Judging speakers to purchase.

@knottscott , can you expound upon that?

Hoping to discover more regarding the sound that the speaker has. Thin, forward, bottom heavy...feel free to use words like rich midrange and organic sounding and realistic presentation...

Transparent, balanced, and natural sounding with a believable 3D soundstage and imaging if it’s in the recording.  To me, if you sense you’re listening to speakers or something they’re actively doing instead of feeling like you’re just fully and effortlessly experiencing an unfettered performance then something is wrong.  That’s my take anyway and what I’ve always strived for in building/improving my system. 

Speakers are the only component that can affect sound radiation pattern. There are qualities not found in “typical box speakers” that you find in varying amounts in dipoles/bipoles/omnidirectional speakers/open baffles/wide dispersion box speakers. If you haven’t heard any from these categories worth a listen before you decide. Huge soundstage and they disappear.

In a nutshell, the idea is to create a music wave that sounds natural when it reaches your ear, as if it’s coming from a single source. For example, splitting the female voice between a woofer and a midrange means creating a uniform wave from two sources, so the timing of those two drivers to create the illusion of a single source poses challenges, or it won't sound natural. The slope of the rolloff of both drivers and the crossovers all come into play, along with reflections of the baffle. One of the appeals of full range drivers is that they are a single source, though there are other downsides, as there are with every option...never a free lunch.
