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.

    Called the number for DCM listed elsewhere in these postings as I am also looking to replace the foam covers on my TW 1's. They no longer directly supply replacements or the material, but did direct me to McMaster.com (as mentioned elsewhere on this forum). The correct part number for the filter foam that can be ordered on their site is 2195K52 (1/4" charcoal colored foam with 30 pores per inch (ppi)). Telephone number for McMaster is 404-346-7000. Hope this is helpful.
    If someone wants to order a roll of this foam from McMaster-Carr( $46.99 for a 10 ft. roll) I'll buy a few feet from them as I need to wrap some older Rauna Tyr II monitors. Thanks, Sherod
    I haven't read all the responses here, but I recently got the okay to tighten the drivers from DCM.
    Does anybody know the tweeter/woofer crossover frequency in the Time Windows. I'm not sure whether they are TW1's or TW2's. The serial numbers are 360..
    Thanks for any help,
    Pete
    I'm not sure of the crossover frequencies(and, hence, I cannot help you identify your particular version.), but I have always suspected that they were different from each other, let's say on just one speaker. I, myself, wonder what the chalkmarks mean.
