directivity is pretty well control.
If they can remove the 300-500Hz energy firing to the back that would be perfect.
If Erin can produce the directivity graph for the other DSP settings that would be awesome.

What is your reasoning for that?

Went back to trying the default tuning per Erin's guidance, having been using the new theoretical all-around. Not a fan.
In my room (~25*15*9'), 3m triangulated/no toe, theoretical has more of a punchy clarity. Part of the issue is the standard tuning sounds like it has too much energy for my space and the details are a bit diffuse, the treble tilt helps. Suggest giving it a shot if you haven't, certainly a pleasant surprise for my usage.
