Sony SS-H6600 speakers: how to give them a second life with a cheap amplifier
Salvaging the speakers from a dead Sony micro hi-fi system sounds simple, but when the bass and treble modules come separately, things get complicated. The 6-ohm woofer and the 8-ohm satellite cannot be connected directly to a normal stereo amplifier without a crossover or a 2.1 amplifier with an active filter. The resulting parallel impedance is around 3.4 ohms, which some Chinese class D amplifiers can handle, but without filtering frequencies the woofer will reproduce treble and sound like a barrel.
The technical dilemma: crossover or parallel?
The original system used passive bi-amping with a crossover built into the micro system's amplifier. To use these speakers with a conventional amp, there are two routes: adding a passive crossover (a 6.3 mH coil for the woofer at 200 Hz, not exactly cheap) or buying a 2.1 amplifier with a subwoofer output and active filter. The most recommended option in the discussion is the latter, with models like the Fosi BT20A or the Aiyima B01, which include Bluetooth and allow you to adjust the crossover frequency. Connecting the satellite to the main channel and the woofer to the sub output gives you a balanced sound.
Low-cost options for a garage
On a budget of €50, Chinese class D amplifiers offer the best value for money. The Aiyima B01 costs less than €40 and handles impedances down to 2 ohms, ideal for a parallel load. Another alternative is connecting the two modules in series (12 ohms) to avoid straining the amp, though you lose power. The most practical folks simply recommend buying a second-hand portable Bluetooth speaker before getting into frequencies and filters.
Conclusion: tinkering comes at a price
The discussion makes it clear there is no single solution. For those who want to make use of these speakers out of nostalgia or hobby, a 2.1 amplifier with an active filter is the cleanest path. For those who just want music in the garage, a €30 Bluetooth speaker can sound better without the headaches. The final decision depends on how much you value the pleasure of getting something working that others would write off as dead.
