Quad Cortex with a powered Kemper Kabinet?

I’m a Kemper user with a powered Kabinet and I’m wondering if there are any other Kemper users out there using a powered Kemper Kabinet with their QC.

I thought I’d put them together today, but the volume was significantly lower overall from QC than the Kemper. The kab was at 100% and the QC was at 100% and not even close to the oomph I get with the Kemper/Kab combo.

I’m thinking the Kemper Kabinet may not be a suitable FR/FR for the QC and perhaps I should just stick with my Headrush for the QC.
