You're problem might not be your speakers but your amplifier. I remember in the 70's students testing all kinds of receivers they had purchased on A-7 and none sounded the same . The worse was Technics.

For low Price budget Harman Kardon Receiver 100 Watts per channel.
In the higher end Bryston and Mcintosh.


By the way Toyota run away car has to do with cheap electronics .

When buying an amp be careful where it is built.
