Best light weight full range speaker recommendation.

Oh one thing to ad, I've replaced a few subs to the KEF KC92 they are super light and they don't vibrate at all due to the drivers cancellation themselves out 

I hope this helps. Wilson sells-or gives to the buyers- smooth, metal, saucer

shaped discs with a small impression in the middle which the metal leg points

fit in. I am told by someone who knows that this is the easiest, and safest way to

move heavy speakers on carpet. If you have a hard surface they have a model

with some type of fabric on the floor side.

 I use 4" vinyl coated wheels to move my speakers in place. 

I know from others who own older "Tubby" speaker that wheels  are

often employed. 

Joseph Audio:

PULSAR2 Graphene $9k compact but gives relatively satisfying bass 36lbs each

PERSPECTIVE2 Graphene $15k floorstander 85lbs each

Lots of positive reviews.

Doesn't buy into the weight argument.  Hopeless. Have fun with it anyway.   :)

Vivid Kaya 90s are 87 lbs, the Kaya 45s are only about 57lbs.  "Full Range" is tough but they both extend well below 40hz and will give very satisfying bass and are easy to place.  

Even lighter is the Spendor D line.  The D7.2 is 48lbs while the D9.2 is 80 lbs

These are the lightest larger speaker that I know of.
