    I have recently purchased several pairs of these speakers (4929). I have not found back covers available for purchase. I'd like to try to design one myself and 3D Print on my printer. This is an unusual request but because of the build quality and component fit I'm sure the manufacture must have designed using 3D CAD files. Please could you ask them to share 3D CAD format files? They can be reduced detail as many manufactures which to protect their IP. I'm not expecting that Monoprice would have these files but I'm asking you to please contact the manufacturer for this info.
    These are very well designed angled speaker. It makes my in-ceiling installation possible.
    Scott R on May 14, 2017
    BEST ANSWER: Great idea, this would greatly improve this product. Even if it was just the 3D CAD files of the white plastic housing (excluding the speaker and circuit card if necessary). I'd be happy to share my resulting 3d printer design files with your other customers.
    Thanks for you consideration.
    Can you aim the tweeter?
    William F on Mar 4, 2017
    BEST ANSWER: Thanks for your interest in this ceiling speaker. The tweeter does have 15° pivot ability.
    Can I obtain a new Cutout template and paint mask? Or, can someone tell me the exact diameter of the hole that needs to be cut?

    What is the difference between the 4104 and the 4929 speakers?

    Caliber In-Ceiling Speakers, 8in Fiber 2-Way (pair)
    BEST ANSWER: Both speakers will Mount flush in the ceiling, however the speakers that have a 15 degree offset will allow you to better construct a listening focal point and sound stage. If used in a surround sound application where all or most speakers are in ceiling, you can aim the speaker to your listening position to create a sweet spot for the sound, whereas the only adjustment on the other speakers is the tweeter angle.
    Is there a back enclosure sold by Monoprice for the 4929 speakers? I'm installing these in to new construction, with speaker already ran to speaker location, and would like to use a back enclosure for improved sound, as well as safety from the insulation. If there is not a back enclosure for the 4929, are there any concerns about sound, safety, and/or anything else?
    Todd P on Nov 21, 2017
    BEST ANSWER: I don't believe they make a back box for those. I have the back boxes on the regular 8" in ceiling speakers and they really don't make a difference in sound. If you are installing them in a ceiling with an attic, you will want to use a large vapor hat with them. You can buy them specifically for speakers or for pot lights. Or you can make your own with poly. If they are going in a basement or main floor ceiling, it's not necessary. The insulation won't hurt the speakers. The back boxes do help a bit with sound travel, but not much. Since it's new construction, you could build your own out of wood as well. If they are going in a basement or main floor ceiling, I highly recommend stuffing the joist cavity with Roxsul sound deadening insulation. Good luck and enjoy the speakers. I have them in my main floor theater and they perform very well. I have also used them for a lot of installations where the client was on a tight budget and never had one go bad.
    I have cathedral ceiling can 4929 work as surroun back? Between 4929 and black back speaker witch on is a better speaker?
    A shopper on Feb 18, 2018
    BEST ANSWER: Depends also on the size of the room. Also remember in ceiling speakers work best as height and atoms speakers they are not as efficient as regular speakers due to being off axis from where they are supposed to be placed traditionally. I also found that although they sound good they sometimes in surround and surround back situations struggled with high dynamic moments in the tweeter area. Too bright they'd distort Id recommend going up in price to they're ribbon tweeter series. And even though it's a bigger speaker use they're higher power model that have the 100 watt RMS 200 watt dynamic if you still want to use them as surround and surround backs
    Is anyone able to recommend a compatible rough-in bracket for the Caliber In-Ceiling Speakers, 8in Fiber 2-Way with 15° Angled Drivers (pair) (Product # 4929)?
    Anton Y on Jan 24, 2018
    BEST ANSWER: Hi I am not quite sure what you are asking, referring to a rough in bracket? I purchased these, cut a hole in the dry wall and turned the screws on the speakers , which holds them in place against the dry wall.
    Can these speakers be mounted in a suspended ceiling (acoustic tile)? If yes, is all hardware included to do so?
    A shopper on Sep 21, 2017
    BEST ANSWER: You could probably install them in a suspended ceiling with additional bracing. The speaker is quite weighty and may stress the limits of the ceiling tile and support cables if it is not already super sturdy. If you try it and succeed, it would be nice to see a follow up message.
    can one of these be used as a center channel speaker?
    Stephen R on May 26, 2017
    BEST ANSWER: The short answer is yes, but would not recommend it. A center channel is designed to be i a box that provides a good center channel sound. having said that I am using these speakers as the left/right surround sound speakers in a 7.2 setup, which work just as good as the B&W $250 a piece speaker.

