Am I being to demanding od such a cheap sound bar?
No, you have the list of wants and also Mrs h requirement (which my experience would be a big factor)
Mrs Hysteresis has a big issue with a sub woofer both in size and wiring requirements so I would need to have any sub woofer in the sound bar.
So you can eliminate the separate subwoofer
You need to have large speakers for base , hence the subwoofer, so as you have said, you need to look for a soundbar that has larger speakers available also note the bass is not directional , hence why a subwoofer seperate box works. One of the tricks of the 70';s was to introduce a bass radiator, this enable a much smaller speaker to produce a better base response. And the TCL had those as did the soundbar recommended by @Lucid
, any reason you did not include Yamaha SR-C20A on your shortlist,
it looks very good on youtube and also on the reviews , and sold via RicherSounds , which is a very good Audio/TV outlet. - I have always found those guys to be really helpful, great advice, when i used to advise people on TV's Hifi , etc a few years back, they have good service and also provided a lot of aftersales support. At least the ones near where i used to live. They may have some soundbars on display, I have known them to setup the sonos system specifically to display and review in the past.
Looking at things like the manufacturers website, youtube and amazon reviews
Hisense HS 214 2.1
Looking at the reviews , and youtube , this seems like a good value bar - it has Arc , the light at the front might be annoying
But the subwoofer at the bottom may make it sound a bit better than a sound bar without one, although to get bass you need to move a lot of air and need the size, hence why the subwoofer are separate in a bigger box.
80W power - wont go into all the different ratings - but the only real value to compare is rms -
Samsung HW S60s, - Not sure if this was a typo and the s at the end should be an A , as i could not find an S
Samsung HW S60a - well over budget £350
Not a great comparison, but on youtube, played through my TV and Sonos bar theis did not sound great compared to the others
Also it does not seem to have a HDMI input - just optical or 3.5mm jack, so you would need to use the optical o/p and i assume as no cables are supplied you would need to buy a cable - also make sure the TV has an optical audio out
Personally out of the 3 i probably would not look at this one.
TCL TS 8111
I think this one I should
be quite good, looking at the speaker system, it uses an auxiliary radiator as well as a base speaker, which was introduced i think into the hifi market in the 70's to get better base - celestion I think introduced it, and i know then some of the smaller boxes produced some nice hifi results.
The front illuminates with words, may annoy me, but they might go off after a short while and setting i could not see.
so from your list - this is only a personal idea, and I would still recommend listening to them in a shop if you can possibly get a comparison , unlikely though
i would want to listen to the TCL TS 8111 , simply to see if the Base Aux radiator made any difference and what the tone was like overall
Then the Hisense HS 214 2.1
With regards to sync, I could not find out if they had a facility to change the delay, more expensive bars do have that settings, i know the sonos does, as i have used it.
has asked, Do you have a Richersounds in your area ?
mentioned the Yamaha SR-C20A https://www.richersounds.com/yamaha-src20a-black.html
Which also has the Passive Radiators for base - i would certainly add that to the list
Dimensions WxHxD 600 x 64 x 94 - so under your height of 94mm @64mm
also mentioned the HDMI Arc will not actually turn the unit off , when the TV is switched off. However, I think the Yamaha has HDMI-CEC, which not only allows the volume to be controlled from the TV remote , but it also switches the unit OFF - just read in one of the reviews on av forums , but I dont think the HDMI cable is included in the box.
Also do not assume all the cables needed are supplied - you may need a HDMI or Optical cable as mentioned above.
Not sure if any of that helped you at all
