PS Audio Sprout

Give it a try.

The slight mid-bass boost of the Sprout will most likely require repositioning of your open baffle speakers (in order to give it a fair shake).

I’ve been intrigued by the pro reviews of the Sprout in that regardless of any stated shortcomings there is recurring mention of how fun and musical is sounds.

If I understand your speakers correctly the bass increases as they are moved out from the front wall (up to a certain point), so they may sound better a little closer.

I think the bass boost is around 60-65Hz (difficult to read the measurement graphs) and you may find that you enjoy the added jump factor.
