Hello my fellow audiophiles. I havent been here in a few months. But I have excellent news. I acquired a pair of Velodyne DF-661 speakers from an old lady for only $100! I guess her husband passed and she knew nothing about the speakers other than hey sounded "wonderful". Indeed they do. I will write a full review on them soon. But keep in mind, my ears were virgins to $2400 speakers.

I also bought a Paradigm PDR-10 subwoofer for $100, and it rips my old Bose a new one. I ended up giving the people that bought my Klipsch RB-5 (that I sold for $100 the peice of crap "bass module".

Im back.

edit: excuse the double posting. I originally thought I was posting in the general section when I accidently posted in the loudspeakers section.

Sold the Bose for a profit, good for you:). If I remember you bought the module for $20. I guess it was worth buying it in the first place;).

Yes, $20. The Bose deffinitly took a beating and supplied me with mediocre bass enjoyment. Now Im just blown away by my Paradigm PDR-10.

The Velodynes however, those are something special.

Ive been trying to find more imformation about these Velodyne. I guess they debuted in 1994 as their first ever loudspeaker. It initially got bad reviews because of manufacturing faults and compromises in box design and crossovers in exchange for ultra low distortion. Additionally, there were some quality control problems with some of the midrange and woofer drivers in the begining. I actually ended up with a faulty woofer on one of the monitors. Under heavy low frequency bass, the woofer will make a clicking/whistling noise, almost sounding like a whistling port. The driver is not blown, but it does make this annoying noise with certain songs. Im thinking about taking the woofer out and trying to fix it, but I wouldent know what it is.

Also, I cant for the life of me find a frequency response graph for these. It sounds pretty damn flat though. When referring to the sonic circle, the speaker has a very precise sound signature, which is exactly my flavor.

And now, on to the review....

Ok, so Ive had my new Velodyne DF-661 and Paradigm PDR-10 combo for about a month or so, so Ive come to know the setup pretty well. Everything is driven by a simple Yamaha 100 watt/ch stereo receiver. I have a high pass filter on my computer set at 65hz, and that made the bass woofer on the speakers stop making noises caused by subsonic frequencies. My sub is set to 70hz and the volume is about 30%. My room is 10.2ft x11.1ft. The speakers are positioned according to the golden ratio measurments, and the sub is near the front left corner. Listening material varies from electronic music, jazz, metal, rap, and classic rock.

The first thing I noticed plugging in the DF-661 was how clear they sounded. With that ultra low distortion, I could hear all the details without any audible grain, hiss, anything. Just pure music. The resolution of the details was also very good. The attack and decay response was very fast. Running a 20-20k sweep test reveals the midbass is slightly recessed in some frequencies compared to the mids and highs. The midrange and tweeter integrate perfectly and the extension sounded damn flat up to my hearing limit.

Treble was crisp and sweet, especially compared to my old Klipsch's harsh horn in my old, perfectly square room. The tweeter is also good at high frequency stereo imaging. The treble extension is similar to my klipsch, except a smoother response and integration with mids/woofer. Like the Klipsch, the midrange and treble are quite aparant and "forward" sounding. The detail of the midrange and treble is very excellent. The 6" midrange driver has very fast impulse response and the detail is just great. The midrange seems slightly more forward then treble.

The best way to describe the bass is "tight". Bass guitar sounds natrual. The woofer has nice warmth and body, as well as a "clean" impact. But the amount of impact is not very much. The extension goes down to a modest 60hz, so a sub is deffinitly a must. With bass heavy music, the bass is heard clearly, just not impactfully. My Paradigm sub really helps out with this, but my midbass still suffers a little. Overall, the bass is the weakest driver out of the 3, but integrates exceptionally.

Now on to the soundstage and imaging. As I said before, these speakers are similar to my klipsch in that they are forward sounding. The voice on the velodyne is more in the middle and natrual sounding. The Klipsch seemed to emphasize the voice a little too much. The soundstage overall is pretty small. It isnt much if any bigger than the Klipsch were. But the directional imaging is much more defined. I will hear sounds zip and curve very precicly across the soundstage. The speakers position the sounds very well, just not really large like say a Bose 901. I wish it were a bit larger, because the small stage makes some of the insruments sound too close together.

This is my main review. I will post more details as well as pictures shortly.

Welcome back EYEdROP0.

Your review got me to google those speakers. Sounds like you got quite a deal and I'm glad you're enjoying them. It's interesting that they are a 3 way design where one of those 6" drivers is the woofer and the other is a mid. 6 ohm with an 88dB efficiency rating. Not exactly your run of the mill speaker. Those things went for serious bucks back in the day.

I don't know about anybody else but pic's really do it for me.

Thanks. :)

I met one of the guys who actually helped design those speakers (Velodyne is local). I've never heard them myself, but he says they are amazing. He has the cover where they received a great review in Stereophile mag framed in his cube. Nice guy.

One of the product support guys for Velodyne lives really close to me. I called him up regarding general info about the speakers. They are very rare and parts are pretty much non-existent. The sub and midrange drivers were made by hand and computer lathed. The lathing machines have since then been destroyed. He told me there were 2 versions of the DF-661. The more beta 1 screw per corner and the 2 screw version (which is mine, manufactured 1995). One good peice of advice he told me is to literally flip the box upside down so that the bass woofer is on the top. This keeps 500hz from reflecting off the floor.

2 things led to the demise of the DF. First, the stereophile reveiw was pretty bad compared to other speakers in the price range. The Velodyne guy said the reviewer was sitting way too close to the speakers and the room had many reflections. Basically, it didnt get a fair review at first and the head Velodyne dude got really upset. So they had an acoustical engineer design a really good crossover that sounded just awesome. They ended up spending too much on the project and the cost to keep making the speakers was too much. Basically, they would have had to double the retail price to keep making these.

The great thing is, he is sending me via postage a 21 page document by this acoustical engineer explaining all the modifications to the crossover, as well as other info. I am too exited.

Ive never dealt with such modifications, but Im going to have a friend help me, as well as other audioholics. I have no idea what Im getting myself into.

Hi EYEdROP0,

I'm looking for a replacement midrange for my lovely 1993 DF 661's. I've tried PM'ing you, but this forum won't let me PM until I post 5 times. Argh. I notice you've got some broken 661's and I'll happily make you a competitive offer for one of the drivers. Please drop me a note at mucci at eecs dot utk dot edu Thanks!

Phil
