After getting more serious about this whole speaker building thing and experimenting with EQ/speakers/rooms I have decided the following:
1. The sound of any given speaker system is subjective - change the audio source - D/A converter, Pre-Amp, Power Amp, Room Conditions, Speakers, Temp, Humidity, physical or mental state of the listener and then EVERYTHING changes.
2. The Fletcher Munson Curves https://producerhive.com/ask-the-hiv...e-explanation/ are very real and listening at low level has a very different dynamic than those experienced at higher than normal listening levels.
3. Any sort of sound reproduction distortion causes Tinnitus to immediately become apparent/exacerbated - low distortion does not cause this problem - regardless of the sound levels.
4. Big speaker diaphragms driven at low levels in near-field listening are the best sound experience - subject to change. . .
5. Alcohol/Caffeine consumption changes the perception of detail in the sound reproduction of any given speaker system.
6. Commercially Recorded music is so variably mixed that no single speaker system is nor can always be satisfactory to the listener and adjustments to tone must be made when switching from one song/artist to another.
7. The "Q" of a frequency range of any given recorded song (particularly those below 50 Hz and around 20 Hz especially) must be re-balanced with its SPL and this changes from one song/recording to the next.
8. Fat (thicker speaker wire) does make a difference when you are fresh in the mornings and have not experienced the noise of the day as you are more sensitive/alert to subtle changes in the audio environment.
9. Music evokes emotion - good emotion is what you are after and it is found in the frequency range under 15KHz - keep that area distortion free as possible.
10. When you have assembled a speaker system when turned up to disturbing the neighbors level doesn't sound very loud to you but you can feel it - you have something to talk about and share with others as it is of low distortion/high reproduction quality.
11. Horn loaded mid/tweeters are under-rated.
12. The best 8" woofer is a 12" in over a 1.5 Cu Ft box lined - 1/2 filled with Pink Owens Corning 3-1/2" Fiberglass insulation for music.
Done.
Best!
