No you misunderstood my post. You will achieve 500 watts through one 8ohm cab.
With the Demeter Minnie you will achieve 800 watts with two 8ohm cabs or one 4ohm cab.
With the M700 Power amp (Hypex) you will receive 700 watts through two 8ohm cabs or one 4ohm cab. Although I will say IMO the M700 sounds bigger and louder than the Demeter Minnie. I believe the Hypex module is actually rated for 1200watts, but Jule designed the amp for 700watts using this module to achieve more headroom.
Ah, ok. Thanks for the clarification. Great information.
