    Should I use this OR the newly-released Alpha In Wall Surround Speaker Dual 5.25 Inch Carbon Fiber 2-way Vari-Angled (Product # 13687)? I can't decide between these two for my front speakers as part of a 5.1 home theater setup.

    I live in a small apartment (1,066 sq ft) and the living room is rectangular in shaped, I am just not sure if angled front speakers work better here.

    Thank you in advance.

    Are there rough in boxes available for these speakers? Are there rough in boxes for ANY of Monoprice's in wall speakers?
    Christopher H on Jan 24, 2017
    BEST ANSWER: Thank you for you question. There are some enclosures we offer but they will be only for specific in-ceiling speakers that we offer. We would not carry any rough in boxes for our in-wall speakers. I do apologize for any inconvenience.
    Will these fit in a standard wall with 2x4s? It appears the depth is 6", but not sure.
    Merrick M on Dec 14, 2016
    BEST ANSWER: no they will not, they are too deep to fit in a normal wall cavity that is framed with 2x4s. I have a rear wall with 2x4 framing and drywall on each side. I believe the mounting depth is 5.5" from what I recall. I used 1X4s to create a picture frame around each speaker, basically a rectangle of 1x4 mounted over another rectangle of 1x4 to mount these. A 1x4 is .75" deep, so doubled up it added 1.5" to an existing 3.5" cavity taken up by the 2x4 giving 5" plus the thickness of drywall so I had plenty of depth to mount them. If you are planing on cutting a hole in the drywall and mounting these they will not work but if you can build a simple frame and attach it to studs then allow the speaker to mount to the frame it will.
    Do these speakers include an enclosure, or do I need to provide one?
    peter t on Apr 3, 2017
    BEST ANSWER: They do not do not come with any sort of enclosure. Monoprice sells a two different types of enclosures if you would like one, but I actually don't know if they will fit this model speaker due to size. I would research the reviews o of the enclosures or confirm with Monoprice before buying the enclosures for certain speakers, as I recall in some reviews that they don't fit all speaker models although the sizes seem compatible.
    What is the minimum width between joists if installing these in the ceiling (on their long edge)? In other words, what is the width of the black part of the enclosure that extends up into the ceiling? I see a cutout dimension of 13.77" x 9.75" x 6.00"... Is is safe to assume I need 14" clear between joists, and 6" of height?
    Owen B on Feb 6, 2018
    BEST ANSWER: Yes 14" is enough space.
    Looking at these for rear surrounds in the ceiling, I have a drop ceiling so would I need to building bracing for these? Also rating the sound quality would the be suitable rear surrounds??
    A shopper on Sep 23, 2018
    BEST ANSWER: I do have suspended ceiling w/ 2ft squares, however, it isn't really a drop. It is attached directly the the bottom of the joist. So my biggest issue was fitting these into the cavity between the joists, so mine are attached to the joists, not the suspended ceiling. However, in your case, I think they are light enough it may be possible to use 2ftx2ftx3/8in plywood (painted white). However, that might cause too much vibration of they aren't better supported. I would attach the plywood with 2x4 to the joist.

    Also because mine were in a tighter space, I had to experiment with the how tightly packed the soundproof insulation (rockwool) was around the speaker to find a balance between sound quality downstairs and not hearing them through the floor upstairs. Sorry I can't directly answer your question because my situation isn't exactly the same. I would by one and experiment before buying the rest. Also, I got all of mine with a 40% coupon.
    can you install this speaker in the ceiling?
    A shopper on Nov 27, 2016
    BEST ANSWER: Exactly where I installed mine and I couldn't be happier with my center channel. Much easier installing in the ceiling than in the wall.
    My ceiling is angled (30 degrees?) towards the TV, so front speakers are facing away from viewer - Would these be a viable option (tweeter aimed back towards viewer) for Front LR mains AND rear surrounds paired with the adjustable alpha dual center? Wall mounted speakers are not an option. Thank you!

