All the Ground Sound modules were on display
- and even the new Coolback II 600 could be seen for the first time
I would have liked to make the measurements of the AO in the K+T measurement room, but a simple mistake made us believe
that the new XOverWizard II had a bug giving a slope of about 6dB/oct. High Pass in the whole frequency range. An hour
before the Hörtest participants would arrive – I gave the new XOverWizard software one more shot. Ha – no bug – a simple
wrong connection in the microphone amp/mixer. Above you can see the measurement setup – Microphone + stand, mixer amp,
some wires and laptop. The software worked perfectly - below some screen shots. The XOverWizard II software is actually
capable of measuring in a “normal” living room, because the sophisticated “multi-win” tool is able to "take the room out
of the equation".
The “multi-windows” are the pink area of the PIR window in TIW200 and 18W/8545K00 measurements.

The "automatic" setup of the AO loudspeakers is shown above. Unfortunately, Christian had
to stuff the reflex ports to get a tighter bass, as the listening room at K+T has a giant peak
(room mode) at 31Hz. I forgot to remove the stuffing from the port before I made the XOverWizard II
measurements. This way I didn’t get the right ported response. Afterwards, it would have been easy to
get the “right” tight bass response by removing the room resonance with a notch filter (31Hz – Q=10-20).
This is an effective tool to get an authentic / strong bass without room. If the bass is right
– the tonal balance can get right too and an aggressive sound is avoided... - and the sound image will still be intact!

A view form the listening position - we are ready to present the AO |

All seats are taken - people are listening intensively - sometimes with eyes closed ...

Yours truely, Robert GS, at the Laptop and Christian Gather pointing and explaning how everything works
The Design Amplifier "OP" was used for the passive and full-range loudspeakers
The nice weather permitted "listening in the garden"
When you listen to a system outdoors it does a lot of "good" to the sound (=no wall and ceiling reflections)
K+T has an expression for their cheap loudspeaker projects called Cheap trick # something
- Listening outdoors must be the best cheap trick there is at all...
A few men can't get enough and listen to music and loudspeakers into the evening hours
