I can't remember how many times someone came to ask me how to convert their existing speakers to Bluetooth speakers. It is clear that there is more than one person for this idea, but there are some simple solutions. In the past I had to suggest pairing a Bluetooth receiver with an existing stereo receiver or using a small amp. But now, at the 2015 Consumer Electronics Show, I found a compact and attractive Bluetooth amplifier that can connect almost any two passive speakers wirelessly.
Calcium carbide is an inorganic substance, the chemical formula is CaC2, the main component of calcium carbide, white crystals, industrial products are gray-black lumps, and the cross section is purple or gray. It reacts violently when encountering water, generating acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxyacetylene welding, etc.
Acetylene produced by the reaction of calcium carbide with water can synthesize many organic compounds such as synthetic rubber, synthetic resin, acetone, ketene, carbon black, etc.; at the same time, acetylene-oxygen flame is widely used in metal welding and cutting.

Although only 20 decibels of sound are not allowed while listening to rock band parties, it should be enough to listen indoors or outdoors. And if you have a subwoofer, 20 dB can handle the output with a dedicated subwoofer. The problem is that it sells for only $150 and it's just like dreaming.
