Side/Rear Surround Calibration

ScottyDugs

After running audyssey, my side surrounds were set to 100Hz crossover and my rear surrounds were set to 40Hz crossover...does that seem strange to anyone?

Yes. I would probably re-run Audessey,and make sure it is extremly quiet. I think your sides may have a bad reading. If there is no change, consider raising the rears to 80 Hz. Your sub should be able to cover that bass, and free up AVR power.

Ok. do I have to do all 6 positions or can I just calibrate one seating position. I only watch from one spot

1. Audyssey is detecting the in-room response of the speakers... so even though a speaker may be spec'd to go down to 50Hz, if your room is causing a major suckout of sound at 100Hz, it's going to read that speaker's cutoff point as 100Hz. That can only be fixed by placement.

2. Despite your LS/FX's spec'd lower -3dB response of 50Hz, it only has 4.5" drivers... so honestly, 100Hz isn't an awful measurement there. The baffles aren't angled the way current FX series speakers are, so the audio at the seats is largely reflected. The RT/FX has larger drivers and a larger enclosure, so go figure that they were detected at a bit lower frequency.

3. Always do as many positions of Audyssey as your AVR has available. The more data you feed it, the better it can equalize for your room and listening area. If you're only concerned with one seating position, do center, a foot to the left, a foot to the right, then mimic those positions a foot or more forward. Variations in the sound can occur from inch to inch in that space, so more data about that space should give a better generalized equalization.

ok thanks

Turned out I had the wires wrong behind the driver of one of my LS/FX...I recalibrated with audyssey and it set it at 60hz...much better....its strange though because when I first ran audyssey it never told me that there was a phase error...but this time it warned me about the error.
