 Anvendelse af SUB-10 C med indlysende fordele:

C= custom  SUB-10 C er en kompakt konstruktion med anti-vibrations-system, der er velegnet til individuel indbygning bl.a. i reolsystemer.

Lydgengivelse til film med lydeffekter indeholdende frekvenser ned til det subsoniske
område gengives virkelighedsnær og dynamisk.
 
Lydgengivelse til musik, hvor selv meget dybe toner f.eks. fra orgler, kontrabas,               stortrummer o.l. gengives naturligt.
 
Højner lydkvaliteten i satellithøjttalere (kompakte tovejshøjttalere), idet SUB-10 C overtager gengivelsen af basområdet, reduceres intermodulations-forvrængning væsentlig  i det vigtige mellemtoneområde. Gengivelsen af f.eks, stemmer bliver optimeret.

Technique
 
Woofer-unit ideal for placement in furniture.

The boxer-configuration with two drivers ensure reducing cabinet vibrations and resonances with more than 90 %.

At the same time the two drivers with two very powerful “motors” working together with the sealed twin-cavities with slot loaded output. The result is a very accurate impulse response.

Resistive slot loaded assures smooth frequency response. Slot Loaded is a superior way of smoothing and extending the low bass of the bass-unit.

It is a tried-and-true design whose benefits are simplicity, better transient response, extended low bass, aperiodicity or no "bump" in the bass response and better power handling than a tuned-port design.

Efficiency lies halfway between a tuned port and an infinite baffle, and the impedance the amplifier "sees" is smoother than either of the other designs.
