I want to use this horn https://en.toutlehautparleur.com/media/catalog/product/datasheet/sb_audience/HORN_H250.pdf , in the graph of the pdf the horn is measured with the same compression driver i will use, the problem is the recommended minimun crossover is 1800Hz for this compresion driver and im looking to cut it at 1KHz or less, im going active with a DSP. Is this possible?
Minimum recommended xover points are alot like legal disclaimers to avoid liability for product failure, imo.
Per your link, that CD's response at low level looks pretty good on that horn.
It's always a 'try it and see' but my bet is it will work fine at 1kHz and maybe a bit lower.
I would use a xover steep however, at least 24 dB/oct, until you're confident there's no excursion problems at high volume.
If you have the capability to use linear phase xovers, you could go much steeper without the usual audible damage from using steep xovers,
and the odds of having no excursion problems with lower xover points go way up.
