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 just talk to Steve for a better explanation on the TW3’s. As stated before, they are a 2-way design as far as the crossover is concerned. Just a high and low pass filter, but they can act like a 3-way based on the position of the mid level adjustment. With it set to max, you are adding resistance to the 8" driver reducing the midrange output, and increasing the midrange to the 6.5". When it is set to min, the opposite happens. In this position it acts like a 3-way. The 6.5" and 8" are both in the same chamber. There is also a factor of how the back pressure affects each drive when the midrange is adjusted. How does he come up with these ideas? I hope this helps.
    So, do the mid-range and dome tweeters cross over at the same frequency? Is that the design?
    Yeah, that's a pretty interesting design concept. It must explain some of the comments I've read over the years that the "crossover is impossibly complex" in these speakers.

    Thanks for the information.
    What do you guys think about DCM's Time Frame Evolution 200s? Are they the worthy succesors to the Time Windows as some have suggested?
    For 20 years now ím still the lucky owner of my DCM Timeframe 500's. They still sound great. Yesterday i layed my hands on a pair of TimeWindows, but the manual is gone and i'm not sure which type i bought.

    Can somebody please help to identify my second hand TimeWindow. The plate on the back of the speaker is exactly like the picture shown above, with the same number: 48104.

    Does this mean these are the (so called) originals?

    And what's the diffenrent between the original, 1, 1A ?

    Thanks,
