The passive radiator SD315-PR is useful accessory to enjoy a more powerful and richer sound in the low frequencies. A useful feature for extending the bandwidth of a pregnant and give a boost to your speakers to venture more readily in the bass.This model large diameter (12 inches / 30 cm) and excursion rates make it an ideal and economical solution to strengthen a subwoofer. Its size allows it to operate in simple installation (1 subwoofer radiator 1) with a loudspeaker of medium size.
It may also (and especially) use this radiator in more complex installations (several radiators 1 subwoofer). The SD315-PR-12 is an excellent candidate for this approach because its size and excursion rates allow much more massive facilities (2 radiators for 1 Subwoofer size and similar excursion)

A location offers the possibility to install additional weight to vary the rendering of Audible SD315-PR radiator. We can reduce the resonance frequency and increase the QMS (mechanical Qualie).
