Notes

This is a premium powered home speaker used for daily music listening, typically kept indoors and run for long sessions. Because it's an active speaker (built-in amplification and wireless electronics), the most common failures involve the power supply, amplifier board, and control knobs/switches rather than the drivers themselves.

Repair makes sense if the issue is a replaceable power supply, a noisy knob, or a single electronic module-especially if the cabinet and drivers are still in excellent condition. If the amplifier board fails and repair quotes approach the threshold, replacement can be more sensible, since labor-intensive internal repairs may not restore long-term reliability.

A tipping factor is intermittent audio or popping that persists across sources and resets; that often indicates deeper amplifier or power issues. If Bluetooth connectivity becomes unreliable but wired inputs still work, you may choose to keep it and treat it as a wired speaker rather than replacing immediately.

Also consider that good speakers can last a long time physically; the electronics layer is usually the limiting factor.
