Designed by acoustician Norman Varney, the Metu panels use reactive/diaphragmatic absorption tuned to an average NRC of 1.00 while being finished to disappear into a room — painted to match walls or dressed up as framed photos and posters rather than looking like foam egg-crate. A/V RoomService is a small Ohio-based specialty acoustics shop that designs, fabricates, and hand-finishes each panel to order rather than mass-producing a stock SKU, and it sells direct and through a limited dealer/integrator network rather than wide retail distribution.

Made by Acoustic Geometry of Chaska, Minnesota, the Curve System diffusors use a cylindrical, constant-radius wooden-framed front to provide phase-coherent, broadband diffusion, with a built-in mass-loaded-vinyl membrane bass absorber behind the diffusing face. The company is a small specialty room-treatment maker (not a mass-market brand), sells direct and through a limited dealer network, and each panel is available in a wide range of fabric, paint, and wood-veneer finishes rather than a single fixed SKU — reviewed favorably by Stereophile's John Marks.

The RAF-48H is an air-floating isolation platform that suspends audio components on a cushion of air rather than springs, elastomers, or mechanical bearings — a structure borrowed from electron-microscope isolation tables. Its hickory top plate and cabinet (upgraded from the original RAF-48's birch plywood) are said to lower the center of gravity and add dynamism, while air pressure is adjustable via an included hand pump without removing the component.

The BaffleCloud is an acoustic treatment product made by Acoustic Sciences Corporation (ASC) for reducing RT-60 in large spaces with high open-plenum ceilings. It is designed to be suspended in a grid and reduce noise buildup in spaces with large numbers of people.

The Bastoni Panel is an acoustic treatment product made by Acoustic Sciences Corporation for ambience alignment at the front and rear walls of high-performance, high-power audio playback rooms. The Bastoni product line includes small panels and smaller versions sized to drop into acoustic-tile ceiling T-bar grids or be flush-mounted to walls. This is a legacy product and is no longer manufactured.

The Billie Jean Drum Cover is a kick drum cover recreated by Acoustic Sciences Corporation (ASC) and Bruce Swedien. It replicates the original kick drum cover used for Michael Jackson’s “Billie Jean,” recorded in 1982; no materials, dimensions, or other technical specifications are stated.

The ASC CeilingPanel is an acoustic building block for controlling room acoustics, manufactured by Acoustic Sciences Corporation. It is designed to control directional noise by creating an acoustic “speed bump” and is intended for large rooms, including restaurants, auditoriums, band rooms, churches, day care facilities, gymnasiums, home theaters, studios, and high-end listening rooms.

Acoustic Sciences Corporation manufactures custom commercial-grade in-line mufflers for HVAC systems, industrial machinery, and material-handling applications. The mufflers combine built-in bass traps with standard treble-range absorbing panels and use acoustic-grade fiberglass to convert noise into heat energy. Designs maintain an open flow path for air or other materials and are configured for low head loss, with applications including reducing HVAC airflow noise and acoustic crosstalk through ducts.

The dRC-1 is an audio-room product made by Acoustic Sciences Corporation. Its listed applications are soundproofing and acoustic treatment. The page discusses high-performance audio rooms with low interior sound levels and fast acoustic response, where a floating wall can shake and excite a supporting stud when the tone frequency matches the stud’s resonance.

The HalfRound TubeTrap Isothermal is an acoustic treatment product made by Acoustic Sciences Corporation (ASC). It is a half-round, compact, modular unit designed for wall or ceiling mounting and placement in wall and ceiling patterns or room corners, combining broadband sound absorption, diffusion, and directional control of sound reflections.

The ASC IsoDeck is a floating floor-deck isolation system manufactured by Acoustic Sciences Corporation. It uses a high-density woven 1-inch felt strip as a slot-loaded spring, lightly glued into a 3/4 × 3/16-inch rabbeted groove in the bottom of each joist. The joist tops are covered with WallDamp damping polymer, while two subfloor layers rest on the joists with WallDamp squares between them to provide floor isolation and vibrational damping.

The IsoTile Ceiling Panel is made by Acoustic Sciences Corporation (ASC) for isolating and absorbing ceiling-transmitted noise in both directions. It is installed by placing it on top of existing acoustic ceiling tiles and is engineered to block and absorb sound.

MixCloud is an acoustic treatment panel made by Acoustic Sciences Corporation (ASC) for recording studios, mix-down rooms, post-production suites, A/V work rooms, project studios, and home studios. It provides broadband acoustic control by absorbing vertical sound reflections, including primary monitor and console reflections, and is suspended from the ceiling using four eye hooks attached to wire; Guilford Stock Fabrics are available for custom fabric colors.

