Fred, welcome to beoworld, and congratulations on your stunning new speakers!

What do you mean when you say that some functions are not implemented yet. Has the automatic room compensation really not been implemented yet? π
The BL90 will never do 'automatic' room compensation in the BL5 sense, as the aim is to compensate at specific listening positions / zones rather than measuring how the room sounds next to the speaker. Ultimately this will involve (the installer) connecting the microphone to the speaker and performing compensation measurements in each of the listening positions, and the user will then be able to select between these depending on where they are sitting, but for now the calibration is performed in the main listening position only with the aid of a reference microphone, a laptop, and some additional hardware, with the resultant calibration profiles then being uploaded to the BL90s.
Having heard the BL90s prior to this calibration having been performed, hearing how good they sound and in particular how effective the narrow beam mode was at reducing reflected sounds (thus eliminating much of the 'room effect', as well as producing such a detailed sound stage - especially in terms of sounds appearing to emanate from far in front of or behind the virtual line drawn between the two speakers), I was sceptical that things would be improved much further by the calibration process.
Boy was I wrong! the calibration curves showed we had a peak variation of around 6 or 7dB from flat response centred at just above 100Hz, once the calibration was completed there was a noticeable improvement in how tight the bass response sounded.
I have neither the space nor the budget for a pair of BL90s, but I do feel lucky to be able to listen to them frequently when visiting the store. There is however one downside - they make every other speaker sound somewhat inferior in comparison!
