Overview
The Sub115 is a 15 inch, vented subwoofer that is designed to provide
low frequency support in installations requiring high SPLs from a
compact enclosure. Its high power transducer provides a physically
engaging musicality like that produced by larger systems.
The Sub115 requires digital signal processing, and many platforms
are supported. The Sub115 is an excellent option any time a low
profile subwoofer with robust SPL capability is needed. This makes
it the perfect choice for distributed low frequency reinforcement in
nightclubs, restaurants, and theme parks. It is also well suited for use
in a compact DJ booth and as a VLF channel in A/V screening rooms
or for multi-media playback.
Technologies
The 15 inch woofer in the Sub115 has a high power, 4 inch voice coil,
and is capable of impressively large excursion. The enclosure is
optimally tuned to provide maximum low frequency output in an
extremely compact package.

Notes
1 Performance Specifications All acoustic specifications rounded to nearest whole number.
External DSP with Fulcrum Acoustic-provided settings is required to achieve the specified performance.
2 Operating Range The frequency range within which the processed response is within 10 dB of the average.
3 Power Handling Based on the AES power handling of the transducers.
4 Nominal Sensitivity The 1-meter-referenced SPL produced by a 1 watt band limited pink noise signal,
with no processing applied.
5 Equalized Sensitivity The 1-meter-referenced SPL produced when an EIA-426-B signal is applied to an equalized
loudspeaker system, at a level which produces a total power of 1 watt, in sum, to the loudspeaker subsections.
6 Equalized Maximum SPL The 1-meter-referenced SPL produced when an EIA-426-B signal is applied to an
equalized loudspeaker system, at a level which drives at least one subsection to its rated power.
7 Resolution All response graphs are subjected to 1/6 octave cepstral smoothing with a gaussian weighting function.
8 Axial Sensitivity The SPL plotted against frequency for a 1 watt swept sine wave, referenced to 1 m with no signal processing.
9 Axial Processed Response The axial magnitude response with recommended signal processing applied.
