I am still side looking at speakers that would be a worthwhile upgrade for my Mani-2 Signature and I have found two interesting Dynaudio:
Newest Contour 30, 2.5 ways Older Focus 380, 3 ways I know the limited basics about impedance and dB but I would be curious how the two models I am looking at would behave with my amplifier. More specifically, would these two models be easier to drive than my Mani-2 Signature according to the specifications. Mani-2 Signature Two-way, reflex-loaded, magnetically shielded, stand-mounted loudspeaker. Drive-units: 1" (25mm) metal-dome tweeter, two 7" plastic-cone woofers. Crossover frequency: 4kHz. Frequency response: 29Hz-20kHz ±3dB. Sensitivity: 85dB/W/m (2.83V). Nominal impedance: 4 ohms. Maximum sound pressure level: 110dB before dynamic compression. Amplifier requirements: 40-200W (4 ohms). Contour 30 Sensitivity: 87dB (2,83V / 1m) IEC Power Handling: 300W Impedance: 4 Ohms Frequency Response (±3dB): 32Hz – 23kHz Box Principle: Bass Reflex Rear Ported Crossover: 2½ way Crossover Frequency: (300) / 2200Hz Crossover Topology: 2nd order Focus 380 Sensitivity: 88 dB IEC Power Handling: > 300 W Impedance: 4 Ω Frequency Response: 35 Hz – 23 kHz (± 3 dB) Box Principle: Bass Reflex Rear Ported Crossover: 3 way Crossover Frequencies: 460, 2600 Hz All of these 3 models have a 4 ohms nominal impedance. But the dB rating being higher on the Dynaudio suggest they would be easier on the amplifier. An increase of 3 dB is said to double the sound output, then would an impedeance of 85 dB (M2S) to a 88 dB (F380) be twice as easy to drive? Or, if I plug a pair of F380, would it require half of the power that was needed with my Mani-2 Sig for the same sound output level? I am not sure it works that way so I am asking the pros.

You could also try the Contour S3.4 or S5.4
They may be better than the 30 or the 380. The S5.4 is a 3 way if you prefer that over the 2-1/2 ways.

I've been reading several posts from owners of the c20-30-60 that upgraded from older dynes and are disappointed with them. Try to get a pair that's already broke in before judging the contours.
