What are you 'TRULY' Looking for in Loudspeaker...

TRULY? Are you for real? You mean TRULY?

Tall, thin, protuberant tweeter, big woofers, tight bass, fishnet grill, spiked feet, leather baffle, three ports, exotic cherry hard wood finish, active and dynamic with high sensitivity, and never need maintenance.

Oh, one more thing, and this is really a given for a speaker, it should never have a headache...

Shadorne>> your description is just about the same as mine...for my ideal woman! Just add push-up bra, hair color and swish of the hips when she walks and you've got her nailed perfectly!

When I read your question I didn't take it that you are looking for advice, just curious as to others thoughts. So here are my thoughts.
To the extent my budget and time allowed I have "studied" this in the most thorough way possible. Found Audiogon almost ten years ago and began buying speakers for "study" in with my ears. What I have found is that I want a speaker that I can listen to for hours without thinking about the speakers, system or any other audio related gotchas.
Although I can't imagine not looking for something better, I do believe I have found what gives me all I want. I can listen for hours (if I ever have the time) and while doing this I keep turning it up just a smidge more without it irritating me. This isn't possible with most of the speakers I've owned. In fact, I recently purchased a pair of monitors valued at more than 3 times my current monitors and I kept turning them down to save my ears. They had way too much of the "audiophile" flavor.
How many speakers have I owned? I swear I could not answer that question with certainty.

For the reproduced sound as close to unamplified vocal and acoustic guitar including bass guitar as possible. And I pay attention to size and price.
