Although the Blue uses the same highly efficient, tuned port system as all other Burhoe speakers, it is the least expensive unit to provide the benefits of three active drivers.
Because one of those drivers is the revolutionary Burhoe biradial tweeter, the Blue can deliver frequencies up to 26,000 Hz. An inverted-dome midrange driver is used to enhance the flatness of the Blue's over-all frequency response. Finally, a ten inch woofer, working with an optimized tuned port, delivers low frequencies right down to 30 Hz.
A further enhancement to the flexibility of the Blue Burhoe are the dual tweeter controls that allow the listener to adjust the amount of overlap and, therefore, the amount of dispersion. For more directed sound and enhanced stereo effects, turn up both tweeters to increase the amount of overlap. For wider dispersion, just turn down either tweeter. By changing the dispersion characteristics of the Blue, you can bring voices up front and increase stereo imaging. You can also get crisper highs by turning on the high frequency switch.
It's simple to tune the Blue perfectly to any room and to all types of music material. That means that although the Blue is designed to deliver the flatness demanded by classical music lovers it can also meet the equally demanding requirements of rock music fans.
For superbly uncompromising sound and all around performance in any listening environment, it's hard to beat the Blue Burhoe.
