Why do you ask?

If you are thinking that the amp IC inside these things is something amazing because they are rated for 1500W and cost something like $90, do some research on PMPO power ratings. Any amplifier manufacturer that markets their products with PMPO power ratings has nothing worthwhile inside the box.

If you're just shopping for a computer speaker system and don't want to DIY, I'd look at Altec Lansing, and also Logitech just because they use Tang Band drivers in most if not all of their speaker products now.

I think PMPO is the wattage that flows through the speaker when the amplifier shorts and the cone is launched across the room. Of course, it's only for a tiny second.

20 watt computer speakers with a powered sub would be perfect, any thing more would be ear piercing. I had a pair of Altec Lansing ATP3's and they were 15watts and PLENTY of power. Wish i still had them

Logitech makes really nice speakers now. Altho they make a 500watt system too for a enormousness amount of money.

Logitech does make real good computer speakers now (not as good as DIY however ), but their power specifications are almost as bogus as a PMPO rating. Several years ago before I knew anything about electronics I had a set of Logitech Z-560 speakers. These were one of the first models they made when they started making good speakers with Tangband drivers in them. Anyway, the speakers are rated for 400W RMS which is completely bogus. The amplifier consists of 6 TDA7293 ICs (1 for each speaker and 2 for the subwoofer). However the Tangband drivers in the satellite speakers are rated for 17W RMS, and the subwoofer can handle 100W RMS. So at most the system is 170W, which is far short of the 400W advertised.

I felt like I had been taken for a fool when I found this out, because I specifically chose this set of speakers over the competing Altec Lansing model because of the higher power rating. I guess the Klipsch speakers were more expensive for a reason .

I'm not a klipsch fan at all. There home speakers sound horrible.

Altec's are nice.. Power is used as a buying feature.. WOOOO look here they are 10,000 watts.. mean while you simply look at the speakers with a small 500ma 8v power adapter and wonder where the hell 10,000 watts comes from.. HUMMM makes me wonder how they figure this out.

self built is always better

I have to admit I've never actually heard a Klipsch speaker first hand, but had listened to a pair of $1000 towers in a store and didn't immediately think of horrible. It's hard to tell in a store though. I actually kind of miss the old Logitech computer speakers. They died of a catastrophic amplifier failure, though I did get some good parts out of them. There was a decent sized 48VCT toroid transformer, a couple of 10,000uF caps, 4 amp ICs that didn't blow up, and a few nice little Tangband speakers that have been collecting dust in my closet for a long time now. This summer I'll put aside some time to build a box for them (a copy of the old ELF speakers so many enjoy) and use them at my computer with a little Tripath amp (I'd call it a Sonic Impact amp but there's not much left of the original product besides the amp IC and output filter).
