20 Most Recent Bose Acoustimass 10 Series IV Home Entertainment Speaker System - White Questions & Answers


Hi, what causes hums from speaker is when there is no ground shield from either the power supply or from the cable you plugged into the socket from the power supply.

So you will need to check that out and replace untrusted cables for connection..

If after doing this troubleshooting exercise, you will now need to test the speaker with another set to be sure the humming sound is not coming from there.

I guess that will Do.

Have a nice day...

The entire speaker system is passive. That is, it requires amplification for each channel.

From the manual: "Compatible with A/V receivers rated from 10 to 200 watts per front channel and 10 to 100 watts per rear channel; rated from 4 to 8 ohms".

Sounds like what happened to my Velodyne DLS5000R. The power supply on the amplifier got zapped by a power surge, and fried a transformer or capacitor.

I would bet a Bose amp, like the one in my Velo, is not user serviceable. Velo requires a flat $230 swapout fee where they send me a new one. They don't even fix the one I send 'em; just send a new one. Too bad, cuz if I could open the "cage" that all the guts are in, I could replace a $3 part myself, but they have this thing glued together where it can't be opened.

There's a pretty decent write up for this speaker system on CNet. The "Speaker System" section calls for an amplifier capable of 10 - 150 watts RMS.

Bose maintains a library on their products as well. You can download FAQs, Manuals and Product Information easily. On the accessories tab, Bose lists an Onkyo receiver for $350 that will work very well with this speaker system. Of course, any quality modern stereo receiver or amplifier with power in this range 10 - 150 watts should provide good results, but better amps will be in the 75 watts and greater range.

I hope this helps - good luck
