This refers to short bursts of power, while root mean square (RMS) power handling indicates the amount of continuous power a device can sustain. Higher levels of distortion can also occur at peak power levels when the device is powered beyond its recommended usage.)
- Impedance: 8 ohms (Describes the resistance of an electric signal throughout the system. Devices with low impedance require less power to deliver optimal signals but are more at risk for damage from overloading. Higher impedance requires more power but is more protected from overload damage.)
- Minimum Frequency Response: 35 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Maximum Frequency Response: 0.03 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Sensitivity: 88 decibels
- High Resolution Audio: true (Hear music the way musicians and sound technicians intended it to be heard. Products that support hi-res audio deliver audio signals with a dynamic range and bandwidth far greater than that of a standard CD so you'll be able to enjoy pure music with outstanding sound quality. 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.)

Did not expect these speakers to sound so great!
I bought 2 of these speakers to use as in-wall surround speakers in a 5.1.4 setup. These speakers sound great as surround speakers, but sound even better when playing music. During parties I set my Denon AVR-x6700h to all channel stereo and these little speakers play loud and clear. I wanted to get the 6.5r speakers, but unfortunately they did not fit in the area I wanted them because of stud placement. I bought the 4.5R because that is all I could fit, but was very pleasantly surprised when I heard out good these little speakers sound! If you have the room for the 6.5" or 8.5" speakers, obviously get those, but if you can't fit a bigger speaker, these will not disappoint!

Yes, They disappear.
I bought these for overhead speakers for an Atmos set up. I didn't want to clutter up my ceiling with noticeable speakers and these were the smallest I could find. I wasn't loving the fact they aren't the same brand as the rest of my speakers but those would have been 2x as big. I didn't have the appetite for that, esp for basically sound effect speakers. Installed, they look tiny on the ceiling, but do not sound tinny. When sound is directed to them you can't even tell they are coming from the speaker. The sound is well distributed and matches my other speakers well enough.
