Revel C263 6.5 Inch 2-Way Aluminum In-Ceiling Speaker Review


We all like some form of entertainment. Movies are a great way to get away and get lost in a story. If you like movies, you probably have a home theater system at home, or are working on one. A critical part of it are the speakers.

There are multiple types of speakers. The most popular types are bookshelf, tower, and in-wall and in-ceiling. When you are designing your speaker system, a big part to consider is the WAF, or Wife Acceptance Factor. You typically get the best sound from bookshelf or tower speakers. But if you are married, your wife may not like all of those speakers hanging on the walls, or just being visible. Hence, the WAF. This is where in-wall or in-ceiling speakers come in. You don’t notice them.

In-wall or in-ceiling speakers are great for the WAF factor. But with the newer Dolby Atmos or DTS:X surround sound formats, there is now height channels to consider in your surround sound design. There are multiple speaker designs for this new height channel speakers. But the best one is adding a set of in-ceiling speakers. So whether you are looking because of the WAF factor, or you are upgrading an existing system for the new surround sound format, you could be in the market for some in-ceiling speakers. Enter the Revel C263 6.5 inch 2-way in-ceiling speaker.

The Revel C263 came in a standard brown box. Opening the box revealed a very well protected speaker held in place by custom molded cardboard. Materials used in the construction was metal and plastic. Quality of materials used was excellent, as was the fit and finish. It is a very well made speaker. As an in-ceiling speaker, it also includes the crossover network, which is built-into the housing. The crossover network components: The coils, caps, etc are metal with some plastic. The speaker housing is plastic. The speaker itself is a 2-way design, with a tweeter and woofer. The tweeter is 1 inch and woofer is 6.5 inch and both are aluminum. And everything was put together very well and was of excellent quality.


In designing a speaker system, there is voicing to consider. If you are adding to an existing speaker system, such as adding height speakers to upgrade to a Dolby Atmos system, you will want to keep voicing in mind. This means you will want to get new speakers that will sound similar to your existing speakers. That way, when you are watching a movie and you hear the surround sound effects moving from speaker to speaker, it isn’t audibly noticeable when sound goes from one speaker to another. Revel offers models where the drivers are aluminum and micro-ceramic composite, so when given the opportunity to review Revel’s in-ceiling speakers, we went with the Revel C263. Having an aluminum wooer, it would voice more similar to the NHT Classic Three speakers in our reference room, which uses aluminum drivers.


Also included in the box was the owner’s manual, speaker cut –out, and magnetically held in place metal speaker grill. The instructions were very easy to follow. This made for a very simple installation. There were four extremely long screws that went from the front to the back of the speaker housing. At the back of the housing were four legs that these screws went into. As you tightened the screws, it moved the legs, or anchors, towards the front of the speakers housing until it hit the drywall. Tightening the screw tightened the anchor up against the drywall and held the speaker firmly in place. And magnets built into the housing held the speaker grill in place on the front. Speaker wire connections were simple spring loaded terminals which held the speaker wires in place. Now that they are installed and wired, let’s hear how they sound.


To test how they sound I first turned to movies. I went to a couple of my favorite movies: R.E.D. and Ready Player One. Explosions and mayhem are great for testing speakers, but so is a lot of surround sound activity, to test speaker integration with the rest of the system. And then music is also a great way to test sound quality and resolution.  So for music I turned to: Christina Perri: 1000 Years, and Adele: Rolling in the Deep. In the listening tests I was looking for speaker integration as well as sound quality.


I was very impressed with the speaker integration. Voicing was actually very good. The Revel C263’s using aluminum with both drivers was a good match for my reference NHT Classic Three’s. The voicing was not perfect, but it was as good as I was hoping. And the difference was not very noticeable, unless you stopped and really listened for it. They also did not have the dynamics, resolution, or low end extension and output as the NHT Classic Three’s. But for in-ceiling speakers at their price point, they sounded much better than I was expecting! With this kind of sound, Revel has a welcoming home in my theater room.


Listening to music, I first turned to Christina Perri: 1000 Years. Piano sounded very natural with very good harmonics. Owning a baby grand, and being around piano my whole life, I tend to be extremely critical of piano. The Revels did a very good job. Guitar sounded really crisp and clean with better than expected resolution of the strings and pitch definition. The same was true of the violin. Vocals were also very good with a smooth texture that provided very good resolution of the timbre and harmonics. Drums also had good impact and played with good extension and authority.


