Loud Popping Noise at Startup.

My Altec Lansing ADA 745 4.1 Speakers seem to make a popping or thudding noise when I first startup up my Dell 4100. It's a really loud thud, it's more annoying than anything. But I'm afraid it's going to bust my speakers. It's louder if I have the volume up louder when I'm booting up. Sometimes I forget I have it really loud and when it starts up the thud is really loud.
I think I read somewhere that it's the internal audio amplifier turning on/off which causes the speakers to pop. It's the amps sending a power spike to the speakers when the desktop is first turned on? This also happens when I have them connected to my TV's audio out. The speakers pop when I turn on the TV.
What can I do about this? Is this a design flaw? My specs are below.

That is typical for many amplifiers or in this case "powered" speakers.  You will just have to make sure the volume control is turned down or turn the speakers off until the PC is powered up (or turn on the TV first then the speakers).

This happens in many guitar amps too.  I had it in a Peavey amp but it never caused a problem.  Some high end systems have built in delays so that the power supply will come up to full voltage and "settle down" before the time delay relay kicks in and that prevents most "pops".

So basically there is no fix for this at all? It's really annoying, and I forget about turning off the speakers all the time. I'm used to leaving them on, all the time.
