JBL 4344 type lens for theater 4 pi

Hi..
I ordered a set of delta15a + psd2002 to build theater 4 pi.
While waiting for them to arrive at my door, I am wondering if
I can use the JBL 4344 type horn lens(the one that is used for midhigh)instead of the recommended h290 type.
Actually I do not have any info about this type.
Do you have any idea about this Wayne?
Thanks
