My experience is with the KEF KUBEs for the 102, 104/2 and 107/2. I use a 107/2 KUBE between the preamp output and power amp. As I understand it, the KUBE provides external equalization more commonly found in passive circuitry internal to speakers as a way of enhancing speaker efficiency. The KUBE is thus more than a bass booster. Some argue for eliminating the KUBE; KEF claims that speakers designed to be used with a KUBE are not accurate without it. In any case, the KUBE effects more than just bass. Has the OP tried to get the non-functional KUBE repaired? That would seem an obvious first step.
OTOH, setting the front LR to small and shifting LF to a pair of subs seems a not-to-bad work-around. I'd recommend a pair of used Velodyne HGS-10s with an SMS-1 bass manager. That's what I use with my LS50s with fine result.
