Professionally restored and offered by HQaudios. This listing is for the actual pair shown in the photographs.
These AR-58BX speakers were not simply cleaned, tested, and placed for sale. They went through a comprehensive restoration process covering the cabinets, driver suspension systems, crossover networks, connections, cosmetic presentation, and final performance.
HQaudios restored this pair with the goal of addressing both the technical and cosmetic age-related issues commonly found in vintage loudspeakers.
Each stage of the work was inspected before the speakers moved to the next restoration department.
The result is a pair that presents dramatically better than an unrestored example while retaining the character of a genuine vintage Acoustic Research loudspeaker.
Both crossover networks were removed from the cabinets for inspection and service.
Our objective was to service the existing network while preserving the electrical design and voicing intended for the AR-58BX.
A major difference between a professionally restored HQaudios product and a typical used vintage speaker is the QC process.
The product does not rely on a single final inspection. Each department has its own QC checkpoint before the speakers are allowed to move to the next stage.
After technical service, the woofers, midranges, tweeters, crossover networks, internal wiring, and speaker connections are inspected and tested. The speakers must pass functional testing before being released to cabinet restoration.
The new wood veneer, painted front baffles, grille cloth, cabinet surfaces, terminals, and overall cosmetic condition are inspected after restoration. Cosmetic issues must be corrected before the speakers are approved for photography.
Before publication, our Media team photographs the actual pair and verifies the model, physical condition, visible restoration work, and product details. The photographs in this listing show the actual speakers being offered.
Before shipment, the pair receives another condition check. The packing team verifies that the speakers, grilles, cabinet corners, veneered surfaces, and front baffles are properly protected for transport.
After restoration was completed, the finished pair was tested for:
This pair passed final testing and is fully operational and ready to enjoy.
This pair has undergone extensive cabinet and exterior restoration including new real wood veneer, restored front baffles, restored grille frames, and new grille cloth.
These remain genuine vintage loudspeakers, so minor age-related characteristics may still be present. Please inspect all photographs carefully.
The photos show the actual pair you will receive.
Vintage speakers can look good externally while hiding deteriorated surrounds, aged connections, crossover issues, previous repairs, or cosmetic damage.
