Paradigm Servo 15 Level Question

Guys,

I'm working on finely tuning my home theater. My setup consists of the Klipsch EPIC CF-4's as my mains, Klipsch KV-4 as my center, Klipsch EPIC CF-3's as my surrounds and the Klipsch KLF-C7 as my rear center (6.1). I'm running 2 Paradigm Reference Servo 15 subs both through a single X-30 cross-over. My receiver is the Denon 5805. I pretty much have the location of the subs nailed down but what I'm unsure is the proper level to set the sub amps as well as the cross-over. Currently I have both subs set at the mid position on their amps and the cross-over set at -6db off the mid position. The cross-over cutoff is set at 80hz and I have the one sub phased at about 10 degrees. Other variables that may affect feedback...my room is 14' W x 22.5'L x 8.2' H with carpeted floors and skim coated drywall. The whole reason I'm asking is because my LFE seems to be lacking a little however I don't want the LFE to over power the CF-4's. I'm trying to acheive a nice seemless blend been the Servo 15's and the CF-4's at about 60-70Hz. For all of those Servo 15 owners out there where do you have your levels set at on your sub, cross-over, and receiver?

Thanks,

Ryan

I have the level maxed on the sub,12 oclock on the X30 and -8dB in the pre/pro menu.This does not tell much,as each room and sub(s) position has its own impact on the overall percieved output.

Set the subs to near max(80-90%),the receiver or pre/pro to 0 and then set the gain on the X30.When you feel there is a godo balance leave it there. Easy no?

Your receiver has the most sophisticated room equalization software known to man. Use it. It will set the sub woofer levels for you automatically. It will also set your receiver's crossover. Therefore, I would suggest you eliminate the x-30 crossover.

Here is a review of your receiver:

Here is a review of the Audessy System:

I would start out with the sub level at 1/4 volume and run the software. If it sets the receiver sub output level at a positive number, turn the sub up and re-run the software. Continue this until you get a slightly negative number on the receiver's output. You don't want a really negative number on the receiver because then the signal level may be too low to activate the "auto-on" feature of your sub.

This will get your sub as well integrated as it can be. If you then *prefer* a little exrtra "ummph" in your bass, you can turn it up from there.

Good luck and enjoy your system.

Craig,

Thanks for the info. I've only "toy'd" around with the Audessy setup a little bit. I wasn't overly impressed with Yamaha's implementation YPAO (prior receiver was an RX-Z1). I think I'll give this a try a little later this evening. I'm also trying the free-ware program RoomEQ with my good ole Rad Shack digital DB meter to pin down speaker placement and flaten frequency response without having to electronically compenstate for it first. I'd rather get to close with speaker placement and then let Audessy perform the very fine adjustments. One of the other things I want to check on to is the decay of certain frequencies in my room. I can pin it down yet but there seems to be a range that creates a standing wave that doesn't decay as fast as the rest. What would optimal decay be for the 50-200hz range?

Thanks,

Ryan

Ryan,

I have a Yammy receiver, (RXV4600), with YPAO and I agree that I'm not enamored of the EQ settings. I override them and I only use the settings for speaker distance and level. However, your Audessy system is supposed to be head and shoulders better than YPAO. Read the articles I linked to above, especially the second one. Your system goes way beyond parameteric EQ, (which is all YPAO does, and not very well at that). Audessy uses time based corrections as well as frequency based corrections, plus it includes all the subwoofer frequencies, (YPAO stops at 63 Hz), plus it corrects at multiple seating positions. It would behove you to fully investigate it's potential.

BTW, those Klipsch speakers sound interesting. I've never heard them, but I have a Reference System myself, which I really enjoy.

Best,

Craig
