The only reason I&#8217;m showing this here is to prove that the earlier conclusion based on a theoretical simulation holds true in real life.<\/p>\n\n\n\n<p>One important conclusion to make at this point is to realise that a loudspeaker that is implemented with a 4th-order Linkwitz Riley crossover and the same loudspeaker implemented with a linear phase crossover will have identical magnitude responses (in any direction &#8211; not just on-axis) and identical power responses. However, they will have different phase responses (in any chosen direction) and different temporal responses (aka impulse responses).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This will be another short one.
