This presents problems when interfacing speakers and also with crossover design and
type. Some crossovers are phase inverting through the crossover frequency, some are not.

Since there are no hard and fast answers to the problem of phase for combining drivers,
we recommend listening to the LFT-10's and midbass drivers wired all in phase and then
inverted relative to each other to see which wiring method sounds best. This applies to
any system and driver combination.
