Wireless speakers questions

two questions: are wireless speakers synonymous with active (i.e. passive require a hard-wired amplifier)? And how do you use wireless speakers with a regular amplifier. Is there a wireless module connected to the amp to transmit to the speakers? If so, what is it called?

Wireless speakers are active speakers, there is usually a transmitter from the amp or some kind wireless play system.
The later is more for the newer amps.

Yes, wireless would generally be active. There are various wireless protocols but one issue to watch out for is that the usual public ones (like over Bluetooth) are lossy. I *think* technically Bluetooth does not have enough bandwidth for lossless and you need a WiFi network to do that.

So the only lossless ones I'm aware of are proprietary systems like B&Ws new Formation stuff which is expensive, and Apple's Airplay which is in few speakers so far. Formation also can act as a Roon endpoint so you could use that lovely interface to pick your music.

Another issue to watch for is that powered speakers are mostly smaller, and folks think "oh I'll add a subwoofer" but most of those do not have any provision to add a subwoofer properly. By "properly" I mean that somewhere there must be a highpass filter cutting the bass out of the satellites, so their amp and woofer are not still straining uselessly to reproduce the low notes, obviating a lot of the benefit of the sub. Even if something has a "subwoofer out" you have to do detailed research as to whether there is a highpass setting.

"there is usually a transmitter"... Does the speaker manufacturer supply that transmitter? And, head_unit, for bluetooth I would have to get a bluetooth transmitter for my amp (or preamp), right?

I’ve never seen a wireless speaker that included a transmitter. Most wireless speakers are Bluetooth based, which means the phone etc. transmits to it.

Some AVR manufacturers such as Denon and Yamaha are beginning to provide wireless surrounds, as long as you use their speakers.

If your AVR has preamp outputs, you can add a transmitter / receiver system to send to an amplifier at the back of the room that the surround speakers would connect to.