    I am also using these as ceiling acoustic speakers for music, but still requires you to run a good sub-woofer.

    Would these speakers function better if I built a sealed enclosure behind them in the wall? If I cut into my ceiling and there is insulation/open attic above, will that affect performance?

    Well pleased with speakers
    [In wanting to provide as much information as possible, this review has become rather long.]

    Model 4929 "8 Inches Kevlar In-Ceiling Speakers (Pair) - w/ 15 Degree Angled Woofer"

    These are being used as rear surrounds in a 5.1 system).

    The pair of speakers is packaged in a single box, and is reasonably well packed. All the items listed in the specifications are indeed included.

    With the accessories is a strip of black "grill putty". The instructions do not give advice on where or how to use this, or why it might be needed. I found no use for it.

    For grill removal, the instructions state that the plastic frame can be twisted (carefully) to expose the grill edge. This is somewhat possible, but the frame is pretty rigid (a good thing) and would be impossible once the speakers are installed. It seems best to expose a little of the "side" of the grill, then use the grill removal tool to pull it in stages around the circumference. I experienced no deformation of the grill when doing this. By the way, there is a white, circular "dust cloth" inside the grill acoustically transparent, one hopes. Cosmetically, this dust cloth makes the speakers blend into a white ceiling even better.

    The speaker wire terminals are spring-loaded and seem to have a good "bite". While I would probably prefer screw terminals, these seem sufficiently robust. They will take 12-gage wire with no problem (I have Monoprice 2817). I would not recommend pin-type connectors (e.g., Monoprice 5975) since the pins are thin bare wire probably gives more contact than pins would.

    I fully agree with "Reviewer: Anonymous from Ortonville, MI 8/5/2010 11:36:36 AM" about pre-running the mounting screws before trying the installation. The only downside to doing this is that the tabs become quite a bit looser and could rotate outward when trying to put the speaker into its cutout to minimize this, just re-tighten slightly.

    The specifications state "Tweeter: 1" Pivoting Cat-Eye Silk Dome with Ferrofluid", but it is not obvious that it does indeed pivot. Certainly not a big deal since the entire speaker is angled. An email to Monoprice support yielded the answer that indeed it is adjustable...

    "Thank you for contacting us at Monoprice.com. In regards to your inquiry, I’d like to start by apologizing for the problem that you seem to be having with the Monoprice item. the pivoting tweeter does require force to move, the reason for that is if that was loose the vibration cause by the speaker when in use would cause the tweeter to freely move, with that being tight that prevents free movement."

    ...however, I haven't gotten the courage to really force it!

    The speakers will definitely need to have boxes around them if installed in a ceiling above which there is insulation - especially of the blown-in variety. I built 15-inch square by 6 3/4-inch high (outside dimensions) boxes from 3/4-inch MDF (15x15-inch top) and attached them to the top of the drywall ceiling with silicone caulk. In addition, I put two strips of 3/4-inch by 5/8-inch (thick) foam weather stripping on the side of a rafter and screwed the boxes to the rafter with the foam in between. (Installation easier said than done in my attic space with the blown-in insulation! I hate the stuff.)

    These are definitely ceiling-mount units for a couple of reasons. First, it would seem odd to use the angled speakers in a wall and second, the mounting depth is about 5 1/2-inches - more that most walls can handle.

    The circular template has no markings and actually has inner and outer perforated regions which are separated by about 3/16" (5mm) - which is about the thickness of the vertical part of the plastic frame at the ceiling interface. The inner (full) disk is the paint shield used to mask the inside of the speaker if painting the outer hole is the template used to lay out the circle for cutting the drywall. The diameter of the inner disk is about 10-1/16" (256mm) the outer is 10-7/16" (265mm). I dusted off geometric construction techniques from ancient memory and laid out the center as well as orthogonal diameters to aid in alignment for a circle cutter (see below).

