Fabioo7 Posted April 27, 2001 Share Posted April 27, 2001 Hi all, I just need to clear up something... There is a rattling sound coming out from my sub that is killing me. I bought the 4.1 a week ago and OH GOD THEY SOUND SOOOO GREAT!!!!!!! but now i'm scared like hell because i think that i might broke something in them. I played a lot the Matrix (the lobby shooting spree of course) to show off my 4.1 to my friends at high volume... and they were blown away by the sound (I'm like a hero for them now because I was the only one who had enough money to buy them , well now i have to eat Kraft Dinner for a year now...) when suddenly, 2 days ago, in the same scene i heard some kind of a wierd noise coming out from my sub!!! I didn't pay attention because I'm new to the sound/great speakers world... So to be sure it wasn't my imagination i tried the "THX - Ultimate Bass Test" that you can d/l from napster. After 30 sec of music play, when some kind of bass mix kick in, the sub start to rattle very bad. When I put my hand infront of the port i can feel the air coming out like crazy. I tried the bass test at this settings: Play control volume: 75% Midi and Wave: 100% Treble and Bass: 65% Subwoofer, Surround and Main Volume: about half. I have a Sound Blaster Live Value, the 4 channel one. I tried to lower the windows volumes and higher the 4.1 and I still have the same rattling sound. So i was wondering, did i broke something in the 4.1 by trying them so loud or it's just me? I heard that they had somekind of limiter to prevent that kind of things!!! Please help me, i don't sleep anymore I'm always thinking: "what did i do wrong? why meee? why meeeeeeeeee?" A new Klipsch Fan who needs guidance!

Btrigg Posted April 27, 2001 Share Posted April 27, 2001 I'm not sure its possible to blow the sub without really trying by playing quick low loud bass before the limiter can kick in. I don't think you have to worry, my sub has been rattling for about 18 months now, and never had any problems accept the annoying sound it makes. I opened it trying to find something I could tighten, but I was stumped, you just have to live with it or try to put it in a place where the bass overpowers the rattle. I also heard putting a weight ontop of it helps, but I haven't tried it yet. Quote Link to comment Share on other sites More sharing options...
Fabioo7 Posted April 28, 2001 Author Share Posted April 28, 2001 Thanks Btrigg for the reply but the thing is that my set is only a week old and i'm somehow positive that i never heard that rattling sound before... This is why it's driving me crazy!!! And i'll never open the sub because it will void the warranty. I know i can return them to the store where i bought them but when i called they told me that they gonna have to check the 4.1 by sending them to i don't know where and it could take a couple of weeks. Since i live in Canada, i know that's gonna take more than two weeks. So i want to be 100% sure that something in the sub is broke or even in the preamp before sending them for nothing. Can somebody give me somekind of tests that i could try. Like i said before, i'm really a newbie... Quote Link to comment Share on other sites More sharing options...
Btrigg Posted April 29, 2001 Share Posted April 29, 2001 Is the rattling all the time, only at high volumes or only at certain frequencies? I have certain rattles for certain pitches, but only at high volumes. Quote Link to comment Share on other sites More sharing options...
Dan F Posted April 30, 2001 Share Posted April 30, 2001 Some program material contains passages with substantial extreme low frequency output (below about 30 Hz) which, being below the useable limit of the system will result in some distortion and port "chuffing". If this is what you are hearing, then it's fairly typical, and one of the tradeoffs in making the system as strong as it is for most program material. This extreme limit of program material, on average, is not very common (except in ultimate bass test signals!), so hopefully you wouldn't run into it every day. -djf Quote Link to comment Share on other sites More sharing options...

Fabioo7 Posted April 30, 2001 Author Share Posted April 30, 2001 Thanks again Btrigg and also Dan F (I'm still trying to figure out "chuffing" ) I went to the store where I bought them and we made the same bass test with a 2.1, we didn't heard the rattle so they gave me a new set a 4.1 in exchange. I'm still surprised, they were nice to me!!! I'm still hearing the rattling in the new system but less than before so I'm gonna adjust my sound setting in consequence. My friend told me it may be the soundcard sending to much bass to the speakers, something about a 1:1 ratio not being correct. But he made the same jump that i did when he first heard the rattling and saw that all the settings was almost at half... Anyway I think that it's all I can do... This is a message for the people who are thinking of buying and looked at this post, GO BUY THEM, even with the little problem that I had, I don't even regret at all the 500$ CAN that i had to pay... they are worth it. Thanks again for the help P.S: I'm soon gonna write a new topic that will be : "How to make your Promedia 4.1 happy " A new Klipsch Fan who have been guided!
