Part of what makes the D15 excel at music reproduction is its unique tweeter design. Each speaker's 1" aluminum dome tweeter is offset from the midrange and bass drivers by half an inch. This helps create a wide listening "sweet spot," along with a lifelike soundstage.
The tweeters also benefit from Def Tech's 20/20 Wave Alignment Lens™ technology, which helps ensure ultra-clear highs that sound good no matter where you're sitting.
Each D15 sports two 5-1/4" Balanced Double Surround System (BDSS) carbon fiber woofers for accurate, punchy bass. Dual side-firing 8" side-firing passive radiators in each cabinet helps increase bass extension.
Love listening from different spots around your room? Definitive Technology employs a Linear Response Waveguide™ on each 5-1/4" midrange driver for improved off-axis imaging compared to traditional driver designs.
All of this design technology adds up to terrific sound — provided that you have enough power to properly drive them. The D15s have a nominal impedance of 8 ohms, and with an 85.5 dB sensitivity rating, they're real "gas-guzzlers." I highly recommend a high-output power amp or integrated amp to drive these speakers.
Each tower comes equipped with two pairs of speaker inputs for bi-amping or bi-wiring
