Audio professionals in need of a high-quality nearfield monitor will be impressed with the black Adam Professional Audio A4V, a professional, 4" 2-way studio monitor speaker that delivers rich, spacious, and enveloping sound, well suited for small studio spaces, short listening distances, and immersive multispeaker configurations.

A 110W RMS Class-D amplifier powers the 4" Multilayer Mineral (MLM) woofer, while a 20W Class-AB amplifier drives the X-ART tweeter with HPS waveguide to provide an ultrawide frequency range (52 Hz to 45 kHz). The rotatable High-Frequency Propagation System (HPS) waveguide technology and onboard DSP allow you position the monitor either horizontally or vertically, while fine-tuning the speaker to your precise requirements.

• ADAM Audio HPS (high-frequency propagation system) waveguide technology enables tweeters to disperse sound with controlled consistency, broad in the horizontal axis but tightly focused on the vertical plane. The A Series introduces a rotatable HPS waveguide design. You can shift A Series tweeters in 90-degree steps to continue to benefit from HPS waveguide technology, whether you position the speakers horizontally or vertically.
• The A Series HPS Waveguide is made from a new glass-fiber polymer compound that helps create a clear sound, free of unwanted resonance. The ADAM Audio X-ART tweeter is at the heart of the rotatable HPS waveguide. Handmade in Germany, the X-ART tweeter provides a precise transient response and reproduces the finest sonic details. This X-ART tweeter is used in every A Series speaker, providing a detailed and consistent sound across the product line. 

A Series woofers are constructed with a unique blend of mineral stone fibers that have been baked together to create a lightweight but highly stable material. The mineral composition, layering, and geometry of each cone is specific to the driver used in each model. By combining this material with a new magnet system, A Series woofers produce high output with low distortion, delivering a clean low end.

• The A Series combines the best of both digital and analog worlds. The woofer is driven by a Class-D amplifier that help produce linear performance while reducing distortion. The amplifier was chosen specifically for its power and efficiency, in terms of both energy consumption and sound reproduction. Low thermal dissipation allows for a smaller heat sink, which facilitated additional investment in the exceptional power and performance of the A Series.
• The tweeter is powered by a Class-AB amplifier, which offer a smooth, natural reproduction of high frequencies. The amplifier is optimized for its working range, resulting in a fine-tuned, properly aligned speaker. To reach this point, ADAM Audio carried out extensive measurements and listening sessions, trialing countless amplifiers and amplifier components.

The A Series capitalizes on the transformative power of DSP-based electronics to provide greater tuning precision and better predictability than analog-only speakers. With firmware that can be updated through an Ethernet connection, over time you can expect to integrate the latest DSP-based capabilities from ADAM Audio, including new filter types and features, plus alternative voicings.

On the back panel of A Series speakers, you will find four bands of room-adaptation equalization: Bass, Desk, Presence, and Treble. Each band is adjustable in predefined steps, offering more than 100 tuning options to help compensate for the typical acoustic problems that arise from speaker placement.

• A Voicing is a predefined sound profile of the A Series monitors. On the back panel, you will find two different selections, UNR and Pure. Here you will also find the Ext option, which is dedicated to the extended functionality that comes with A Control via the Ethernet connection. 
• UNR or Uniform Natural Response is a dynamic and natural-sounding response curve of ADAM Audio’s own design, which stems from a variety of iconic ADAM Audio legacy products including the preceding AX Series. It lends itself to production, composition, and song writing, as its engaging and present sound can give you more room for creativity and flow. It is also a great option whenever you want to use your speakers simply to enjoy some good music. 
• Pure is a highly accurate and neutral sounding option. This is the flat setting, ideal for mixing and mastering, where you must be aware of all the details and rely on an honest representation from your speakers. 
• The Ext option is dedicated to the extended functionality that comes with A Control via the Ethernet connection. Using A Control’s six-band EQ, a custom voicing and be created and pushed to the monitor. 

• The DSP-based functionality of all A Series monitors can be controlled remotely and in real time over Ethernet using the free-to-download A Control software. A Control is available to download for Windows and MacOS in the MyADAM area of www.adam-audio.com for customers who have registered their A Series monitors.
• Once downloaded and installed, you can control multiple speakers at once, precisely adjusting equalization and delay settings from various listening positions in your studio space. While you work, you can remotely control monitor levels if you’re far from a fader or physical interface. Remote-control capabilities are particularly useful in multipurpose rooms, allowing you to make sure that voicing, EQ, and other settings are all exactly how you want them. 

A Series speakers are designed to be adaptable to changing requirements, preferences, and environments. Using the A Control software, you can push advanced filters directly to an embedded platform onboard the monitors to help compensate for imperfect room acoustics. This embedded platform supports filters from industry leading third-party Sonarworks. Using Sonarworks software and a measurement mic, you can calibrate your speakers for a new room or shifting taste.

The new A Series cabinets build on the heritage of ADAM Audio and the AX Series in particular. In an evolutionary design, A Series cabinets have deeper beveling to further reduce diffraction. Thicker baffle walls strengthen the cabinets and reduce internal vibrations, while a flared port design optimizes airflow and reduces port noise. All A Series speakers include an underside mounting interface, giving you the flexibility to mount them wherever you need them.

Q: 1. does the top part/plate come off?

A: Yes.The plates are removable.

Q: 2. Do these have a Prop65 warning on them?

A: The Pyle PSTND32 stands do not have a Prop65 warning.

Q: 3. Do the rubber tips come off the feet? I assume they do as I think says they also come with spikes for carpet, but I,m wanting to fill the three legs with sand, and reason this can’t work?

A: The rubber tips are removable.

Q: 4. can these be placed on top of other speaker stands?

A: We would not recommend that you stack these on top of floor stands. There is the possibility of stability issues that could cause the speakers to fall and get damaged and/or cause injury.

Q: 5. Hi will these work for the ADAM Audio T5V 5" Powered Studio Monitor or do i need the next ones up the medium ones ?

A: The area covered by the IsoAcoustics ISO-130 Small Speaker Monitor Acoustic Isolation Stands is small compared to the dimensional specification of the Adam Professional Audio T5V T-Series Active Nearfield Monitor (11.7 x 7.0"). The IsoAcoustics ISO-155 Medium Speaker Monitor Acoustic Isolation Stands (BH #ISO155PR) would provide better coverage in this scenario: https://bhpho.to/3GHBv4C

Q: 6. What is the minimum height(shortest) it will go?

A: Height Adjustment Size: 34.0’’ to 53.0’’ -inches

Q: 7. How many height positions are drilled into the pole. Illustration only shows one. How high will the platform go and still lock into place?

A: There are six predrilled holes, allowing for the height of the speaker stands to be adjusted in 3-inch intervals, starting at 36-inches and going up to as high as 54 inches

Q: 8. Are these stands too high at their minimum height to be used comfortably while sitting down? The specs say the minimum height is 36 , but that's quite tall. Are they actually 36 , or are they shorter?

A: Yes they are a little tall when sitting

Q: 9. Will these stands work with Dynaudio LYD 48 monitors?

A: While the Pyle Pro Universal Monitor Speaker Stands (Pair) can support the weight of the Dynaudio Acoustics LYD 48 monitors, the footprint of the speakers are much larger than the platform attached to the stand. It may not be the most suitable for speakers that large in size.

Q: 10. will the legs fit under a couch. how thick are the legs?

A: The steel tubing for the legs is approximately 1.5" thick and around 2" at the ends with the rubber feet included. Whether or not it would fit under a couch depends on the amount of space between your floor and the bottom of the couch.
