Earthshattering Output from This Tapped Horn Subwoofer

The Danley Sound Labs TH118 is a roadworthy passive subwoofer with an 18-inch, long-excursion low-frequency driver in a Tapped Horn alignment for maximum output from a smaller-sized cabinet. This sub's impressive linearity and high power handling produce rafter-shaking low end, and its polyurea-coated, 13-ply, Baltic birch enclosure ensures near-bulletproof durability and reliability. This Touring Version of the Danley Sound Labs TH118 boasts M10 suspension points, in addition to three pole cups, for flexible installation.

Danley Tapped Horn ensures rafter-shaking low end

Here at Sweetwater, we're blown away by the TH118's massive sound, especially considering its relatively compact footprint. This is due to Danley's super-efficient Tapped Horn design, which takes full advantage of the sub's 18-inch, long-excursion low-frequency driver by doubling its output capacity. Add to that the TH118's near-perfect linearity in its passband and robust power handling, and you have one of the most powerful subs you'll find anywhere. This sub is so powerful, in fact, that Danley states it would take two conventional 2 x 18-inch front-loaded subwoofers to equal the output of a single TH118.

Danley Sound Labs TH118 Features:

  • 18-in., long-excursion low-frequency driver boasts thunderous bass with robust power handling
  • Tapped Horn design delivers more volume from less input
  • Produces an output comparable to 2 conventional 2 x 18-inch front-loaded subwoofers
  • Exhibits near-perfect linearity in its passband
  • Polyurea-coated, 13-ply, Baltic birch enclosure ensures maximum durability and reliability
  • M10 suspension point and 3 pole cups ensure flexible installation

Reviews

Best Subs Ive ever owned
Luke at Sweetwater always does a great job helping me with my equipment needs. I have owned 12 of the Danley TH118s for about 10 years, Done some very large events, and Never blown one! I think they are one of the best sounding subs out there, so I just bought 4 more.
Thanks Luke

I own 2 of these subwoofers and would recommend them over most dual 18" subs. Considering size/weight/volume, there is nothing else on the market I've heard that gives this level of clean SPL. The form factor with makes them every easy to move as they already come with castors, and are actually easier to handle than most smaller/lighter single 18" solutions. They can also be ordered in a powered version, or it isn't difficult to install a Speakerpower amp yourself, which is what I've done with both of mine. Highly recommend!
