TLAH

The dilemma: You want a pair of high efficiency stereo/HT mains that will give you 99dB/watt sensitivity down to 80 Hz. You don't have room for large horn-loaded enclosures, you can't afford to spend a lot of money, and your woodworking skills are too rudimentary to build a complicated cabinet. The answer: TLAH.

The TLAH combines the features of line array, transmission line and horn-loaded enclosures in an easy to build cabinet. Only 40 inches or so high, and extending less than ten inches into the room, these speakers project a huge soundstage similar to that formerly available only with large horns. You may wall mount them in a room corner as shown, or hang them mid wall. You can use them freestanding as well, or stand mount them. They make a perfect main speaker system to compliment Tuba 18 or AutoTuba subs. Here's a 1m/1W SPL chart, measured outdoors, full-space:

Performance rivals commercial speakers that cost hundreds and even thousands of dollars, but they can be built for less than $150 apiece with commonly vailable drivers. If you're lucky enough to find closeout drivers you can build them for even less. A lot less. An awful lot less. The originals were built at a total cost, including lumber, of $60. For the pair. End of dilemma.

Also included: plans for a six foot high pro-sound version of TLAH, loaded with 8" drivers.

With well over 100dB/watt sensitivity, and the long-throw clarity than only a line array can give, this speaker is especially well suited for permanent installations in acoustically harsh environments, such as churches and gymnasiums.

Construction Degree of Difficulty: 5

Performance Quotient: 10

Equivalent Retail Value: $ 799
