Mini stereo amp

Looking at a Drok stereo Bluetooth amp to drive a pair of Q Acoustic 2010’s... however appears that you can get either a 30w or 50w version.

Would these size speakers work with either? I’ve seen suggestions that the speakers should work with anything between 15w and 75w...?

Go for 50w model. Always better to have more power than not enough. 15w isn't a lot.

Yes, they will work, but you won't get the specified 30 or 50 Watt. Those are 6 Ohm speakers and the specified wattage is probably rated for 4 Ohm, which is normally the case for cheap amplifiers. You should get decent volume before hitting the 10% THD though.

Some manufacturers specify just the maximum power handling rating, because that is critical compared to the minimum. 75W max in the case of the 2010i. Some also specify a minimum (in the case of Q Acoustics), but it's more of a guide line. They will work if an amp is supplying less than 15W, but it's likely 15W+ better for more optimal performance.

One thing that is confusing is why they both come with a 12V 5A PSU. 12 x 5 = 60. Even with 4 Ohm speakers you're not going to get 50Wx2 without a 24V PSU; and both models can take a 24V PSU.

Ok thanks both, gone for the 50w version and will see if it works acceptably.
