I have heard/reviewed a couple of their bookshelf speakers and liked them.
However, I heard one of their flagship speakers where the tweeter below all of the other drivers for some bizarre reason and they did not sound good. I wonder if the designer of that particular model accidentally turned the cabinet upside down when marking the build plans to put the threaded inserts for the feet
I think you are referring to the Dynaudio Consequence speakers.
I have history with those. They first appeared in 1984, they were later revised and the drivers changed to the esotar range, and the isobarik bass unit enlarged a little.
The reason for the driver layout is because these speakers use first order filters and are time aligned. This means the lobing tilt axis is upward.
All the early work was done on these speakers while I was developing my previous studio speakers, started in 1976, and went on for around a decade. I was following a similar path and used three Dynaudio drivers. The M75, D52 AF and D21 AF. In 1984 I used my first modelling software in an Apple 2E computer! Anyhow those were early days, and I had generous help from the good folks at Dynaudio. Despite computers there was a lot of touching up by ear!
Anyhow I made mine taller and had the tilt downwards. I'm still using these speakers.
The bass section is 2 KEF B 139s in a TL. The crossover to the M75 is active at 180 Hz. This is not first order because of the violent resonance of the KEF units above 900 Hz.
The other crossovers are all first order. The Dynaudio team suggested the unusual series network for the cross from the M75 to D52. There are just seven components in this passive crossover.
The M 75 is in a totally damped line.
The tweaking of this crossover and driver offset went on for years. However they became really nice speakers. Bob Carver spent an afternoon with them when he was in town setting up an early pair of his ribbon speakers for a cardiologist colleague. He really liked those speakers.
When I moved out of Grand Forks, I did not want to scrap them and rebuilt the bass line to take advantage of George Auspergerer's mathematical TL model.
The dispersion pattern of these speakers is ideal for HT in that position and they really get to shine in works like the SACDs of Britten's War Requiem where there is a large orchestra up front with choir and large orchestra, and Owen's war poems sung from the rear where there is also a fairly large chamber orchestra and children's choir.
I did get to hear the Dynaudio Consequence speakers at a Stereophile audio show at the Waldorf in New York in the late eighties, and got to meet the Dyanudio people. Prior to that it was all snail mail to Denmark. There was no Email then!
I did like the Consequence, but the sound stage was strange. There was the unmistakable feeling of the sound coming up though the floor! On mine there is a much more convincing concert hall presentation.
The Dynaudio Consequence is still on production but not advertised by Dynaudio, Last time I checked price was $70,000 per pair, but probably higher now.
