Q Acoustics 3050i - improving stereo performance

[Bloom@83]

recently ordered from DataVert Bengaluru (99169 52506) . the shipment is in transit.
I can provide feedback once I receive the products. you may speak to above number , I think he will be able to ship to your location.
ordered 7 meters (154/meter) + 236 Shipping charges

Thank you. Not much knowledgeable about cables. Is this bare wire or shielded ?

It's shielded cable..

Where is the shield? Those are outer pvc jackets.

Belden 8477 is not shielded. It is a loosely-twisted 12AWG tinned copper wire in a PVC shield enclosed in a PVC outer sleeve.

Yes, I was mistaken..

Glad that you found the right sound for you finally.

The easiest way to understand this is using sensitivity of the speaker. 3050i is 91dB/1W/1m @ 1KHz. Which means it produces 91dB loudness at 1m with 1W of amplifier power with a 1KHz tone. Now think of what happens if you drive with 100W amplifier. 100 times power will result in 20dB louder sound. So you will get 111 dB loudness at 1m with 100W.
Now you are not going to sit at 1m distance from the speaker obviously. This will bring in the distance law. Doubling the distance will decrease the loudness by 6dB which means you will hear it as quarter as loud. So, at 4m you will listen at 111db - 12dB = 99 dB.
99dB is unbelievably loud. I cannot imagine you will listen at more than 85 dB. So you are going to use around 40W of power per channel.
Now remember all this is based on a 1KHz tone. Obviously you are not going to listen 1KHz tone all day. The amplifiers will need more power to drive the speakers as the impedance will drop significantly at lower frequencies. It is not uncommon for the impedance of the speaker to drop to 4Ohm or lower at lower frequencies. So, the 40W power that you needed for your speaker will become 80W needed. Which may be hard for the AVR to deliver if you have more than 2 channel active at any point of time.
Hence the suggestion was for you to crossover higher so that the heavy lifting for the lower frequency can be handled by the sub-woofer instead of the AVR.

I think at this point you can do few things,
a) Listen at lower level. Remember every 3dB reduction halves the amplifier power.
b) Offload lower frequencies to sub-woofer. That may still be not enough
c) Add an extra stereo amplifier to drive your fronts. It may or may not be possible unless you have a pre-out in your AVR
d) The most obvious thing for an audiophile BUY a newer beefier AVR

Hi,
I’m hoping to get help here.
I’ve been trying to get my living room audio setup right, but I’m running into some serious issues with the sound quality.

Here’s my current (assorted) setup:

• AV Receiver: Yamaha RX-V577

• Front Speakers: Q Acoustics 3050i (2023 model, bought used recently) - UCINNOVATE cables with banana plugs

• Centre Speaker: Q Acoustics 2000Ci - Amazon basics cable​

• Subwoofer: Celestion S-80 - Amazon basics subwoofer cable

• Television: Sony Bravia 8 (2024 model)

I’ve attached a picture of the setup for context.

The Layout • TV is on a central stand • The 3050i floorstanders are on either side of the TV, about 6 inches from the TV stand • I’ve angled them inwards (toe-in) and tried moving them forward/backward slightly

The Problem

Despite the excitement of bringing home the 3050i speakers, the sound has been pretty underwhelming:
• Vocals and midtones are muddy — Midtones are not giving that beat.
• Bass feels boomy or weak depending on the content — not punchy or tight
• Overall sound lacks detail and clarity — it’s loud but doesn’t have that full, immersive feel I was hoping for
• No real “wow” factor, even with decent content

What I’ve Tried So Far
• Adjusted speaker positions
• Used both optical and HDMI ARC for TV-to-AVR connection.
• Played music via YouTube on TV, AirPlay (Amazon Music, Apple Music)
• Reset the receiver, ran YPAO calibration with the mic.
• Tweaked crossover and level settings manually.
Picture attached with the AVR settings for distance. (revised after the calibration as well)

Still, the output just doesn’t sound right. I feel like something is fundamentally off in either setup, matching, or calibration. I’m even beginning to wonder if the 3050i speakers are the right match for this AVR/room. I feel the music or when listening to songs, it is more dim or not that wow experience when compared to movies.
Sofa is just 3 meters away and can't really enjoy the experience sitting there.

Any advice would be greatly appreciated. I’m happy to provide more pics or test configs if it helps!

Thanks in advance! – Santosh
