I have a 1070 with PSB Image B25's for fronts, C40 for the center, and an Outlaw LFM-2 as a sub. I am looking for suggestions on setting the right crossover frequency for the fronts and center.

PSB's website gives the following info on the frequency response:

Image B25
Frequency Range
On Axis @ 0° ±1.5dB 59-20,000 Hz
On Axis @ 0° ±3dB 45-23,000 Hz
Off Axis @ 30° ±1.5dB 59-10,000 Hz
Lf Cutoff -10dB 40 Hz

Image C40
Frequency Range
On Axis @ 0° ±1.5dB 65-20,000 Hz
On Axis @ 0° ±3dB 50-23,000 Hz
Off Axis @ 30° ±1.5dB 65-10,000 Hz
Lf Cutoff -10dB 45 Hz

Based on these numbers, what would be the appropriate settings? 60hz or 80hz? I have played around with both settings a bit, but am having a hard time making up my mind which one I like better. For now, I have both the fronts and center set at 60hz.

Any ideas?
