Adam Audio A8H-A Left Side

The ADAM Audio A8H-A Side Left is a 3-way powered midfield studio monitor—presented here in the version to be positioned on the left—designed for medium to large studios, mixing, mastering, and critical listening. It features an 8” MLM woofer, a 3.5” DCH midrange driver, an X-ART tweeter with a rotatable HPS waveguide, 340 W of peak amplification, a frequency response from 31Hz to 45kHz, front-firing bass reflex, 96kHz DSP, A Control via Ethernet, SoundID Reference integration, and XLR/RCA inputs.

At the top of the A Series

The ADAM Audio A8H-A Side Left (to be positioned on the left) is the reference model of the A Series for medium to large environments and applications requiring an analytical and highly extended representation of the audio program. The 3-way system combines an 8" MLM woofer, a 3.5" DCH midrange, and the X-ART tweeter, with a response reaching 31 Hz at -6 dB and extending up to 45 kHz.

Three transducers, three optimized bands

The 8" woofer uses MLM material to maintain rigidity and control even at the excursions required by lower frequencies. The 3.5" DCH midrange handles the band between the 400 Hz and 3 kHz crossovers, freeing the woofer and tweeter from a significant portion of the spectrum. The X-ART tweeter, handcrafted in Germany, completes the system with a fast and detailed response in the high frequencies.

HPS waveguide and Left/Right versions

The rotatable HPS waveguide controls the tweeter's dispersion with an opening of 120° on the horizontal plane and 70° on the vertical plane. This version of the A8H is the "A Side-Left," designed to form a mirrored pair together with the "B Side Right." The manual nevertheless provides for the possibility of using either version as a center channel by aligning the acoustic axis at 0° relative to the listening position.

340 W peak, DSP, and remote control

The amplification section provides 250 W peak for the woofer, 70 W for the midrange, and 20 W for the tweeter, for a total of 340 W peak. The internal DSP operates at 96 kHz and integrates Room Adaptation, Pure and UNR voicings, protection, and system management. Through Ethernet and A Control, it is possible to intervene in real-time on advanced six-band equalization, level, delay, and configuration of multiple monitors.

SoundID Reference, connections, and installation

A Control allows you to load correction filters generated by Sonarworks SoundID Reference directly into the A8H's DSP, keeping the profile active within the monitor. Connectivity includes balanced XLR, unbalanced RCA, and RJ45; the cabinet features a front-firing bass reflex port and four M8 threaded inserts on the bottom for compatible mounting solutions. Dimensions are 274 x 382 x 329 mm (H x W x D) and the weight is 13.6 kg.

Who is it designed for and when to choose it

The A8H is the A Series choice for those seeking maximum extension, band separation, and performance in medium to large rooms. The Left and Right versions allow for correct stereo geometry, while the 8” woofer and 3-way configuration make it suitable for particularly demanding mix and mastering sessions.
