ADAM Audio A77X 3-Way Active Studio Monitor - Left, Single

Three-way active near-field monitor with two 7" woofers

Product Description

The ADAM Audio A77X is a three-way active near-field monitor with two 7-inch woofers and a custom X-ART tweeter. Capable of accurately recreating an extended frequency range of 38 Hz - 50 kHz, the A77X delivers unprecedented clarity. Equipped with the same advanced technologies as the award-winning A7X, these versatile monitors are a favorite among studios worldwide.


A77X studios monitors utilize custom hexagon woofers. Each woofer is equipped with a proprietary honeycomb Nomex structure, making them extremely lightweight and rigid. The added durability allows A77X to reach extremely loud volumes without the cones breaking up or distorting. Each component in the A77X woofers are precisely aligned for optimal low frequency reproduction, so you can rest easy knowing that your low-end will translate perfectly to any system.


ADAM monitors are known for their famous extended-frequency Accelerating Ribbon Technology (X-ART) tweeters, and A77X monitors do not disappoint. These state-of-the-art tweeters are capable of accurately reproducing frequencies from 38 Hz - 50 kHz for world-class sound quality. X-ART tweeters are handmade in Germany to ensure to the highest quality construction. By folding the X-ART diaphragm, a larger foil can be used, which significantly improves dynamics range and transient response. This custom pleated diaphragm allows A77X monitors to reach maximum SPLs of up to 122 dB.


Adam A77X studio monitors are equipped with two 150-watt and one 75-watt Class D amplifiers. These Pulse Width Modulation, or PWM amplifiers, allow for maximum efficiency. These powerful amps also cut down on internal temperatures, removing the need for heat sinks and reducing the overall weight. A77X studio monitors use the new PWM technology and state-of-the-art input and filter sections to deliver the most pristine audio possible.

I purchased a pair knowing they are being phased out. The control room at a college I'm attending uses the A77X for tracking and playback during sessions. I immediately knew I wanted a pair for my studio. 1st, 2nd and third semester of the Audio Engineering courses gave me time to really focus on the sound of these monitors when tracking and playback of various bands we recorded for grades. I use Focal monitors in my home project studio and finally added these as my main tracking, and playback. I'm still learning these monitors for mixing. So far, I'm happy with the monitors and Vintage King's customer service. The monitors arrived unblemished and in perfect condition.

I love it.

Excellent speakers full of love, make me want to kiss a dove. In the morning, listen loud, like you’re playing for big crowd. Make a song, or make two, as good as a pot of mama’s stew.

I love this monitor. I booked a listening session at Vintage King with my engineer friend whose ears I really trust, and we spent a solid hour or more meticulously testing all of the monitors in the $2-$4K range against each other. This one kept winning for both of us so I when I decided to buy it I assumed it would be $4K for the pair as I liked it more than expensive Barefoots or Focals, but these are only $2500 for the pair! I love the imaging on these, the low end bass response, and the warmth of them in the way the low mids are kind of pushed compared to some other monitors. The only other monitor I liked as much was the Dynaudio Core 7, which sounds nothing like these Adams, but is also really, really great. The Core 7's are $4K though whereas these again are $2500, so I went for the Adams A77X's and am really happy with them. Now my mixes are getting even a bit better, and my studio looks WAY sexier now too :)

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
