Neil Blanchard Wants to Sell You a Flatpack Transmission Line Loudspeaker System

or for $100, just the plans

He'll sell his transmission line speaker to you as a $100 plan, and hopefully soon as a "flat pack' you self-assemble and then buy the crossover network and drivers from Madisound. Package cost is max $1000.00/pr.

Blanchard showed off his creations in partnership with Geshelli Labs—the Florida-based family cooperative that builds DACs, and headphone amps. He's hoping to have all of this up and running very soon.

    Cool. I owned IMF Studio II A's back in the day. Wondered why no one kept up with this type of design.

    There are a few manufacturers that use transmission line designs - UK's PMC and France's Jean Marie Reynaud to be exact. I recall John Atkinson of Stereophile reviewing some and not being a big fan of the design philosophy compared to traditional speaker design techniques. You can read around - its a polarizing design philosophy for some reason
