[QUOTE="Douglas R. Allen, post: 75040, member: 71"] Re: SRX718 to 'what powered/active sub?' Jeff; I was looking at the spec sheet. [url]http://www.fbtusa.net/files/MITUS_118SA_USA_combined_PDF2.pdf[/url] The amp is listed as 800 watts rms yet they have a 2400 watt peak listing? Of course I realize the time is listed in ms and SPL is listed in ms as well but all spec's seem stretched somewhat. How do they sound in real life? Frequency response. The 6 db down point is listed at 36hz. Looking at the frequency chart on page 2 if you call a reference line as average output of the sub to be at 100db output you find its 6db down point to be more "around" 46hz. ( I'd call the sub + or - 3 dbs from 50 to 105 hz ) At 36hz the chart shows its output to be down 20dbs from the 100db output reference. There is no 1/2 space or full space listed for the chart but the spl is listed on page 1 as half space. If the 36hz 6db down point is measuered after half space loading that would mean a 14db increase from full space to 1/2 space loading? For 2 grand I'm wondering "How Did They Do That?"
