Praise for the MartinLogan Crescendo wireless music system from Sound & Vision

If you're looking for a flexible solution for high-quality casual listening and aren't worried about an expansive soundstage, the Crescendo delivers the goods. It doesn't come cheap, but you have to remember you're also getting a work of art that you'll be proud to display. "

Room-filling sound and expandability

At the heart of the Crescendo sits a front-firing 5" x 7" polypropylene cone woofer housed in its own ported chamber, which gives the driver room to move and breathe. You'll enjoy deep bass and accurate midrange. The woofer and the two adjacent Folded Motion™ tweeters each have their own dedicated Class D amplifier for 100 watts of total power. The drivers are housed in a sturdy MDF enclosure that resists sound-muddying vibrations, finished in your choice of piano black or real wood veneer. While the Crescendo provides substantial bass for what we traditionally expect from a one-piece system, MartinLogan knows there are situations that call for more. A subwoofer output lets you connect a separate powered sub (not included), for those times when you really need more boom.

Folded Motion Tweeter

MartinLogan's innovative Folded Motion tweeters result in quicker response and lower distortion.

Detail and precision from the Folded Motion tweeters

MartinLogan's innovative Folded Motion tweeters are found on either side of the woofer. Each tweeter uses a pleated diaphragm that works like an accordion by "squeezing" air to create sound. It requires about 90% less excursion than a typical dome tweeter, resulting in quicker response time and much lower distortion. You'll experience crystal-clear high frequencies with lifelike dynamics. The tweeters are angled outward to provide a wider soundstage. Proper stereo separation like this is simply not typical in one-piece systems. Music sounds intricately detailed, but smooth and effortless, without a trace of harshness.

Folding Ribbon Goodness

Guest from North Carolina on 1/28/2018

Verified employee purchase (What's this?)

Love at first listen? Nope. These tweeters need up to 70 hours to break in properly. I have about 25 hours in and the detail is starting to present itself. The unit has a sub out feature which I am playing with. Using a old 8" small but musical miller and kreisel sub in a 16x20 room. Not sure it "Needs it" but It certainly adds a fuller soundstage. This is for a master bedroom. In my home I have 2 home theatre systems and Two fine 2.0 set ups. I mention this because my purpose for this unit was not to be overly ambitious but purchase a fine looking piece that is a pleasure look at and sounds great. Easy operation was also a priority. This is integrated with home music server (hardwired) but I also wanted Bluetooth and use it as a soundbar from the TV on occasion. I have the Walnut finish and super happy with the fit and finish. As for the sound I encourage you to seek out reviews on the internet form journalists whose job it is to review and have critical ears. I am very impressed with the detail with and without the sub provides especially at lower volume! The unit falls within a "lifestyle" category of electronics. It not only functions to provide a great sound but does so with a graceful elegance!

Pros: Sound detail, bass, ease of operation

Cons: Premium products carry a premium price

Great Martin Logan Sound

Pigeonhed from North Carolina on 11/12/2015

Verified customer (What's this?)
Verified employee purchase (What's this?)

My Father-in-Law wanted a simple solution for his home theater system to be used in a small room and he asked my advice. When I asked him what he was considering, he told me a Bose Wave system. Up until a few years ago, I had been a life long Bose fan (and I still love my 901s). But I had purchased several Martin Logan speakers from the Motion series about 18 months ago and realized that they have a sound that Bose just can't recreate when you are listening to newer recordings, so I recommended the Crescendo. Since my Father-in-Law lives in South America, I had the Crescendo delivered to my house. And of course, I had to take it for a week long test drive. The sound is premium Martin Logan. Warm and real, with a great clarity. I also purchased the Martin Logan Dynamo 300 sub to fill out the lower frequencies, so this little, unassuming system really did the job. I was extremely impressed. I have to admit that without the Dynamo 300, the Crescendo would sound a little flat (obviously), but I naturally compared this set up to my system that has a 1000w sub and costs seven times more. For the price, you really cannot ask for a better sound, especially if your goal is to have a great sounding set up with a small foot print. The crescendo sounded outstanding even when standing in another room. Everything from Steely Dan to Damian Erskine to dub step was solidly represented. I will add, just like my Motions, there is a break in period to get the best sound.

Pros: Warm Matin Logan sound for a reasonable price, in a portable configuration.

Cons: This system (in my opinion) really needs the Dynamo 300 to Truly seal the deal musically, but you can pick up a 300 for a steal. The cost for this configuration is comparable to many other similar systems at this price point without the sub, but it will have None of the deeper bass note compromises a system this small will always fail to accurately reproduce. That matters to me, but maybe that doesn't bother most people.

Oh well

Always been a M-L fan. Aspirational for their electro-statics. The piece is beautiful furniture, sounds as though someone sat on it. Zero high end while streaming blue tooth from Spotify, on their maximum bit rate. Direct plug in didn't help. Bass is breathy, and boomy. Perhaps this was a defective unit. Wanted a high end, good sounding, wireless streaming speaker, this is not it. The return was graciously accepted..

