Hi,

Im in need of some help with my system and find i get uneven results from Audessey Multieq XT on my Onkyo 876 and Quad L-ites 5.1 speaker package.

Specs for the speakers are...

Sat Speakers
30-120w
6 Ohm
sens 86db
freq response 70hz-24khz
crossover 2.2khz
freq Fb 70hz

Center Speaker
30-150w
6 Ohm
sens 87db
freq response 80hz-24khz
crossover 2.5khz
freq Fb 75hz

Powered Sub
300w
line in sensitivity 250mw - 100w
freq range 25hz-95hz
Low pass filter 35-85 in 10hz increments
input impediance 10k

I have the sub "low-pass filter" disabled and audessey auto setup comes up with the following...

Center speaker is low down (under main display), so have angled it up to point at ear level.

Audessey results...

Distances are correct.

Speaker Config
===========
Front (sats) - Full Band
Center - 100Hz
Surround (sats) - 80hz(THX)
LPF of LFE 80Hz(THX)

Layout is ..

DISPLAY TV
L-C-R
SUB



RL-SOFA -RR
Rear wall

Sofa is right up against rear wall due to room


Test positions are

4-5-6
7-8
3-1-2

1 being the center seating position/central to center speaker (measurments taken 2ft from rear wall/back of sofa)
4,5 and 6 being just in front of the seating area
7,8 taken at diaginal centers

Testing with supplied mic on boom stand, no ambient noise and i am not in the room when measuements taken.

Can anyone advise on correct crossover settings etc... i have read that all sats should be set to small and believe my front sats are been set to large possibley due to higher base reflections from the rear wall, however you should not lower xovers but you can increase them, so a little confused on what i can do to level out the settings, put them all on 80Hz (THX) and leave center on 100Hz?

Thanks for any help.

Correct .. the latter .. raise the FL/FR to 80Hz and leave the center at 100Hz. Also the LPF of LFE setting factory defaults to 120Hz and should be left at that setting to allow the full LFE signal to pass to the sub.

Thank you,

Even though the sub is rated up to 95Hz, i should still set it to 120hz?

If you've got a subwoofer none of those speakers should be set to full band, especially not satellites.

Looks like the satellites have a 4" woofer and 1" tweeter. setting them to 80hz is probably optimistic and I'd set the crossover to 90hz. I think your Onkyo can go in 10hz increments. But try both settings and decide which sounds better.

I think the LPF for LFE should be set to 120hz.

Right now you're using the standard THX settings which sets everything at 80hz. That's not necessary correct for satellite speakers.

Ok i'll try that,

I have also noticed in the equalizer settings it has selected Audessey - Dynamic EQ, should this not be set to MultEQ XT?

Thanks.

Audyssey MultEQ XT is the primary EQ program (may only display as Audyssey) while Dyn EQ and Dyn Volume are sub programs that are available for use as well.

In the speaker setup menu - equaliser settings, i am able to select between - MultEQ XT, Dynamic EQ, Dynamic Vol (Light), Dynamic Vol (Heavy), OFF and Manual.

Initially it was set to Dynamic EQ, so i have now changed this to MultEQ XT.

Select whichever setting you most prefer, however, the Dyn EQ setting is what is recommended for all sources all the time as it helps to boost the bass/surround audio at lower (below reference level 0db) volume levels. The Dyn Vol (Medium) is suggested for late night movie viewing when others are asleep or to tame the loud obnoxious commercials during cable/sat viewing. Note also that when Dyn Vol is used Dyn EQ and Audyssey are both enabled, and when Dyn EQ is used again Audyssey is still enabled which is why the settings are worded in the order you listed.

After studying the Aussessey setup guide, i did find that i was taking tests too close to my rear wall and so i have run a full re-test (8 Point) with my MLP 2ft from the rear wall and get the following better results...

Front (sats) 70Hz
Center 100Hz
Rear (Sats) 80Hz(THX)
LPF 120Hz

However with this result explosive/louder scenes seem too loud/bassy, the missus then turned the volume down but when there was just dialogue it was too low to hear what was being said, so i's still not right yet!

Do i set all my sats to 80Hz(THX) or 70hz and decrease the sub power level which is currently at +3.5db?

Thanks.

Your speaker crossovers are fine as is ... no reason to make any adjustments. Try turning Dyn EQ and Dyn Volume to ON.
