I haven't yet met anyone that has played through this amp, so I can't comment on quality even via 3rd party, but on paper it certainly looks good, especially for 298€ Power: 800W @ 4Ω Class-D ICE power amplifier 4-Band EQ Smart Compressor DI output with pre/post and lift/ground switches High/Low switch for active/passive bass Mute function Tuner output Line input with volume control Headphone output FX loop Speaker Twist speaker connections - min. 4 Ωs Dimensions 240 x 255 x 88 mm Weight: 2.9 kg

800 Watts. Is this what it takes to deafen rats in the basement so the cat can catch them more easily? Wouldn't a younger cat be a preferable solution?
I have read that bass frequencies require more power, although I'm not sure I understand why. Is that because they get absorbed more? Does bass sound different in bare stone? Does Bach's organ require 800 men pumping air into something so the bass line can be played?
Questions…

It is not specifically that bass needs more power, it is due to the driver's usually being less efficient in the bass range, specially below the resonance frequency of the speaker cabinet itself, which drops off quickly meaning that more power is needed in order to reach the same SPL.
If you were to have a speaker that was linear in its response, say from 50Hz up to 1kHz, then the same power would produce the same SPL at any frequency from 50Hz all the way to 100Hz (edit: I meant 1000Hz). Most drivers/speakers are not linear in their response.
At the same time, when getting in to the really low frequencies, let's say below 40Hz, the human ear also has issues hearing these frequencies which means a higher SPL is needed in order for the human brain to perceive the same loudness.

Nature doesn't want bass players to be heard. Time for subtitles, I suppose…

Does Bach's organ require 800 men pumping air into something so the bass line can be played? Questions… Lower frequencies have longer wavelength, which requires the speaker cone to move longer distance to push the air and make wave happen. This is why you can see the subwoofer cone moving visibly, but guitar amp cone not. I also think bass frequencies don't benefit from 'nice tube distortion' as much as higher ones, so you want less breakup. From personal experience, you need about 150-200w solid state bass amp to play with a rock band. That 800w is a bit overkill, but hey, why not. Usually the bass heads are around 300w, giving some overhead.

Moving "a longer distance" creates a larger amplitude (louder), not a longer wavelength. Distortion is not related to frequency either, only to amplitude.. The explanation I usually get is that our ears perceive lower frequencies less, so they have to be louder to seem balanced with the rest.

Ok so is it actually vice versa: in general higher frequencies carry more energy at certain amplitude, so bass needs higher amplitude to be as energetic (=loud)? This would explain why we perceive bass as less loud. Also it's true that speakers lose efficiency when going towards lower frequencies.
