The DRUM - designed and manufactured in order to reproduce the lowest
frequencies with complete tonal neutrality, an to accompany any kind of high level speaker one might select. The DRUM's unique rigidity makes it capable of reproducing even extremely
deep frequencies precisely, quickly and without any additional sounds of its own.
Many adjustment settings incorporated in the internal amplifier circuitry
make it possible to tailor the sound to virtually any listening
room.
The DRUM is also available as a passive version DRUM-P for external high
end amplifiers, controlled by home cinema processors.
