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

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.

My Heels Were in Bad Shape. Like… Really Bad
Color: Gray
These moisturizing heel socks with the gel cushions were honestly a small miracle for me.
After recovering from cancer treatments, my skin became extremely dry everywhere, but my heels were the worst. They cracked so deeply they looked like fissures and were even bleeding. I tried lotions and bandages repeatedly with very little progress.
A friend suggested I treat my heel like it might have a fungal component, so I applied Lotrimin cream, put these heel socks on, and hoped for the best. Within three days, my heels were fully healed. I completed a 7-day routine, and my feet have never been softer.
The silicone gel cushion is comfortable, soothing, and stays in place. I loved it so much that I still treat myself about once a week, even though I really don’t need to anymore.
They are also washable. I hand-washed mine in the sink and let them air dry, and they came out looking brand new.
If your heels are cracked, painful, or need serious care, I highly recommend these.

Ehh. Not for me.
Color: Gray
Foot slides when walking in them. The fit was tighter than lead to believe. It did hold the moisture in but the silicone patch is small

Transformative for Dry, Cracked Heels!
Color: Original Grey
I recently purchased Dr. Frederick's Original Moisturizing Heel Socks, and they have truly transformed the condition of my feet! I can’t recommend them highly enough.
Effective Moisturization: These socks are infused with moisturizing agents that work wonders. After just a few uses, I noticed a significant reduction in dryness and cracking on my heels. My feet feel softer and smoother, and I love that I can wake up to beautifully moisturized skin.
Comfortable Fit: The socks are incredibly comfortable to wear, with a snug yet gentle fit. I appreciate that they don’t feel restrictive, allowing me to walk around my home while wearing them without any discomfort. They are also lightweight, making them easy to slip on before bed.
User-Friendly: They are super easy to use—just wear them overnight, and let the socks do their magic. I love the simplicity of incorporating them into my nighttime routine.
Durable Quality: The quality of the socks is impressive. They wash well and have maintained their shape and effectiveness after multiple uses. I feel confident that they will last a long time.
Final Thoughts: If you're struggling with dry, cracked heels, I highly recommend Dr. Frederick's Original Moisturizing Heel Socks. They are a fantastic investment in foot care and have made a noticeable difference in the health of my skin. These socks have become a must-have in my self-care routine!

These worked for me!
Color: Original Grey
They worked great. I bought these for cracked sore heels. It took 2-3 weeks but my heels no longer hurt and the cracks have closed and look more like an indention than a crack now. They feel so much better, but I'll probably wear them another week just to be sure they stay healed. They look and feel like regular socks from the outside but only cover the heel with the toe open. Not think but not thick, again like regular socks. They would probably be slippery on a smooth surface the same as socks. The inside feels like rubber or something smooth at the heel. I have washed them once each pair and accidentally dried one pair in the dryer. They still seem to feel the same so I think they're fine. They're pretty inexpensive and had different colors and sizes.
