Digital Frequency Crossover with Pre+Power Amplifier

In respect to all functions and settings of Hi-Fi Speakers one should ask the following:
1. Which details do I hear and how can changes be evaluated?
2. What requirements for improvement are necessary in hardware and software and at what does it cost?
The electronic signal differentiation IN-OUT has been minimal for some years now. Even mediocre mass-produced electronics offer a hundred times better specifications than the the best speakers. This can be seen and varified on professional square wave oscilloscopes and other test equipment; therefore, it would make little sense for the average money earner to spend large amounts of money for marginal changes which would result only in minimal, if any, improvement to even the best of speakers.
The DSP-6 has been designed and produced to provide significant improvement of speakers tuning and adjustment for the audio enthusiast and even the semi-professional. It offers simple use of operation and provides precise fine tuning.
The following features and applications are available. The DSP-6 is designed to:
-specifically correct the frequency band of passive speakers
-allow configuration of one, two and three-way speaker systems
-correct room resonant modes, standing waves and time alignment
Specifically, correction of high quality full range speakers with the use of the DSP-6 results in a distinct audible improvement when compared with a high quality passive crossover network. Those who have already been engaged building a passive crossover network are well aware of the complexity,difficulty and limits imposed on such a project. Many will also have boxes filled with various components such as capacitators, resistors and other components, likely never to be used again.
The DSP-6 has been designed and produced to provide optimal adjustment of any speaker, achieving an immediate discernible audible difference without wasted experiments, time and high cost.
The audio enthusiast obtains a high quality, professionally designed and built digital crossover amplifier with the DSP-6.
The DSP-6 will marginally change the signal path of other components such as the CD player, amplifier,etc.; however, these aberations are so small that the benefits gained by use of the DSP-6 far outweigh these changes. In this regard, the debate amongst audiophiles on this subject is basically academic. Fact remains that the professionally designed high quality digital DSP-6 crossover-amplifier greatly out-performs any passive crossover network. High quality passive speakers will substantially gain from the conversion to digital operation and  adjustment flexibility offered by the DSP-6.
