 After reading the specs, I e-mailed crown with some questions. Here's Crown's response.
"Mr. Behr,

The amplifier's DC protection will disable the power supply at 7Hz.
<< Do you have a Power-Bandwidth spec for it? >>
We guarantee the frequency response from 20Hz to 20KHz. Because of slew rate limiting the response begins to roll off at (roughly) 29KHz at 6 dB per octave.

Yes. This is common practice. There is a limit of 15 feet (5 meters).
If you have any further questions, please write.

I ordered a CDi 2000; we'll see. With a power rating of a kiloWatt per channel into 2 Ohms, it sure ought to drive that IB supersub. |
Have i read that wrong or do these amplifiers have a wall at 7Hz? Bossobass over at AVS with his argument that sealed boxes with proamps are the best for infrasonics has just failed
Very interesting... So the people building sealed subs for 10hz and down are gaining nothing
Presumably if crown does this then many others probably do aswell
Very interesting
