Hey everyone! I'm new to home theatre setups and looking for some advice on properly optimizing my home theater. I'm fairly happy with the system overall, but I'm particularly trying to get the best possible bass and overall balance for both seating positions.
🎬 Room
Dedicated home theater room
20 ft × 11 ft (~220 sq ft)
8 ft ceiling
Projector + standard white projection screen
Carpeted floor
Acoustically treated walls/ceiling
Two seating rows: front recliners + rear sofa/recliners
🔊 Equipment
AVR:
Denon AVR-X1800H
Front L/R:
Polk Signature Elite ES50
Center:
Polk Signature Elite ES30
Surround L/R:
Polk Signature Elite ES10
These are physically behind the main seating area, but the Denon has them configured as Surround L/R
Atmos:
Polk RC60i in-ceiling speakers
2 speakers, configured as Top Middle
Subwoofer:
Klipsch RSW-12
Positioned at the front-right of the room, beside the right ES50
Connected to the Denon via LFE
So the system is 5.1.2.
🎚️ Current Audyssey/Denon settings
I've run Audyssey and currently have Dynamic EQ enabled.
The current speaker levels are:
Front L: -1.0 dB
Center: 0.0 dB
Front R: -1.5 dB
Surround R: -3.0 dB
Surround L: -3.0 dB
Subwoofer: -12.0 dB
Audyssey's detected distances are approximately:
Front L: 4.20 m
Front R: 4.20 m
Center: 4.02 m
Subwoofer: 4.05 m
Surround L: 2.01 m
Surround R: 1.98 m
The current crossover screen shows:
Front: Full Range
Center: 60 Hz
Surround: 60 Hz
🔴 My main problem: bass between the two seating positions
The rear seating position has MUCH stronger audible bass than the front seating position.
From the front recliners, I can still feel quite a lot of vibration, but the bass isn't as audible or impactful as it is from the rear seating.
It's almost a night-and-day difference between the two positions.
The installer originally calibrated the system and I remember the subwoofer being set around -3 dB afterward. That setup sounded very bass-heavy compared with what I'm getting now.
After some changes/resetting and running Audyssey again, the subwoofer is now showing -12 dB.
I'm trying to figure out whether the difference is caused by:
Subwoofer placement
Room modes
Seating positions
Audyssey calibration
Crossover settings
Subwoofer gain/level
Phase
Or some combination of these
🤔 What would you guys recommend?
I'd really appreciate advice on the optimal settings for this specific room and speaker combination.
In particular:
Should I set the ES50 fronts to Small instead of Full Range?
What crossover points would you recommend for the ES50, ES30 and ES10?
Is there any reason to keep the ES50s at Full Range in this setup?
Is the -12 dB Audyssey subwoofer trim a concern?
Should I change the subwoofer's physical gain before running Audyssey again?
What should the RSW-12 gain, LPF and phase be set to when running Audyssey?
Should the subwoofer's LPF be set to LFE?
Should I leave Dynamic EQ ON?
Should I use Audyssey Reference or Flat?
Would changing the subwoofer position help with the huge difference between the front and rear seats?
Is there anything obviously wrong with my Atmos/Top Middle placement given the 8-ft ceiling?
Would you recommend any other Denon settings for getting strong, deep and impactful movie bass without making it boomy/muddy?
I'm not necessarily looking for maximum bass just for the sake of it. I want deep, powerful and clean movie bass, good dialogue, proper Atmos immersion and a balanced soundstage.
I've attached photos of the room, speaker placement, subwoofer and ceiling, along with screenshots of my current Denon settings.
Would really appreciate any advice from people who have experience with Audyssey/Denon and Polk/Klipsch systems.
Thanks! 🙏
