Just "off the cuff"...
1) Made in USA from USA sourced content whenever possible ( I believe every component is USA sourced except the metal grill pins).
2) Sealed design
3) High Efficiency and an easy/stable load to power.(impedance)
The ability to play at very loud levels without the need for expensive amplification. The benefits here are two fold. First, even an inexpensive ($300?) receiver will be able to power these speakers to very loud levels in all but the largest of room environments. Second, even at moderate output levels there are still audible benefits. Subtle details and nuances of the program material will be more audible. The term "micro dynamics" is often used to describe this phenomenon.
4) Bass extension down to 60-70hz. This would ensure plenty of frequency overlap with subwoofers with all speakers set to 80hz(or even a bit lower) We recommend 60hz as the lowest crossover point with these designs although in smaller rooms you may see nice output down to the 50-55hz range.
At this point I believe everyone understands the benefits of dedicated subwoofers to handle the bass in home audio. Not only will a quality subwoofer offer more headroom it will also provide more accurate bass reproduction in most cases because the subwoofer can be placed in the room to maximize bass performance. The full range speakers need to be placed in very specific locations because of imaging and directional cues. These spots are rarely the best for bass reproduction.
5) Accurate sound reproduction verified with both subjective listening impressions as well as objective/measured performance.
Obviously, accurate sound reproduction is the key to any speaker design. While listening sessions play an important role in the process without high resolution measurements any speaker design will be prone to mistakes. Simply put, our ears are no where near as resolving as a quality measurement rig. When you combine all of the necessary acoustical measurements with an endless amount of crossover variations it should surprise no one that a quality speaker design will take many, many months of hard work.
6) In house crossover development. While using an off the shelf crossover from an outside source can get you "75%" of the way there while saving MONTHS of development time....you will never be able to really optimize any design in this manner. The crossover has been called the "heart" of any speaker design by many of the most respected designers in the industry and they will get no argument from me.
7) Reasonably sized with dimensions and weight that would work in the majority of room environments.
8) Aesthetics that match our current subwoofers.
9) Fairly priced for the performance, build quality, and most importantly customer support. Let's face it, it would be easy to pick one of these to excel at. Two, more difficult but not impossible by any measure. But all three can take a tremendous amount of time and effort.
