Review Summary

D15 are great update. Speakers are good on the highs and great on the mid range. Able to turn the crossover on my sub down, since the D15 have passive subs. The combo with the Def Tech sub is outstanding for lows and mids, highs could be better. A quality source material is ALWAYS as important as speakers and amplification.

Incredible clarity with these speakers. No muddyness in the crossover and surprisingly deep bass. I often shut my sub off just to hear these on their own.

Fantastic floor standing speakers. They sound great. And, the build quality is fantastic. Oh, and they look beautiful. Well worth the $3000 entry point.

Def Tech Does It Again! After a few weeks of playing set up placement and break in these speakers shine! Get these while they last! What a deal!

Replaced Infinity Beta 50s, these have much better base even when they have much smaller enclosure. I did not find the lower 85.5 db sensitivity an issue for the 18x18 room when using a decent AVR. More linearity, clean mid-base which I was missing earlier. Imaging is excellent, extremely good highs, really living up to the $3000 plus a pair in sound, looks and build quality.

This is the second day that I have had wonderful speakers. I was a little hesitant at first to order them since I have a pair of Def Tech BP8040ST that I have had for a half dozen years or more, and the powered subs in both speakers took a dump. I figured that getting the D15's without the subs would be pretty safe, so I stepped up to the plate. I sure am glad I did it, they are beautiful. From the way they were packaged and how the base and parts came in a presentation box. When I finally got the speakers out of the box I said to myself, I hope they sound as good as they look. Needless to say I am not the least bit disappointed. I realize that food, woman and wine are all subjective to the individual, so what's good for the goose is not necessarily good for the gander. Buy them before there gone.

My wife and I both love the DN15 speakers. We are hearing more instruments and backing vocals on our favorite songs. Everything Sounds Better! Music like we never heard before.

Replaced Infinity Beta 50s, these have much better base even when they have much smaller enclosure. I did not find the lower 85.5 db sensitivity an issue for the 18x18 room when using a decent AVR.

Tall, slim speakers are certainly in fashion, and it's hard to imagine many slimmer than Definitive Technology's new Demand Series D15 towers. Despite housing three 5.25-inch drivers (two carbon fiber woofers and a polypropylene midrange), a 1-inch aluminum dome tweeter, and not one but two 8-inch side-firing passive radiators, the D15 measures just 6.5 inches wide and thus indeed requires its bolt-on aluminum bottom plinth to achieve stability.
Def Tech has always balanced serious value with serious performance, and the Demand series clearly maintains the tradition. But while the firm's top-range calling card has from inception been bipolar designs, with both forward- and rearward-radiating drivers and on-board powered "subwoofer" bass sections, the Demand series breaks rank, placing conventional, monopole (forward-only), fully passive designs at the top, price-wise at least, of Def Tech's offerings for the first time.
The D15 is the second of two Demand series tower designs; the slightly larger and costlier D17 employs 6.5-inch drivers and 10-inch passive radiators yet specifies bass extension only a few Hertz lower with a modest 2 dB gain in sensitivity. To fill out our test system, the company included the Demand D5C center-channel unit and a pair of D9s, the middle of three bookshelf speaker offerings, for the surround channels, all in the gloss-white lacquer that is one of two finish options (piano black's the other).
Tall, slim towers producing smooth octave-to-octave balance across the house, resonance-free response; broad, gradually falling-off dispersion; and smoothly contoured, generally similar off-axis responses.
These once-rare virtues are encountered ever more frequently, thanks at least in part to the computer-aided engineering, modeling, and measurement that have become common practice. This leads in turn to what many might characterize as a boring sameness of result. Boring, that is, only in the sense that most airline flights, thanks to aviation's own advanced technologies, produce similar results: reliably smooth, crash-free trips.
The Demand Series D15 towers, in short, are very fine reproducers, and in any room they sound considerably fuller-range than their fairly modest 48 Hz (-3 dB) bass extension spec suggested. The track "Royals" (24-bit/48kHz FLAC, Qobuz) by Lorde opens with a loose orchestral bass-drum strike (real or synthesized—I can no longer tell these days), with fundamentals probably around 40 Hz or so and dipping lower on the decay that obligingly repeats every downbeat.
Experience the stylish and high-quality Demand D15 Floorstanding Speaker, Right, Piano Black, a product of Definitive Technology's commitment to superior audio equipment. This powerful and sophisticated speaker is designed to deliver a spacious and expansive sound, transforming your audio experience with its formidable lows and smooth high-frequency reproduction.
The D15 Tower Speaker is engineered with a unique 3-way driver configuration, featuring a 1" annealed aluminum dome tweeter, a 5.25" BDSS midrange woofer, and dual 5.25" carbon fiber bass drivers. This is further enhanced by dual 8" side-firing passive radiators, ensuring a full-range, room-filling sonic performance that immerses you in sound.
Definitive Technology's proprietary drivers are meticulously designed to deliver a balanced, precise, and musical sound. The laterally offset 1" Aluminum Dome Tweeter, coupled with our 20/20 Wave Alignment Lens, minimizes wave cancellations off the front baffle, delivering a precise center stereo image and clear, detailed high-frequency performance.
The D15's 5.25" patented Balanced Double Surround System (BDSS) mid/bass driver provides superior midrange detail and punchier bass compared to other drivers of similar size. The custom-woven carbon fiber woofers ensure deep, evenly extended bass notes while preventing distortion-causing cone deformation.
Experience the visceral bass response from the twin integrated 8" passive bass radiators in each speaker, designed for superior low-end extension. The audiophile-quality crossovers, built with premium parts, manage frequencies meticulously for clean and crystalline treble, refined and articulate midrange, and linear, low-distortion bass.
The patented Linear Response Waveguide extends both on-axis and off-axis frequency dispersion, ensuring natural midrange timbre and precise imaging. The D15 Tower Speaker's attention to detail extends beyond sound, with a modern aesthetic featuring extruded aluminum front baffles and a bead-blasted finish. Each speaker is sanded and painted with five layers of premium gloss paint, then buffed to a near-mirror finish, making it a stylish addition to any home decor.
In summary, the Demand D15 Floorstanding Speaker, Right, Piano Black offers a perfect blend of style, power, and sophistication, making it an ideal choice for true audiophiles.
