1 channel vs 2 channel driven produces diff watts at diff ohms...... this is common for japanese AVR which there will be a drop of power if you connect more speakers. For eg. x1600h rated 80w for 2 connected speakers.. if you connect more like 5.1 or 5.1.2 then you will experience even lower power output to these speakers. Therefore, its wise to get the best AVR you can afford if you are going for more speakers setup later. If you are getting a x1600h now when u have 7 speakers later you can consider an upgrade of AVR too.

80 dB @ 2.83 volt / 1m is harder to drive than another speaker that produces 200 dB @ 2.83 volt / 1m since the same 2.83 volts only produces 80 dB at 1m if you notice 2.83 v and 1m is the static figure for audio industry.. its just like compare fuel consumption for car.. driver 60kg travel 100km then give u a number of fuel consumption.. all manufacturer uses the same voltage and distance then u will have the reference value call sensitivity to refer to. But dont trust this number 100%, some manufacturer picks the high db for the most effective frequency range and show u the number. Other recommend you buy high sensitivity speakers so that you wont spend too much on the amp power...200db is too much normally ranging from 80db to 95db that is common.

had revised my reply to your post.. i put in some details for you to understand better.. hope that helps.

i think SSJBen had reply most of your question d.
for nominal impedance you do not have to worry too much about it as most of the modern AVR does support 4 ohm to 8 ohm. You will be fine with it. Sensitivity like i said is just a reference value like the car fuel consumption. For reference but dont 100% trust it. Its not the end of the world if you are getting a 85db sensitivity speakers.

Can I say if I'm doing a 2.0 (2 channel driven setup), and I pair the Denon AVR-S960H which can do 90 W at 8 Ohms with the Wharfedale Diamond 12.2 which has nominal impedance of 8 Ohms and recommended power of 20~120W.. i would say it will be totally fine.. even you are driving it with 200W amp you will be fine also.. Unless you are cranking at 90% and above of the vol all the time..

If in the future I expand the setup to 2.1, 5.1 or 5.1.2, there will be even less power since the power is now shared among more speakers, will it cause under power issue? Yes. the common problem with entry level AVR. When you connect more speaker you feel the vol drop. You need to play louder. Thats why its recommended either:
1) buy a cheap avr and connect 2.1 for starting and upgrade it when you are changing into 5.1.2 or 7.1.2 or 7.1.4
2) invest on the best avr you can afford, you can start with X3600h/X3700h. The reason i recommend this is due to its preout function that would allow you to add external amplification in case you need it in future. Any model lower than that doesnt gives preout function. Another thing is about is MultEQ XT32 with gives better sound enhancement over its lower end siblings.

Also, if the 2 polar of the speaker cable connectors touch, it'll short circuit the AVR/speaker? I just found it out holy cow
connector normally dont touch but your bare wire will touch and short circuit.. some AVR got the self prevention mechanism what will shutdown if it detect short circuit. use banana plug to prevent this.. i also have similar issue when i started my HT journey.. imagine so many speakers wire connecting to AVR and being placed so close to each other..

not ideal but u should front height is sometime better than elevation (reflective) one.

do average using phone.. if ur phone manage to match 3 or 4 speakers with the same db says 73db then u just make sure other matches 73db..

no need to match 75db.. if your audyssey work well and you did your placement correctly.. most speaker should fall around the same db.. only 1 or two speakers need to be adjusted.. thats all you need to do.. no need purposely reduce to 75db.

this type better.. less reflection.. even tripod itself will reflect sound to the mic

yup.. life is not perfect isnt it?

pb-1000 pro even better...

enjoy bro

finally.. been hearing this for sometime but totally have no idea if Malaysia dealer is going to do the upgrade for malaysia customer...
also are they going to provide a HDMI adapter to fix the hdmi issue like 6700h or 4700h?

yup correct.. but my wondering point is:
x8500h board is to upgrade 4k to 8k to ensure that x8500 throne remains
so the problem here is if the x8500ha board possesses the same flaw like 6700h or 4700h that require another external adapter to fix?

Just don't get onkyo for the time being.. the company lately seems undergoing business changes... their customer service sucks also.. 😕.. the 3 that you had listed are reasonable.. myself I m using Denon x2000 the entry audyssey capable unit but limited by future upgrade as they don't allow preout except for zone 2

I agreed with SSJBen that if you r planning to upgrade LCR you should focus on that first.. that is where most of the sound come from.. others are just addition.. you got a nice ceiling or reflection speaker which do maybe 10% to 30% of the movies playback but you are not happy with your primary which do 80% of the job.. you want to reconsider bro..

wait a boss.. let me do some saving first.. by the time i got my money ready maybe denon is launching A1000 anniversary edition

yup get your subwoofer too if you havent got it.. surround and ceiling can come later..

yes avr normally doesnt comes with speakers. Speakers are sold seperately. Looks like you wanted to reused the samsung speakers. Basically you need to check your cables as these home theater set normally comes with the fool proof connector. Those might not work with your avr. But as long as your samsung speakers are passive ones and has only red black connect.. it may work. Also you cannot use back the subwoofer. So you may need to invest on an avr and a subwoofer. As long as you dont crank those speaker too loud i guess it can work for the time being.

enjoy bro

i dun recommend active speaker + avr as combo

u can look for avr with multichannel preout.. if denon look for 3000 series and above.. hook your speaker using rca to amp.. so it can work normally like how the signal with go thru power amp. *might work this way but i never try before or never come across anyone doing this..

Unless you plan to place your speaker (all 4 of them) very close to the avr.. if that's the case you only need 2 no need 4.
If you plan to place your 1 pair of speaker as surround speaker, you need to consider if your power point and ur rca cable.. 1 thing bad about rca (unbalance) connection is they tends to be noisy if you run them for too long. You need to then invest on shielded RCA cable for longer run.. those cables can be expensive..

unless your speaker allows balance input (like mic connector also called XLR) else try to prevent from running long rca cables. Having said.. if you want to have balanced connectivity then its going to another level in HT. Only those high end AVR provides balance out.

Not to mention later point that you need to do audio leveling when you run your AVR calibration.

What active speakers you are using?

If you are serious about having an AVR might as well start investing passive speaker as well.. you need a center speaker also.. center is considered as the most important speaker for HT
