[QUOTE="harrybrilljr, post: 92261, member: 103"] Re: Cardioid Subs in a Smaller venue. The easiest way to make a CSA is to stack 2:1 with 1 being rear facing and usually on the bottom but that can be experimented with. Place your measurement mic where you want the deepest cancellation to occur. Measure normally(with Smaart) with the front drivers on. Capture the trace. Mute the front. Turn on the rear. Do not adjust the reference delay in Smaart. Adjust the delay of the rear driver until the phase traces match. The levels are almost always super close, but you can adjust drive if you want them matched perfectly. Turn the front back on, and you should get close to 6dB more than before. Invert the polarity of the rear. The OP could do this with 1:1 by turning down the rear facing box to match the level of the front at the rear. This set up damages the front the least since the rear drivers add very little to the front. [/QUOTE]
