The main disadvantage is generally cost and modularity, the advantage is simplicity. With an amp and passive speaker system, you can invest separately in a good amp and good speakers. You can upgrade one without the other and you have more flexibility in how you can upgrade. Also, generally, higher quality combined speakers will be more expensive than ...

Whether it its a sine wave or not is almost irrelevant. I say almost, as if you do hit a resonant frequency you could destroy something else in the room - theoretically... you would need power to do this though. You did not destroy your laptop speakers because you played a sine wave. You may have destroyed them because the volume was too high or there was ...

Thanks for an interesting question! This kept me awake for a while. It is definitely possible to generate chords even if all you have is a one-bit signal to the speaker. Many games for the ZX Spectrum (3.5 MHz, 8 bit CPU, 1 bit speaker) did this in the 80's. There are a few techniques I can think of: Just generate (sine, square etc.) waves of different ...

You might want to look at some of the theory behind additive synthesis - this Wikipedia article simplifies some of it. It is definitely do-able. Of course, using a single bit (ie speaker at position 0 or position 1) will add in some interesting harmonics which will vary depending on the maximum rate of change of your speaker cone and the maximum rate of ...

You should worry just as much about protecting your equipment from humidity. Humidity will affect the speaker cones, the electronics inside, and everything else too in more extreme cases. Changes in temperature will cause expansion and contraction. Since different materials expand and contract at different rates, that can break down the cones and the ...

I called the number above, then was told by recording I needed an AVID support code. I pressed "2" and actually talked with a customer support rep, and was told to email my request to "repairs@m-audio.com" BTW is tried several times to get this email address from the M-audio website but was unable to find it.

Most stores and malls will use an inline array running at 50/70/100 Volts with a VERY bandpassed signal (probably 300Hz-8kHz, not that much more than the audio bandwidth of a telephone call). This allows the signal to be more easily amplified but sacrifices a good deal of fidelity - the speakers will be designed to reproduce the same frequency range for ...

A powered speaker will generally cost more and be heavier, since they integrate the amp. If you are going with 4 speakers, and want flexibility in adding more in the future, it may be worth it to go passive. Behringer makes some nice 4 channel amps that are lightweight, look for the iNuke series. I have 2 of the 10" Behringer active speakers and they are ...

You can do this either with two sound cards and software to use each one (per imsky's answer) or with one sound card that has multiple stereo outputs. If you take the one sound card route, you'll need software that can send your music (presumably MP3s or something like that) out to the disparate outputs. It sounds kind of like you're looking to DJ a party, ...

I may have stumbled on a better way to contact M-Audio, that I will try next week. I can order parts from their repair department. For anyone interested, here is their info: Call 626-633-9055, press 2 at any time to bypass the introduction message, and then press 2 for replacement parts. Mon - Fri, 9am - 5pm, Pacific Time
