I have a pair of the speaker (4 line cable).But the amplifier is broken.
So, I am finding a new amplifier to drive the speaker. The spec for my speaker is 4ohm and 15w.
I just see a project on Kickstarter, it is a Bluetooth amplifier with magnetic plug connection.
It seems not bad. May I ask this Bluetooth amplifier is it suitable for me?

Quite honestly, I would use an amplifier with a standard connector instead of a Kickstarter produced amp with magnetic coupled connectors. I can’t tell from the web page when it will be available and am unable to find any electrical specifications for the amp section.