    Monoprice Caliber Ceiling Speakers 6.5in Fiber 3-Way with Concentric Mid/Highs (pair)
    BEST ANSWER: I have both of those the wall and the ceiling speakers. The ceiling speakers (6.5" PN#7605) should actually work pretty well in your situation. If installed with the tweeter at the top, it would probably face almost straight down. You just have to know these speakers are 13" in diameter, and are larger than they may appear in photos.
    Are the grills on this speaker magnetic? Some reviews say they are not despite speaker description saying that they are magnetic.
    Joe H on Dec 11, 2017
    BEST ANSWER: Not magnetic, but installed smoothly without any issues.
    Is this good to use for Left, Center, and Right?
    Andrew K on Feb 19, 2017
    BEST ANSWER: Hey Andrew...I bought this same speaker to use only for my center. The reason I chose this speaker for my center is due to the limited room that I had under or above my 70" TV. The only option I had was to go with a ceiling mount speaker above the TV. The best option this speaker offers is the way it can adjust 24 degrees in order to find the sweet spot in the main listening position. I would highly recommend this speaker for a center option if you're limited on mounting options. As far as the left and right goes, you could possibly use this speaker for a Dolby Atmos set up and aim the speakers toward the ceiling so that the sound seems to give you that raining down effect that Atmos seems to create. Other than that, i would look at other options for your left and right speakers...depending on your mounting capabilities. Hope this helps ya...
    I'm planning to install the 7.2.4 atmos set up. The LCR will be these speakers. I haven't decided on the in-ceiling speakers yet but might be the 13687 model below. The new speakers that will be releasing in October, will the line up include a single 5.25" or 6.5" with the ribbon tweeter? The current 8" would be an overkill for the setup. And is October still the correct release date?

    Thanks in advance.

    BEST ANSWER: The alphas are also great speakers. The new Ambers are still slated for Oct. Ceiling mount versions will be available in 6.5 and 8 inch.
    Should I use this newly-released Alpha In Wall Surround Speaker Dual 5.25 Inch Carbon Fiber 2-way Vari-Angled or the Alpha In Wall Speakers 8 Inch Carbon Fiber 2-way (Product # 13682)? I can't decide between these two for my front speakers as part of a 5.1 home theater setup.

    Sound great, fit right between ceiling joists
    I needed ceiling speakers for surrounds in a 7,2 system, but had no wall space. I wanted angled speakers but needed better response and more precise aiming. These worked perfectly and as it turned out, fit exactly between the ceiling joists. I put fabric back hats on them from Parts Express so insulation didn't fill the woofers with fiberglass. Other than that, and painting the frills to match the ceiling color, that was it. I adjusted the speaker angle and set up the rest of the system. They work and sound great.

    Couldn't be happier-just what I needed
    Using this as an in-ceiling center channel, 2ft in front of the screen, 8ft from audience. Angled at 45degrees to the listener. Driving with a Onkyo 656 receiver with no issues. Sounds fantastic as my center channel! Crystal clear. Contrary to popular opinion the direction of the sound is not an issue and does not seem like it's coming from the ceiling. I did not have the option to mount in the wall, thus I am very happy that Monoprice offered this directional speaker.

    Decent Speakers, Misleading Info
    I've had these speakers for a week now, and have been using them for music and movies. So far, no complaints about the sound -- They sound fantastic for $50 speakers.

    The only complaint I have is that the description claims they come with a magnetic grill; They do not. This is disappointing because the rest of the speakers in this line come with magnetic grills, and these will not match the rest of my speakers.

    It's not a huge complaint (these will be front LR speakers in the ceiling), so it will barely be noticeable. And with the sound being as satisfactory as it is, I am ultimately happy with the purchase.

    Exceeded my expectations!
    wall real-estate was an issue for me, and with little kids in the house, I couldn't have any floor stand speakers. After installing these speakers I couldn't believe how good they sound! I highly recommend these!

    Bought this speaker for my center channel in my 7.2 surround set up and it sounds great. They are also easy to install

    So I set this speaker up as a central one, right above the TV, in the ceiling. Let me tell you...its sounds great! Worth the money, will not be disappointed. Just make sure you have a clearance to install, as I had half an inch between it and the upstairs insulation after installation...cutting it close.

    Amazing Center Speaker
    I used this for 2 ceiling mounted setups: 5.1 and 7.1 center channels. The quality and presence of sound is superb -far better than 95% of the speakers I have heard. This is a great buy.

    59 dollar speakers for real
    I got these about a week ago. Install was a little complicated to hook up the wire. It was also hard to hold the speaker to attach the speaker wire. Having said that. These sound open and airy for inwall speakers. They work great for my application where I had no choice but to do a ceiling mount center, The sound seems like it comes from the tv which is exactly what you want. I would recommend these to anyone who has a similar need. You will be impressed.

    Easy to install, Sounds great
    Using this for a center speaker in a basic 4 speaker living room system. Should be through break in period and is has clear crisp sound for the money. I'm using this with the Monoprice Caliber in ceiling 6.5 speakers as L/R(#7605) along with a Klipsch wireless sub. I will definitely consider this again when we start looking to setup our media room.
