Sundown SAE-1000D

Silver Member Username: SkiesCourtenay, British Colu... Canada Post Number: 585 Registered: Aug-05 | After looking at the manual for the 1000D, I did this one calculation and wow, I think Sundown is goin down the hole. With their 75 fuse rating & their published 86% efficiency: W = 14.4 x 75 x .86 W = 928.8 watts @ 1 ohm!! Even if it is a really efficient amp, it can't even do rated power. I'm quite let down by this, after all the hype about it and the 1500D b0ner... |

That's not unheard of, but it's really high. Also, it makes a big difference what impedance (ohms) that 86% rating is at. Most amplifiers' efficiency decreases as impedance is lowered, and vice versa. |

Silver Member Username: SkiesCourtenay, British Colu... Canada Post Number: 590 Registered: Aug-05 | 92.5% efficient everyday amp? I think it's priced too low to be that efficient.  Yes, that's true about less efficiency at lower loads. That could very well be efficiency at 1 ohm, or 4. Most likely 1, that would make it quite efficient at 4 ohm. Yeah, I guess they are priced quite well for the build quality. The 1000D CAN NOT do 1000wrms, due to the physics @ 14.4v. Stability at .5 Ohm is very impressive though. What is presale price, again? |
