The 100M
Hybrid Minimonitor-Active Bandpass Subwoofer SystemInspiration and Design Goals Over the years we have received many accolades for the performance of our 20M and 15EXP Armada System. For example, Kurt Lundvall, of Lundvall Mastering, one of the best audio mastering engineers, had this to say: "I purchased a complete 20M Armada system over a year ago which I use daily for audio mastering. This system has simply allowed me to get closer to creating a perfectly balanced master than I ever thought possible."

20M-15EXP Armada System
In designing the 100M, our goal was to design a compact loudspeaker that could replicate the performance of the combination of a pair of our 20M monitors, a pair of our 24 inch Sandbags stands, and a pair of our 15EXP subwoofers. We have integrated each of these elements so well into the design of the 100M, that the result is an efficient design that may well be greater than the sum of it's component parts.
It was not enough for us to match the performance of the 20M and 15EXP Armada System. As we designed the 100M we were mindful of issues and needs that anyone designing a contemporary loudspeaker should address. For example, whereas the 15EXP is 15 inches deep, the 100M is just 12.5 inches deep, so that if it is used next to a flat screen TV it will not block viewing angles off to the side. We also manufacture the 100M with certified "green" non-toxic formaldehyde-free lumber, and non-toxic glues and paints. "Green" manufacturing is certainly more challenging, time consuming, and expensive. But by using innovative cost-cutting manufacturing techniques we are able to offer the 100M at a fraction of the cost of comparable loudspeakers such as the Thiel CS3.7 and the KEF Reference 205/2 Loudspeakers.

The 100M Ambient Sound Loudspeaker The 100M is a time coherent, point source, first order, two-way acoustic suspension loudspeaker with a built in full-featured 200 watt, 10 inch treated paper cone bandpass subwoofer that delivers a stunning linear 27 Hz to 20,000Hz plus and minus 3.5 dB performance. It is designed to reproduce music with superior musicality, coherence, spatial presentation, dynamics, speed and tonality. It captures every nuance of music to accurately convey the emotionalism and spiritualism of the performance.
The cabinet of the 100M features an innovative new design that is only 12.5 inch deep at the base and tapers to 11.5 inches at the top, with beveled edges that softens its looks as well as prevent refraction. The small foot print (12.5 X 12 inches) and good looks accent to any decor. It is one of the most powerful compact loudspeakers available and its 12.5 inch depth allows it to be used close to flat panel TVs without blocking the viewing angle.
In the tradition of breakthrough products, the 100M skillfully blends performance characteristics that were previously thought to be contradictory: It is revealing, but musical; dynamic, but refined. It is obvious, but enigmatic. It has to be experienced to be believed.
