I have horn speakers and am in the process of considering a bass trap in the corner right net to the speakers. I have had good luck with Vicoustic Acoustic.
Is Room treatment different for Horn Speakers?
I've just recently purchased a set of Klipsch Cornwall lV's, however my room treatment was originally set up (by me) for KEF LS-50's. Are there any rules of thumb for Horn Speaker/forward ported loudspeakers?
