Connect 8 ohm speakers to 4 ohm receiver
Bose product name: ACOUSTIMAS SERIES II HOME THEATER SPEAKER SYSTEM
What devices were you using that were affected and what version are they on (e.g. Samsung Galaxy S9 on Android 11, iPhone X on iOS14, etc.)
Sony STR K740P Receiver
Detailed description of the issue and steps to reproduce
The impedance of speakers is 8 ohm and for the Sony receiver is 4 ohm
What environment do you experience the issue in? (e.g. noisy office, quiet kitchen, etc.)
Sound is higher pitch and virtually no bass!
When did you start to experience the issue? Did it work correctly previously?
The system was working perfect in more than 20 years. After my old receiver is dead, I try to connect to another one.
Any troubleshooting steps you took
I've tried to change set up as instructed on the receiver's manual but still no luck! I've got an advice to connect an 8 ohm power resistor in parallel with each speaker to make them 4 ohm but I'm not sure if it is a good solution! Please help me to solve this problem!
