Orbs certainly look very cute and unobtrusive. HOSS stands are simply stunning in appearance and design. However, I am concerned that all speakers of this type (including Gallo Diva and Nucleus) may impose sub cross over frequency that is too high to accommodate center channel dialogue properly. Proper reproduction of human voice requires a frequency response of 80 Hz to 10 kHz. A center channel speaker that is crossed over at 120 Hz or 150 Hz may degrade some of the lowest notes for bass, baritone, and tenor voices, leading to voice smearing as well as sub localization. It would appear that satellite speakers in a sub/satellite combo should be capable of reproducing sounds down to approximately 80 Hz to accommodate speech properly.
Listed below are vocal range classifications used in classical music:
Soprano (240 - 1170 Hz)
Mezzo-soprano (220 - 900 Hz)
Contralto (130 - 700 Hz)
Tenor (130 - 440 Hz)
Baritone (110 - 350 Hz)
Bass (80 - 330 Hz)http://en.wikipedia.org/wiki/Templat...l_pitch_ranges
Also worth reading is the following excellent explanation from Meyer Sound speech intelligibility papers:http://www.meyersound.com/support/pa...h/section2.htm
One of the most obvious aspects of sound system performance that affect intelligibility is frequency response. Severely band-limited systems deliver speech poorly. For instance, telephones are generally limited to a 2 kHz bandwidth, and this makes it hard to distinguish between f and s or d and t sounds.
High-quality speech systems need to cover the frequency range of about 80 Hz (for especially deep male voices) to about 10 kHz (for best reproduction of consonants, which are crucial to intelligibility). Response below 80 Hz must be eliminated to the extent possible: not only do these frequencies fall below the range of the speech signal, but also they will cause particularly destructive masking at high sound levels.
It's important, also, for the system response to be reasonably flat throughout its range. The gradual high-frequency rolloff that many reinforcement professionals favor for music applications will tend to de-emphasize consonants, which are already as much as 27 dB less loud than vowels. Likewise, prominent peaks or dips in the response can cause either self-masking or loss of consonant articulation.
Finally, the coverage of the system must be consistent throughout the intended listener area, with minimal response cancellations or off-axis dropoff in the critical high frequencies. This requirement very often dictates either a distributed loudspeaker system or carefully aimed and delayed fill speakers. Using high-Q loudspeakers will help to elevate the S/N ratio between the speech and the reverberation levels.
