Bose F1 812 vs QSC K12
This is just a quick comparison of the two speakers. I want to start out by saying that they are both loud. They both sound good. The QSC was able to get louder than the 812 before clipping, but not by much. Also, there was a different quality to the “loudness” from both speakers.
For the sake of my testing, I ran the 812 in the C position. I did this because I am not fully sold on the Vertical coverage benefits of the flex array. I am a DJ who will most likely always play on the same level as my audience. So that means that the “Straight” position would be my go-to position. In this position, I do not enjoy the sound. They don’t sound bad, however I am accustomed to a horn. So they just sound different. I may get accustomed to this or maybe not. Some people describe the sound as muffled. I just describe it as lacking something because of my familiarity with a horn in my top cabs. Maybe Bose tailored that sound for the straight because they knew this position would be shooting directly at heads..I don’t know. Anyway, I tested in C position because that position gave me the sound that would rival a horn.
K12 Normal/Flat vs 812 Full range – Winner is 812. The 812 had more low end and crispy sound. The K12 got louder before clipping but did not hold the same pleasant sound as lower volumes. The 812 having better bass response.
K12 Normal/Vocal Boost vs 812 Full Range – Winner 812. I chose 812 because with the vocal boost engaged, it seemed to put the vocals and high end in front of the overall music being played back. The 812 remained even throughout with better low end response.
K12 Deep vs 812 Full Range – Winner 812. This is the only configuration where the K12 could keep up with the bass response of the 812
K12 Ext Sub vs 812 With Sub – Winner 812. Sound-wise I gave this to the 812, but function-wise, the K12 wins. The EXT sub mode on the K12 seems to cut more of the low frequencies than the 812 Sub mode. This allows the K12 to get slightly louder than the 812. I do think that the 812 With Sub Mode coupled with the HP on the F1 Sub gives the 812 an additional cut that would be equivalent to the K12 Ext Sub mode.
Conclusion, I sold the K12s and kept the 812s. They are both top notch products. I was going to run the QSC with my new F1 Subs, but the entire F1 System sound better together than apart. It’s like yeah, you can run the subs under other speakers, but the overall sound won’t be the same as if you paired it with its natural mate. To touch on the flex array benefits again, I think you get better EQ benefits from the different array patterns than coverage benefits. I mean think about it, can two 2.25in drivers pointed slightly up really made a dent in the absence of full sound vertically?
