New Danley Subwoofer Goes to New Depths
Danley Sound Labs has announced the TH-215 subwoofer, the latest addition to their TH line of unusually compact and efficient subwoofers. The TH-215 uses Danley's patent-pending tapped horn technology to deliver honest sub-30Hz performance with audiophile fidelity in a light-weight, tour-friendly cabinet. It will find ideal applications in houses of worship, performing arts centers, and music venues ranging in capacity from clubs to arenas.
The 22" x 30" x 42" TH-215 is designed to cover the 29-125Hz range (+/-3dB) with a sensitivity of 99dB SPL at 39Hz (measured as 20V input 1/2 space at 10M distance). While it may be small in size when compared to conventional subwoofers, its sound is large. The TH-215 takes up to 1,400 continuous watts and 2,800 program watts and will produce a generous 133dB SPL at 36Hz and 138dB SPL in the range of 102-113Hz. Relative to its impressive output, the TH-215 weighs in at a modest 190 lbs. With a common sense recognition that even the best sounding subwoofer needs to be usable, the TH-215 is outfitted with intelligently-placed handholds and castors to make truck-packing and maneuvering a cinch.
"People are astounded by the deep, loud, true sound of our TH line subwoofers," explained their designer, Tom Danley. "It's uncommon for a subwoofer to reproduce with such fidelity, and it's unprecedented for a subwoofer that's so small. Our patent-pending tapped horn technology makes the difference. Conventional horns have to be one-half the length of the lowest wavelength that they are intended to reproduce. Since low-frequency wavelengths are quite large, conventional subwoofers have to be large too. Our unique tapped horn technology gets around this by cleverly placing taps in the horn where radiation from the rear side of the driver enters. The resulting phase cancellations and additions work out such that our subwoofers can accurately reproduce low frequencies with a much shorter horn."
Already recognized as an industry leader in innovative loudspeaker designs, Danley is known for his restless curiosity and knack for devising novel solutions to problems that the rest of the industry put to rest as insoluble long ago. While Danley has participated in a ground-zero bombing simulation, a jet engine active noise cancellation project, and the creation of a sonic-boom generator, his first and lasting love is the faithful reproduction and reinforcement of sound for studios, high-end home theaters, houses of worship, and live music venues of all sizes.
