dtr20 Posted January 18 Share Posted January 18 I'm currently using a Parasound P6 preamp with a subwoofer output with built in crossover. I'm trying to change my setup to use my subwoofers settings to manage bass instead of my preamp. This will make demoing preamps without sub outs easier since we are thinking about upgrading. Jubilee bass bins go down to around 45hz. I currently have my SVS crossover set for 50hz with a slope of 6db. I'm really not certain what I'm doing. I've basically been taking measurements with REW and making changes. I've been trying to keep the frequency chart as flat as possible with trying to let the sub go as deep as possible before roll off. Any advice?

wuzzzer Posted January 18 Share Posted January 18 Will that even remotely keep up with the Jubilees? Quote Link to comment Share on other sites More sharing options...

Schu Posted January 20 Share Posted January 20 I'd set my sub/svs upper 'cutoff' lower... what kind of slope are you using for that xo point? Also, The Xilica 4080 will do a three-way AND a sub. Lower is going to have a more pleasing hand off to the Jubilee bass bin imho... as the two signals briefly 'Cross Over', they (hopefully) 'Sum' and if there is to much overlap, they will create a bump in output at that frequency range. 1 Quote Link to comment Share on other sites More sharing options...

I'll play with the svs crossover some more. Everything I was reading about setting a sub crossover was to set it around 10hz higher than what the speakers can do. As far as having the xilica handle the sub, I still don't really understand what I'm doing as far as settings, so I have been having someone help me with that.

babadono Posted January 22 Share Posted January 22 So your Jubes are 2 way with a Xilica 4080? If so use the Xilica to do all the crossover and PEQ to the sub. That should make it transparent and easy to swap input preamps except for level. Quote Link to comment Share on other sites More sharing options...

babadono Posted January 23 Share Posted January 23 You have XConsole SW? And a measurement microphone and REW? Quote Link to comment Share on other sites More sharing options...

Yes, I have a umic1 microphone and all the software, I just don't understand the programming. I can take measurements and import setting configs. I've been having Chris A help me but he's been busy. I just started this subwoofer piece last week. Quote Link to comment Share on other sites More sharing options...

Schu Posted January 23 Share Posted January 23 Xconsole is very daunting at first... you're not only learning a new software package, it forces you to look at how you listen to music and what effects SMALL changes in signal control can have on the overall sound... so you have to learn about sound reproduction (in terms of speaker settings) in addition, unless someone is feeding you settings. it takes time to become proficient, but it's not an impossible task if you have some dedication and are semi-fluent in computer operations. I've found the Xconsole to be a very powerful tool... Quote Link to comment Share on other sites More sharing options...

I think that is backwards... you want each segment of your speaker setup to begin rolling off 'approximately' 10Hz sooner than the lowest frequency of the next segment... for instance a subwoofer to a bass bin... the subwoofer would begin rolling off around 40Hz at its upper cutoff, and the Bass Bin would begin it's roll off around 50Hz at it's lower cutoff. set the roll off to 6db... but you can try 12db and 18db very easily to see if the slope is more or less to your liking. The reason you are doing this is because as the two signals cross over, they 'Sum' and cause a bump in response. if you aren't careful, you can cause yourself issues with unnecessary 'peaks' in frequency response at those XO points if they overlap by to much. this of course is merely generality, your specific needs might be different.

Deang Posted January 23 Share Posted January 23 I think you need to feed him while you’re teaching him. Hard to learn anything when you’re stomach is empty. 1 Quote Link to comment Share on other sites More sharing options...
