See the photos provided. Here are a few tips to make the installation easy.INSTALLATION TIPS1) use a small hook tool to remove the speaker grills, not a nail2) use painter's tape to hold the cut-out template to the ceiling; don't use the worthless little sticky tabs provided3) cut out 2'x2' sheet foam squares to hold the insulation in place above the speakers and to prevent any insulation from getting into the speaker cone, which will vibrate and drive you crazy4) pre-tap the screws before putting the speaker in place. This helps prevent stripping the phillips screw heads when screwing the speaker clamps in place5) use a *slightly* damp cloth to wipe dusty finger prints from the speaker cone and ring. be gentle.SPEAKER PROs* inexpensive but not 'cheap'. There's a difference.* they sound decent, maybe a tad mid-high heavy, but the mid-bass frequencies are balanced and clear* can't beat the price for performance factor* easy install - I installed 6 speakers in 4 hours, including set-up, tear-down and clean-up.SPEAKER CONs* they sound decent, maybe a tad mid-high heavy, but the mid-bass frequencies are balanced* they are power-hungry. be sure to use an amp around 75-100 watts. Under-powering these speakers will make them sound faint and will not give the bass, mids and trebles 'punch'.MY THOUGHTSKeep in mind these are in-ceiling/in-wall speakers and unless you encapsulate them in sound boxes (like in-wall speaker cabinets) that are perfectly tuned to the cubic volume to maximize the sound, you will get decent but not 'wow' factor sound. Most installations will be with insulation behind the speaker magnets, which absorb bass reflex sound, which is what my installation was. Despite not giving the speakers a good encapsulated and ported environment, they still sound surprisngly good.If I were to use these for theatre surround sound, I would build ported boxes behind each in the wall or ceiling, acting like a speaker cabinet. Although, surround sound speakers don't do a lot of sound work during movies and live programming, so installing these as true surround sound speakers, I don't think a built-in speaker box is necessary. If these were installed as primary sound driver, yes, I would install speaker boxes behind them.MY REFERENCE POINTS to judge the performance and sound of the MICCA M-8C* I use Sonos products to wirelessly connect the entire home, controlled by the Sonos app on my phone* I have a Sonos Arc, Sonos Sub and two Sonos Ones in our family room.* I have a 9.1 Mirage home theatre system in our media room. (two 5' towers, one center channel, six ceiling mounted surround speakers and one 12" subwoofer). It is powered by a Pioneer SC-61 amp. I use a Sonos Port to connect the home theatre system to the whole house sound solution.* I have two Polk Audio Atrium 6 speakers on the back deck, connected to a Sonos Amp inside, which also powers two of the six Micca in-ceiling speakers, located in our dining room.* I have two Polk Audio Atrium 4 speakers and two 10" passive Synergistic towers in the garage, powered by an old Denon stereo amp. Who doesn't like to listen to the game or rockin' music when working in the garage?* I use a Sonos Amp to power the remaining four Micca in-ceiling speakers in our downstairs bar area.* I have 17 guitars, 6 guitar amps and a plethora of sound gear.I share all this to suggest I have been around 'sound' for a long, long time. There's nothing like a well-mixed live sound, which is my ultimate reference for designing my whole-house sound solution. While I am not an expert, I do like clear, crisp, clean unmuddled sound and I think for the price and for the intended purpose (in-ceiling), the Micca speakers do the trick. I couldn't justify spending $500 on two Bose in-ceiling speakers, for example.
