PWR : RESTORED
Swap it.
Don't scrap it.
When a powered subwoofer or studio monitor dies, it's almost never the speaker — it's the amplifier board inside. We build plug-and-play replacement boards you can swap with a screwdriver, and repair the boards we don't make yet.
01 — Swap the board yourself
Drop-in replacement amplifier boards, matched to your exact model: same footprint, same connectors, no soldering. If you can use a Phillips screwdriver, your speaker is back in about 20 minutes — with a 24-month warranty on the board.
Browse boards02 — Or mail us the board
Model not standardized yet? Unscrew the amplifier plate, ship us just the board, and our bench repairs it at component level, tests it, and ships it back — return shipping on us. No fix, no fee.
How mail-in repair worksFind your model
Every supported model has its own diagnosis page: the symptoms, why the original board fails, and the fastest way to get sound back.

Why boards, not bins
Diagnosis first
Every model page walks you through the symptoms so you don't buy electronics your speaker doesn't need.
Built past the weak spot
Our boards rebuild the exact section that killed the original — with 105°C long-life capacitors and real thermal headroom.
24-month warranty
On every replacement board. Repairs are no fix, no fee.
Less landfill
A healthy cabinet and driver deserve a $100-class fix, not a dumpster.
