I have used similar Vapor Audio Nimbus speakers with my electronics at several shows and they beat everything else I had used in the room, so I had to have some.
I finally got them and they are amazing. These have new midrange drivers that are improved over the original Blacks and even the White ceramic drivers. The midrange is liquid smooth. Top end is crystalline clear. Bass is low distortion and extends to the depths of purgatory. A pure pleasure to listen to and a great match to my SET tube monoblock amps at 35W each. Very good off-axis response, so standing and to the side, you still get a good stereo image. Unbelievable for movies.
Not only that, they are simply beautiful.
I am now selling my original reference speakers, 4 foot ribbons with bass boxes and custom wiring and crossover components, including high-end caps and Jensen air-core inductors for a paltry $4K plus shipping. I also have 200lbs of lead bricks that I put on top of the bass boxes that I can sell, but shipping will be spendy. These lead bricks help with bass tightness. These ribbons are not like other ribbons. Very dynamic and extended. Crossover is at 650Hz. These can actually create an acoustic shock wave. They are efficient enough to use with 30W tube amps and drive well with 4 ohm transformer output. The off-axis response is excellent. This is why they are great for shows. They break down into the panels and the bass boxes to ship in 4 boxes.
