This party was mostly dubstep, like the really loud and screechy stuff
I would argue this music is a pretty extreme use case. It's in tuba territory for sure some of this stuff is even lower than 30hz. Not only that but the djs run levels hot, the music itself is generally self released and poorly made and or uploaded, whether that's intentional or not. But the rig was holding its own for sure. We are in a pretty competitive market so we are competing with Danley, PK sound, HSD, Yorkville, Turbosound, and Kv2, plus a slew of other diy rigs. I can confidently say this is one of the more optimal systems in the area for fringe bass music. The wall loading really flattens things out nicely, the whole room felt like it was on fire
with the theme it felt appropriate to bust out my RTA mic array and REW and really hammer that room out and after moving the subs around WOW. Tons of fun to operate and absolutely brutal spl levels.
I was worried using anything but the 3012ho would leave performance on the table but... I'm really not sure I even want or need that extra headroom. As far as I'm aware the s2012 has the next highest VD compared to the 3012ho out of the drivers recommended. If I build more I would certainly continue using these woofers. And if you are reading this and questioning whether you should use the kappalite or basslite, ask yourself how far away the audience is going to be
