|   High Pass or Low Pass For Your Sub?? | magictooth
Apr 10, 2003 1:07 PM | | Do you guys have any opinions about whether the high pass filter or the low pass filter is better when connecting your sub? If you connect both, what happens? How about if you are bi-amping, do you want to maybe use the high pass filter to the amp attached to the mid/treble driver(s)? |

If a particular woofer, say, will not correctly reproduce midrange signals, why send midrange signals to that woofer? Ditto sending bass to the midrange speaker, or 'satellite' speakers. It is appropriate to send men to the men's bathroom & send women to the women's bathroom. You wouldn't want to send women to the men's bathroom....would you??
A satellite speaker will consume the power in the low-frequency signal that the satellite amp sends to it, even if the satellite speaker is unable to produce sound with that low-frequency signal. |

Apr 10, 2003 9:01 PM | | Hmmm.... Sorry, I thought I was pretty clear. What I want to know is do you guys generally hook up your subwoofer (with separate amplifier) via the high level inputs, ie the 5-way speaker binding posts on the sub, or the low level inputs, ie the RCA jack that goes from your receiver/amp's LFE output and then splits off to a red/white RCA connection on the sub.
This is my case in particular, which is maybe why you're a bit confused: my receiver has a fixed LFE crossover set at 80 Hz. The sub amplifier has a variable crossover from 40-150Hz. My main speakers are rated 30-20KHz +/-3dB.
Right now, I have my receiver set to "large" front, "none" for the sub, and "small" for the center/surrounds. I've connected the front speaker posts via Home Depot wire to the high level inputs on the sub's plate amp, and from there to the mid/treble driver of my main speakers. I've got another wire that runs directly to the bass driver of my mains. I've removed the jumpers from the mains' binding posts.
I've set the sub's variable crossover at about 50-60Hz. It seems to blend quite nicely. My question is whether this is the best way of hooking up the sub, or should I be looking at doing it another way.
One last wrench to throw in there: I've just bought a five channel separate amplifier. I wonder if I should bi-amp the front 3 channels using the separate for the mid/treble and the receiver's amp for the bass drivers. How would you guys recommend hooking up a situation like that? |
