The Schmitti Memorial, an unusual speaker with high efficiency and lots of power, was developed by Christian Gather and Holger Barske.
The project was initiated by Heinz Schmitt, the late editor in chief of Klang+Ton. Now, the staff of the editorial office completed this project to honour an commemorate Heinz Schmitt. The goal was to design a rather unusual, not just a run-off-the-mill speaker. And certainly, the team succeeded in doing this.
The following driver were used: - Mundorf AMT 2830 Air Motion Transformer - PHL 2520 midrange driver - 24 inch Precision Device PD 2450 bass driver by Cantare
The 61 cm bass driver with a voice coil of 150 mm diameter is capable to generate low bass with high efficiency in a 360 litre cabinet. It was quite difficult to find a matching midrange driver. Eventually, we came across the PHL 2520, a PA midrange driver distributed in Germany by Achenbach. To shift any possible baffle step effects to lower frequencies the driver was equipped with a circular front plate.
Excerpt of the Klang+Ton review in 6/2006:
... "Despite a relatively unobtrusive appearance, the enormous bass driver
diaphragm suggests that an unparalleled inferno will befall the poor listener
when the volume is cranked up. How wrong. The Schmitti Memorial has not been
designed as a PA speaker dressed up in a hi-fi outfit. Don't make the mistake
to judge the tonal balance by the distribution of driver diaphragm areas.
The 24 inch driver behaves a lot more civilised than expected. In the first
place, the Schmitti Memorial is a high resolution speaker with real monitor
qualities, not just a dumb and slow low bass hooligan. Clearly, the midrange
driver and the tweeter are calling the tune, the bass driver is just a supplement
- that's it. Large diaphragms usually indicate high energy, and here the PHL
midrange driver proves to be the ideal partner for the energy brimming AMT.
Purity, clarity and a subjectively loud but disciplined way of playing are
properties of this tweeter. I tend to talk about course dynamics, although
this sound a bit strange when talking about a high frequency driver. The PHL
is complements this exceptional tweeter without leaving a gap, ensuring a
deep insight into the musical events. You can call this performance direct,
frank and even a little merciless - lovers of classic, British miniature monitors
might have their problems with this one. The bass driver's big moment arrives
when authority is needed. There are no big bangs as sometimes heard with horn
type speakers, but large drums are reproduced in a way I have seldom experienced
before. But then, this is not a big surprise, since a bass drum has a similar
radiating area to the driver's diaphragm. The reproduced size of those percussion
instruments is just perfect, only for that reason this enormous saucer pays
off. Low frequencies need space. Is the listening position closer than, let's
say four metres, then the reproduced sound stage is far too big and spectacular.
Moving further away from the speakers the sound become more integrated, almost
detached from the speakers and might even become small and intimate. Within
limits the sound character may be altered. In my opinion a transistor monster
would only be an adequate partner if demolishing of building is one of your
hobbies. However, to really enjoy music this speaker should be partnered with
either a Class A or valve amp. Since the subject of cables at 96 dB is irrelevant
we could also try one of the single ended triodes. Our tuned Dynavox? Connected
to the Schmitti Memorial this amp means business. It's certainly not a combination
for sensual moments, but unbeatable at a party. This is an extreme loudspeaker
in every aspect. Since the pace of this speaker is not really decent, handling
could become critical. But now we have come full circle with the person lending
his name to the speaker. Heinz Schmitt was also a man of loud and clear words,
he also had oomph, even though he didn't display it openly – just like this
loudspeaker. The editorial office of Klang+Ton would be pleased if this speaker
could conserve some of Heinz Schmitt's virtues and see to it that his remembrance
is kept alive." ...
