What is the total cost of all the hardware for building a pair of PHOENIX loudspeakers?
A11 – The material cost depends, of course, very much on your supply sources. Here, in the USA, I would estimate the material cost as follows, but please do not hold me to those numbers: 4x 1252DVC $200 4x 21W/8554 $600 2x D2905/9700 $400 (2x D2904/9800 $400) Electronic parts & 2 pcb $400 Power supply $100 XO/EQ chassis $100 Cabinet material $250 This totals to $2050. Add to this the time and cost of your labor building it, and the cost of tools and equipment, unless you own those already. In addition you need 6 power amplifiers which might cost you $2000 or more for a 6-channel, 150 W per channel, amplifier. You can save considerably on amplifier cost by building your own using the LM3886 power op-amp integrated circuit. 3886amp.gif You could sacrifice some performance and save about $700 by using the Vifa P21WO-20 and D26TG-35 drivers instead of the Scan-Speak drivers. The PHOENIX project, though, is not about building an inexpensive speaker. My goal was a loudspeaker that gives you
