Caliber In Ceiling Speakers 8 Inch Fiber 2-Way with 15° Angled Drivers (pair)
In-wall and in-ceiling speakers allow you to expand your listening environment throughout your entire home as well as remove the clutter of giant box speakers giving you back your living space. In either case it's a win-win situation for those who desire high fidelity and those who put emphasis on decor.
DuPont™ Kevlar® fiber cones are light weight yet extremely rigid, providing very precise audio with minimal distortion caused by cone flex. The Kevlar® woofers are matched with equally precise silk membrane dome tweeters made of titanium fiber thread and a high quality crossover network to ensure high fidelity and low distortion. The lower distortion levels allow the speaker to be driven harder and handle higher peak power levels. The main benefits of Kevlar® speakers are the clarity and fidelity at which they produce audio.
These aspeakers provide a 15 degree woofer configuration, which allow for more precise focusing of sounds, so you can custom tailor the sonic signature of your system.
- Light and rigid, well balanced, angled black woven Kevlar® cone eoofers for distortion free reproduction
- Oversized magnets for more impactful bass
- Precision ferrofluid cooled, cat-eye silk dome tweeters for sweeter highs and pure sonic clarity
- Pivoting tweeters allow you to point the accoustics to the prime listening position for a more accurate and immersive sonic experience
- Adjustable crossover switch allows you to match the speakers to the sonic characteristics of your listening environment and the location in which you place them
- 80W nomimal and 160W maximum power handling capacity ensures that these drivers won't be overdriven or easily blown out

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
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.

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.
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.
PROS: Look Great solid construction. Good For the price
CONS: Too much mid. highs are muddy or not crisp
PROS: Well constructed. Tweeters sound good.
CONS: Mids sound really sub par

Monoprice is my favorite web site !
PROS: this is my 2'nd order this month and both orders were over $650,00 This co. definitely,knows how to handle a business ,I live in London On. Canada and I place the order on Saturday oct 22'nd /2011 and Wednesday oct the 26'th /2011 I got it on the front door , and that was picking the cheapest ups rate..I mean those guys are good or those guys are GOOD..!! that's why I call them The best and the Fast..
About those 8"kevlar in ceiling speakers I was really amazed about the quality and sound , I just installed recently a Ht system for a customer and he was really impress with the look and the audio quality of those babies..easy to install and for the price ?? believe me you wont find speakers like this for $80.00 a pair ANYWERE period.
PROS: Quality, solid construction, stout wire connectors
CONS: Ceiling installs make my arms tired
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 :)
PROS: Great sound, easy install, look great.
