			|  | Hi Karetnikov142, 
 There's no way to obtain results below 100Hz.
 
 Best regards,

			|  | Dear Karetnikov142, 
 Most reputable manufacturers have simulation software - some are better than others.
 If you're only interested in the Direct SPL, it may be better to look at using the manufacturer's SPL simulation software.
