Do I need a crossover For my SONO SUB?

[ramchip007]

my subs are nearing completion, and I threw one together just to see how it would sound. And I guess it's a success, because before I built this sub my girlfriend was complaining about my loud stereo. And now I can't hear her complaining at all: but I am having a small issue of my TV vibrating making my screen blurry while playing music and all kinds of stuff in my house rattling and this is with just one sub , I am building two my question is do I need a crossover or equivalent? or does the DSP act as one. List of equipment is EP 2500 and DSP 1128P which I'm still kind a confused on how to set up properly and have a interface midi cable on order so I can attach my computer to the DSP,

Is the source for the subwoofer the subwoofer out on a receiver? If so there should be a low pass crossover in the receiver for that output. Are you talking about a high pass to block low frequency content?

no low pass ,I am using the subwoofer output from my TV set. For now until I wire up my receiver. I think it's crossed over some but not enough I'm pretty new to home theater audio, but I used to play with car audio, and I know, It was a must to crossover woofers. I have a feeling this DSP thing might do the trick. If I can figure out how to use it properly. This thing is going to be ridiculous when I install the second sub!

I suspect you mean 1124P? You should visit our BFD Guide to understand its use a bit better. Most people would not use it as a crossover, but it can certainly be done (I use one for that myself).

If you intend to use the 1124P as a crossover you will require design software to help you create the filters to do the job. REW is quite useful in that regard, but it still takes a bit of playing around to create a proper crossover combined with adding standard peak reduction filters (which is the normal use for the BFD).......
