Best light weight full range speaker recommendation.

Gear with accurate treble, to me , can be tolerated for a short period of time.

I spend lots of time reading with the audio gear on

And its great with the Elac 2.0,/6.2 or the Epic

Epis on ! No fatigue

I'm done with overpriced gear and wish I knew this yrs ago

a great solution for speakers/equipment/listening room environment with biting treble or a harsh [bright] balance, would be a modern implementation of the old quad preamp’s spectral tilt control. wish somebody would make something like that nowadays. anyways, a nice relatively lightweight speaker would be those made by magnapan, their "magnaplanars." 

Take a look at rockport atria. Good luck! 

What I'd like to know is what is the reason the OP wants a light weight?  
If by full range he means no sub needed, that's a tough nut to crack. Inert cabinets with large or multiple woofers tend to be quite hefty. One brand that gets low coloration without too much mass is Dali. Look at Epicon in comparison to others. 

Full range AND light weight?  That's like saying Jewish space lasers started the terrible fires in Paradise, CA in the not so distant past...  Ya just can't have it.  Onto something more positive, a particular speaker that is small in stature that plays deeper than its size belies is the brand: Raidho.  I'm very impressed by this speaker, with the right amp of course.  It plays dynamically, deep, and oh so beautifully.  Going off topic here, I'm partial to Von Schweikert speakers, but they're big and heavy if the 20 hz region is what one is looking for.  Back on topic, a bookshelf that plays with some warmth is the Dynaudio Hertiage Special; that is one special speaker right there.  That's my $.02.  Good luck in your quest.
