Members southtexslinger Posted September 6, 2008 Members Share Posted September 6, 2008 I play through an old Peavey TNT 150 1x15 combo, when playing loud and I hit a C, a low E, or a low fretted A, there is an loud buzzing/rattling sound, thought it was something loose inside so I opened her up to check if anything was loose, everything seemed ok, looked like the speaker was cutting out, it's stamped with "10032", not sure what that indicates, but there are no wattage or ohm ratings on it, The amp pushes 500 watts, could it be that the speaker (stock sheidfield) is a lower rated speaker? Would getting a speaker that can handle the 500 watts fix the problem? Link to comment Share on other sites More sharing options...

Would getting a speaker that can handle the 500 watts fix the problem? Possibly. First, I would take the amp elsewhere to see if it still does it. Another room, or outside perhaps. Basically, try to get it away from anything that may induce buzzing/rattling. Play through it with a different bass and different cable... and no effects. Get rid of as many factors as possible. You can also try playing through it upside down, on either side, or even laying on its back. This might help determine the source. It could also be the cab itself. Check all internal bracing and joints. It could also be that the speaker is not securely mounted anymore. After a speaker in a combo comes loose, it can become very difficult to fix any assiciated rattling. Finally, the speaker may just be old... the voice coil may have become slightly warped from years of use... the cone might have attained inconsistencies/small tears due to moisture/temperature changes... etc. Link to comment Share on other sites More sharing options...
Members Mudbass Posted September 6, 2008 Members Share Posted September 6, 2008 Your TNT 150 doesn't have anywhere near 500 watts, it has 150 and I'm guessing that rattling sound you hear is probably a blown speaker. A common symptom of trying to push a too small combo to keep up with a too loud band. Link to comment Share on other sites More sharing options...
Members southtexslinger Posted September 6, 2008 Author Members Share Posted September 6, 2008 It states 500 watts in the back, but yeah that's probly a bit much, at lower volumes it sound good, but when the volume goes past 5, it buzzes really badly. I checked the cab to see if anything was loose and everything seemed to be secured tightly. Link to comment Share on other sites More sharing options...
Members chris-dax Posted September 6, 2008 Members Share Posted September 6, 2008 PaulyWally has the rx...it's just a matter of systematically eliminating the possibilities... it probably is the speaker (driver) itself...but could be the cabinet or a number of other things... a really good way of checking the driver is to hook it up to a freq. generator and just sweep it through the freq. Any repair shop can do that in a matter of minutes and shouldn't charge you much, if any, to do so...c-d Link to comment Share on other sites More sharing options...

Members Crescent Seven Posted September 6, 2008 Members Share Posted September 6, 2008 Maybe peak or something. If that thing was 500 watts, we'd all be playing them.Yo. Word, yo. It says 500w because that's the amount of power it draws from the wall, not the output power. My Peavey powered mixer says 600w on the back, but it doesn't push anywhere near that much power.C7 Link to comment Share on other sites More sharing options...
Members jannda Posted September 6, 2008 Members Share Posted September 6, 2008 It's a sheffield speaker (not the original speaker for that amp) It should have either a Scorpian or Black Widow in it. The Sheffield speaker is Peavey but is designed for sound reenforcement(PA) Although they work fine for bass I use one in my 414/115 cab (see avatar) IIRC they are rated at either 150 Watts for the standard or 300 watts for the PRO PLUS which is what I use.
