The Sound of Speaker.


Before going to the journey looking for a best speaker that suit our ears I think we should separate them first.
It seems much easier to find it if we listen to Regular 1-2-3 ways Box-speaker or Electrostatic Ribbon Panel or Horn speaker. Generally one-type of speaker have the same sound characteristic.
But those 3 different type very much having big different sound characteristic.
See and listen to all first, then narrow it down to whatever type that suit our ear best.
As my journey has ended at a Horn-speaker.
Just my 2 cents.

I see you're trying to get at categories of sound that go with categories of speaker. This is an overgeneralization, but it's not completely wrong. My experience of listening to box speakers vs. electrostatics vs. those incorporating AMT ribbons vs. dipoles showed some pronounced differences which was partially attributable to their approach. 
Horns are fun and some of the real good ones. Everest, VOT, Jensen Imperials, Have some of the nicest cabinets made for their time and now if your into HUGE (normally) ply cabinets..

Me I’m a small planar guy. 3-10" or so.. 8" Monsoon neos are mighty hard to beat for speed, accuracy, power handling and frequency range

The new GSRs can work from 300hz to 20Khz 50 watts continuous power.. and 49.00 usd per unit.. EASY load... Wire them at 8 - 16 ohms and drive them with an A or A/B valves amp.. 20-200 watts they don’t care..

I’m pretty fond of ring and domes too. I think for rock and roll one of the best speakers I heard were Infinities QLS1 40 yeas ago.. Man you get those to sound good.. They use to fill the base with sand and tune that Watson to the room. Came with different resistors for ceiling height..

As a matter of fact I have 24 just waiting for a nice narrow baffle about  about 8" wide.. A single AC G1 ribbon for the highs.. Maybe 72" tall. Two railroad ties stacked aught to work.... :-)

YUP... Time to feed the chickens..

Or better yet ignore anyone posting condescending or other discourteous posts. I enjoy my time on AudioAficonionado forum because non courteous behavior is not tolerated and the forum emphasizes high end systems.
@OP,
When I was a student, with limited funds, I bought inexpensive drivers and built my own speaker cabinets. I learned about the very basic stuff to make speakers which allowed me to use an inexpensive receiver and a turntable to play through the pair of DIY bookshelf speakers. 

In the meantime, I look at reviews and tests, and go listen, in search of the 'perfect' speaker. As a person trained in the sciences and engineering, well as in music, a speaker must test well - not just the linear tests, but the non-linear tests too. Then I listen to speakers and it must sound real, enough to convince me that I am hearing what I expect to be real without having to concentrate to hear it. The speakers should also be listenable over many hours without fatigue. Too many speakers fail this last test, while giving a good initial impression.

It doesn't matter what technology is used to reproduce the music - horns, panels, cones/domes, ribbons, AMT, etc. If the final sound waveform is a facsimile of the input waveform, then that's the best you can expect from the designer. If testing shows this is so, and the sound tells me it sounds real, then I'd buy that speaker (if I can afford it).

Also, consider whether you will listen to the speakers for two-channel music, or will you also use it in a home-theater 5.1-, 7.1-, or more channels arrangement. If both, that could limit your choices in which speaker design you use. Good luck in your search.
