Dali Ikon 7 driven with Proceed Amp3 Power Amp ( 3 Channnel x 150W )

Hi Friends,

Do you think Dali Ikon 7 with below specs, can be driven well with
Proceed Amp3 Power Amp ( 3 Channnel x 150W )?

Its for home theater purpose, and wonder whether 150w/ch is sufficient?

I think you'd do fine with that much power (if your tastes and distances are like mine, have similar rated speakers). Maybe this would help you determine the power level you'd like for your spl goals http://myhometheater.homestead.com/splcalculator.html.

The speaker has a higher-than-average efficiency spec. You could probably get by with half that much power.

Let alone spend that much for amplification if needed.

Thank you very much bros.
I key in using http://myhometheater.homestead.com/splcalculator.html.

At 50watt, it can already produce 102.3 dB SPL at listening position. WOW.
Meaning, if i use a 100w/ch power amp, its more than enuff.....

But... when I key in 100watt (which is double of 50watt), surprisingly, it can only produce 105db SPL (only 3dB higher by doubling the watt)? Did I miss something ?

No, that is how it works, takes a doubling of power for each additional 3dB spl.
