Tc2+ 15

How high can these puppies play in an IB set up? Im Not too concerned about how low they can go, just how high before cone breakup etc.. becomes an issue?

The 12's are fairly reasonable to 175 Hz. I've never measured the 15"; look for the frequency range where energy storage in the ETC plots sets in. That's where I prefer to cut off, though some will use part of that range, too. If I had to take a WAG, I'd say 125-150 Hz clean. BTW, I use the 12's in single voice coil mode, too- better Q for a dipole, and less VC inductance.
