the big one: how do you choose speakers? By what features, data?

thank you all, I am learning a lot. I was looking for key quantifiable data that would give me a decision tree - aside from price.

I think for a novice like me it has to be a trade off between accuracy and warmth and brightness and listening fatigue. Which I thought is in how the speaker performs at various frequencies.

@larryi can you list a few examples for dynamic speakers? What makes a speaker dynamic?

I think besides the questions above, I determined that I need

• not a lot of low end due to the type of music I prefer.
• no floorstander due to size of room, furniture, listening height
• a lot of detail, clarity
• "scratchiness" - I don’t have a better word. It’s basically about sounds to stand out and "matter" more to the ear e.g. when a singer stresses a note, it’s pronounced, or a piano key fills the room. Maybe that’s dynamics? It may be the opposite of flat but I also know it add to the listening fatigue. Which is a lower priority for me, I don’t listen to music for hours, I have 20-40 min, one LP at a time.

It's not that difficult. 

1) First, you need to decide on which speakers will work in your room. For any given room, some speakers just won't be able to perform up to their capability if they cannot be properly located. For example, a pair of panel (dipole) speakers need to be placed well off the wall behind them. If your room is too small to accommodate this need, you will never get your moneys worth from them.

2) Once you have eliminated those speakers that won't work in your listening room, decide which are best suited to the type of music you like to listen to. A little research will give you a general idea of speaker suitability for your music preferences.

3) Once you have narrowed down the list from steps 1 & 2, determine the amplification needed for the speakers to perform as designed. Some speakers require lots of current, others can be driven by only a few watts of power. Speaker impedance curves and sensitivity will dictate this. 

4) Now that you have identified the speakers that will work in your room and what is required to properly drive them, determine what you can afford. 

5) Most important, try to get a demo in your listening environment. How they sound to you is the most important thing but how speakers sound in an audio showroom or your buddy's room does not necessarily tell you how they will work in your room.

6) Finally, consider cosmetics, WAF, place of manufacturer (if that is important to you) and support.

When I bought my last set of speakers, I looked at the speakers that the maker of my amplifier used at the hifi shows. With the lac of shops in my area, it seemed a good way to go.

I think the two biggest things are your room and your actual listening habits.

Your room, and what you are willing or not willing to do to improve it matter a great deal.

Next, how exactly do you listen? Be honest! If you listen at low volume while working or doing other things, you should optimize and buy for that. Don’t go out looking for speakers that play the loudest and have the most rumble inducing bass if that’s not how you are going to use it. It’s like buying a car for shopping that you test on the race track.

Next, listen for a long time.  Lots of speakers are made to excite you in the first 5 minutes.  Few stand the test of just vanishing and letting you feel music for hours.

I think @jchiappinelli pretty much nailed it. I could digress on #2, but overall it's a sound (pardon the pun) approach.
