Yes, probably around 1000W when you constantly listen to noisy sound at very high volume. The consumption is mainly to driving the bass drivers of this small non-ported closed acoustic system. When you have a Phantom you can carefully hold your hands on the drivers and softly try to move them. You will feel the resistance that the closed small volume housing has (don’t try to move them by 2cm
). It is like a inflated tyre. At high pressure it is difficult to squeeze and requires a lot of power to do so. The same with the Phantom bass drivers. To have them move with 1 to 2 cm excursion needs a lot of power. The 4500W peak they can deliver very short time due to the capacitors that store energy to be made available very fast and for short amounts, e.g. a bass drum kick. Under normal room listening conditions (SPL around 85-90 dB) only a fraction of this power is needed. The drivers barely move and the power consumption will be less than 100W for a pair of Phantoms.