    A basic drywall circle cutter is available for about $10 at places such as Home Depot or Lowe's. I made my own from a 3/4" thick by 1" wide by 24" long strip of wood by cutting a slot most of the length, drilling a hole for a nail (pivot), and trapping another nail (filed to a sharp edge) in the slot and using a machine screw and wingnut to provide the "squeeze". Loosen the wingnut and move the sharpened nail to set the radius using the supplied template (as marked above).

    Since I had determined the exact center of my boxes from the attic side, cutting the circles for the speakers was very easy using my home-made circle cutter. Once cut, I used the location of the dB "cut switch" to align the tilt with my walls and then extended the anchors all around. I chose not to use a power driver when running down the anchors so that I would have better feel for their tightness. I had no problem installing the speakers without help. WIth the grills back on the speakers, they are far less obvious than our "eyeball" recessed lighting fixtures.

    Once everything was connected, I ran my Denon 3808CI's Audyssey room correction with the result that all sounds great. The channel levels selected make the surrounds subtile, but quite noticably present. Listening to multi-channel SACDs is a pleasure, and movie sound tracks are quite enveloping. I'm sure I'll end up tinkering with the settings after the speakers have a few months of break-in time, but, right now, I'm quite pleased.

    I would not hesitate to recommend these speakers.

    PROS: Straightforward installation well-built good sound quality

    Great Speakers
    I purchased these speakers for my 5.0 surround home theater system and have been very pleased. I wanted to summarize my experience, because Ive learned so much from these threads.

    First of all, Im not an audiophile, but Ive got a 52 Samsung A550 and an Onkyo TX-SR606 Receiver and I wanted to improve on the Samsungs sound. The wall mounted TV is about 12 feet across the room from the couch, which is against the back wall, hence my decision to go with 5.1 vs 7.1.

    I decided to go with the 15-degree angled speakers, since they are all ceiling mounted and I wanted to direct the sound toward the listening area. Previously, I didn’t have any experience with ceiling speakers and I was a little nervous about how the sound would turn out, based on all I’d read on the web. I ran the Audyssey and think it’s done a great job with the surround sound. The back two speakers seem a little louder than the front three, but the overall effect is to “hear the sound in my head” rather than from the TV. It isn’t at all distracting and the sound is clearer to the point that I listen to the TV on lower volume than I did previously with the TV speakers.

    I’d seen a couple complaints about the speaker grills being difficult to remove. I’d agree with that assessment. I ran a paper clip into and out of the grill (see photo) and had two people pulling with pliers to remove the grill. The grill wasn’t damaged at all and goes back on pretty easily.

    Interestingly, the speaker instructions recommend 18-20 gauge wire. I use 14 gauge CL-2 in-wall wire from monoprice and had no problem at all. I wouldn’t have had trouble with 12 gauge either. The wires are red & black so it’s easy to keep track with the polarity, so I’d definitely recommend that as well. The speakers have a simple and effective way to attach the wires. Just push down on a button and that exposes a hole into which the wire is inserted. On black post in the photo you can see how large the hole is. Although my setup didn’t require it, I was able to easily twist two 14 gauge wires together and insert both into the hole. That would be handy if you need to wire a bunch of speakers in parallel. (Would you ever need to do that?)

    I also purchased the closed screw banana plugs and strongly recommend them. I had couple speakers wired backwards and swapping the wires on my receiver was a snap.

    The card board inserts were right on target for cutting holes in the ceiling. The speakers fit perfectly and the holes weren’t too big. The speaker rim has a 3/8 inch so that provides plenty of overlap giving the speakers a great look once the project was complete.

    The speakers mount to the drywall ceiling with four screws. The speakers feel pretty heavy when holding them up over your head and trying to tighten these screws. It’s definitely a two person job. After we installed the first three, I built a jig and it made installing the last two a piece of cake. I made the jig out of a 2x4 with a 1x4 nailed across the top to form a “T”. It’s much easier for someone to stand on the ground with this jig and hold the speaker in place while I tightened the 4 screws. (You can see the white drywall clip on the speaker in the photo with the speaker wire above.) This is my biggest “lesson learned” from the project.

