theta crossover question


i posted this in the speaker forum last week but i think it is better discussed in ht as this relates to dts/dd settings...

looking for some direction/input on crossover settings in my theta casanova. i typically use the phase perfect crossover and my speakers are wilson wp7's which play down to 21hz, watch center 55hz to 22khz and surrounds 45hz to 22khz. i use 1 thiel sw1 sub.

i realize some is dependant on room and preference but where would you start with crossover freq/slope settings and why?

Get threat I've been wonder the same question. I've got B&W 802d's. Range goes down to 34hz I was thing of setting to butterworth 63/18 and center HTM2D 41HZ same 63/18. My sub is a paradigm servo 15. Specs say it'll go down to 17hz. I've always set the crossover to 80/24 accross the board. I just want to try something new. Any additional thoughts?
Hey Richard,
Thanks for the response. So you’re using different crossover points based on the spec frequency of each speaker? ie L/R 40hz Center 50hz and so one. Do you use some type of EQ? I'm using the SMS for my subs. The frequency response on those subs are 17hz to 80hz with a slope of 18. Should I match the slope of my sub to the speakers and what should I set that cross point to? What's an acceptable over lap?

My next question on the Theta gear is when you turn off the crossover (set to full) does setting the crossover in the Casablanca or Casanova make any difference? I've read posts of people setting their L/R to full yet they are still setting the crossover to 40/6 or whatever. I'm a bit confused on that.

I've actually changed some of my equipment since last updating my system here on agon. What I've done is installed the digi out card into the Casablanca so I can use the Gen 8 V.2 as an external Dac/analog preamp. It works seamlessly and a nice upgrade even over the extreme dacs in the Casablanca. I have a Analog rig and did not want two systems so the digi card made it possible to separate the two plus the added quality of the dacs was a nice upgrade for HT.

Thanks for your help!
Ok well thanks a bunch for your responses. At least you know what I'm trying to find out. If I hear anything that answers these questions I'll post back.

I think if you bump up to a CB3 w/extremes you'll hear a major difference IMHO. Hopefully Theta will complete their HDMI upgrade but it might take some time. Theta's new website looks very sharp hopefully this is a good sign. At one time Theta was allowing 1st owners of the casanova to upgrade to the Casablanca seeing that they ended the life of that unit. Now that ATI owns them I don;t know if that's still available.
