Hi . I am Darek from Warsaw. I am self-taught and my hobby is designing and building loudspeakers and amplifiers. Of the latter, I like the Mosfet Single Ended constructions the most, because I managed to design and build some of them (with light bulbs instead of a current source). When it comes to loudspeakers, my first Open Baffles with 15 "Eminence EM15-100 and Oxford 6x9" broadband speakers are about to be built. My workshop has recently acquired a measuring system for loudspeakers and room acoustics, and a router. More and more people are asking me to build speakers, and it takes a long time to make holes by hand so that the speakers are flush with the board. In turn, a professional carpenter counted for 8 holes as much as a milling machine in a supermarket. I hope that the exchange of our knowledge will be very fruitful, and I will gladly try to help everyone as much as I can. Best regards from Poland
