Greetings,
Last week I had run a frequency sweep (my first ever), and I noticed two frequencies in the sweep where my VP150 buzzed considerably.
Is there an easy way to isolate or identify the driver or drivers in question and is there a process for obtaining a replacing the driver?
Regards, Spence

Axiom will ask you why you are running sweeps as they did to me once long ago when I was mapping the frequency plots of my room. The buzzing may not mean a driver is bad, it can be a vibration of something internal in the speaker or room in which you think it is the driver. Also, air can escape around the CNC cutout opening for the driver at certain frequencies causing a buzz, you can try snugging up the driver. Certain frequencies will create a buzz based on the dimensions of the room and location near walls. Anyway, unless it sounds bad when listening to music or watching movies I would not worry to much. I don't think they will replace a driver on warranty based on a sound using frequency sweeps, the drivers are tested at the factory. If you can prove there is something wrong with the driver that is a different story.

Axiom will ask you why you are running sweeps as they did to me once long ago when I was mapping the frequency plots of my room. I'm trying to capture a before/after image of my current AVR (Onkyo TX-NR905), and the new one (Marantz SR7009 ...when it ever arrives). The buzzing may not mean a driver is bad, it can be a vibration of something internal in the speaker or room in which you think it is the driver. Also, air can escape around the CNC cutout opening for the driver at certain frequencies causing a buzz, you can try snugging up the driver. Certain frequencies will create a buzz based on the dimensions of the room and location near walls. I was secretly hoping to hear this. ...of course now that I know that there are two freq. that generate a buzz, it's going to bug me. ;-) Anyway, unless it sounds bad when listening to music or watching movies I would not worry to much. I don't think they will replace a driver on warranty based on a sound using frequency sweeps, the drivers are tested at the factory. If you can prove there is something wrong with the driver that is a different story. Thanks! It sounds pretty darn good. I'm going to try and surpress my thinking about the buzzes!

Why not test each speaker individually and then swap them and do the same test again. If the buzz only happens on one speaker in the left and right orientation, then it's likely a problem with the speaker.
If the problem happens on both speakers, then statistically, its very unlikely its a driver issue.
if it happen on one location (ie left but not right) then it's likely an interaction with the room.
Gives you something to narrow the problem down.

Good suggestion except he already said it is his VP150. Must be center channel so no left and right.

i didn't notice the speaker...
so, to test if it's the room or the speaker, then try moving the speaker to another location inside the room and see if the frequency at what the buzzing comes changes.. that again will identify if it's a reaction to a speaker issue or a room issue.
