You can use the Alpha 10, just like the eight π loudspeaker uses. But if you are building a seven π loudspeaker, use the crossover for the seven π, so that low frequencies aren't augmented and sent to the Alpha 10. You also don't need to vent the midhorn rear chamber. Just make it like is shown in the seven π plans.
