Speakers for B4II

I want to run B4II through a pa amp and speakers rather than through a keyboard amp.
I have a chance to buy some cabs contaning 15" speakers with 1" drivers.
The crossover point is 1.6 Khz.
I don't know a huge amount about speakers but isn't this crossover rather low?
I'm wondering if I used them for B4II whether the 15" speakers would end up doing any work at all.
Does anyone know the frequency range of a Hammond? It strikes me that even the lowest notes could contain more high - mid frequencies than low because of the layered harmonics.
Any thoughts welcome.

 

In a Leslie, the crossover is 800hz. In that speaker, the 15" gets lots of work. The crossover in the PA speaker is not relevant. It should give you a certain range using both speakers. The crossover is for the benefit of the speakers, to keep the right frequencies in the right place.

B4II should sound great in a PA speaker with a 15". What I would concentrate on is running it in stereo since you have two speakers. The Leslie sim is certainly stereo and sounds more natural running full stereo.

 

Interesting. Thanks for response.
