Alright, since I'm seeing quite a bit of back and forth on these I'd thought I would chime in with my experience. As mentioned earlier I have already bought a pair of D15s. I think they sounded great. Coming from a pure Klipsch system prior I was delighted to hear how silky smooth these are. The midrange is definitely a step up. I ordered the D17s from his deal and received them on the 28th. I wasn't expecting a huge difference as compared to the D15s and there is not. However the difference I do hear is a plus. The D17s, unsurprisingly, have better bottom end. I think that translates into a bit warmer speaker overall which I seem to like. I love bass and have dual svs sb3000s. I haven't really had the subs on with the D17s yet as I'm wanting to fully break them in. I will say I can understand how some people might be underwhelmed listening to these at first especially compared to Klipsch. Klipsch sound is definitely in your face which I also like but these D15s and D17s just sound more grown up. I noticed that at low volumes the sound is almost boiler plate. Not bad by any means but these things can handle power and when I crank them up to about midway to the max volume I really like they seem to wake up. I'd compare it to driving a civic type R cruising at 40 mph. It's fine nothing wrong with it but not particularly exciting. Step on the gas, ie add some volume and it's like whoa! These really wake up. They are buttery smooth flat all the way up to max listening volumes and they have that great sound as you add volume that gives the impression they aren't breaking a sweat at all and can go much louder. Klipsch does the same in that regard, I think all good speakers do, but there's just something really pleasant with these as the volume goes up. Anyway just my 2c. Happy to answer any questions to.

I have the D15s and can only echo SpearmintRhino's positive experience, although I might be coming from the complete opposite end of the spectrum in terms of speaker preferences. My main speakers are vintage Spendors, and I have never liked bright speakers. I was a little hesitant to purchase these speakers because some reviews suggested they are slightly bright on top. I know that not all bright speakers sound hard and brittle, but since I love listening to choral music, an accurate and life-like presentation of the human voice is my top priority. Some of you may agree that, more often than not, even speakers that measure well can fail to reproduce the natural timbre of a voice. In my experience, the D15s produce a wonderfully balanced and natural sound in vocal reproduction. They also do well with acoustic instruments, so if you're a fan of classical music and jazz, I would highly recommend these. I find them to be neutral and transparent to the characteristics of your source and amplification. Yet, at the same time, they have the ability to make music very engaging, enjoyable, and pleasant to listen to, unlike some neutral speakers that can sound dry, analytical, and constrained. As expected, speaker placement had a significant impact on the overall tonal characteristics. I have set up the pair in a semi-open space with at least 8 feet from the wall boundaries in all directions. The midrange and bass are still full-bodied with a wide-open soundstage and precise imaging. I am really enjoying these speakers and wanted to share my experience with you, especially if you're considering them for two-channel music listening.

I'm in for a black pair. I already have the D15s from a few weeks back. They are properly broken in and they sound so so good paired with dual svs sd3000s. I'm not expecting the D17s to big significantly better than the D15s But I'll be moving the D15s to the rear replacing a pair of Klipsch 820f. The fronts I had prior were the Klipsch 280rf. I like the Klipsch but these are so silky smooth I love them! Hats off to all the nay Sayers. They helped keep demand low on these so the price kept going down. Such an awesome slickdeal!

Quote from racker15 :
It's fascinating to see so many commentors state that these are not good sound quality despite 3rd party measurements and even state that they are clearly a downgrade from speakers like Borea BR02/03 (!!) and JBL 530 (sure, to maybe 60-80 hz). I guess this really shows that marketing / media / perception and a preferred "sound signature" is a huge part of how well a speaker sells, not just a solid neutral sound. Poor Definitive
while they are stating as long as you consider them as 300 each quality while br03 is 299 pair lol. I am really confused on ppl's comments. and it stopped me from buying them. I feel sad lol.

It's a simple trick to figure it out but I don't want to disclose so that Adorama doesn't change their UI.

I'm thinking we'll get these at $600, but who knows...

Looks like they keep changing the link, which is interesting...
Thanks for the tip, I figured it out Wink

I figured it out too. it is around 953 for white. cant decide to buy one or not as most ppl suggest me to get subwoofer instead of these to build on the current 2.0 system.

Would these really not work well with AIYIMA A07 TPA3255 Power Amplifier 300Wx2 HiFi Class D? Just feels like I would need another big amp, then another $200 for a sub... it all starts with just swapping a set of speakers out..

If that amount is legit 300 watts per channel there's likely no commercially available speakers it can't power.

It's 300watts at 4ohms though so prob like 150 at 6-8ohms at best. it's a class d though and one guy said it sounded lifeless with one. not sure if his had lower power though.

At worst you'll have 48watts of power [audiosciencereview.com] if you have the 32V 5A power supply and the worst case of 8 ohm (these speakers are "rated 8 ohm" but probably 6 ohm). With the D17's sensitivity of 87 dB, thats gonna give you 97 dB at 10 feet away [mehlau.net] from a SINGLE SPEAKER. Is that enough for full-out rock music, probably not. But in this budget-realm (e.g. powering $600-$700 speakers) that will be fine IMHO?

I just watched a movie in the theater and at the loudest point where kids were covering their ears I measured 98 dB.

But also yes, get a sub. Smilie

It makes sense why they still have more than a thousand pairs of these left!
I tried the D15 and returned it, luckily it had some damage so no shipping costs.
Just installed D17 yesterday and while sound is better, its not worth even $700. I have SVS subs so bass is not an issue. It's the mids and highs that are lacking. My JBL 570 sounds better and I measured with REW software. Yes I can use extra smoothing to make the curve look flat like many paid pro reviews do but you will know when you listen to these.

I do YouTube reviews so these buys and returns happen and I incur return costs. I was hoping to keep these D17s but really lack audio quality. Build Quality is good though but audio is more important which D17 lacks.

If you have a Sub, my opinion is this is a no buy. And if you want good all range audio, you need a Sub. At this price point, I know you could have gotten JBL 580, Martin logans at best buy which are out of stock.

Right, at 85.5 db sensitivity a pair of them will only hit 108db peak at 100W peak amplifier power. Barely beating theater reference levels certainly wouldn't be enough!

On a side note I run 86db sensitivity speakers at 100W and at max volume they make my ears bleed, but only barely.
I was wondering the same thing... How loud is enough for some people. I have an 80W/channel receiver and the speakers get plenty loud at 70% of max volume.

Maybe your room setup, these things are really sensitive to placement? I bought the D15 for $500 and think they sound great. My friend has Kef R7 towers, and I like those more, but at this price point I can't complain. I don't like bright speakers though, I like more neutral mellow sound, so I guess it's just subjective.

We all have to remember that our "perceived" sense of loudness is logarithmic so doubling the power only has a small change in perceived volume. It's nature's way of giving us HUGE sensitivity and dynamic range in our sensory system.

I'm assuming you're measuring in a room? The D15s were measured by audioholics outside. Its a bold to assume the pro reviews are done by people who are paid. Evidence? What's your YouTube channel? Curious about your process.
