how many amps will the LSi9 draw?

SlowcarIX

just wondering how many amperes the LSi9 will draw at their max rated power? voltage too?

There are too many variables to give a specific answer.:)The impedance of the speakers,the program material being played and the volume levels etc make it impossible to quantify.

Zero.

because the LSi9 will be dead near max power?

No, I think doro is referring to the fact that by itself (with no music playing), the LSi9's will not draw any power. Power is only sent to the speakers once the music starts playing.

hmm...maybe the question should be what is the max current the LSi9 can handle?

I don't know if this is accurate. But from what I have read, you can never have too much power when it comes to amps. Speakers are more often destroyed by underpowered amps than overpowered amps.

Underpowered amps will introduce clipping, and too much clipping will fry your tweeters.

Although I have seen pictures of blown woofers, I am guessing those are the result of cranking up the volume WAY beyond tolerable listening levels.

Thank you.:D

If you were ever to hear an amp at its max rated power, your eardrums would rupture, your amp would blow a fuse and the circuit breaker would trip. Even though you may blast your amp, you are not really hearing its rated power, and no where near its max power.

Why do you want to know?

The speakers themselves draw no amps. They determine the # of amps [and watts, voltage is constant] it will take for the amp to power the speaker and to answer your question as to how many amps they will handle? I dunno. Refer to my first question.

When reproducing a musical signal a speaker is drawing current from the amp.However because the signal is ever changing you cannot reduce the current to a single constant value.The speakers impedance and the frequency content of the music and volume levels are all varibles.

just wondering if the LSi9 will ever draw more current than these ICEpower500ASP modules in my amp will put out

With the potential to deliver 45amps on demand I don't think you have any worries.;):)

+1. Remember, watts are the key benchmark which all speakers/amplifiers are held in order. After all, watts equals volts X amps, right? So long as it is rated at 4 ohms, and has a fair number of watts (remember you want overhead), you should be more than fine running the 9's.

when an amp clips, what actually is most likely to happen? voltage or current limitation of the amp has been exceeded?

well..... you *can* have too much power, though it isnt likely in a home audio setting. i have witnessed *several* sacrificial speaker "tests" (for lack of a better term), where our primary objective was to destroy the speakers. one notable "experiment" had a pair of aiwa bookshelf speakers hooked to a 1000 watt pro-style amp. there was distortion, but it wasnt coming from the amp. wow, did that ever stink, lol. teenagers do the damnedest things, you know.

Clipping occurs when the amplifiers DC power supply voltages can no longer supply the full voltage needed by the output transistors during musical peaks.
