I'm not an audio wizard; just a ham and egger who loves to tinker with sound. Much of my background has been in mobile audio, a totally different animal. Could really use some advice on speaker placement and wtf happened when I switched to XLR. lol I just added the Emo XLRs in the chain of Oppo 105 to XSP-1 to Parasound A21. Speakers are Paradigm Studio 100 V5 and a crappy little 10" Velodyne sub Just swapped to XLR and the bass dropped off dramatically and the mids (vocals especially) became much more forward. Perhaps the setup was a bit muddy to begin with. I have the Paradigms crossed over at 100 hZ and the sub at 100 hZ as well. Still have lots of room tuning to do (sub crawl etc) The room is 17' X 17' with 20' ceiling, hardwood floors but floor has nearly full coverage from wool/silk rug. Speakers are set about 9' apart ( ~18" from back wall) and 12' from the main listening area. They are toed in so that each speaker is aimed ~2' to each side of the listening area. Any suggestions are very welcomed. Again, I have very limited experience in this area. Scott  |

Not sure what is going on with the cable changeover, but 100 hz is way too high to crossover those Studio 100s! IMHO, of course.

Just dropped them to 80 and the response is favorable (more bottom end and balanced sounding) and plenty clean still. Paradigm claims they're good to 45 hZ on and 30 off axis (+/- 2dB)
Maybe play around somewhere between 60-80?
I think the sub is beginning to give up the ghost. Heat sinks are pretty warm and it's not putting out as much sound as it normally does.

I'm thinking for two channel, 50 - 60 Hz.

The XLR's run at a higher gain. I think it's plus 3 or 4 db. So if you are balancing with subs, in proportion there should be less bass for the same volume. You neeed to raise the sub gain on the back of your sub to compensate.

You neeed to raise the sub gain on the back of your sub to compensate. I think this little sub can't keep up in terms of power. Maybe it's not crapping the bed. I'll put a meter on it but I'm guessing at -40 on the XSP, it is somewhere around 70 dB or so and the sub is barely audible. The A21 gains are near 90% as I thought I read that they should be there for THX specs. Maybe I got that wrong? Don't remember... I know with mobile applications gains typically wound up around the 60% mark when level matched. Scott |

You neeed to raise the sub gain on the back of your sub to compensate. Nailed it. Thanks! I dropped the A21 gains back to ~70% and brought the sub gain up a bit. Also played with dropping the low pass on the sub and toggled between full pass and my previous settings (from XSP) on the Studios. Vastly improved sound. I think once I get the sub placed properly I'll see a substantial improvement. Got a Sound doctor disc coming and the Rat shack meter ready to go. Scott |

Most subs recommend to start a crossover at 80 and experiment REGARDLESS of 2.1 or 7.1 and REGARDLESS of how low your mains speakers go I have found that most systems sound best crossed ar 80hz

You neeed to raise the sub gain on the back of your sub to compensate. Truth. I switched over to all XLR for my stealth 6, and one cable wasn't long enough for my right speaker so I left it unbalanced. Speaker was definitely down about 6db and had to be compensated up for the meantime. Subs also had to be boosted to establish a rounded sound. |

Glad to hear it was a simple fix! IF you are looking for a good sub, power sound audio's entry line will rock your world. Seems like I have 2 choices at this junction. 1. Get 1 or 2 subs to balance the room/sound. Room is 17' square with hiiiigh ceilings. 2. Replace Studios with a larger speaker and bypass subs altogether Hard part will be the inability to audition many of the speakers I'm interested in, in my room. I've been wanting to hit the Legacy showroom to give a listen for some time but I hate the fact that I won't be able to listen to them here. I'm sure there rooms are exceptionally well setup and probably not anywhere near the dynamics of my room here. Which is to say, virtually void of acoustic treatments other than full room carpet, drapes and massive seating area. (made from fluffy cushions and cheap micro fiber surfaces [kids] ) Scott |

Glad to hear it was a simple fix! IF you are looking for a good sub, power sound audio's entry line will rock your world. Just ordered 2 - XS 15s with Anti from PSA. Very helpful folks to deal with and they're running a sale on them currently ($50 off) plus they threw in another $200 off for the package deal. Looking forward to hearing what they'll do in this room. Scott |

The specs on them are pretty impressive but I'm very curious to see what a good setup + running the Anti will do to balance the sound.  Chatted with Tom and he took the time out to go over a lot of info with me; room setup, what my goals were etc. That is some great customer service at a day and age where I'm hard pressed to find a retailer who actually gives a rats rear end. They're shipping from OH Monday morning!! Scott  |

Yep, Usually when I change anything that can effect signal gain, and subwoofer is involved, I always be sure my levels are equal output. I usually use the 75dB C weighted scale, slow response on my meter, and all is good.

Looking forward to hearing what they'll do in this room. Scott Dude, those are going to knock you through a wall. DJ They certainly bring enough power to the table to balance the bass in the room. Still playing with placement and haven't run "anti" yet. Used the Sound Doctor disc to start placement and set x-over points on the Studio 100s as well as the subs. The markings for the X-Over points on the XSP-1 are way off.... I had to dial it to the 150 hZ position just to drop bass at the 75 hZ mark. That's a bit puzzling but the sound is very clean and bass on the Sound Dr. sampler tracks were killer. Scott  |
