Would have been useful to state that as explicitly as you have just done but in your opening post.My tv doesn't have inbuilt speakers it just has standard speaker connections for audio out so i8 can control vo9lume that way.7
I'm open to buying second hand
You know your stuff it's a pioneer kuro.Would have been useful to state that as explicitly as you have just done but in your opening post.
The last TVs I sold with speaker terminals were Pioneer and Loewe plasma sets from 2005~2008. Can't recall ever seeing speaker out on LCD/LED sets, and nor on OLED either.
Second-hand, off the top of my head:
Monitor Audio BX2 or Bronze 2
KEF Q- or IQ- series
Wharfedale Diamond 9.1
Dali Spektor 2
The list isn't exhaustive. There are plenty of reviews online for used speakers. Treat the reviews with a pinch of salt though. End-user reviews can be less than objective and professional reviews can be overly-nitpicky. You're really just trying to sort the wheat from the chaff and eliminate any speakers with character flaws or reliability issues.
Wharfedale Diamond 220 (£99/pr)
Q Acoustics 3020 (c. £100/pr)
Fine F300 (£159/pr)
With either new or used I would suggest keeping an eye on the sensitivity figures. Small bookshelf speakers tend to be low (82-84dB not uncommon), where as better speakers might deliver 87-89dB. That might not make much sense until you realise it could be the difference between the amp working twice as hard for the same volume level on the lower-sensitivity speakers. The amp.inside the TV won't deliver oodles of power, so it makes sense to use it wisely.
Sensitivity tells you nothing else about the performance of a speaker though. It's a bit like the mpg of a car. You know how far it will go but nothing about what it's like to drive it.
