Om man har litt kyndighet, krefter på forsterkersiden og plass til toppmodellen fra Peter Holsteins Holfi så tror jeg ikke dette er noe dumt kjøp. Rekonet, nylakkert (så ut som en suveren finish!),diverse nyutskiftede elementer og med det som virker som en liten feil som må rettes opp, bør vel dette regnes som et kupp av en annen verden!?

4-WAY DIPOLE SPEAKER
How to make the perfect speaker unit.
First and most important parameter is to make the speaker diaphrame much harder and faster and at the same time radically improve damping of internal resonances in the diaphrame.
By adding epoxy glue to the original paper cone there and add on a "star shaped" pattern of epoxy glue at the back of the diaphragm you create a sandwich construction that not only linearice the frequency responce but also gives you a much more dynamic and vital reproduction.
By adding an extra magnet on all units, the magnet force is increased and linearised for improved speed and control.
The Woofers are made as an "open" design with no trapped air to avoid any kind of compression in the unit. The suspension of the units are reduced by simply cutting the rear suspension on the woofer units and the front suspension of the tweeter. With less suspension force the diaphrame is allowed to move much more free and with no compression of the music signal. (Free air resonance of the rebuild 8 inch woofer is as low as 11 Hz!!!)
4Th. order Linkwitz/Riley crossover network for maximum smoothness and integrity.
The crossover network has been designed to optimize all vital parameters. When using a 4 Th. order L/R crossover network almost any aspect of the speaker reproduction is far superior to low order crossover networks.
The units summarize much better off axis, the power handling is radically improved, dynamic response is much more linear, phase delay is linear and smooth, and overall frequency response can easily be controlled without applying extra components in network.
True ground connection:
The Sonair loudspeaker implement several new technologies in loudspeaker design. Most special is the extra terminal for connecting true ground to the speaker chassis. By connecting the speaker chassis to a ground spear or the mains ground connection then the fluctuations in magnet force caused by the music signal is simply short-circuited. By sound quality details and clarity in soundstage is radically improved and by measuring high order distortion is reduced as much as 20 dB.
All capacitors improves in sound quality by having a pre biased DC-voltage connected. The chemical process within the capacitor is then optimized providing lower distortion from the capacitor. Added to the advanced crossover PCB inside the Sonair speaker is a circuitry taking some of the music signal and converting it to a DC-voltage then feeding all capacitors in circuitry with the sound improving pre-biasing DC-voltage.
Unique bass system of the SONAIR.
To provide full output power below 30 Hz, Holfi has developed a special bass system making the two woofers actually drive each other by the induced voice coil voltage from the music signal. As such the woofers increase their movements not only to go down deeper in frequency response, but also to increase sensitivity for the total system.
Effortless reproduction from the SONAIR.
As it is absolutely vital to avoid any kind of compression in the speaker system you simply have to make a dipole design with all units free vented on the rear of the speaker. We have combined this with a bass-reflex system, to make a correct balance in the lower octaves.
First having experienced the total lack of compression from the SONAIR speaker and the effortless way of reproducing all kinds of music you hardly can live without it.
Add to this a perfect balanced tonal control and a power handling only limited by the extension of the woofer movements.
