I wonder why we readily accept subwoofers to be active? I also think @TLS Guy
's point about AVRs is interesting, those are out of date very quickly not necessarily because they fail, they just don't contain the latest tech.
Directly to your concern:
Our speakers are not likely to fail prematurely, we have taken great care to monitor temperature / cooling etc. But in that unlikely case, they are fully serviceable.
Both drivers and amps can be replaced by basically anyone who can hold a screwdriver. I would happily trust my 8 year old to do it.
We have a five year warranty and we promise to stock spare parts for a decade. We use the best amps we could possibly find.
The speakers are also not designed to be a one stop shop, they're speakers with digital filters and power amps. You still need preamp and a source. This means there's not really any tech inside that grows obsolete or stops working. No app or streaming functionality that are no longer updated.
You can connect your preamp or streamer to the speakers via xlr / rca / optical / coax and you're up and running. This will still work perfectly fine 20 years from now.
