AEA R44 Series & RCA 44 Grille — a complete replacement grille set for AEA R44 series and original RCA 44 microphones, including exterior grille panels, interior acoustic silk, and mounting screws, available in four finishes matched to specific historical and current R44 variants.
The RCA 44's diamond-pattern grille is not purely a visual element — it is the primary mechanical barrier protecting the 1.8-µm aluminium ribbon from air blasts, airborne particles, and stray magnetic material. A dented, corroded, or structurally deformed grille is a direct threat to the ribbon element behind it. AEA manufactures the Grille Set as a factory-accurate replacement: identical diamond pattern geometry, same mounting hole positions, and the same interior acoustic silk that sits between the outer grille and the perforated metal blast screens flanking the ribbon on both sides.
Four Finishes — Four Historical and Current Variants
Finish selection here is a technical and historical service decision, not an aesthetic one. Satin Chrome is the most common variant, fitted to the majority of RCA 44BX production and the standard finish for general service replacements. Bright Chrome appears on early RCA 44B models with a black transformer case — a rarer configuration sought by collectors restoring pre-1945 factory specifications. Satin Nickel is the finish specific to the AEA R44CE, the cost-effective exterior variant with identical internal components to the R44C. Black — matte lacquered — is used in stage and film applications where chrome reflections conflict with camera lighting setups. All four finishes are produced by AEA on the same lines as parts fitted to new R44 microphones leaving Pasadena.
Service and Restoration to Original Spec
An RCA 44 grille after decades of use typically shows transport dents, corrosion at the contact points with the yoke, or degraded interior silk — each condition reduces the acoustic protection of the ribbon and affects the high-frequency behaviour of the microphone. The AEA Grille Set restores original geometry and acoustic shielding in one package: outer panels, silk, and hardware cover the complete replacement without sourcing parts from multiple suppliers. For technicians working with vintage RCA 44s and owners of AEA R44 microphones, this is standard bench stock.
