I have an old computer speaker setup assembled from various hand-me-down parts. Recently, the right channel started cutting out, then stopped working completely. I also damaged the speaker connector while trying to adjust it, although I already know which replacement connector I need.
The bigger issue is the powered subwoofer. Its RCA input no longer produces any signal, and I'm considering opening it to inspect or repair the port. I wanted to find a teardown or repair guide first, but I can't find any information about the manufacturer or this specific system. The logo shows a lowercase "i" followed by an uppercase "P," with "IPSOINFO Information Technologies" written underneath. The back of the subwoofer doesn't appear to provide a useful model number.
Does anyone recognize this brand or know what kind of hardware may be inside?

IPSOINFO seems to have been a small Italian computer brand that sold or rebranded mostly inexpensive, partly self-assembled hardware. It appears to have disappeared around two decades ago, so finding an official manual or teardown may be nearly impossible. Look inside for an OEM manufacturer name, board number, or part number and search those instead of the outer brand.
The problem may be simpler than the missing brand information suggests. A loose wire or solder joint inside the speaker or subwoofer could explain the dead channel, especially after the connector was moved. The speaker driver itself only needs two connections, so a detached wire can sometimes be repaired by resoldering it, but inspecting the powered subwoofer still carries an electrical hazard.
Be very careful about opening a powered subwoofer. The amplifier section can contain capacitors that retain a dangerous charge even after the unit is unplugged. The warning on the back should be taken seriously. Unless you know how to discharge and work around mains-powered audio equipment safely, replacing the system may be less risky than repairing it.
