Best light weight full range speaker recommendation.

Goldenear Triton Reference, 12hz-35khz, around $10k, 110 lbs. (class A in Sterophile)

Wilson SabrinaX, 31hz-23khz, around 20k, 112 lbs.

Focal Sopra 3, 33hz-40khz, around 20k, 154 lbs.

I still do not comprehend why you care about the weight at this price point.  (So you could move them around in your living room?)

Kef Blade2 (77 lbs)

You might try the ATC SCM40, I think they weigh about 60 pounds each (I have the SCM35's). They punch well above their weight in price. A3 Magicos are what I would do above these- they weigh 110 pounds.

Gershman Avant Garde.

You should look at the monitor audio Platinum 300 Gen 2 Robert Dortch of stereophile after listing to them bought them as his new reference the whole Platinum lineup is incredibly good sounding.
