[QUOTE="Ivan Beaver, post: 75693, member: 30"] Re: Danley SM80 and others shootout Monday January 14 at Danley in Gainesville, GA. People do sub demos all the time-and you hear-this sub is "punchier" than that one and so forth. Yet NONE of the such demos that I have attended have made any attempt to actually sonically balance the subs-level and/or freq response wise. It has just been "let them go". Now this can be real good to compare sensitivities (like we did at the demo). And if they all use the same low pass filter-then the one with the most HF extension (meaning 100-200hzish) is going to sound "punchier". Yet when you PROPERLY align it in a system-that apparent punchy-ness will no longer be there-as based on our limited testing. So is having this extra HF extension a bad thing? No.-think of it as "free sound", that you can either throw out of the sub-or not have the full range box have to extend down as low. So either one wins in the power heating game. Years ago Tom Danley did an experiment and his company compared the servo drive subs with other normal subs-and the test was to play various recording of just a low drum-kick-floor tom-concert bass drum etc and see which cabinet sounded most like the way drum should sound. No full range cabinets were used. In every case the servo drive cabinets lost. But not for any reason most would think. The question to the listeners was "which one sounds most like a bass drum?". Well the cabinets with the most distortion and HF extension had more of the overtones that exist in the real sound/recording. HOWEVER-in the real world-we use other loudspeakers to reproduce the higher freq. So the cabinet with the lowest distortion will sound more like a real drum when used with a full range cabinet. The distortions will actually interfer with the freq from the full range cabinet-making it sound less natural. The cabinets that have extra HF bass extension would have to be properly aligned with the full range cabinet. So when you start to take all of this into account-you will quickly realize it can get to be a bit harder to honestly talk about punch-and how it REALLY relates to a properly designed/aligned/operated system. Of course if the system is out of whack (as most sound systems are) then the individual cabinets can start to take control again. And we go back to "it depends"------------------------------------------ [/QUOTE]
