DIY – TV Sound system

Hi

For inspiration...

For some years we had a SONOS Beam gen.2 soundbar for better TV sound but something was missing…

Could it be better?
Then I saw the Canvas High end soundbar, what a system! https://canvashifi.com as you can see later Im ussing al most the same drivers but they where the same as in my kitchen system …

Lyngdorfs way: https://steinwaylyngdorf.com/steinway-sons-model-s-soundbar/

Both will breaking the bank so why not do it the DIY way?

Have been here before with my Kitchen system 4 years ago: https://www.diyaudio.com/community/threads/sonos-diy-kitchen-stereo-system.381066/

Seaching for an Amplifier and here it was: WIIM Amp!
What a great peace of an equipment, it got it all: HDMI input, Streamer, Graphic/Parametric Equalizer, Room Correction…
The equalizer part is very importend when placing a speaker directly on the wall!
I cant see how others can manage it without?

The driver selection:
Tweeter: SB29RDAC-C000-4/Fabric
Woofer: SB15NRXC30-4
Radiator: SB15SFCR-00 / Paper

SB Acoustics are very high level drivers!

First prototype using another tweeter and a simple crossover – What a bass!
Didnt expected to be so well!

Design:
From the kitchen speaker system I copied the design, just with a slightly larger cabinet as the TV system had to go deeper into the bass range with a passive unit.
The furniture look was repeated with solid oak and finger tapped corners to match the style of the living room.
I was surprised by the use of a passive unit to support the bass unit.
A passive crossover was made and no doubt that these units are easy to work with.

As TV screens get larger and cheaper.....85-100" screens will eventually give rise to a market segment of flanking slim wall mountable towers that can/will handle the duty of dedicated center channels........there's simply not a sensible ergonomic fit for a center channel so low on the vertical axis in relation to the screen.

Not sure if better Phantom CC algorithms will emerge or dual center channels that would cross fire in front of the screen and the viewer.
 
Congrats! Seems like a nice, straightforward solution. 👍😎 I might borrow your design for a friend or 2. 😉

Couple questions:

Does the wall add much?

Walls skinned with drywall can easily vibrate & cause problems. I've solved such problems in the past using soft rubber feet on back of speaker, and string to hang the speaker. The string doesn't tramit vibration well.

Also what of the natural bass boost for the close wall position? Do you compensate for that with EQ in the Wiim?
