Introducing the Sierra-LX!!!

[JCFLORIDA]

A few months ago, I upgraded my LCR from 340SE's to Sierra LX's (in a 5.1.2). Room is 10"x14', 9' 6" height. LCR, etc... is on short wall, SW behind sofa. Fronts are 8.5' from MLP. Mostly used for movie watching. I recently changed positions of speakers and added port "S" plug to them as they were sounding a bit boomy and dialogue wasn't as clear. Currently left speaker is about a foot from side wall and 18" from back wall. Right speaker is same distance from back wall and open to room entry doors further away to right. Doors are closed during calibration. Center is in open cabinet same distance to back wall.

I ran Audyssey MultEQ XT (app), sets LCR to 40Hz, SL/R 250hz (small Min22), Tops 150Hz. Running at reference mode, no DEQ or DV. I placed a 500Hz frequency range curtain.

Had a question with what folks do about setting for Midrange Compensation (MRC). The before correction graph shows a dip at 2k Hz for LCR and tops but not surrounds. So, I enabled MRC for all except the surrounds. Sounds pretty good. Haven't listened with it off yet.

I don't use MRC. I'd suggest trying a crossover of 60Hz to see if that sounds better. I also use the $20 Audyssey app to only calibrate frequencies below 300Hz for my LCR. I do full range calibration for my surrounds. That sounds better to me.

Thanks for your response. I played with the 60hz, and full range correction for surrounds. Still prefer the 40hz in my room, definitely like the full range correction on surrounds.

MRC is what creates that dip at 2kHz, it is a throwback to the old BBC curve and is something the engineers at Audyssey think makes a speaker sound better, at the sacrifice of accuracy.

I do not recommend enabling MRC for any of our speakers.

Also important to note that the curve you see after enabling Audyssey is simply a predicted response, it is not an actual measurement.

Dave,

Thank you. Will do.
