Problem with my ATP3

[gurujee]

My ATP3 was running OK till yesterday. But today when I powered on the speakers, and played a movie, the woofer is full of distortion though the satellites sound perfect. Then I brought the bass level to zero, but still any sound from woofer is sounding like a wet tabla. I felt the bass is gone, only vibration is there. I am very very upset.

I purchased Altec Lansing ATP3 2 months back. At the time of purchase, the production of ATP3 was stopped. So I searched every shop and managed to get one. Like all, I had never imagined such sound quality. I was extremely happy. I am a bass freak, so I started to play at the full bass. Then after some days, I kept the bass at 50% and continued to listen at this setting. I may have done a wrong thing at first when I played some of the sound testing files like 'ultimate woofer test', 'deepest bass test' etc. After these, I felt the bass is distorting at high volumes which was not when I first purchased the speakers. But I managed that problem as I don't listen at high volumes.

But the current problem was unbearable for me. I have tested everything but no result. The woofer was unable to produce even slightest bass. Only if I lower the volume level to 10-20% the distortion cant be heard.

please advice what to do

Sorry to hear about your problem. The ATP-3 is really nice for the price. There are a few possibilities -

1. The woofer may have been damaged from the excessive bass drives you subjected it to. The cone suspension may be torn; or the coil suspension may be displaced. In such cases, replacement or repair of the woofer is the solution. Problem is, a matching woofer is probably difficult or impossible to get; and repair can be done only by someone who's experienced in doing the precision work necessary.

2. The screws attaching the woofer inside the cabinet may have been loosened by vibration.

3. The screws attaching the cover of the cabinet may have been loosened by vibration.

4. The connector jack may be a little loose in the socket.

I have seen all of these possibilities happen with computer speakers.

Just go to AL service center and get it replaced. What ever the stress level is, they are not supposed to die. If they do, they will be replaced.
