hi HiVi fans,

i own a pair of D1010MKII speakers, and for the past year or so they started making this hum/buzzing noise. it was faint enough that i could live with it (playing any music easily drowns it out), but over the past week the noise has gradually gotten louder and louder. today, i tried powering the speakers off and turning them back on again, and it has gotten even louder now. like... really LOUD!

the other symptoms i can describe here is that the volume control has no effect on the level of hum/buzzing, and also the noise is present even without any audio inputs.

i have zero electronic experience, and was unfortunately not able to find any resource online about this problem or how to repair it. i was wondering if somebody on this forum has some idea what could be failing here, and perhaps lead me in the right direction on how to get it fixed.

would really appreciate the help so much. thanks in advance!!

hi thanks for responding. yeah, the buzzing sound is there even with all audio inputs disconnected. also, turnting the volume up or down has no effect on the buzzing sound.

if it is an internal board or amp issue, is it an easy repair job in your opinion? just wondering if it is worth repairing, or should i just retire this speaker and find a new one? 🙏

thanks for the feedback. i ended up taking it to this A to Z electronics repair shop. the guy seems to have some experience with speakers and TVs. RM30 to diagnose so no harm i guess. wish me luck! 

will update my results.

hey man, really sorry for such a late reply. totally forgot to update this thread. unfortunately, my D1010MKII speakers are probably in a junkyard or laying in a scrap heap somewhere. i threw them away!

the electronics shop i sent them to for repair turned out to be run by a complete idiot. he did not get rid of the buzzing, and totally messed up the sound quality of the speakers in the process. so he actually made them worse! 

i figured it was time to give them up anyway. they had a good run, and i tried what i could to bring them back to life.

thanks for following up tho, i appreciate this forum! 

Hi everyone

Basically a newbie to the Hivi brand but am doing some research online to replace my recently dead Edifier R1700bt

Am wondering has anyone compared the D100 to the R1700bt and would be able to give some feedback accordingly?

Would appreciate if anyone could give some comparison (as unbiased as possible)

Thanks

I do agree with you as the specs do appeal to me altho am curious to the following

1. The D100 is a non-ported cabinet design so I presume the bass dept would be reduced but I'd assume better control and detail, can someone confirm that (as it is the Edifiers I used to use are abit boomy as is even on stands (unballasted) so I can do with less impact but better detail)

2. The one appealing feature is that it has an optical in (previously used an ODAC to channel in audio from my PC to the R1700BT @ 24bit/96khz) but I'd like to know using the realtek onboard optical out what's the maximum bitrate playable thru Hivi's DSP as I frequently listen to SACD rips.

3. Are HiVi's sensitive to placement including distance from wall and toe?

Thanks
