The high linear stroke features a flat BL curve for exceptional dynamics and impact.\u003c\/p\u003e\n\u003cp\u003eThe H6 has integral shorting rings within its magnetic structure. This feature results in exceptionally low inductance at all operational frequencies and across stroke.  This reduces motional intermodulation distortion for a much more open and natural midrange.\u003c\/p\u003e\n\u003cp\u003eThe H6 uses a woven strand-oriented polymer thermo-set cone for superior damping.  The thermal fusing ensures an air-tight surface without degrading the woven feature and strand orientation.  The result is a cone with over 600 MPa of tensile strength, vastly superior internal damping as compared to carbon and glass fibers, and a density of just 0.9 g\/cm\u003csup\u003e3\u003c\/sup\u003e , approximately 40% that of carbon fiber.\u003c\/p\u003e\n\u003cp\u003eThe H6 uses a shallow split gap motor structure and custom tooled basket, surround, cone, and spider result in a very shallow mounting depth so the mid-woofer can fit into shallow locations, enabling creative positioning for best acoustical performance.\u003c\/p\u003e\n\u003ch2\u003eCrossover Frequency and power handling\u003c\/h2\u003e\n\u003cp\u003eThe H6 mid-woofer is a wide bandwidth, high stroke speaker.  A low pass crossover should be set no higher than 3000 Hz.  The actual value should be selected based upon the paired tweeter, midrange, or full-range speaker.\u003c\/p\u003e\n\u003cp\u003eThe bottom end is robust, and can often forego a subsonic filter.  The following table summarizes general guidelines about a subsonic filter.  As noted above, this is not a hard-and-fast set of limits, and the final installation needs to be considered when setting actual crossover values and gains.\u003c\/p\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"60\"\u003e\u003cstrong\u003ePower\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd width=\"138\"\u003e\u003cb\u003e6dB\/Oct\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd width=\"144\"\u003e\u003cstrong\u003e12dB\/Oct\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd width=\"165\"\u003e\u003cstrong\u003e18dB\/Oct\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd width=\"117\"\u003e\u003cb\u003e24dB\/Oct\u003c\/b\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"60\"\u003e50W\u003c\/td\u003e\n\u003ctd width=\"138\"\u003eNot necessary\u003c\/td\u003e\n\u003ctd width=\"144\"\u003eNot necessary\u003c\/td\u003e\n\u003ctd width=\"165\"\u003eNot necessary\u003c\/td\u003e\n\u003ctd width=\"117\"\u003eNot necessary\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"60\"\u003e100W\u003c\/td\u003e\n\u003ctd width=\"138\"\u003eNot recommended\u003c\/td\u003e\n\u003ctd width=\"144\"\u003e60 Hz\u003c\/td\u003e\n\u003ctd width=\"165\"\u003e50 Hz\u003c\/td\u003e\n\u003ctd width=\"117\"\u003e45 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"60\"\u003e200W\u003c\/td\u003e\n\u003ctd width=\"138\"\u003eNot recommended\u003c\/td\u003e\n\u003ctd width=\"144\"\u003e85 Hz\u003c\/td\u003e\n\u003ctd width=\"165\"\u003e75 Hz\u003c\/td\u003e\n\u003ctd width=\"117\"\u003e65 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"60\"\u003e300W\u003c\/td\u003e\n\u003ctd width=\"138\"\u003eNot recommended\u003c\/td\u003e\n\u003ctd width=\"144\"\u003e110 Hz\u003c\/td\u003e\n\u003ctd width=\"165\"\u003e90 Hz\u003c\/td\u003e\n\u003ctd width=\"117\"\u003e80 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003e\u003c\/h2\u003e\n\u003cp\u003eNote that with lower power applications, these frequencies may be adjusted down;
