Hello everybody, my name is Peter and as have probably guessed I'm a bit of a JBL nut. I work in the TV/Radio Broadcasting industry as Snr. Broadcast Technician. I have worked in this industry for about 20 years and in the electronics industry for about 25 years. I install and maintain High Power Digital Television Transmitters and have extensive background in RF/ Satellite and microwave. I have been very interested in the audio arena since I was about 15 (30 years ago). About 10 years ago I decided to make the ultimate so I set out and accurately repoduced a set of JBL 4430's and 2 BGW 250D power amplifiers (after redesigning printed circuit boards and added self designed logic control board to monitor Power Supply Integrity, DC Offset and Clipping) and a repoduced JBL Active cross over network to complete the system. Jsut getting itchy feet again and am now looking to upgrade but not sure what to.