Next up was Adele: Rolling in the Deep. Guitar was crisp and clean with very good resolution of the strings. Kick drum had good impact, low end extension, and played with sufficient authority and dynamics. High hat and cymbals were also really crisp and detailed. Piano was also very natural sounding with nice harmonics. And Adele’s vocals came out with excellent texture and timbre.

For movies, I first turned to one of my favorite: Ready Player One. The race scene at the beginning of the movie is one of the best. There’s a lot of mayhem as cars are racing, whizzing and crashing all around you. And then there are all of the coins from the crashed cars as they get collected. King Kong running around the screen and across the speakers is also really cool.  The Revel C263’s did a great job in turning all of that mayhem into realistic sound that gets you caught up in the movie.


The next movie I turned to was R.E.D. One of my favorite scenes is the stand-off scene between the old man Marvin played by John Malkovich and the lady CIA Agent, with his 460 S&W Magnum vs. her RPG. On that action scene, there’s great surround sound effects as there are bullets flying all around you. There’s explosions from grenades. And then the awesome scene with the great shot of his bullet exploding the RPG in mid air. The speakers were dynamic and did a great job!

 
I was more impressed with the Revel C263’s, as Revel’s entry level in-ceiling speaker for only $175 MSRP. They provided great sound, especially for their price point. Even when really pushed at high volumes they sounded great without strain. If you are in the market for some in-ceiling speakers, the Revel C263 should be on your short list. Based on their design, features, quality and performance, the Revel C263 has earned our Highly Recommended Award. For more info and complete specs, check out their website at www.revelspeakers.com. Reference gear used: Onkyo TX-RZ920 receiver, Emotiva BasX A-500 5 channel amplifier, Oppo Digital BDP-103D transport, NHT Classic Three and Classic Three C speaker system, and SVS PC Plus 16-46 subwoofer.

Emotiva BasX A-500 5 Channel Home Theater Amp Review


We’ve come a long way since the beginning of Dolby with Dolby Stereo. The sound keeps getting better, not just in the number of channels, but also the quality of the sound as well. We now have easy access to 11 channels for full surround sound envelopment with Dolby Atmos and DTS:X. And modern surround sound receivers also allow use of discrete separate amps for better sound. So whether you want to improve the sound of your 5.1 of 7.1 surround sound, or you want to upgrade to the latest 7.1.4 of Dolby Atmos or DTS:X, you will probably need a separate amp. Enter the Emotiva BasX A-500.

The Emotiva BasX A-500 came double boxed in a standard brown cardboard box. Opening the box revealed a well protected amp, held securely in place by custom molded Styrofoam, and wrapped in a black cloth bag. Pulling out and unwrapping the amp revealed a very well made product. Materials used in the construction were almost all metal, with a very high quality brushed black aluminum face plate. Quality of materials used was also excellent, as was fit and finish. The Emotive BasX is a very well made product and it shows. Taking off the cover plate showed high quality internal components, with tight connections. Connections on the back were also very good. I was amazed at the quality for only $499, and starting to get very excited to hear how it sounds. Also included in the box was the power cord, remote turn on cable, owner’s manual, and a couple spare fuses. 


 Setting up the amp in my rack was very simple. It was just a matter of connection the RCA line outs on the receiver to the line ins on the back of the amp. Then connecting the remote out of the receiver to the remote in on the amp, and then plugging it in. Having a Dolby Atmos or DTS:X 7.1.4 system in our reference room, we will be able to test the Emotiva BasX A-500 for both scenarios.



Our reference receiver is the Onkyo TX-RZ920, which has an internal THX amp rated at 135 watts, 2 channels driven at 1 kHz. The Emotiva BasX A-500 is rated at 110 watts a channel, but is rated at 20-20000 Hz. The power output should be fairly close for both the Onkyo and Emotiva, even though the rated output is a little different. This should be a fairly good apples to apples comparison. That way we can tell how the Emotiva BasX A-500 compares to an internal receiver amp. And then we’ll test how well it does as an upgrade add-on for Dolby Atmos or DTS:X. Now that it’s all connected, let’s hear how it sounds.

