VTC Type
The 95 and 81 are intended to be used in biamp systems where the low extremity of frequencies is not needed. These two designs were made with the BD-Design Oris in mind where the Lowther driven front-horn produces frequencies of 160Hz and up only. The 60Hz fall off point at -3dB ideally suits the horn response and allows for more energy to be conserved for the frequencies that ARE heard, this enables you to design amps with lower power output.
A lower
primary DC resistance than the standard range of products.This gives the sound a
more "open" character allowing for more transparancy and detail.
All output transformers are wound with 6 ohm secondary winding, not three
different values. We feel this further inproves sound quality by removing any
unused "wire" that is bungling along with the output. Other secondary
values are also possible (4, 8, 12 or 16 ohms)
