I am spec'ing a background music system with Turbosound speakers and Crest amps. The are two zones: 1) A large outdoor open area which I want to cover with 4 x Turbo TCS-121C 12" speakers at four corners. The cable length from the amp room is about 100M (330 ft). These speakers can be ordered with a 70/100V transformer option (the maximum tap is 120W). 2) A smaller space for which I want to use 8 x Turbo Impact-65T speakers. This area is about 50M (165 ft) from the amps. These speakers also have a 70/100V transformer (the maximum tap is 60W). I have no experience with 70/100V lines, but it seems to me that because of the cable length I should go this route. My questions are: - The speakers can work with both 70V and 100V lines. Crest has amplifiers for both 70V and 100V. Which should I use? Are there any advantages for using one type of system over the other? - Which amplifier power ratings should I use? I would like to have the speakers operate at full bandwidth (without high-passing). - Which cable gauge should I use? Any advice would be helpful. Thanks, |

Thanks all for the replies, I now have a much better understanding of what is needed. So, according to Robert I could use 1 Crest 9200 (1300W at 8 ohms)? I have that in stock and it would be great if I could use it. |
