The device supports high-resolution audio signals, which more closely resemble the quality of music as it was originally recorded, with more texture and detail than can be heard via typical music streaming services or CDs.)

Q: What is a 2-way speaker? What is a passive speaker?

A: One speaker for high frequencies and one speaker for mid and low frequencies. A passive speaker is not self-powered. You must connect them to an amplifier with speaker wires to power them.

Q: What kind of hole(s) do these have in the back? I want to know if they work with my existing wall mounts.

A: There is a single hole in the back at the top of the speaker. It's a fairly heavy speaker though. Use a good screw and one of those expansion things (sorry, don't know what that thing is called) that you stick in the wall then drive your screw into that. Hope this helps James N. Merry Christmas

Q: can these be used as both front and rear speakers in a surround sound system or do you need or are there bookshelf speakers designated for front and rear?

A: I'm using these as rear surround speakers. Im sure you can use them as front speakers too. These are a little big. Maybe the Polk S10 for rear surround and The S15's for front or maybe tge S20's for fronts.

Q: Can I connect bare speaker wire into the back of these? I have an old receiver.

A: Yes and it did do the job for me. Very simple button mechanism to hold the wire. Don't waste money or time buying jacks or anything. Wire, speaker and receiver all you need!

Q: Is this price per pair?

A: Yes. This price is per pair. The title is definitely misleading. It even confused multiple store personnel. To top it off, the box itself only has a picture of a single speaker. Before I purchased these tonight after some debate we eventually opened the box which revealed it has two speakers in it.
