Vintage audio, I know many audio enthusiasts do not care much about for a sound, inoffensive and "nothing in it". I now eat humble pie. Things change when there is an adequate detail. Never deny physics, you will never win. Big drivers are capable to move a lot of air, effortlessly. They do it with such ease and produce a big sound that multiple smaller drivers never get close to. I am sorry, we are taken a ride by audio manufacturers suggesting narrow baffle with multiple smaller drivers to the task.
I learned about membrane material effect to the sound, lightweight, rigidity and damping, this matrix is complicated as they inversely correlated. Lightweight and rigidity introduce ringing that you and I would not like to hear. Overdamped hampers dynamics and detail. Slow and muddy, you and I neither like them too. There are many speaker design philosophies, measure perfect or pleasant sound have their followings, a fine line that separates both. Hence, loudspeakers are a compromised design, and they are the major influencing factor to the sound. Given the vast sonic diversity of speaker, the magnitude of the electronic and amplification sonic profile are much less varied.
Decades into this passion, I have learned and walked away with some valuable lessons. Every audio enthusiast wanted his own signature sound, to be reckoned with. This is self-actualization. This explains audio enthusiasts' senseless audio spending. Sitting outside the fence, some wiser audio enthusiasts ridicule the audio madness, but most of their system sound not spectacular.
Recording is the king maker if you agree with me. All recordings are not recorded equal. Therefore, no matter how you dislike a sound from who and who's system, there will always be some tracks their systems shine. The horn quirkiness for instance, no system can beat them on brass, similarly voices on tubes. No one system can do all things well. So, our music genre to decide what sound to build.
Kidlin's law says, if you can write your problem down clearly, the matter is half solved. Good sound is always about the acoustics a system sings in a particular room, regardless how good is your system. People mock me on my acoustics madness, I have the last laugh. No matter difficult room acoustics may be, you only have to do once. The only sacrifice is your room aesthetic. Look, you can't have a cake and not eat it, sound or aesthetic, you decide.
Room acoustics relates to in-room reverberation time, semi anechoic room is not my thing. Technocrats want sound that emits from the speaker alone, this kind of sound only attainable from headphone, the end of the story. This is anti-nature. Sound in real world situation has some degree of reflection even in a philharmonic hall. They go on to argue that the reverberations are also captured in the recording, so we do not need the real-world reverberations. This argument is valid too but listening test tells a different story. What will happen if a system sings in an anechoic room? I have been in an anechoic room, you will get crazy. The lifelessness will drive you crazy, a great fear creeps in, psychoacoustics is one field less understood by many. Just like the sun, people in countries with less sunlight suffer depression.
Back to basics whenever you in doubt. I have exercised this many times. You want, at the end, a sound that is big and immersive.
