Not too long ago I upgraded my sound system by adding a Klipsch Synergy 10" Subwoofer. I plugged it in and everything seemed to be fine. Not too long after however I found my sub wouldn't kick in at the right time or it would rumble at the wrong times and sound "off". I've tried to research crossovers and frequency response and db's but every website I go to seems to have conflicting ideas on what settings I should do. Here's what I have:
Fronts: A pair of old AudioSphere Research (AG-271) fronts with 2 8" woofers, 1 5" mid range and 1 2.5" tweeter. Its response is 35-25,000hz and its crossover frequency is 2500 & 7000hz.
Centre: A basic mid size Precision Acoustic centre with 2 5" mid ranges and a small tweeter (not sure of size)
Rears: Again, basic PA rears, don't know much about them
Sub: Klipsch Synergy 10" Sub - Range from 40hz-150hz
Receiver: Yamaha RX-V800.
According to one website I went to, I should set my frequency cutoff on my receiver to 60hz, unfortunately my receiver does it in strange stages and I can get as close to 63hz. It also states my crossover point on my sub should be also set to 60hz. They base this on the size of my woofers on my front speakers which are 8"s.. yet the frequency claimed by the speakers are as low as 35hz.
My phase is set to 0 which seems fine I guess, and my volume is dead centre. Based on these settings i'm getting rumbling at the smallest hint of bass, from the sub.
I know there are 101 places to go (including this site) to read up on this before I post, but that in itself has been the main confusion for me, so I figured i'd try some experts.
Also, one last thing.. should I just connect the LFE connection on the back of my sub, or the LFE and Right connection together??
