9. ross over with a minimum slope of 12 dB per oc tave and a crossover frequency in the range of 100 to 250 Hz Due to the high efficiency of the Sb180 less amplifier input is needed to achieve a given sound output level The high power handling capacity of the Sb180 permits the use of amplifiers with a rating of up to 1 200 watts rms into 8 ohms Speaker Protection When in the vented box mode the SubScoop like all other vented systems experiences rapidly increasing cone excur sion below the box tuning frequency The acoustic output is also decreasing rapidly therefore it is sensible to protect the Sb180 and maximize the power output of the sub woofer by inserting an active 32 Hz high pass filter with a slope of at least 12 dB per octave into the circuit Such subpassband fil ters are found in many commercially avail able crossovers and equalizers including items manufactured by Electro Voice 55180 Subwoofer Sb180 Subwoofer Frequency Response The Sb180 s axial frequency response was measured in Electro Voice s large anechoic chamber at a distance of 3 meters 10 feet with a swept sine wave input Figure 1 has been averaged and corrected for 1 watt at 1 meter Enclosure Construction Intended to be used asa portable speake sys tem the Sb180 is ruggedly constructed of inch void free plywood All joints are dado cut and the cabinet is finished with a rugged paint finish that is both attract
