I'm looking for a bit of insight on why people say to set sub xovers at 80 HZ.
Below are the specs for my 2way speakers and my subwoofer.
It looks like my Subs useable prime range can go significantly higher than 80 and still be right at home (25-250 Hz), whereas my 2 ways cut off at 70 HZ (70-22000 HZ), so I'm assuming that at 80 they are at thier very limit of capability. why am i pushing them so low when my sub can easily fit the bill on paper?.
What would the harm be in setting my xover at 150HZ?
It seems unheard of from what I've seen so far but it makes sense to me on paper at least. What am I missing?
Keep in mind I'm not bumping rap or competing I'm just listening to a variety of genres but want them to sound like they do live as much as possible.
It seems like the sub can go a bit higher than 80 and be in it's prime efficeincy whereas the low end of the 6 1/2s is really probably at the end of it's capability to reproduce that low.
Any thoughts (obviously I'm going to try it when I get around to it, just wanted to see what people think)
One thought I had was that at a certain frequency it might become more obvious that the bass was coming from all behind me., I don't know what the frequency might be. But I'd guess it's higher than 80 HZ.
I'm also considering overlapping the frequencies a bit, i.e. keeping the compnonents at 80-100 but letting the sub try on it's wings at 150ish.
It's a good tight sub so it seems like it might make my low end even more impressive and blend more, although I've no complaints now as far as blending goes.
