Bill Fitzmaurice Designs TLAH Home Theater Array
The benefits of a line array are high sensitivity, wide horizontal dispersion, and a high degree of vertical pattern control
The TLAH combines the features of line array, transmission line and horn-loaded enclosures in an easy to build cabinet.
Only 40 inches high, and extending less than eight inches into the room,
these speakers project a huge soundstage similar to that formerly available only with large horns.
The triangular version may be mounted a room corner, or hung mid wall.
The rectangular version may be wall hung or floor standing.
TLAH DIY Line Array Cabinet
TLAH gives a combination of high sensitivity, wide horizontal dispersion and tight vertical pattern control that traditional point source speakers can't deliver.
8 drivers for 4ohm,or 9 drivers for 8 ohm, 12 tweeters
40 inches tall, it may be made triangular for wall hung or rectangular for floor standing.
With 102dB/watt sensitivity, even small powered amps provide plenty of output.
