Die Schnecke, Pico Lino 3, Cobra Horn, Transmissionline TL90, Micro-Horn 2015
HOBBY HiFi 5/2015
Extra-large edition with 114 pages.
Presentation of the design horn "Schneckenhorn" engineered from Bernd Timmermanns, idea and realization from Vincent Schwall. The 8" fullrange driver W8-1772 from Tang Band is used.
In addition there are a lot of presentations of horn and transmissionline projects. An extensive test of fullrange chassis is also included.
Desktop TL and Studio-Monitor 2
German magazine HOBBY HiFi 1/2015
Development of the miniature Transmissionline "Desktop TL" with Scan Speak 5F/8422T01 driver..."With all these presuppositions AJHorn hits the target. Already the first trial construction could not more improved."
Some words from the real developper of the "Studio-Monitor 2" from HOBBY HiFi 6/2014
Many informations about the practical development and optimization of this horn system.
"Mini-Transmissionline TL90 und BK166 Horn Enclosure"
German magazine HOBBY HiFi 4/2012
"Without simulation possibility, the construction of a Transmissionline loudspeaker would be a hardly yet realizable venture - until the construct perfectly functioned, could be processed many square meters of chip disk and to dispose of the most therefrom afterwards. HOBBY HiFi has worked for many years successfully with the software "AJHorn". Whose results we exactly can confirm fair technical again and again ..."
"... If one very exactly takes it, the BK166 resembles at the beginning sooner a hyperbolic and to the end there sooner a geometric horn course. The simulated frequency responses show between both horn types however no significant difference - last of all is it therefore insignificant. Here now the result... That can see let itself: Until 200 Hz, the agreement of measurement and simulation is impressively."
First view on the new version 6 from the german magazine HOBBY HiFi
"... The housing input window was formed newly. The number of the housing parameters grew at the same time considerably. In order to retain here yet the overview, the input fields are arranged at corresponding positions of a horn principle sketch. ... Once therewith trusts, prepares the operation of the program no difficulties at all. Horn systems with two different drivers, two way Subwoofer with one closed and one bass reflection department, simply or doubly ventilated bandpass systems, all that and yet much more succeeds effortlessly."
Comment: The graphics problem of the horn input window shown in HOBBY HiFi was solved in the meantime.
Reflex-Horn-Hybrid with 103 dB/W/m and 18-Inch driver.
"...One day AJHorn spat out now the reflection horn hybrid housing introduced here for the AWX-184 18-Inch driver by Mivoc. On the paper, the horn with very high sensitivity and orderly Bassperformance made an outstanding figure in relative compactness."
"...now the horn stands here and bolsters the theory mark shaking with practice."
"Jericho 08" in HOBBY HiFi 2/2008
Fullrange horn system with Ciare-driver
"The bass horn was designed with AJHorn. In addition to the area at the beginning and at the end of the horn and the horn length this simulation program offers the possibility to take into account the influence of the pressure chamber and the absorber chamber, that can be used to swich off troubles in frequency response."
"... That a pressure chamber has sometimes more disadvantages than advantages shows AJHorn: there is at low frequencies with growing pressure chamber a more wavey response of sound pressure. This one can recognize as a lack of low frequency volume ... therefore the version 08 of the Jericho-Horn does without a pressure chamber."
