Sound contractor Tritech Light and Sound (Middletown, Ohio), whose credits include the Cincinnati Blues Festival, the New Year’s Festival in Columbus, the Jerry Lewis MDA Telethon and live acts such as Iron Butterfly and 50 Cent to Dave Chappelle and more, has recently added six speakers to owner John Hutton’s roster of 12 existing SPL-td1 loudspeakers.
“We’ve been using the 12 original td1s for four years,” he says, “and we realized that we needed more. When you need to do events that have large crowds, like the King Biscuit Jazz Festival I attended, you simply need that many loudspeakers to do the job.”
A multiple-entry horn, the td1 uses patented Unity Summation Aperture design to combine the outputs from multiple drivers to power a single horn. The result is that each driver operates in its own frequency range, resulting in a multiple-driver horn design that is automatically time/phase correct. When combined with projection accuracy features, the td1 delivers a precise representation of sound across the frequency range.
“The td1 has been a very reliable speaker for us. It does what they say it will do. They really throw the sound,” says Hutton. “Line arrays are made for long-throw applications, but you have to apply many rules to achieve the correct configuration and optimum performance. From a practical standpoint, if you’re not schooled in that and you’re in a hurry, those things don’t get done. It’s all about how you set up a line array. If you don’t do it right, they don’t work right. With the td1, you groundstack or fly them, get some basic visual alignment and you achieve great results.”
