Hi keith , I need some help in setting speaker levels in my XMC-1. I've pair of TektonDesign - Double Impact tower speakers and per Tekton its 98db sensivity and i'm using radio-shack Spl meter. I am measuring speaker levels using XMC's 75db test tone, front left/right speakers is at -12db but still my SPL meter is showing 80db, I've a SVS PB13 subwoofer, volume in the subwoofer is set at -10db, XMC subwoofer level is at -1.0db and my spl shows 75db How do I measure all speakers level at 75db? Should I target for 80db instead? When do we use 65db (low) testone in XMC? Thanks |

Iam having XMC-1, Running Left and Right speakers Polk Audio LSiM 707 and XPA-5 for centre speaker LSiM 706c and 4 surrounds with KEF Q2ds. I didn't have any problems with left and right also surrounds..
But, always problem with centre speaker which is blowing tweeter atleast twice a year. Kindly help me.. what is Q settings and crossover.
Cheers

If 80 works for you then use 80. The different test tone levels are there for you to use whichever you prefer to use. I use the 75dB tones myself. There are too many variables to try to reach the absolute levels of the tones. Speaker sensitivity, amplifier gain, room etc. |

There are too many variables to try to reach the absolute levels of the tones. Speaker sensitivity, amplifier gain, room etc. Thanks geebo. My speakers are high sensitivity(4Ohm, 98.82dB 2.83V@1m) and drive them using XPA Gen3 amplifier. Given the high sensitivity of speakers should I use 65db pink noise to set levels? Why I'm particular about pink noise is because i don't want to damage the speakers. Assume I set my leveled my speakers using 75db pink noise and I'm playing content with main volume -20db, -20db main volume which i guess is bit loud. With this is there any chance of damaging equipment at peaks? Thanks |

With this is there any chance of damaging equipment at peaks? Thanks Use whatever test tone levels that are comfortable for you. All you're doing is setting the relative levels. You just need to have the test tones play loud enough over the ambient noise levels of the room. With those speakers 65dB should be fine. The absolute volume setting is not all that important and when you set the levels higher than the -12dB that you have them at now the volume setting number will be lower for the same listening level. With your setup your ears will likely bleed before you cause equipment damage. Are you using Dirac? |

Yes sometimes I use Dirac, but in Dirac even though I set my speaker levels and after DIRAC process is completed I see all speakers are set back to 0db. Is that a issue? |

Yes sometimes I use Dirac, but in Dirac even though I set my speaker levels and after DIRAC process is completed I see all speakers are set back to 0db. Is that a issue? That's exactly what Dirac will do. It sets all the speaker levels to what it thinks is correct and then sets the number to 0. After running Dirac I go into the Dirac preset and check levels using the 75dB tone and read the left front channel. I then go around the other channels and match them to the left front. Usually only small adjustments of 1 or 2 dB are needed if that. |

There is also an internal trim level that you could reduce 5 db if you really want them to hit 75 db.

The test tone being rated at 75 db is totally irrelevant. The objective is to equalise the speaker volumes, it doesn't matter if they are equal at 65 db, 75 db, 85 db, or 95 BD, etc what is only important is that they are equal. Since I have to stay in the room whilst adjusting the balance I tend to use around 70 db but that's just for my comfort, there is no technical reason for choosing that volume. The best method I have found us to aim for the smallest correction, so I don't pick the softest or the loudest speaker and try and match to it. I pick a mid point speaker and then up and down adjust the others to align with its volume. With the preference to adjust downwards more often that upwards. Big upwards adjustments should be avoided as it can lead to overdriving that speaker alone.
I assume you have already set the speaker distances, if not then do that first, before correcting the volumes.
Happy New Year to All
Gary

Kindly suggest me for my XMC-1 to set crossover settings for my speakers.
Thanks

Start at 80Hz and see how you like it. Feel free to adjust from there to suit yourself. Going much higher might cause the sub's location to be heard which is something you won't want. Going down from 80 is fine if your mains have better bass in that region than the sub.

It's pretty much like every other preamp/amp or pre/processor- you want the distance's of each speaker to MLP(main listening place) set then level match 75/80db to each speaker to MLP . movie sound tracks have a set standard to go buy but music does not. as long as distances are set first then levels 70 to 85 you should be good to go . most quality speakers will do good with this practice

Thank you Gregory,
But, what about Q, wide range..?
Also, my main's are LSiM 707 and four surrounds are KEF Q2ds. Kindly suggest me.
Thanks.
