  • TypeIndoor/Outdoor Speakers
  • Room-filling sound from 6.5" aramid-fiber woofers and aluminum tweeters
  • Deep bass down to 25 Hz from 15" subwoofer with 250 W Class D amp
  • Three-way bass-reflex towers handle 30–180 W for dynamic playback

Bundle Composition

This package pairs two Elac DF63-BK floor speakers with a single DS153-BK powered subwoofer, creating a complete 2.1 system for music and film enthusiasts. The speakers use a three-way bass-reflex design while the subwoofer adds a dedicated 15-inch driver with built-in amplification.

Subwoofer Low-Frequency Extension

The powered subwoofer reaches down to 25 Hz thanks to its 15-inch polypropylene cone and 250 W RMS Class D amplifier, delivering authoritative bass that anchors movie effects and deep musical notes. Its sealed cabinet design ensures accurate response and straightforward integration with the towers.

System Headroom

Each tower handles up to 140 W peak and 180 W recommended amplifier power, while the subwoofer contributes 250 W RMS, giving the combination ample dynamic range for large rooms. The towers roll off at 31 Hz, so the subwoofer covers the octave below where the towers stop.

Questions about this item

How low does the 31 Hz speaker response actually reach in a typical room?

The tower speakers are rated down to 31 Hz, while the powered subwoofer extends bass output to 25 Hz, so the system reproduces deep low frequencies well below the towers' own limit.

What does the 6 Ω nominal impedance mean for amplifier matching?

At 6 Ω nominal impedance the towers draw more current than 8 Ω models, so choose an amplifier rated for 6 Ω loads and capable of delivering 30 to 180 W per channel.

How much floor space do the 43.1-inch tall towers need?

Each tower measures 7.7 inches wide by 10.6 inches deep and weighs 38.8 lbs, so allow at least that footprint plus clearance for the rear bass reflex ports.
