Low efficiency speaker with high power amplification..................the high dynamics experienced to be the " perceived reality " for some people is in fact like the punches of a boxer........for them that are the dynamics. Just the same with those tube amplifiers where you can switch between UL and triode mode ..........many like the triode mode on vocal and small ensemble music but their preference goes to the UL modeperceievd as more dynamic and lively ...............what they don not understand or know that they are only compensating for the lazy loudspeaker that needs a kick in the butt...... When the triode amplifier is working with high efficiency spreakers then we understand and hear that the dynamics are fully correct.......even some very good transistor amplifiers in REAL class A were subject to that criticism of being to "gentle "...............untill one couples them with a horn system or another high sensitivity speaker , than ALL falls in place....

You are right about the timbral accuracy and the energizing of the room. Here are two experiences that I had which confirm that which you are saying. I bought my Cube Audio F8 Neo Nenuphar Mini about 2 years ago. My purchasing them was influenced by Peter Breuninger's very positive review of them. About a year and a half ago, my daughter and her husband came to visit me. He is a professional bass fiddle player. I played some very well recorded tracks featuring the bass fiddle and asked him his opinion. He said that it sounded like a real bass fiddle. I said, "But wouldn't a real bass fiddle sound bigger than what we are hearing here?" He answered, "No, it would sound exactly like this. As a matter of fact, the only thing that keeps me from thinking that there is a bass fiddle here is that I am not hearing the acoustics of this room. I am hearing the acoustics of the room in which the music was recorded." That was when I was using the first version of the F8 Neo drivers. My amp was the Bakoon Amp 13R and my DAC was the Chord Dave with the Chord Upscaler. Now I am using the F8 Neo Version 2 drivers, the Enleum Amp 23R and the Holo May Level 3 Kitsune DAC (still using the Chord Upscaler). A neighbor of mine is a music professor. His instrument is the piano and he performs in concerts. I had been asking him to come and hear my system for a long time but he was avoiding it. Finally he told me that he was reluctant to come because the piano is very difficult to record well and he was afraid that I might be offended if he found my system to be lacking. I assured him that I wanted his honest opinion and that I would not be offended in any way. I would learn from it. So finally he came. I played well recorded music featuring the piano. He was VERY surprised and impressed with the sound that he heard. He sat there listening to track after track with a big smile on his face. He said that the timbres were perfect and that he heard things that he only heard when he was playing the piano. He explained to us what the pianists were doing with the pedals. I also played other music for him... from intimate ensembles to large scale works and at one point he said, "When you go to concerts you must be a little disappointed with what you hear." And that opened up a discussion about room acoustics. He loved everything he heard and at the end was reluctant to leave. Can there be better testimony as to the quality of reproduction than that of actual musicians?

I've never thought that bass extension could rape or violet someone ;-} . Great , unique KZfaq channel , no BS , direct . I'm a big fan of SET amp ( 71A ) & single driver speakers. .

Hi, Very interesting video, I was looking at the speakers a few months ago before I replace mine they do sound amazing. Phil from the moulin France

The first time I read about the “Holodeck” analogy is in Lynn Olson’s website..

Hi Janos. Even though I would LOVE a couple of Cube Audio drivers, they are somewhat too expensive for me, so I've been looking at alternatives for my future VP build (your measurements). Is there any specific parameter of the FR driver than one has to pay special attention to, when choosing a driver for a VP? As an example, I've been thinking about using the 8" Alnico driver (SFR-200A) from Sonido. It has about the same VAS and BL, lower impedance, higher sensitivity, but X-mas is only 1.8 mm?? Any guidance would be much appreciated :) Thanks as always for your channel! Claus

No way around the microphone ! that’s just a fact and accurate low frequency is reserved for the ultra expensive studio mic.. Please do an episode on this topic and present some of the different microphones and tecnics used in recordings. High efficiency bass/sub is hard/expensive and the size just blows up like crazy. My horn sub-system is app 104 db efficient and still has to use the corners/room to get there. Most audiophiles hearing my system for the first time are usually a little disappointed cause you can’t actually hear high quality (low distortion) bass. The typical 10 kW long excursion compact woofers have very high distortion and a sound character that most listers associate with, let’s call I sub-bass…

Which is better ? 8 inch or 10 inch ? Cube audio....

Would it not be common sense to use a binaural head as microphone for exactly this purpose, to give an impression of a System in some room via YT, where 90% of the viewers use headphones?

Janos, What is your roomsize and ceiling height?
