  • Re: BeoLab 8000 sounding shrill

    Thnx Jeff! I need help of a friend to make this kind of checks. I hope to do that over the next two weeks. Will come back to this thread to share the results.

    Thnx Jeff. I'll know about the cap pretty soon. The drivers have been checked thoroughly, including the channel and music source swapping. No issues there. If it is a frequency response/distortion issue on the amplifier, where would you suggest to start?

    Thnx for your thinking and suggestions again Jef, very much appreciated! Drivers: I have changed the existing drivers from position (lower to upper and vice versa). Result; no difference. I changed drivers from a well sounding BeoLab 8000, into the shrill sounding unit. Result; they also sounded shrill. I believe we can conclude that the problem is not in the drivers. L & R channel switch: I changed the Left channel to Right and vice versa, several times. And trying this with different kinds

    Thnx Jeff! Good suggestion to plug the speaker into a different system. I did. I checked: A different system via Powerlink. Iphone music connected to the RCA of the BeoLab A digital and wireless HiFi music receiver connected directly to the audio IN connector on the Amp PCB. All of these checks resulted in the same: shrill sound. Two questions : What do you mean by "using the switch should be enough to tell", what switch do you mean? Any other suggestions if the capacitor is fine?

    Thanks again for sharing your suggestions Jeff. I will look for the capacitor on the amp output connected to one of the woofers. And also I will look for the little trim adjustments. Concerning freq response and distortion, my response is based on the definition used by SoundGuys (https://soundguys.com/frequency-response-explained-16507/). What I notice is that both woofer speakers produce sound. In the Mark I series of the BeoLab 8000, the lowest positioned speaker is the bass speaker, and the speaker

    Thnx again Jeff! Tweeter level: this is the same. Woofers: this BeoLab 8000 set is a Mark I, Type 6801, serial no: 12543880. To my knowledge the woofers are hooked up differently; one to act as woofer, one to act for mid tones. I did exchange the upper woofer speaker (mid tone speaker) for a different one, but that did not make a difference.

  • BeoLab 8000 sounding shrill

    I have a BeoLab 8000's (Mark I), having functioned properly for quite a while. Since recently the overall sound has changed. The speaker produces s shrill sound. It sounds like it's missing the low/bass. The other speaker still sounds normal, so I can clearly hear the difference. What I have checked: I tested signal input via power link vs. RCA; no difference. I exchanged the tweeter for another one; no difference. Does anyone have a suggestion for what the cause can be, and what to do for

    Thnx for responding Jeff! The woofers both do produce sound. Volume is good but sound is shrill. By the way, I found a lot of old foam sticking to the amp’s pcb. I cleaned that all using isopropyl. Unfortunately that made no difference. Any suggestions?

  • BeoLab 8000 with shrill / sharp sound

    I have a set of BeoLab 8000 (Mark I), functioned very well for long. Since a while one of the speakers has lost the balance in its sound spectrum. It produces a shrill / sharp sound. This is not like a high pitch tone, but the 'highs' sound dominant, shrill and sharp. What I have checked: I have tested by putting audio signal via power link and via RCA; no difference. I have changed the tweeter for another (good) one; no difference. Anyone has a suggestion what the cause could be, and what
