Pop and rushing noises on Soundlab A1
Mar 20th, 2017 at 7:53am
 
Wanted to know if any user has encountered short popping noises with static like rushing noises on Soundlab speakers.

Purchased a set with Toroid 1 interfaces and after adjusting the bias properly intermittent annoying pops keep coming one channel more than the other. Have sent the back plates to Soundlab for examination. I do not hear any distortion from the panels in playing a variety of music. I wonder if the panels would also need to be replaced. The original speakers were built in 1988 and the updated backplates in 2006.

I am now the second owner of these A1s.

I have 14 years of experience with several different Sound Lab full-range and hybrid speakers.  Generally speaking if you hear an issue everywhere on a panel it's a backplate issue.  If you hear it only in certain spots of a panel it's a panel issue.  My guess is you have a panel issue.  Good luck and let us know how it works out.
Cheers,
George

Thanks very much. We shall see. I wonder if it is the panel why this would be so? It seems then that the longevity of these are very short lived. If Soundlab replaces these with new panels the price seem reasonable but I hope the durability improves.

I own IRS Betas and their ribbons are still perfect. Also the high frequencies on these Soundlab are quite a bit rolled off. Maybe is the thick grill cloth that are there now that do not let those highs blossom. Plates have Toroid 1.
