The classic ALTEC 606A concept is known for its substantial cabinet proportions, bass-reflex layout, and suitability for high-efficiency loudspeaker systems.
HQaudios' custom version preserves the visual character and large-format presence associated with this design while using newly manufactured construction, real walnut veneer, and clearly defined mounting specifications.
It provides a practical foundation for enthusiasts restoring an Altec-style system, replacing an aging cabinet, or building a new vintage-inspired loudspeaker around compatible high-efficiency components.
Each cabinet is constructed from approximately 0.71" full-birch plywood, selected for rigidity, structural strength, and long-term stability.
Internal structural members reinforce the large cabinet panels and provide a stable foundation for the loudspeaker components installed inside the enclosure.
The exterior is finished in real walnut veneer, giving each cabinet the natural grain and warm appearance associated with classic large-format loudspeaker cabinetry.
A brown PU protective finish is applied to the exterior, while the front presentation is completed with cream / light-beige grille cloth mounted to a plywood grille frame.
Titebond wood adhesive is used during cabinet assembly to create strong bonded joints throughout the enclosure structure.

The cabinet follows an ALTEC 606A-style large-format bass-reflex concept, with a front vent integrated into the enclosure layout.
Because this product is an empty enclosure, final frequency response, sensitivity, impedance, power handling, bass tuning, and overall sound quality depend on the actual driver, crossover, damping, sealing, wiring, port configuration, amplifier, and system setup selected by the buyer.
The cabinet provides the physical and acoustic foundation for the completed loudspeaker system, while the final system performance is determined by the full component configuration.
Before ordering these cabinets for an existing loudspeaker project, please confirm the following:
The ALTEC 606A design reference does not guarantee compatibility with every vintage Altec driver or reproduction component.
Professional installation is recommended when completing the loudspeaker system.
Because these cabinets are custom manufactured, selected details may be reviewed before production to better suit the buyer's intended loudspeaker project.
Depending on the project, custom details may include:
Any requested dimensional or component-layout changes must be confirmed before cutting, drilling, veneering, or finishing begins.
These are newly manufactured custom wooden speaker cabinets, not used vintage cabinets.
Because genuine walnut veneer is a natural material, differences in grain pattern, color tone, and surface character between cabinets are expected and are not considered manufacturing defects.
Actual color may also vary slightly due to lighting, photography, screen settings, and the natural appearance of the veneer.
The following audio components are not included unless specifically stated:
Any completed loudspeaker systems or audio equipment shown in demonstration photographs are for visualization purposes only unless explicitly identified as included.
Because of their large dimensions and finished veneer surfaces, these cabinets require careful protective packaging.
Cabinet edges, corners, grille areas, veneer surfaces, and the overall structure will be protected using reinforced wrapping, dense cushioning, and heavy-duty packaging.
Freight shipping may be used depending on destination, package dimensions, and carrier availability.
These custom-made wooden cabinets are backed by our 10-Year HQaudios Warranty against manufacturing defects under normal indoor use.
The warranty does not cover incorrect installation, improper cutting or drilling, incompatible components, unauthorized modification, moisture or water exposure, excessive heat, prolonged direct sunlight, impact damage, improper transportation after delivery, natural wood-grain variation, or acoustic results caused by customer-selected components and system configuration.
These are newly manufactured ALTEC 606A-style replacement cabinets.
They are not original vintage ALTEC factory cabinets unless explicitly stated otherwise.
The ALTEC name and 606A reference are used to identify the historical design inspiration and intended application of the cabinet.
Please confirm driver compatibility and any requested custom specifications before production begins.
HQaudios can assist with cabinet dimensions, driver compatibility, installation planning, finishing options, shipping, and warranty questions before purchase.
