With servo one thing to consider latency. Sure driver speed maybe fast..but there is latency from the feedback circuit (it takes time for the output signal to be fed back to the input and mistakes the mechanics the woofer made being corrected to what the input was) takes as much time as it sounds. something Arnie nudell, Genesis Loudspeakers. INFINITY SYSTEMS..nuclear engineer responsible for the first servo controlled speaker in 1969 infinity servo static 1A was $50k back when hotdogs were a nickel and plasmatronics flame tweeter debuted In 69..before my time has been trying to conquer since 1969 . MY point being servo has drawbacks also lacking attack and speed in the sense of phase linearity..it falls behind the rest of the group when all playing in symphony....jl has been around since 1975..they’ve made a huge impact in autosound industry especially in the late 80s and 90s they were on par with infinity IRS V woofers graphite injection molded poly cones not cast basket yet until the jlw7
Series came out in mid to late 90s jl has a fine mix between accurate low fundamentals with ability to play loud with minimal distortion with impressive mannerism...I’ve sold more paradigm , than i can begin to mention also high end dynaudio. Mark levinsons brand cello.Eggleston, Goldmund reference. mbl. Jm labs , Worked at 14 high end stores and 5 high end manufacturers engineering and assembly everything..also marketing CES and Stereophile shows blah blah... USACI, IASCA. In my opinion the jl is a naturally aspirated f22 raptor and the paradigm . RhythmIK audio velodynes etc servo units are AN 87 BUICK GNX (maybe a bit extreme..lol) OLDer unrefined technology that performs well..not quite what newer technology such as jl audio drivers amplifiers and cabinets offer. If u want loud make a digital designs 18 z series in apropriate enclosure and throw a 10000 watt crown on it orlook at the stereo integrity 24 in woofer or rockford fosgate 19 steve Meade designs 18 SMD 18 or (Adire Audio PARTHENON) phoenix gold cyclone Bruce Thigpens TRW 17 fan subwoofer of eminent technology frequently response 1hz -30hz...everyone else has theory of WHat is and what should be I’ve been around a bit also I have owned Irs V subs 12 X 12in servo woofers with 1000 watt amp also modified kappa 9s and rs 1B’s all servo all for infinity. its when i began mastering live music i realized how far off servo bass really is from reality . Running a mastering lab and engineering loudspeakers around what live music sounds like ... it doesn’t have latency in the low-end like servo subs...I do like the level of accuracy of servos it’s the lost time and disconnection to the entire performance Is just something i can’t get over..it’s all a compromise..which imperfection can u tolerate the most?...my lousy 2 cents...