The MixStation is an acoustic-control system by Acoustic Sciences Corporation, engineered by Art Noxon for small- to mid-sized mixing rooms. It consists of three large wall-mounted MixStation units and ten SoundPlanks, with built-in low-frequency bass trapping in the front-end arrays and SoundPlanks positioned on the wall opposite the listening position. The front SoundPlank arrangement remains fixed, while the rear arrangement can use either of two layouts.

The PicturePanel is an acoustic treatment made by Acoustic Sciences Corporation (ASC). It combines sound absorption and diffusion technologies derived from ASC’s SoundPanel and SoundPlanks with a customizable printed canvas suitable for homes, offices, or public spaces.

The QuarterRound TubeTrap IsoThermal is a quarter-cylinder acoustic bass trap manufactured by Acoustic Sciences Corporation, hand-built to order in Eugene, Oregon, and made in the USA. It uses patented IsoThermal technology with a flow-resistive membrane surrounding a capacitive air volume, includes a built-in polycylindrical treble diffuser, and provides twice the bass absorption of the Standard TubeTrap line while operating across the same frequency range as the full-round model.

Acoustic Sciences’ QuickSoundField is a recording-environment configuration built from eight StudioTraps arranged in a circle around an omnidirectional microphone and the performer. The StudioTraps acoustically “shadow” the room surfaces, leaving the bare room as a low-level, diffusive, time-delayed ambience and enabling adjustment from studio-dead to more live-sounding results. The StudioTraps can also be positioned beside monitor speakers, and with ASC MonitorStands the system can be converted into an AttackWall mixing/editing workstation.

ASC’s Studio Grade Mufflers are custom-built HVAC in-line mufflers for recording studios, designed to reduce duct noise and acoustic crosstalk. They combine streamlined straight-duct inserts for treble absorption with an “inside out” TubeTrap for bass absorption, along with standard treble-range absorbing panels. The mufflers use fiber-sealed fiberglass materials and are designed to prevent fiberglass particles from entering the room under air turbulence.

StudioTrap is a pair of portable acoustic treatment units for studio and live environments, described as a modified TubeTrap with adjustable treble absorption and diffusion, 360-degree mid-bass trapping, and variable height. Each unit has a built-in stand, sturdy exoskeleton, tripod foot, GreenGuard-certified core, and fiber-sealed construction covered in acoustically transparent micromesh and 100% recycled Guilford of Maine acoustic fabric. The manufacturer is not explicitly identified on the page.

The ASC Tube Trap is a cylindrical, modular broadband bass trap and diffusor that has been a mainstay of professional studios and high-end listening rooms for decades, prized for its combination of deep low-frequency absorption and an integral treble-range diffuser on one face (source: https://www.acousticsciences.com/product/tubetrap-bass-trap/). Its round, air-cavity-loaded design is "impedance-matched" to sound, allowing it to act as a fast-reacting bass absorber typically placed in room corners behind speakers or at the listening position (source: https://www.acousticsciences.com/product/tubetrap-bass-trap/, source: http://www.asc-hifi.com/tube-trap-technicals.htm).

ASC WallWool Batting is an acoustic insulation product manufactured by Acoustic Sciences Corporation for interior wall sound absorption and isolation. It consists of 1-inch-thick ceramic/refractory fiber wool with no fiberglass resin adhesive, glue, or formaldehyde, enclosed in an acoustically transparent Tyvek-type envelope. It is available in 16-inch or 24-inch widths, custom lengths up to 10 feet, and one-sided, two-sided, or unbacked configurations; a listed roll size is 1 inch × 2 feet × 25 feet with mounting tabs.

The BAD (Binary Amplitude Diffsorber) Panel is RPG's classic hybrid absorber/diffuser: a fabric-wrapped rigid fiberglass panel with a precision binary perforation pattern that absorbs strongly through the midrange, rolls off above 1 kHz, and transitions to a scattering diffusive surface at higher frequencies — letting a single panel type control both reflections and reverberation without deadening a room's high end.

DaaD ("Diffusion Absorption Acoustic Devices") is a lobe-shaped, free-standing corner treatment from Italian acoustics specialist Acustica Applicata that combines fast low-frequency resonance trapping with high-frequency diffusion in a single hand-finished column, using a micro-pressed metal front sheet over a tuned resistive layer. Acustica Applicata is a small Italian boutique manufacturer sold through a limited network of specialist hi-fi dealers rather than mass retail, and the DaaD line has a sustained reputation among European high-end enthusiasts, reviewed by Hi-Fi+ and profiled in 6moons' acoustic-treatment coverage.
