The Roarr 2815 is a downward firing powered subwoofer.
It has 2 x 8" high excursion subwoofer transducers and a hefty 150 watt
rms class A/ B amplifier. This, in conjunction with a cleverly designed bass
dispersal plinth results is very high SPL (acoustical efficiency)
which is ideal for home theatre as well as high bass content (techno,
rock) music. But the 2815 is not only brawn. The two relatively
compact transducers result in excellent transients and tonality. Most
users have compared the 2815 favourably with other products at even
twice the price! it was also a team member of the award winning AV
