Subsonic Rumble Solutions

the filters mentioned here are only masks trying to cover up another more basic problem and will only cause other unintended consequences. if the problem occurs in no other sourse, it is the tt and/or it's set up. the "rumbling" or "pumping" is not, i repeat, not a part of the vinyl medium that we must live with!

acoustat6 in your post i am not sure what you were suggesting? but if it was that my system was no "able to reproduce" because it does not meet your high standards, well all i can say is thanks for the laugh. i only hope to some day meet your lofty standard.

acoustat6 you must be reading a diferent post then i am. ptmconsulting posted a question based on his analog equipment with hiss tt and it's set up. also seeing that no normal human can hear below 20hz and that sound at that level is felt and he descibes the problem coming from his "speakers" and not sub. i own no vinyl music that i believe goes below 20hz. i do not listen to organ or classical music. although i listen last nite to stealy dan's "gaucho" and that could be definatly felt. l believe the rumbling he is descibing has to do with the tt set up, either in the bearing or platter or plinth with those steal screw feet and definitly is not something inherant in vinyl and that one has to settle for or mask. one of my first tt's had a similar problem. over a certain volume the tt would resinate. OH and my system sounds STELLAR, thank you very much!

the kicking of the drum or the pluck of a base string can be felt as well as heard. my wife, who loves to say "i hear no diference" feels it as well. it is not a rumble but an extension of the sound. it is tight, well defined, inspiring and adds to the music. heard often in steely dan, van morrison and dire straits albums amongst others, it gives the feeling of being there. on a diferent point it is my understanding that sound under 20hz can not be heard by the naked human ear, but only felt. also with some changes to his tt the originator of this post claims to have solved his trouble. i do understand your point, just don't agree. i avoid placing anything between the source and speakers, other then the minimal required. i subscribe to the therory, less is more and try to seek it in my equipment(2 channel) set up. you seem to be more technical savy then i. notably i do not have agreat knowledge of 20hz-30khz, -3db or such, but i know what sounds good to me. i have a very mechanical type mind and see flaws in the physical makeup/desighn once i understand the workings such as in the tt in question. i do not wish to be argumenitive and insist i know all, i am certain i do not. it is just your solution goes against my listening belief that if something is off there is a reason and something is wrong in the chain and the repair is not by altering but to repair, adjust, get rid of or replace. i have a relitively large vinyl collection some are better recordings then other. it occurs to me that you probably have a sub, i do not know what your system consists of, i do not, and you are referring to sub rumble which i have heard caused by the sub trying to make sounds out side(above) it's capability. i do not use a sub because i do not like nor feel that they are true to the sound of the music, movies yes. they tend to over state or exagerate. but to each their own.

Ptmconsulting; i am confused, are you talking about cone movement on your sub or your speakers?

disconect sub i agree. thickness of the vinyl, no way. i have some 2000 vinyl albums of all thicknesses and age. rarely does newer thick vinyl sound better then the original ussally thinner vinyl. there is little doubt in my mind that the main problem is your tt. i do not know where you live but bring me that vinyl and i will prove it.

let's see, subsonic filter, rumble filter how about an air filter? to bright ad a tweeter filter. mids not right add a mid booster filter. how about, system sounds bad, get a better system.

hey acoustat6, i knowlonger own the 800d's. i have had duel subs before. no longer, not part of the REAL sound of music. ponder this bob, when you get a real two channel system, you can let us know!
