The pinnacle of the A Series, the A8H is a 3-way speaker that delivers the extremely accurate and analytical sound required for critical-listening environments.
SUPREME MONITORING
The A8H incorporates an 8-inch resonant Multi-Layer Mineral (MLM) fiber woofer, innovative midrange driver, and handmade precision X-ART tweeter, which together produce an ultra-wide frequency response.
Like the other members of the A Series family, the A8H gives you tremendous flexibility for fine-tuning the sound through rotatable HPS waveguide technology and onboard DSP. At home across a full range of audio applications in mid- to full-sized spaces, the A8H is the right choice when you’re looking for the most detailed representation of your audio.
- The A8H is available in a left and right version.
- German Handmade Precision X-ART Tweeter with rotatable HPS waveguide
- 8'' Woofer (Multi-Layer Mineral)
- 3.5" DCH Midrange Driver
- Total Peak Amp. Power: 340 W
- Frequency Response @ -6 dB: 31 Hz – 45 kHz
- Max. peak SPL per speaker at 1 m: 105 dB SPL
Explore the technology
ADAM Audio monitors have earned a worldwide reputation for the innovations that we have established in the field of loudspeaker technology. Here you can explore the technology of the A8H.
A Control Remote Software
The DSP-based functionality of all A Series monitors can be controlled remotely and in real time over ethernet using A Control.
Rotatable HPS Waveguide & X-ART Tweeter
Made from a new glass fiber polymer compound, the HPS waveguide enables the X-ART tweeter to disperse sound in space with controlled consistency.
Automated Room Correction with Sonarworks
ADAM Audio is proud to partner with Sonarworks on an automated room correction solution that runs directly on the DSP of A Series monitors.
Hybrid Amplification
The A Series combines the best of both digital and analog worlds.
Multi-Layer Mineral Woofer [MLM]
The latest materials and advanced analysis and design processes have led to the development of our new long-throw woofers.
Midrange Driver
A Series midrange drivers deliver clean sound in the critical part of the frequency range where humans are especially sensitive to coloration of sound.
Voicings
A “Voicing” is a pre-defined sound profile of an A Series monitor. On the back panel, you will find two different selections, “UNR” and “Pure”.
Room Adaptation
On the back panel of A Series speakers, you will find four bands of room adaptation equalization: Bass, Desk, Presence and Treble.
Digital Signal Processing
The A Series capitalizes on the transformative power of DSP-based electronics to provide greater tuning precision than analog-only speakers.

Excellent value
Size: 16.9 Fl Oz (Pack of 15)
My son loves this water and Amazon is the easiest way for me to send him packs. Always fresh tasting and delivered on time. Perfect size bottles for him to carry in his backpack to school.

Clean, easy drinking water with a mild taste
Size: 16.9 Fl Oz (Pack of 15)
This bottled water has a clean and mild flavor that makes it easy to drink throughout the day. It is light and refreshing without any strong mineral aftertaste, which keeps it simple and consistent.
The bottles are convenient for carrying around, and the 15 pack is practical for keeping stocked at home, work, or in the fridge. They are easy to open and store without taking up too much space.
I like that the taste is consistent across bottles and works well for everyday hydration without any added flavor or heaviness.
One thing to keep in mind is that it is a very basic bottled water option, so it stands out more for convenience and consistency rather than anything unique.
Overall, this is a reliable everyday water choice that is simple, clean tasting, and easy to keep on hand.

Cheap and delicious water.
Size: 16.9 Fl Oz (Pack of 12)
Delicious! I can't stand some bottled water like Dasani, but once I got it ice cold, it's really nice. Bottles arrived in perfect condition with no leaking.
