Normally, I would set ALL my speakers to crossover to my AV123 MFW-15 Sub @ 80hz. However, I've had bookshelf speakers for close to a decade. Today, I received my ERT 8.3s and have tried setting them to crossover @ 50, 60, & 80hz.
I watch movies more than listen to music: 90/10%
My dedicated theatre measures 23' 2" x 13' 6" x 7' 7"
I am wondering what others are using in their home theaters with their subwoofers...
These babies are BEAUTIFUL!

Audysessy set the 8.3s @ 40 Hz and the 6.3 @ 70 Hz. I could probably set them all to 60. I have the LFE @ 100 Hz.

For audio only I use them at full range. For home theater use I set the crossovers at 80hz. I like my movie's loud and the dynamics would be pretty demanding on the 8.3's...so its best, IMO, to let my sub pick up some of the work.

The ERT-8.3 are truly exceptional full range speakers. I would set them to cross at which ever setting sounds best to you. Your room's acoustical properties are going to be different than any other room, so there is no best setting for all rooms. Then there is the matter of taste. Some people like their movie viewing to be very dynamic, even beyond real life levels, while others prefer a more subdued low-end.
If you want the sound from your system to approach real life, I would advise setting the xover at about 50Hz (+ or - 10Hz, depending on your room). Many people use these speakers without a sub woofer for 2-channel listening. Let your ears be your guide -- set it to what sounds best to you.

I calibrated my HT with the Audyssey MultEQ XT and the results were: Front 8.3s: 40hz Center 6.3: 50hz Surround ERD-1s: 90hz Front High ERD-1s: 70hz Surround Back ERM-1s: 60hz Low-Pass Filter of LFE set to 120hz |

No offense intended, but to me this is a good example of why I never rely on any auto room systems except for entertainment and always do a manual override.
...Low-Pass Filter of LFE set to 120hz .......... This is sort of a no-brainer since the LFE channel hits a brick wall/cliff at 120Hz.
There is absolutely no LFE over 120Hz, period. In actuality most movies have no significant LFE over 80Hz.
... Surround Back ERM-1's: 60hz .......... I own the ERM-1's, have tested them and they drop off very fast below 80 Hz. I would never set them to cross at anything below 80Hz.
... Surround ERD-1s: 90Hz .......... Bingo! one out of five isn't bad. ;D
... Center 6.3: 50Hz .......... Please, this has got to be the absolute low end for this speaker. It must be straining at 50 Hz. Why not cross it over at 70Hz or so where it is still reproducing strongly at fairly low distortion and let the sub handle from there down.
... Front 8.3s: 40Hz .......... Still way too low in my opinion. From my reading 40Hz is maybe the -3dB level at the best in many rooms or probably higher. Again why run the 8.3 down to it last legs. I certainly hope the MFW-15 is reproducing 40Hz at lower distortion than the 8.3. I would go for 60Hz.
Now, I'm going to go put on my flak vest and head for the bunker as I anticipate some incoming! ;D

Chuckienut Those are all very good starting points for setting up a HT with those Emotiva speakers. From there the OP would just need to do a little tweaking to find the settings that would best blend the various speakers together giving him the optimal performance for his room. That was very good advice for such a feeble-minded, 247 year old hobbyist. ;D Now turn on your hearing-aid, turn up the volume and enjoy that Bolero recording, and see if you can remember why you used to play that musical cut for your dates.   |

While the 8.3's certainly capable to 40Hz..why run them that low when you have a good subwoofer?? I say set them at 80hz... |

Now, I'm going to go put on my flak vest and head for the bunker as I anticipate some incoming! ;D Thx guys for your input! The settings I displayed in my earlier post were what Audyssey found to be the best for my environment, but as you guys mentioned its really up to me and my ears after various listening tests with various movies. I have manually changed my settings to the recommended THX settings (except on the 8.3s): Front 8.3s: 60hz So far I'm happy @ this level, will try 70hz next weekend Center 6.3: 80hzSurround ERD-1s: 80hzFront High ERD-1s: 80hzSurround Back ERM-1s: 80hzLow-Pass Filter of LFE set to 120hz |
