Rated 5 out of 5

Absolutely amazing monitors

I've always chosen (relatively) large floor-standing sealed enclosures for my main listening area. A few years ago I downsized to eliminate the pre-amp processor and now use an O**o player, M**z power amplifier, with 25 ft. speaker cables, and HSU sub with good results. I decided to audition the Adam monitors and was amazed with the results. Using unbalanced cables I got significant hum at high monitor gain. Balanced cables eliminated this issue and I have wonderful imaging and excellent transient response. Rolling off the A77X at 60 Hz and bringing in the sub makes it even better.

Game Changer

Should have got these much sooner!

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, the A77X features the ADAM proprietary X-ART tweeter. The 'X' stands for 'extended frequency response' 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 one of them is responsible for the (sub-) bass frequencies up to about400Hz, the other takes over most of the midrange.

What's in the box:

  • Adam Audio A77X 7 " 250W 3-Way Active Nearfield Monitor (Speaker B)
  • Power Cord
  • Manual
  • Adam Audio 5 Year Warranty
