KEF KUBE 104/2 modification

Hi, I recently acquired a KEF KUBE 104/2 active bass equalizer. I know it was designed to use specifically with the KEF 104/2 speakers. But, I’m thinking to use it with the non-KEF speakers—ADS L1590/2. Regrettably, the brochure and the owner’s manual of the KUBE 104/2 have no technical literature anymore. Does anyone know its specifications, such as tuning frequency and Q? Also, it would be really appreciated if anyone know how to modify its tuning frequency and Q.

I think there are some posts related to the Kube here. They may take a bit of digging out though.

Circuit diagrams are scarce and maybe to accomplish this you would have to measure and then calculate the necessary filter frequencies, order and Q.
A goof OP amp filter book would be a wise purchase.
Definitely a winter project, as it may need a bit of time and effort.

Possibly the relevant hypex modules would be far more flexible. The resale value of the Kubes will be higher I think if they are untouched.

You will also need to buy a measurement electret microphone, and the preferred microphone pre-amp with phantom power for the mic. Add to that the learning curve on how to use the Hypex software. and taking good measurements. Which is probably is a more expensive and equally time-consuming winter project.

I assume you went with the Kube option as they were a bargain?
