[/FONT][FONT=&quot]An example of integral isodynamic system, with a pair of MG 2.7 Magneplanar[/FONT][FONT=&quot]

[/FONT][FONT=&quot]This loudspeaker requires a monophonic low power amplifier and an active filter. (μαλλον αυτο λεει ....http://www.borsaudio.com/Borsaudio/FAK001.html )
[/FONT][FONT=&quot]This filter will manage the left and right input signals (cinch plugs), and will provide three cinch outputs:[/FONT]
  • [FONT=&quot]Two outputs: left and right, high pass filtered at 110 Hz 24 dB / oct.[/FONT]
  • [FONT=&quot]A low frequency output adding left and right signals, low pass filtered at 110 Hz at 24 dB/oct.[/FONT]
[FONT=&quot]A volume control on the three channels will be available at the front, in order to balance the left, right and planar loudspeaker output volumes.[/FONT]

[FONT=&quot]Lastly, a bypass will allow to switch instantaneously the system either in 2.0 mode (classic stereophonic system with no low frequency planar loudspeaker, and no left or right channel filtering) or in 2.1 mode (with low frequency planar loudspeaker), with an aim to make instantaneous comparisons ‛with’ vs ‛without’ low frequency planar loudspeaker. This is a very interesting feature allowing an easy and immediate way of realising the gain brought by the isodynamic low frequency panel.




[/FONT][FONT=&quot]Για ριξτε μια ματια, ισως εχει ενδιαφερον....

Ας μας πει και καποιος πως δουλευει αυτο το active filter γιατι δεν καταλαβα και καλα.
Παντως τα διαγραμματα απ'οσο τα καταλαβα ειναι εντυπωσιακα.....

Α, και δεν ειναι και πολυυυ ακριβο :a0210:

Αυτο αναλαμβανει τις συχνοτητες κατω απο τα 110 hz?

[FONT=&quot]NB: these [/FONT][FONT=&quot]curves are produced with a CLIO system of 24 points per octave. The curve is made in proximity in order to minimize the room resonances. [/FONT][FONT=&quot]NB: [/FONT][FONT=&quot]CLIO limits the curves to 10 Hz but energy is present in proximity from 8 Hz at -2dB

[FONT=&quot]With levels of effective power of about 5 to 7 Watts, the sound levels reached are very impressive and generate a completely realistic listening



Υποθετω οτι στη μετρηση χρησιμοποιησε και το active filter, οποτε αν εκανε το στησιμο by το δικο του book, κατω απο τους 110 , επαιζε αυτο !!
