This is the history of a particularly inventive technician, Larry Hartke, who fiddled in the garage of his parents in Bloomfield (New Jersey) since his childhood. We really don't want to imagine what the world of technology had becoma without these cellars and garages... After his studies, the young Larry worked together for a while with a famous advertising specialist for audio material, a certain A. Stewart Hegeman. He wanted to replace the cardboard which was used until then for the speaker cone with aluminium. After testing his idea on speakers of stereo systems, he tried his invention on a bass amplifier speaker. At this moment he met a certain Ron Lorman in New York in the Bottom Line Club who is a sound engineer for numerous groups and musicians. They impoved the model together until Jaco pastorius, a regular guest of the Greenwich Village Club, asked them to produce him a speaker 8 x 10 inch with their well-known aluminium cone. Because of this invention, the sound become more exact, more clear, more energetic and received a better dynamism. It did not take more than that to spread the reputation of these two young man. That's why they created Hartke Systems. In 1985, the first catalogue presented the 410XL with 4 x 10 inch, a 15 inch, a 2 x 10 inch and of course the world-famous 810XL. The success of these speakers and top parts for amplifiers started immediately. The 3500 top part for basses is by the way the most sold all over the world until today. The Hartke line expand constantly with a equal security of quality and all this for a affordable price for every musician.
