Hacking the Sonos IKEA Symfonisk into a High Quality Speaker Amp
This is cool! I wonder if you connected just one of the audio outputs to a speaker with a crossover, the system would adjust to put the whole frequency range through it?It may also be that there's somewhere on the pcb you can tap into line level full frequency audio (or maybe not - they could easily do the filtering only in the digital domain)One thing to keep in mind when doing this is the impedance of the speakers.I'd measure the resistance across the IKEA ones and whatever speakers you're using first. It may be that the IKEA ones are not the common 8 ohms. If they're more (eg 16 ohms) there's a risk that an 8 ohm speaker will result in too much current through the amplifier.
