Review: DCM TimeWindow 1 Speaker


Category: Speakers

This review covers the orignal DCM Time Windows. Not the subsequent versions.

I remember the first time I heard these. Their unique shape and sound where unlike anything I had heard before. Here was a speaker that really delivered the promise. It was driven by a PS Audio Amp and PS Audio LCC PreAmp. At the time I had the Large Advents,and while those speakers were very good indeed, the Time Windows were clearly superior. The music just seemed to come alive in a way that's hard to describe. There was just a seamless transparency to them. Not overly bright or accentuated on the bass. The balance was right on. It didn't really matter what the program material was, the Time Windows clearly and with authority brought the music to life. If they had any real weakness is for some peoples taste the bass may have been on the light side. But for my taste it was as it should be. The orginals used Philips drivers using a transmission line and the cabinet construction contributed to the overall sound. In the late 70s these were not cheap at about $800.00 but were indeed worth the price of admission. I was finally able to acquire a pair of these and have them to this day. Few things one purchases in life have enduring value and the Time Windows truly are in that category. Of all the reviews I have read on these speakers not one reviewer has clearly defined the sonics of this fabulous speaker. Use all of the adjectives you want and one will still come up short in the description. Best way to describe them, if you love music and have better than average components connected to them, the Time Windows will deliver the music with a verve that will astound you.

Now these speakers are some 20 years or more in age and continue to deliver the music. And that's what this hobby is all about. DCM no longer produces the Time Windows,having opted for the HT route. This is a true shame as these speakers deserve continued production. Timeless design is just that.

Specifications:

  • Dimensions:36"H x 14 3/4"W x 11 3/4"D
  • Weight:32 Pounds
  • Power Requirements:10 Watts Minimum per channel 89 dB/watt at one meter;200 Watts Maximum
  • Impedance:5 Ohms minimum/6-8 Ohms nominal
  • Frequency Range:25Hz to 18 kHz
  • Dispersion:180 degrees horizontal/60 degrees vertical.

    Specifications do not tell the whole story,listening does. The Time Windows due to their configuration can be literally tuned to any room. That is due to their shape. This was a brilliantly executed design that has remained faithful all these years.

    Islandbird, I really appreciate your comments on DCM's distance from the back wall. I apologize for my previous comments-they were meant to extract information, such as yours. This thread has gotten those most comments on Audiogon that I've ever seen(I've only gotten about 6,000 on mine.). I agree with Ferrari's last comments(I'm actually a horn-guy, but off-axis response of the DCM's allows me to listen to music.). To help people to get the best from the original Time-Windows, I have them on maplewood, with some isonodes under them, a little further than 2 feet from the back wall(one is a corner-one has an opening). I tried those stands that elevated them about 9-inches. I hope you don't care about the bass. Actually, those stands weren't rigid, at all.
    Maybe I should e-mail DCM about this, but just moving my original DCM's less than an inch, brought about a hugh difference in the sound. I was thinking that since this has gotten the most response on Audiogon, that someone can give some pertinent information on speaker placement. I currently have my speakers a little more than two feet from the back walls(one near a corner, one near an opening). The speakers are on mapleboards(Mapleshade)with Isonodes under them. Hit me with information, please!
    Mine are now in my downstairs system about 8 feet apart and only about 8-9 inches from the back wall (measured from back of cabinet). They are still up on the walnut stands but those are also up on a quasi raised hearth that's about 14 inches above the carpeted floor. No idea why the previous owner had this configuration built to appear like a fireplace, but I think he must have had a TV in the recess and speakers to the sides out on the raised hearth. Whatever, it sounds damn good with much more bass than I hear from my upstairs system with Talon Firebirds driven by Pass X350.5! The TWs are driven by an old Threshold CAS-1 amp, which I bought at about the same time as the speakers. The imaging isn't superb being that close to the rear wall, but it sure does sound superbly musical. Even FM radio sounds right down there. Bass was never a strong suit of the original TW (which supposedly is why the TW3 was introduced), but I have plenty with them now. It's not the tightest bass, but it doesn't lag and really helps make the room seem much bigger than its 20X28X9' It's just one of those freaks of synergy. A system of my old also-rans never fails to amaze me and anyone else who hears it. My son lusts after those speakers! (over my dead body)
    Islandbird, I appreciate your response. I was hoping to move the discussion into the present realm. I know there is some benefit into elevating the DCM's, as those unstable stands that we had proved. I agree that imaging in the sweet spot is not that great, but with all the responses on this site about DCM's, I'm sure that many knowledgeable people can give information-even though it might come from their memory. You'de be suprised how much their input could provide! I would guess that my speakers are at least 10 feet apart with dissimiar backings(one's a corner, one's an open doorway). I might be able to move them closer together and get a more uniform backing?
    I've got TimeWindow 3's & 7's and they're irreplaceable. It's amazing how you can tweak their sound just by moving them 1/2" forward or back. It should also be noted that the imaging of these speakers can be fine-tuned by simply rotating each speaker by a degree or two (slight toe-in or toe-out). These speakers need to be spiked and, in the case of the smaller TWs, placed on short stands. Shot-filled Lovan Jazz or similar stands may work, though a cheaper solution may be to try cinder or concrete blocks under the speakers. Stable and acoustically inert, concrete is actually a great material in audio. If a concrete block improves performance, it may be wrapped in carpet or heavy cloth to match the room's decor. I would still use spikes or hard cones under the speakers for proper drainage of cabinet vibrations.

    BTW - On the topic of DCM re-introducing the TimeWindow, DCM had some very expensive cabinet making machinery and tools that were used to make the uniquely shaped TimeWindows & TimeFrames. When Mitek bought them out, I believe they SOLD ALL OF IT, solidifying Mitek's objective of running DCM as a value-based manufacturer. I've read some good things about the new TimeFrames; it'd be interesting to hear them.
