Question on SLA PRO orientation

#1 Post by Shelby300 » Mon Nov 09, 2020 12:08 pm

Looking at building the SLA PRO.
I know how they're supposed to be oriented.
But, they will be hanging from the ceiling and may hang a little lower than I would like.
If mounted horizontally will they sound horrible or not quite as good.
Would that be a big no, no.

Thanks

That would be a huge no-no. It puts the output pattern on the wrong axis.

Thanks, that answers my question.

Another question:
What is the dispersion angle of the SLA Pro.

Thanks

Nominally 120 degrees horizontal 30 degrees vertical, but it varies with frequency, wider in the low frequencies, narrower in the high frequencies, as is the case with most speakers.
