Post Subject: Framed midbassPosted by noviygera on: 9/7/2013

lately I've come to theorize that the horn midbass may be a contadictive dead end approach. The reason is that proper horn midbass (lets say 80 to 400Hz) will be a big one and present a few inherent "brick walls". It will physically shade the midrange or high sections. It will throw a coverage pattern that is sourced from one point and be possibly localized at the upper end of it's frequency range, if using 1st order crossovers.
Let's picture another approach. An array of small, capable direct radiators, let's say 5" or 6" paper cones in sealed enclosures that do well 80 to 400Hz. Physically time aligned with the horn mid/high sections, hugging from all sides. A row below, above, right, left of the mid/high horn. A frame of midbass speakers. Efficiency will be low, but many advantages -- no shading, a stable sound field, good pattern control and low room interaction vertically and horizontally.