Pros: Pretty

Cons: Sounds like an AM radio form the 60's

Best High End Blue Tooth Speaker

AZ Ed from Tucson, AZ on 12/11/2014

Verified customer (What's this?)
Verified employee purchase (What's this?)

The speaker appearance sets it apart from the standard square or round designed speaker. The instructions and packaging are outstanding. The speaker looks understated, but over performs in connectivity and musicality. I used my iPhone 6 to run music through USB, airplay and bluetooth. They all worked flawlessly. The equalization of the music was nearly spot on and pushing the speaker to it's top volume produced the same clear and undistorted sound output. I'm thinking about adding a subwoofer later to see just how much more amazing this speaker can be. This was a huge upgrade/change from my current Bose Soundesign speaker I use in the office.

Pros: Appearance, Finish, Outstanding music reproduction, Zero Distortion at Max Volume, Connectivity

Cons: Size is a bit large Input jacks in the front would have been more useful

Best small wireless solution so far

Douglas from San Francisco, CA on 4/10/2014

Verified customer (What's this?)
Verified employee purchase (What's this?)

This is a great product. Bought it from Crutchfield. First impressions: build quality is outstanding, very stylish and well packed. Remote is of very high quality as well. Hook up was very simple, although instruction booklet was not that helpful. Sound: I was blown away by the quality of the tweeters, really transparent and natural sounding for such a small and cheap speaker. It will outclass B&W and Bang&Olufsen by a mile. Midbass was more of what you would expect from a small speaker, although the single midbass driver seems as a clever solution. Tried different sources, by far the best was the ipod directly connected to the equipment via USB and using lossless files. The wireless Airplay or bluetooth seems to lower the quality. Bottom line: hands down the best small wireless speaker I've heard.

Pros: Transparency of highs Connectivity Subwoofer output Build Quality

Cons: Slight unbalance between highs and midbass sound quality. Highs are really really good while midbass is not at the same level

More details on the MartinLogan Crescendo

Stacey B.

Product Research


Built-in Class-D Amp w/ Advanced DSP: At the core of the MartinLogan Crescendo is an advanced 24-bit/48kHz DSP (digital signal processing) based preamplifier in conjunction with a powerful class-D closed-loop 100-watt (140-watt peak) amplifier. Crescendo's digital amplifier produces sound with accuracy, resolution, and, detail. 50 watts x 1 channel is delivered to the 5"x7" cone woofer and 25 watts x 2 channel is delivered to the dual 1" Folded Motion tweeters.

Two-Way Driver Design: The MartinLogan Crescendo premium wireless speaker system create creates a powerfully detailed sound from its two 1" Folded Motion tweeters and one 5"x7" polypropylene woofer for a room-filling experience. Low and High frequencies are seamlessly blended together between the drivers for a natural sound.

  • Two 1" Folded Motion Tweeters: The signature Folded Motion tweeters utilize extremely low mass diaphragms that "squeeze" air, and require significantly less excursion than the typical 1" dome tweeter, which drastically minimizes distortion while providing a lightning fast response time. The increased surface area also provides a wide, yet controlled sound dispersion to create a realistic and carefully etched sound stage.
  • 5"x7" Polypropylene Woofer: The custom designed front-firing 5x7-inch matte black polypropylene cone woofer features an extended throw drive assembly in a non-resonant asymmetrical chamber format for deep, accurate bass.

Solid MDF Enclosure: The MartinLogan Crescendo is crafted with a solid MDF enclosure that strengthens and intensifies low-frequency bass performance while minimizing vibrations. The dense cabinet enclosure, wrapped in either high-gloss piano black paint or real-wood walnut veneer, floats atop a sturdy aluminum stand and looks comfortably at home in any décor where aesthetics are as important as sound quality. Designed to fit a modern décor, MartinLogan utilizes high-quality materials and finishes to give Crescendo a furniture and artwork like appearance.

Network Connection (Wired or Wireless): The Crescendo is equipped with dual network connection methods. There's an RJ-45 LAN (Ethernet) port for direct wired connection to your home network, and there's also the built-in WiFi feature that includes WiFi Protected Setup for safe and secure connection to your wireless home network.

  • Audio Streaming: You will be able to wirelessly stream stored music and music apps from your Bluetooth-enabled device to the Crescendo wireless speaker system. Playback functions, music navigation, and song/artist information will still need to be handled from your Bluetooth-enable device.
  • apt-X Code: The MartinLogan Crescendo employs apt-X audio coding technology for lossless, CD-quality streaming with apt-X compatible smartphones (like some Androids).

Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the wireless speaker system.

Aux Input (Digital or Analog): The unit's Aux Input can be used as either a digital optical (Toslink) or analog input. This input will accept either a standard 3.5mm stereo headphone style or mini-Toslink plug. A special mini-Toslink to Toslink cable or mini-Toslink adaptor is required for digital optical connection.

In addition, front-mounted control panel allows quick access to power, input and volume controls.
