    While this is true I wouldn't use this as any kind of metric to justify anything less capable. You know.... unless you have to.

    I often tell people with most speakers, the speaker will get unhappy before you but with mine, you’ll get unhappy before the speakers. My speakers are JTR 212s with compression drivers/horns. I couldn’t go back to regular (non-horn) speakers now. But the CDs have to be smooth and detailed, which so far has meant higher quality compression drivers.

    You should have seen the reaction to my room at T.H.E. Show Newport in LA with my 60” TV sitting on top of a 24” subwoofer flanked by a pair of JTR 212 HT-LPs sitting on top of a pair of JBL 15” midbasses. They were going to leave because of the TV but made the disgusted faces when seeing the 24” sub. Because physics fails when a 70 lb magnet-motor moves a 24” 1.3 lb cone. Lol! Interesting story about the doc. I’ve had plenty of similar conversations and it usually doesn’t go very far if they’re “audiophiles”. And frankly I’m not that interested in fighting those ingrained beliefs. Life is too short for those with closed minds...about any subject.

    Just to continue.. But horns are actually back in fashion - among some people. Not only for home theater, but for dedicated 2-channel. Those systems are typically diy, with large horns, often front-loaded bass horns with directivity control from around 100hz and up. Some of them are now trying SEOS horns. We also have commercial horn speakers, like Avantgarde. Still, it seems like there are two sorts of people - those who like horns, and those who do not.

    I have never been a dealer or manufacturer of audio equipment, the professional side of this is new with the company Kvålsvoll Design. But I was one of the last people to convert from vinyl, I have had speakers of very different types, though all of them have been designed and built by me. In the mid-80ies I was part working in a local audio shop, so I have quite good experience with commercially available speakers too. But back then, it was not common to find 400 liter ported cabinets loaded with 15-inch woofers with high Bl, in any shop. This was also the time when the Apogees came, and that was something that actually did sound different and on some parameters quite an improvement. If you look in the designs section on my we page, there is a short note about the planar speakers I made late 80ies, with some pictures from a newspaper article. Those could never play loud, but they had some qualities that I suspect my current design never will be able to match. Trying to explain this (about the electronics) to the typical hard-core audiophile is pointless, you will never break through. For those who are not that much emotionally connected to the tech side there is hope, if you get them in to the room to listen. Most of this is actually quite simple. If you hear a difference in a dac, but this difference disappear if you do not know what you listen to, the only logical explanation is that this experienced difference is created in your brain, and has nothing to do with sound. For rational people capable of some very simple logical reasoning, this is possible to understand. But all electronics must be good enough. This does not necessarily cost much money, and as an electronics designer this is obvious to me, the parts to make an amplifier circuit does not cost a lot of money, and there are no mysterious phenomena unknown to science, that strangely only affect audio signals. The cheap amplifier in Room2 has more power, less noise, inaudible distortion - as long as you don't push the output stage beyond limits. Sound quality improve because the noise that was audible on the audiophile preamp is now gone, and there is more power available before clipping. This goes well only because the F2 speakers have decent efficiency, they are true 8 ohm - not "8 ohm dipping down to 3 ohm - and they are placed in a small room. But adding a couple of decent output stages does not need to cost so much either, like I had to in the Moderate Cinema, because the F1s kept on killing the Marantz unsufficiently dimensioned output stages. When we get into functionality, the new cheap amp kills the old on all aspects. I have already mentioned the dsp functionality for delay and crossover to the bass system. Then we have the built-in dac - no need for a separate box, and it has hdmi input for best possible connection to the computer. and then there is the calibrated master volume. No need for this on music, some will say. I say I love it, I always know how loud I have my volume turned up, on any system, because they are all calibrated to the same level. Not to mention when you want to measure something - you always know the volume is correct and repeatable. Then we have the speakers and the room. Not so easy. But solving and leaving those other issues that proved insignificant, at least leave all our time and resources and effort available to improve and solve what matters. And they say "high-end is dying".. Yes, I certainly hope so, to be replaced by good sound instead.