I started off with measurements from my sound meter, and measured during a few clips of a couple of my favorite movies: RED and Ready Player One. Reference gear used was an Onkyo TX-RZ920 THX Receiver, Oppo Digital BDP-103D transport, NHT Classic Three’s and NHT Classic Three C, in a 5.1 system and SVS 16-46 PC Plus as the subwoofer. I first measured using just the internal amp at a set volume level on the receiver. I took measurement readings for peak volume during a few clips for each movie. After I was done measuring the several clips in both movies, I hooked up the Emotiva BasX A-500. I went through the same clips of each movie, listening to each clip a few times and noting the peak volume of each clip at center listening position. The measurements came out really close, as I expected. Through out all of the clips, there was only a 1db difference in volume at the same output level, and it was the Emotiva amp that had the lower volume output. But that could be due to the slight signal loss going from the receiver to the amp through the RCA’s. But again, the difference is minimal, barely noticeable if you are listening for it and doing an AB test the way I was. Now let’s see how they actually sound. 


I was impressed with the sound of the internal amp of the Onkyo TX-RZ920. In fairly recent years, Onkyo made the jump to using a digital amp.  While it’s a digital Class D topology, it still has a very good neutral sound. For those who don’t want more, it’s a good amp. And is even THX certified.


If you want to get the best performance out of your home theater, getting a dedicated amp is the way to go. The Emotive BasX A-500 is a great economical way to do it! With an MSRP of only $499, it’s a steal! As stated previously, the output in volume is just a hair under the output of the internal amp at the same volume level of the receiver. But that’s just part of the story. There is a lot more head room with the Emotiva.


Listening to the Emotiva BasX A-500, I heard the same neutral sound as the internal amp, but there was also a lot more. Music had more clarity and resolution. The midbass was fuller with more punch. Dynamics in movies was also greater. The difference was not huge, but it was there and noticeable. And in cranking up the volume to much louder than I listen to, it was still really clean, with crisp highs, smooth mids, very articulate vocals, and tight punchy midbass.  Transparency level from the amp was also very good!  And not only that, but it sounded just really full, with plenty of reserves still on tap.


It’s kind of like the analogy I like to use with engines, and horse power and torque. You can get a big horsepower engine without a lot of torque. And while it’ll have power in the horsepower, with a lack of torque it’s lacking muscle behind it. So while the internal amp sounds good and will play loud, it doesn’t have the reserves or muscle behind it like you get with and engine that has a lot of torque. You won’t have the same full sound or the perceived headroom behind it so it won’t sound a tad thin. You can definitely tell using the Emotiva as dedicated amp gives you a lot of brawn on tap.


The Emotiva BasX is an outstanding dedicated theater room Amp. If you’re happy with the performance of your internal amp, but want to make the jump to Dolby Atmos, or DTS:X, the Emotiva BasX A-500 is a great add-on amp to power the 4 height channels. And given the close output levels as previously discussed, it’s also a great match to the internal amp, when used to power the height channels, as they are both close to the same wattages.

 Using the Emotiva BasX as an add-on amp to power 4 height channel speakers proved to be an excellent fit. Getting it all wired up, and running the calibration software, it was now time to test the amp with Dolby Atmos in 5.1.4. As Darth Vader said to Luke, “Impressive, most impressive.” The Emotiva BasX A-500 made my Revel C263’s really sing! Highs were crisp and clean, mids were very smooth and bass had good extension and punch in the midbass. There was plenty of power on tap for the Revels, and the sound provided with Dolby Atmos was holographic, fully enveloping you in all of the action!

 In the end, the Emotiva BasX A-500 provides a real synergy! It provides an excellent build quality for a product that will provide years of use. But it sounds just as good, giving a performance that is more than the sum of the parts. It’s not perfect, but given its low MSRP of only $499, it’s bang for the buck is off the charts! And it provides a lot of functionality. If you’re looking to up your game in your home theater setup, the Emotiva BasX A-500 should be on your short list. But I do have a word of caution.  If you are using your surround sound receiver to power your mains and get a BasX amp for the height channels, don’t try out the BasX on your mains.  If you do, you may just end up keeping it there and getting another BasX for the height channels! Like a BasX A-700 for the mains and a A-500 for the heights in a 7.1.4 setup. Based on its design, features, quality and performance, the Emotiva BasX A-500 has earned our Editor’s Choice Award.
