From the invention of the first electronic speaker by Johann Philipp Reis in 1861 to the creation of the first prototype loudspeaker in 1921 until today’s modern loudspeakers, it is amazing how technology evolves through time. The audio and music industry has greatly benefited from the discovery of active loudspeakers.
Although active loudspeakers are usually heavier than passive loudspeakers, because of their built-in amplifier, a setup of passive loudspeakers and a must-have amplifier will still weigh more than an active loudspeaker with its built-in amplifier. This is why many love buying active loudspeakers.
QSC is one of the leading manufacturers of active loudspeakers globally. They are offering their entry-level and mid-tier 12-inch loudspeakers in the market; the QSC CP12 and QSC K12, respectively.
Deciding which of two you should purchase is really a difficult decision to make, that is why we are going to help you make the right choice.
