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.

    I bought my TW1s in 1982 and they were in "main" service until September 2003. Our cats did in the foam socks, so I'm going to try grille cloth on them. The replacement "mains" are Totem Forests. The TW1s were powered by a Hafler 220 throughout their years of use. The Hafler is on the bench right now, most of the way through a "hyper" mod involving Musical Concepts driver boards and a dual-mono power supply (96,000µF, IXYS FRED rectifier bridges, dual-secondary toroidal power transformer). It will be interesting to see how they sound with the hyper-Hafler. They were always very well balanced, neutral, "musical" speakers, though not as pinpoint precise as the better ones available today at equivalent (adjusted for inflation) cost. Has anyone explored modernizing the drivers?
    I am very happy for there are still so many people love the DCM speakers. I got a pair of Timewindow 3 recently. They are in very good condition. However, I found most people talked about TW 1a or TW 7, but not TW 3. How do you think its sound? Can it beat the normal $1,000 speakers in the current market?

    I do not have much experience, and my amplifier is a small
    Adcom 535(60W*2). According to my hearing, the bass is far from 24hz, which is publicized by DCM. Although the
    89db-sensitivity is not low, I think a more powerful amplifier will make them better. Do you have any suggestions about the amplifier?

    Thanks and enjoy your DCM speakers.
    I owned a pair of 1A models from 1981 until a home burgulary in 1991. I would love to get my hands on another set so I keep checking ebay where several pairs have been sold.

    Regarding the sound:

    After I was married in 1988, my wife made a comment about 'my' speakers. Her comment was: "the singers sound real".

    Is there any more that needs to be said?
    I purchased a pair of Time Window 3's in about '82. My cousin owned an audio store in Minneapolis. He always had someone in their trying to sell him their top end speakers. When I was ready to buy I said what's the best you have and he played the DCM's for me. Wow! So crisp and clean. Yes sounds amazing on them. I also have TF-350's to round out the sound.

    Unfortunately, my receiver is a Luxman from the same vintage and it only has 35 watts total. I think it distorts out before the Time Windows even get warmed up. I don't think I've ever heard the best they can do since that day in the store. I need to upgrade my receiver, but I'll never get rid of my speakers. The 4 combined will make for an awesome home theater (now I just have to buy a TV!).
    I love my Time Windows. They are part of my DTS System. I got them in Late 1978. They are part of the Property Rights Issue for my wife and I. I own 1 of them, she has the other.
    The problem is that the cat, hereby know as Kona, attacked and destroyed the Speaker Cover of her speaker. Is there any way to repair or replace the Cover? Help.
