These are awesome british made monitors..outstanding sound in a small package. I have the kube control designed to be used with them. It is an ideal speaker where space is at a premium. The manual says "Suitable for use with amplifiers capable of providing between 50 and 200 w into 4 ohms resistive load"
weight of each speaker is 15 lb.. size, 13" H x 8.2" W x 10.3" D. Suitable for book shelf (upright only) or stands
They are great sounding speakers...they become invisible when set up correctly and have great sound stage....very natural sounding...
The manual says
"...is efficient, easy to drive and has bass extension to 40 Hz... it is an ideal model where space is at a premium...creates the character of full size design with little compromise to power handling, sensitivity or loudness.... The dedicated KEF Kube gives the owner the freedom to site the loudspeaker wherever it is most convenient and can control to achieve a natural balance , compensating for the room..."
II've graduated to dedicated room and Planar Speakers with sub-woofers and that is the only reason I'm getting rid of them. BTW these are spouse approved.
