So what do you set your crossover to?

[moves]

I have a pioneer sc27 and it allows me to adjust my crossover for the LFE. I just lowered mine 50Hz letting my mains carry more of the frequency. I havn't watched a movie to see the difference yet but what do you set it at? What are your experiences or thoughts about lowering your crossover for LFE home theater?

The LPF for the LFE channel is actually supposed to be set up around 120 Hz (that's what my receiver defaults to). But I don't think you're talking about that...

In terms of the crossover for the redirected bass in the other channels, I actually raised mine from 40 Hz for all 5 channels, which is what Audyssey measured and set it at, to 100 Hz for the front 3 and 80 Hz for the surrounds. I don't know why letting the mains carry more of the signal is preferred - I can either have 140w running through a single 5.25" woofer on each side or 2400w running through two 15" woofers for those lower octaves. Which one of those seems more likely to excel below 100-120 Hz?

If I had a 2nd sub in the same general position as the current sub (up front, flanking my mains), I'd raise the crossover even higher, like to 150 Hz.

Provided you can get proper integration, I'd rather have a high crossover vs a lower one. Let each speaker play to their relative strengths.

I will add that I have not measured my frequency response in room, so I don't know how well they are crossed over, but I'm happy with what I'm hearing and I feel my approach is logical, so I'm not inclined to change it at this time.

I set mine to 80 Hz because all other crossover settings are wrong.

I crossover @ 80Hz because I can not hear a difference between that and 60 or 100 in my room and, since that's what THX recommends, I just use their recommendation. My surrounds really shouldn't be set any lower than that based of their published specs anyway.


I really need to measure the frequency responses and set it based on that...

My speakers are rated down to 25Hz +-2db so for music I go direct most of the time and for movies I usually cross at about 60 because I want my subwoofer to carry all of the dropkick you in the chest frequencies.

The crossover really depends on your room, your speakers and your subwoofer. It's all about finding that sweet spot where your subwoofer and speakers mate seamlessly. For some people, they won't be able to hear a difference in their room with a crossover between 40-100Hz. For some people, a difference of 10Hz (from 40 to 50) will make an audible difference. Play around with it and see what the differences are.

Highly dependent upon the speakers in question, the capability of your subwoofer to reproduce content above say 80hz or so, how loud you typically like to listen, how hard your speakers are to drive and how much power you have available to drive them with, the size of your room and distance to the LP, etc.

Generally 80hz is a safe bet unless your speakers are rated to say 25-30hz in which case maybe 60hz would be safe. One "rule of thumb" that I've seen people use is to set it 1 full octave above what your manufacturer says your speakers are rated to.

But a lot of that goes out the window if you tend to listen at or close to reference. Very few main speakers are going to do remain composed at reference levels at 50hz and under.

i used have cross over like 60 for mains 80 for rest.

but since if got a svs sound pb12nsd i'm running anything at 80hz
even tough mains can do 42hz
