5 Epic EQ Presets

Choose from 5 epic EQ presets including ones specifically tuned for use with popular Soundboks speakers.

Left, Right and Mono Mix

Set DFB’s Audio Routing to LEFT, RIGHT or MONO MIX — yes, this means you can set up 2 DFBs as stereo subs if that’s what you want.


Dual tuned ports extend DFB’s bass down to 35 Hz and maximize SPL output.


  • Charge the internal battery and play DFB at full volume at the same time
  • Internal battery charges from empty to full in 2 hours using the included 125W brick power supply
  • DFB's battery fuel gauge LED stack displays battery life remaining — the bottom LED starts to slow flash when you’ve got 45 minutes left
  • A system with two DFBs and two Soundboks 4s pole mounted atop the DFBs is an ideal setup for the gigging mobile DJ
  • The above setup can be fed directly from the DJ deck by using a Dani SKAA transmitter, or alternatively, the DJ Deck can be XLR wired to one of the Soundboks 4s which in turn, can feed the remaining 3 speakers wirelessly via SKAA.
  • Ultra-simple 1-knob operation; yeah there’s an Owner’s Manual, but you won’t need to read it.  Just set your Soundboks to Host mode and start peeling the paint.
  • Mega flexible — when you do finally crack open the Owner’s Manual, you’ll find over 60 “sweet hookups”; more than 60 cool ways to use your DFB laid out in easy-to-understand hookup diagrams
  • DFB is built from high-grade birch plywood like many other quality PA speakers, however very few of those other speakers have interlaced-finger box corner joints like DFB.  Yep — 8 of them.  Tough?  It’s a beast.  Check the competitors’ cabinets — most don’t bother with anything this extreme, especially since you can’t see it.
  • 5 of 6 of DFB’s birch plywood walls are featureless — so 5/6 walls are pretty much impervious to impact damage
  • Gorgeous and robust speckle-paint matte black finish — yes, the classy one — it’s beautiful, tough and LIGHTWEIGHT
  • DFB’s massive, thick neoprene sponge rubber feet compress to prevent DFB from wobbling regardless of how uneven a surface DFB is placed on
  • Big rubber feet on its back wall protect the cabinet during transport and storage
  • Pop an industry-standard 1 3/8” (35mm) pole (not included) into DFB's bushing and loft a Soundboks 3, 4, Go or virtually any other powered speaker up top — no tripod stand needed
  • With its massive welded-steel 4” deep pole bushing, ultra wide stance and anti-wobble neoprene feet, DFB is a mega-stable pole base for your Soundboks or other pro-grade full-range top speaker
  • Two monkey grip handles enable serious manhandling while literally reducing DFB’s weight at the same time
  • Weather resistant — DFB is good to go, regardless of where and when your gig is happening
  • Gorgeous 3mm powder-coated aluminum User Interface panel — it’s hefty to make DFB tough, and it doubles as a massive heat sink for DFB’s audio amplifiers.  With a heat sink this big, DFB can actually deliver the full rated amplifier wattage to your cottage.
  • Feed DFB from Dani transmitters, Soundboks 3, 4 & Go speakers, other SKAA Nadja Hub speakers, as well as any of the many types of SKAA /SKAA Pro transmitters found on
  • DFB is not just for Soundboks. Use DFB to complement virtually any full-range PA speaker.  Also, any powered speaker (QSC, JBL, EV, Mackie, etc.) can be converted to SKAA wireless just by adding a pro receiver such as Streetheart by Dillinger Labs
