Nfraso, curious. How do you calculate that it would take 27mm for the s2? Originally Posted by

We don't know much about the Triax drivers, but there are claimed CEA-2010 numbers. Because they are averaged (20-31.5Hz), and because he uses the goofy pascal conversion which shifts the weighting, it's hard to nail down exactly what is claimed. It seems though, with what is given, that you'd need right around the same amount of throw from each driver to hit those numbers.

So 3 x 15's each with 27mm clean throw would yield 98.5dB, identical to the Cap S2 for our purposes.

That's my best guess with what's available.
