Are the JBL ES20 powered speakers? Do the speakers have self-contained amplifiers?

No... But they are the best 3 way speakers at a more than reasonable price. They are not for computers but even the cheapest receiver will pair up for excellent sound

They are passive speakers, which means that they are unpowered and you need an external AMP/AV receiver to power them.

As others have answered, these are just passive bookshelf speakers. If you're interested in powered speakers, a more worthwhile category for you to browse would be active monitors. http://www.amazon.com/s/ref=nb_ss_gw?url=search-alias%3Daps&field-keywords;=active%20monitors

These are not powered speakers. They are standard speakers with input for speaker wires coming from the stereo amp/ tuner/receiver at whatever voltage that runs on. I hope that helps.

need an amp of some sort. Be careful - not "these!" Unless things have changed this is not for a pair. When I purchased it was for one speaker only. I just read the other guys response and I have no idea what he is talking about. These are ABSOLUTELY not self amplified.

no, these are not powered speakers and the volume would be controlled with a powered amp (stereo receiver). they have a very nice white grill. you can't see the speaker with the grill.

I answered 'yes' by mistake - it is not necessary, so there is no confusion. The speakers are self powered, you simply need to plug them in from the speaker with the power cord to a 110 outlet.

The speakers are excellent. They are not active speakers, they require an amplifier to drive them.

the speakers are powered and can take a powered line in. most dj's will have a powered mixer board for output. We have tied these speakers into a Peavey 1200 watt amp

No! Everything comes separate. Stands cables ect! All you get us the speaker and the box. These speakers are great for low volume. Once you then it up to a level you want to party to they start to crackle. Do your homework I lol more and maybe save so more money to buy better monitors than these. They make them with 1000 watts now so maybe they sound better then the 600 watts one I have. Save your money buy the jbl eon615. Gonna do you more justice in the long run then mackies. Mackie only offers the basic warrenty too btw. Do your homework bro

these speakers are just speakers, and still need a amp/signal source. When i got these several years ago, it was part of an amazing Amazon offer that included a yamaha home theatre system, that still rocks today. You'll be happy with these speakers, but you need more stuff. :)

Depend s on what your using them for...the es20 n 30 are bigger speakers and are mostly used for fronts...i think they would be over kill for surrounds. But the es10 are nice n slim and don't take up much room...they could be used for either fronts as they have the power n are 3 ways or they could be kick ass surrounds. They have a good freq rage as well. You can't beat the price either way you want to use them. Hope this helps

If you are asking this question in relation to these speakers than no. You have to have a receiver/amplifier to use these speakers. Also I am not sure what the reviewer below me had a problem with. I have owned the entire JBL Studio L lineup including the JBL L820's, and they have performed flawlessly for going on four years now. Excellent speakers!!

They don't have a wattage rating because they are not self-powered, but rely on a separate amplifier. The speakers are rated at 4ohm. I use the Audioengine amp to drive mine. There is plenty of volume and they sound great - much better than any other computer sound system I have owned.

Nope, these are completely stand alone speakers. You need a reasonable stereo power amp of at least 30W per channel (I use 100W plus equalizer because these speakers sound so lousy) to drive these speakers. Of course, you can plug a 3.5mm jack /dual RCA output cord into the Ipad and your amplifier/receiver, and you'll be good to go.

These speakers have no amp built in; they are just speakers. They also happen to be great speakers. You can connect them to a computer using a computer sound amplifier system or you can use a stereo receiver, but whatever you use must have connectors for plain speaker wire and can't be hard-wired to its own speakers. I use four of these TSi-100s connected to a Logitech Z-5500 speaker system, and I couldn't be happier.

They are not powered speakers if that's what your asking. Pair them with a Lepai 2020 amp ($20) and you could hook it up.

The 151 SE speakers are passive speakers. They are designed to be powered by an amplifier or audio receiver. A Bluetooth device could potentially be used as an auxiliary device with the amplifier/audio receiver.
