The DRUM - developed and constructed in order to reproduce the lowest
frequency sector neutrally and with any kind of high level. On account
of its construction the DRUM is capable of reproducing even extremely
deep frequencies precisely, quick and without any own sound.
Many adjusting possibilities, in the installed amplifier,
make also possible a perfect adjustment to the corresponding listening
room. Also available as passive version DRUM-P for external high
end amplifiers, controlled by home cinema processors.