    All-in-all, the speakers look great, sound great, and were easy to install. I would definitely go this route again and would recommend them.

    Solid speakers
    I was really impressed with the build quality of these speakers. and at the price, it's pretty hard to argue with what you get.

    Sound quality is on par with much more expensive speakers (of which I have several - including 2 pair of quite similar to these made by Omage, which cost me 5 times as much!)

    I paired these up with a set of the 6.5" 3-ways from Monoprice, and the sound is great. I do have a couple of suggestions, however:

    1. Build a box behind them. Speakers always sound better if they are in a box. Make sure the box is well sealed at the joints. The idea of a box is mostly about creating an air suspension behind the cone to control excessive movement, which will make your speakers distort less and avoid damaging the voicecoil. Inside the box, glue a little bit of insulation along one wall (usually the largest wall is best) to help control reflected soundwaves hitting the back of the speaker and knocking the cone around, which generates distortion.

    2. Even in a box, these speakers aren't going to provide the amount of bass most people will want in their living room or basement - nor should they. An 8" cone can only move so much air, regardless of the manufacturer of the speaker. Most people will want to pair up at least one subwoofer (size and quantity depends on room size, of course).

    3. Many modern receivers have adjustable crossover points for the outputs - take advantage of that, so the smaller speakers aren't getting hit with large amounts of low frequencies they can't adequately handle - then push all of those lows to your subwoofer. Your speakers will sound better all around if they're not trying to do jobs they're not capable of.

    The above tips apply to any in-wall speakers, no matter who makes them. They will sound excellent if you use them as they're intended above.

    Happy listening!

    PROS: - Easy installation
    - Good sound

    CONS: - Not really a con, but as with any smaller speaker like this, you will likely want to consider a subwoofer if you want warm lows. an 8" woofer doesn't cut it in all but the smallest rooms.

    look nice
    They were easy to install, are large and heavy which is good. hard to say how they sound because I'm using them for ceiling Dolby Atmos speakers. I can say they work ! LOL

    Spend the extra on better options
    For the money they are a good speaker. If you are using them as background sound in an office or commercial installation they are good and easy to install. Great wire terminals. if you are interested in great sound buy a better speaker. In wall speakers can cost 200-5000 each and the sound might still not be as good as an enclosed speaker. So overall for the price they are great. Comparing them to a 200 speaker they are weak. I still love mono price

    PROS: Look Great solid construction. Good For the price

    CONS: Too much mid. highs are muddy or not crisp

    Speakers don't sound very good
    I got these hoping to save some money on speakers for my master bathroom. The tweeters sound pretty good, but the mids sound horrible...The sound is actually so bad that subwoofer won't help. Basic drum beats, guitars, etc... were muted and I don't know how to describe it but the sound wasn't "real". The quality was so bad that I wouldn't even use these in high ceilings where I just want ambient sound. I will be returning these and going with others I have used in the past.

    PROS: Well constructed. Tweeters sound good.

    CONS: Mids sound really sub par

    Used four of them for my Mids and Rears in my home theater. Sound great and was impressed with quality of the speakers. One thing I would recommend to assure smooth installation is to pre-run the mounting screws through the mounting tab and then back out once before final installation. If this is not done, sometimes the tab can get twisted while the screw is trying to cut thru the plastic and doesn't allow the tab to seat correctly which can lead to a broken screw or tab. Found this out the hard way, but was easily rectified by the described procedure. Also allowed for easier installation when putting them in permanent location. Almost gave a 9 because of this but the sound and price trumped any minor installation learning curve.

    Great Dolby Atmos Ceiling Speakers
    Looks good. Easy install and they sound great. Appears to be excellent quality, solid construction. Nice connectors, not fiddly.

    PROS: Quality, solid construction, stout wire connectors

    CONS: Ceiling installs make my arms tired

    Excellent sound for the $$

    PROS: I have had speakers from Polk to Paradigm and was looking for an easy solution for my new basement remodel that required in-wall speakers. These rear speakers do a great job directing the sound and match well with my Paradigm fronts. I have a Denon 2807 powering all the speakers so these get plenty of power.

    CONS: I got them in the mail and had to wait to install them while the basement was finished :)
