are they inductance sensitive

I honestly don't know. I don't have an inductance cooking system -- use a regular electric range. That sounds like something you'd have to ask the manufacturer.

I'm not totally sure on that one. I have used them on live wires without any incidents.

They have a low impedence of 32 ohms but have a sensitivity of 99db which is around 4db less than usual (which is huge in difference in db). If you listen loud, this isn't your headphone.

I dont think so. They are wired differently somehow from what I understand.

I would think so. Since they are rated at 89-90 for sensitivity and have 8 ohm impedance the Emotiva should drive them with ease. They drive my PSB Synchrony 1bs with a 2c center channel flawlessly, and those are not as sensitive as the Polks and are rated at 4-6 ohms.

Yes, they are!They are passive (don´t need battery) and I'm pretty happy with them.

I didn't have that problem with the ones I bought. They have worked fine. Might be a problem with one you received, or if you have a way to adjust your pre-amp some may help to corrext the isssue.

Yes they are. I didn't see any wires or batteries. Just mine didn't work from day one so I wouldn't buy it again.

These are great as long as you don't run a sub ohm build, anything below . 3 I wouldn't use then

They have an eight ohm impedance. The Polk website has a very complete list of the specs.

They CAN be hard wired. The important question is MAY they be hardwired. You need to check your local electrical codes on if, how, and by whom the work may be done.

I can't answer this, but they are cheap enough that it costs little to experiment. I suggest you ask an electrician.

In my opinion they're a little dimmer, especially depending on the color you're using. Definitely no hum though.

It seems like I recall that when testing the units, if one alarmed they all would. They worked fine. Mine just ate through batteries ridiculously fast even though they are hardwired to an AC power source

Just to see if they work, try using them individually and see what happens. The only concern I'd have is foreign material getting inside the jack holes and messing up the connections or that the prongs on the outside are perfectly intact. If they work for an entire day, you're in business I'd say; otherwise, these are not very expensive to purchase. Good Luck!

no. they would have to be rewired. i also own altec vs 2621. 2.1 they sound good. hooks right up. if that helps.

Mine were nicely soldered, not crimped. All read zero on the ohmmeter with no intermittent indications.
