QSC K12 Vs Mackie SRM450

QSC K12 and Mackie SRM450 are both two-way powered active speakers that are very popular in the market for studio monitoring as well as live performances. The two seem to come with similar specifications. However, how do they compare to each other? Are they equal in real performance, or is one actually better than the other? How about the features? Below, we are going to put QSC K12 and Mackie SRM450 against each other in order to determine which model makes the best bang for the bucks!


Comparing their sizes, we must say that Mackie SRM450 is more compact and portable than QSC K12. Mackie SRM450 is a little bit smaller and also more lightweight. These traits allow for easy installation and uninstallation. However, QSC K12’s slightly bigger and heavier body will not be much of an issue if you plan to put it permanently in a specific place. Mackie SRM450’s housing is constructed of a solid and strong plastic material, featuring a 12” woofer and a 1.4” compression driver. On the other hand, QSC K12 introduces ABS enclosures that are exceptionally rugged and lightweight, also with a 12” woofer and 1.75” diaphragm compression driver. (See also : QSC K12 Vs JBL PRX712)

Now, comparing the performance of the two speakers, QSC K12 turns out to have the better edge. It has a more balanced and wider frequency response range, which spans from 52 Hz – 18 kHz. The extensive, feature-packed DSP (Digital Signal Processing) performs a very good job in handling and reproducing the audio signals. The lows, mids, and highs are balanced and accurate. The sound is warmer compared to Mackie SRM450. It can also deliver louder volume levels while keeping full, solid, and clear sounds. On the other hand, Mackie SRM450 is quite considerably harsh and brittle. There is also an issue about Mackie SRM450 shutting down whenever the speaker gets a little bit too hot; you can’t push the speaker any way too far.

Mackie SRM450 comes with the handy one-button Feedback Destroyer. Whenever you face a feedback issue, all you have to do is pressing the button, and the feedback is gone. There is also a two-channel mixer. However, QSC K12 indeed comes with an onboard EQ and a more powerful mixer. It is able to accept and control all the three input sources (a mic input, a line input, and an iPod/MP3 player input) simultaneously, and even pass the combined signal to another powered speaker.
