This speaker is heavy in weight but huge in sound. The Electro-Voice EVM12L Classic loudspeaker has been frequently referred to as "the world's greatest guitar speaker." Whether or not such a monumental question can ever be settled, there's no question that the EVM12L loudspeaker has been much beloved and extremely popular, ever since it was released in 1983. It's a 12-inch transducer with a 2-inch cone and a hefty 16 pound magnet. It runs with an 8 ohm nominal impedance, and is ready to move serious air with 200 watts of power handling. 

It is a speaker that can give you smooth, fat, rich, complex overdrive tone as well as airy, sparkly, jangly cleans with a real emphasis on clarity. It can handle just about anything you can throw at it with a high-performance heavy-duty design. 

This speaker  this goes deeper, higher, wider, louder. A large sound if your just running a 1x12 cab. A favourite of guitarists in all styles.
