The TRADA 30 matches other reference class subwoofers in terms of SPL, but does so with a smaller and more practical form factor, even with less distortion. This provides a lot more flexibility in application, as the TRADA 30 can just as well be set up with a pole mounted top for small venues, as part of a top-of-the-line rig for stadium-sized venues.
Unlike typical ported subwoofers, where adding multiple modules together can decrease the overall efficiency at the lowest frequencies, multiple TRADA 30s achieve an audio summation that lowers the cutoff and increase dispersion control. Stacking multiple TRADA 30s is done in mirrored pairs to achieve force cancellation.
