Mackie CR4BT Multimedia Monitors 50W with Bluetooth (Pair)

Compact and portable at 12 lb, this pair of 50W CR4BT Multimedia Monitors from Mackie provides audio playback in home and studio environments. As such, they are useful for mixing music or post-production sound, and they boast Bluetooth capability to boot.

The pair consists of one Class AB amplifier-powered monitor and a passive un-powered monitor that you can connect with an included stereo cable. For the low-end, these speakers utilize 4" polypropylene-coated woofers and a rear port tube, while the highs are handled by 0.75" silk dome tweeters; all of this ensures a frequency response of 70 to 20,000 Hz with a maximum SPL of 100 dB.

A switch allows you to select whether the powered speaker will function as the left or right monitor. This is particularly helpful when you must position the speakers near power outlets, or when you have to decide whether you'd rather have your front-panel volume knob situated on your left or right. Also adorning the monitor's front are an LED (indicating whether or not your monitors are on at any given time) and a dedicated headphone output (for private listening; please note that plugging your headphones in will silence the monitors themselves).

You can connect mobile devices and other devices directly to the monitors via 1/8“, 1/4" or RCA inputs—but then again, feel free to skip all that and just go with Bluetooth. The monitors also come with isolation pads for reducing the transmission of structural vibrations.

Behringer MS-20 24-Bit/192 kHz Digital 20-Watt Stereo Near Field Monitors

The MS20 Studio Monitors from Behringer are a pair of extremely compact, 2 x 10-Watt nearfield monitors that feature high-resolution 24-bit/192 kHz D/A converters. With the MS20, you can connect directly to your digital signal sources and eliminate annoying analog line-loss and hum forever. Whether you connect to your computer sound card, keyboard, or MP3 player, you will enjoy exceptional sound quality with great dynamics. The built-in amplifiers provide lots of headroom, while the powerful woofers and tweeters provide ultra-linear frequency response.

The MS20 connectivity includes stereo 1/8" and RCA jacks, which can be used simultaneously or mixed with a digital stereo source. Digital duties are handled by either RCA or TOSLINK sockets, providing for ultra-simple hookup. Individual volume controls for both Line inputs plus Bass and Treble EQ controls are provided on the front panel, along with a 1/4" headphone jack that automatically mutes the internal speakers.

Sound Quality
Sporting 3.625" woofers and 2.5" high-resolution tweeters, MS20 monitor speakers bring quality audio within the reach of anyone that operates a computer workstation. Whether you're a musician tracking your latest masterpieces, or just someone who listens to your favorite songs at work, MS20 loudspeakers will make them sound significantly better. They also make excellent add-on speakers for electronic keyboards. Front-mounted volume and individual bass and treble controls make accurate sound adjustments a breeze.

Built-in Mixer
The MS20 takes audio to an even higher level with its multiple input options. The built-in mixer features 1/8" stereo inputs for connecting CD/MD/MP3 players, dual RCA jacks for tape decks and stereo keyboard modules, and even both RCA and TOSLINK connectors for digital signal sources. This adds up to a system that lets you play along with a variety of prerecorded tracks. And you can wail away to your heart's content in total privacy, thanks to MS20's powerful headphone jack.

PRICE PER UNIT

A revolutionary formula: 2 x 7 = 77

In some set-ups it can be advisable to use a horizontally designed speaker rather than a vertical one. Until now, such monitors were only available within the SX top line.

The brand new A77X, due to its outstanding features, might become a true game changer: Equipped with the same advanced technologies as the A7X, it therefore is very similar to the two-way speaker. The A77X, however, distinguishes itself by much higher, compression-free maximum sound pressure levels and dynamics. Due to its power and radiation characteristics, it also is perfectly suited for both near- and midfield monitoring.

Driver technology

Like all models of the AX series, the A77X features the ADAM proprietary X-ART tweeter. The ʽXʼ stands for ʽeXtended frequency responseʼ and thus for one of the features of the Accelerating Ribbon Technology that has been drastically improved: the frequency response. It now extends all the way up to 50kHz. In addition, the X-ART tweeter has higher efficiency and higher maximum sound pressure levels.

The two 7” woofers are identical with that of the A7X. With their large voice coils (1.5”) and powerful amplifiers, they are capable of both very high maximum sound pressure levels as well as very deep registers. The woofers do not cover the same frequency bands: while both of them are responsible for the (sub-) bass frequencies up to about 400Hz, only one of them reproduces the midrange. This prevents interferences between the two drivers. For stereo setups the A77X is available in A and B versions in order to guarantee a precise stereo image.

Amplifiers / controls

Each driver has its own dedicated amplifier. A 50W A/B amp is responsible for the X-ART tweeter, while the bass-/midwoofers are driven by a 100W PWM amp each. The front panel includes a power switch and a control for the volume that retains the volume setting independently from the on/off switch.

The rear panel features several additional controls: a gain for the high frequencies (± 4dB) and two shelf filters for high and low frequencies.
To ensure greater compatibility, there are both XLR (balanced) and RCA (unbalanced) connectors.

Review samples:

“… a refreshing change“
"… if you liked the A7X youʼll like the A77X even more, and if the companyʼs smaller near-fields werenʼt your cup of tea, the A77X are definitely worth another listen. They are not much bigger than a two-driver cabinet design, so should slip into any installation where a near-field speaker will fit, but the extra low/ mid frequency drivers mean that the bass is more naturally extended and the mid-range clearer and more detailed. I like the A77X a lot and they make a refreshing change from the usual mid-priced near-field speakers." AUDIO MEDIA magazine / February 2012

“… wide and spacious soundstage with solid left/right imaging“
