I Was Considering Active, Then I Watched This ...

Further, so now it’s being said that you can have an "active" speaker without the amps in the box! 

The JBL M2 doesn't have the amps in the speaker. GGNTKT builds active speakers with all the DSP, amplification,  DAC in an external box. 

I wouldn't worry to much this guy has no idea what he's blabbering about. The amp doesn't "rattle" around in the speaker, dsp is upgraded all the time with software. Not all active speakers have the electronics in the speaker, Genelec has been making actives for a long time and still service 20 year old speakers,  most studios use active for a reason, they're more accurate and less trouble. 

Here’s some active speakers for the budget constrained.
Insightful ramblings not needed.

There’s active speakers at all price points from very modest excellent monitors from JBL and Adam to systems in the 6 figures.

But I thought the whole idea is that powered speakers (with DSP) are suppose to take the room (somewhat) out of the equation?

DSP with active or passive speakers will help do that if used correctly. One of the advantages of active is DSP tuned crossovers. You mentioned Buchardt, it's companies like them and Dutch and Dutch,  Kii, GGNTKT and others looking to the future not back at old guys like me is what high fidelity will be not what it was, but better. 

What speakers are you looking at high-amp?

Even with actives it's good to get the best FR , to me that's the flattest, with placement and acoustic treatment before using room correction. My room isn't that bad I've only used a few filters below 200hz on passives and actives I've had. 

High-amp  I've been reading about the Buchardt A700 you mentioned. Not a lot on it but sure looks interesting. I might order a pair they have a 45 day return policy. If I do I'll post some room measurements of them. 

When I was looking at the tunnings it mentioned do not use on the A500.

I'm not interested in what speaker was replaced or any other subjective argument. I'll look at the measurements, technology used and the science behind it. I'm not interested in a shrine of equipment amassed in a room. Those days are dying and none to soon. Adios, farewell, bye bye. 

That links the A500 the A700 are different you can't interchange them.  I've been researching them and the Genelec 8351b. The Buchardt are more consumer friendly which might influence some people, it doesn't really matter to me I'm looking for the best sounding and easiest to integrate within a certain price range. Genelec has their own room correction with the GLM add on. If I had unlimited funds and a larger room I'd look at the Kii3 with BXT. 

Do you have any measurements of these home made active speakers?

Depends on the active speaker. Newer designs are using DSP and have DACs in the speaker I don’t think the digital front end will have any difference. I had a. discussion with a salesman trying to sell me a 16K DAC as to how it would benefit me after the signal passes through the DAC in my speaker? He eventually admitted it wouldn’t.

Why are you telling me what I already know? I never mentioned "powered speakers" I was talking about active speakers with digital active crossovers. Active speakers can have digital and analog inputs and not necessarily be class d but class AB, G or H. With a properly designed active the front end components are not really much of a concern. If you want to see a properly designed modern active look at the Genelec Ones , ATC is still in the dark ages.

I was referring to this. An active speaker with DSP I'm not sure what you mean? 
I've had different active speakers using very different sources I never noticed much difference , I noticed a difference between speakers not what fed them. 

With a properly designed active the differences in the front end are far more dramatic than ever before, yielding just as much fun in experimenting with cartridges, tonearms, DACs, etc. So from my experience, active enables even greater insight into the minute details of recordings and all the associated gear
