unclestu, this is all fairly new to me. The recipe for the HRSCF calls for TI-Shield.

TI SHIELD: Unique composite shielding material from Texas Instruments for blocking EMI & RFI interference. Conventional shielding materials excel either in electrical conductivity or magnetic permeability, but not both. Steel is not conductive enough to be effective at blocking high frequencies, while copper and aluminum are not effective at absorbing low frequency EMI. No single material met both of these requirements until TI developed this copper/alloy 49/copper composite material. TI Shield is effective from below 10Hz up to 10GHz and is currently available only in .014" thickness (28-29ga). Counterpoint utilized sim- ilar technology in construction of their chassis' and found significant audible benefits were to be derived from surrounding audio circuitry with materials that shield against both EMI & RFI. Unlike Mu-Metal, this material may be cut and bent into conven- ient shapes without requiring annealing to restore its shielding properties.
12" x 12"/$32.50, 12" x 24"/$64.50, 12" x 48"/$127.00 --- NOT CURRENTLY IN PRODUCTION. From Percy Audio catalog.

Has anyone here built these speaker filters. Can you recommend a replacement material?
