It could also be that you've adjusted to headphone listening if it's what you do mostly. I don't understand your point about mic placement, where do you mean they are placed most times?
Yes, DSP was used. But also damping panels at first reflection points etc. Viewing the room and speakers as a system that should work together.

Ive only managed to get along with Bose noise cancelling headphones, which have all their electronics nside leaving no joy for diy. Ive tried others but theyve had awful freq response causing fatigue or uncomfortable ear contact with similar results. My Grados more or less put me off headphones for life. Ive read some folk say headphones are better than speakers so I pray daily that i never have to listen to those speakers.
Id like to knw how to design a passive XO so I can make something other than single driver full range but it looks like a real pallava with test gear and stuff i dont have. Building amplifiers is much easier, you just need a scope and a good speaker. Hmmmmm, how do I get a good speaker though? To test one id need a good amp - Im seeing a catch 22 here.

Well; back in 70'Th I believed that tubes are obsolete. Now I use them in new designs, with transistors, DSP, and even SMPS-es. ;-)
However, I use DSP after I am sure that no more mechanical improvements are justified. 🙂
Ouch! Needles in your ears! Grado headphones are the only audio purchase I have ever returned. When my Sennheisers finally got beyond repair, I bought a pair of Fostex T50RP and am quite happy. Bought them to modify, but never felt the need. Headphones seem to be very personal and the Fostex luckily match my ears. Tonal balance is just right for me. I've tested that by placing a mic in the room and listening to people talk thru the headphones. With the correct level, I can't tell the difference in tone between mic'd and live.
50 years from now would probably make active speakers quite advanced and cheap to manufacture. But Passive speaker will be also there for people who like old school hifi.
90% of people who buy high end stuff just see it in magazines like GQ and buy it, the majority not knowing what an active or passive system is- ie Sonus Faber, Focal, Devialet, Mcintosh etc. They just want a showpiece for the home and easy set up.
The other 10% are the 45 yr old audio freaks who still live with mum

How many IBT were made over the years? Never heard of anybody successfully passing one.
In that case, i'd choose the cheapest/most convenient/smallest/most powerful/most efficient amplifier...

Well before you get a little carried away, Troels is still a stubborn fool. He only uses D in the bass at the very low frequencies. He's using some tube for his mid and tweeter. It's basically a 3-way with a big woofie.
Maybe eventually they improve the electronics but dsp still not offers the quality of good electronic front ends. For high end, especially high end multiway, people with money still expect the best. For low end, it's already dsp so it's not like it's a new thing.
Well, that is very 2007 of him to use class D only for the bass but, hey, baby steps... 😉
For me the biggest problem of the active configuration is, by far, the DAC problem.
With the latest gen class D, the amplifier issue is settled but there is no cost-effective equivalent (yet) for the DAC. And that is one of the very few things i successfully passed in a IBT.
So what do you do with 4-way active speakers? 4x 2ch. DAC that will cost an arm and a leg? Cheaper DAC on the midbass/sub sections ? Multi-channels DAC ?
Sure, that's not easy.
Agreed with everything, including the "amplifier issue is settled" (I'm an NCore user), and good ADC is still a challenge too. There are still those of us who are into vinyl for the sound, and while digital domain is the obvious best choice for active XOs, a good ADC is a significant issue still.
That's not to say that a modern reasonable ADC and good digital XO won't be an upgrade over most pure analog setups, but all that extra gear, and what shortfalls the conversion may have, are a pretty big stumbling block.

I am not sure about class D amp either. Troels said in his website that although watts are cheap, good watts are NOT cheap. DSP may sound easy on paper, but difficult due to complexity and cost. I am sure you can build a good multiway dsp but will probably cost much dinero and engineer time.
Yo no quiero dsp.

Catchy phrase directly from marketing dept.
...the usual one based on the reptilian fear of ''yeah, i might be missing something''
amplifiers, cables..
