REW - Help needed !!!
« on: July 01, 2017, 13:37 »
Hi friends, starting my journey to improve my home theatre experience by finding out the optimum performance I can get from my system.

I have got rew configured with macbook/hdmi. What should be the first thing I should measure?

I intend to improve the overall system as it is not impactful.

Most of the guides seems to be focusing on how to configure REW and not how to use it o calibrate the system, appreciate gurus  help here. Pls let me know if there is an existing guide available that I may have overlooked.

Can you share some details of the setup, gear, room placement etc? Do you have audyssey? How is effect pre and post calibration?
What are you missing, impactful in terms of bass? Or mids highs? What subs, how many, and how are they placed?

This will help get us figure out what you are seeking.

Bro are u using audyssey to calibrate & setup? How is your current calibration process w/o rew?

Rew - at a basic usage level, usually useful for
- checking what your room eq does
- integrating multiple subs and find position with least modes.
- integrating speaker with sub to check if there are cancellations

I have EQ the system with Audessy already however i presume audessy has its limitation and REW will help improve the system further.

Bro,

I am targeting 1 & 3 and in addition carry out some room treatment BEFORE investing into more equipment.

Measurement looks pretty good at first glance. What is the missing impact? For room
 treatment, what kind  do you have in mind? Recommend big rockwool or fiberglass based traps, like Aural-Aid or Gik Acoustics etc. Those foam wedges don't really absorb much in the bass.

Not impactful bass (especially in music) it is tight but not enough if you know what i mean :-)
high frequencies tend to sound a bit harsh (i think the curtain helped with them since i have glass window facing the speakers....

Soundstage does not sound big... usually a bit small, need to crank up the volume a fair bit to make it sound enough

The sub FR would sound flat and lifeless to my ears.

The 60-90hz region seem to be 10dB louder than the other lower freq. Yiu can try to tame that region and see if that suits your taste.

Next point is the LCRs are producing bass that could cancel bass from the sub. Make your your mains are set to small speakers for optimal bass  management and minimal bass cancellation.

Could u list down here, right after audyssey calibration, what steps u did to fine tune the sound?

Eg turn off dyn eq, increase sub channel volume,  increase surround channel volume etc,set to small etc.

Thanks for the comments bro

I checked the system and LCR are configured as small....not sure why would they produce Bass.

HOw do i tame the 60-90 hz region?

Reduce the sub's cross over frequency knob  and measure. Repeat until that wideband peak is tamed. Don't be surprised if you have to go to the extreme minimum x-over freq.

In addition to small LCRs, Make sure to set subwoofer mode to LFE only.
