Yes. With low gain (11.86 dB per
Hypex spec sheet) and 4 V input, the maximum power you'll get is 30.7 W @ 8 ohms (output voltage = 15.7 Vrms).
But be aware that the power handling spec of a loudspeaker may not be what you expect. By the standard test method, speaker power handling ratings are measured with pink noise, and so the power handling number they gave is for a pink noise. That means the speakers can handle 45 W of pink noise, but NOT a 45 W single frequency tone of arbitrary frequency (i.e. a speaker rated of 45 W does not mean it can handle a 10 kHz tone of 45 W, and therefore may not survive, for example, a slow 45 W frequency sweep).
Assuming your Khozmo preamp is using their 48 step ladder type attenuator, the top 11 steps are 2 dB per step and the remaining 37 steps are 1 dB per step. This means 0.631X power per step for the first 11 steps and 0.794X power per step for the rest. Below is the power attenuation curve (step 1 is full power = 1X) . You'll have to find out yourselves how many steps is 12 o'clock from full power

Ladder type stepped attenuator This is where 2 resistor and 2 switch contacts are used per step, making up a unique combination of resistors per step that add up to the impedance of the stepped attenuator you use. Effectively a voltage divider network. The total series resistance of each two...
