Advice on how to select correct size speakers

In most scenarios in sg, our “Theatre room” size(volume) is already fixed.
It’s either at the open area living room or a dedicated bedroom.
Thus how does 1 go about choosing the correct speaker size?

From the link http://www.audiogurus.com/learn/spea...eakers-room/85
My room is small around 880ft3.
So how does 1 select the speakers for the room?
I’m using KEF front floor standing speakers and using my AVR set the speakers to small.
And i like floor standing speakers & looking at KEF 750.
However i read that floor standing speakers are not suitable to be placed at corners of the room.
By corner, does it mean at the very right angle of the room?
How do you know that particular speaker is suitable for small, medium & large room?

Find the product's manual online and see what it says. Usually tells u how much toe in and distance from walls and to listening position.

YES

what kef speakers are you using now?

you mentioned AVR, i suppose it's for HT?

i would say in general;

bookshelf speakers should be sufficient for a small room (for reference since you like KEF Q series, this will be Q350)

small tower speakers should be sufficient for a medium room (for reference since you like KEF Q series, this will be Q550)

medium/large tower speakers should be sufficient for a large room (for reference since you like KEF Q series, this will be Q750/950)

but end of the day, your space, your speakers.

The product manual only talks about the specs, no details like toe in/distance.

Spoiler!

Yup, it’s purely for home theatre. Only listen to music when I work out on my earphones.
Currently using
Center =Q95C
Front =Q55.2C
Rear = 60s
Sub=boston ASW250

Had been googling on speakers recently.
So I’m thinking to gradually upgrade my speakers such as Front first, then Center, then rear, then sub, then AVR(when HDMI 2.1 settle down).
Now I’m considering if close eyes and get R5(atlas selling $5.6k), This $ can get Q950($2.2k)
But is the moola spent on R5 worth it.
Whether the sound from movies really make a big diff between the R5 vs Q.
The reason i have this thinking is good speakers can always remain & can use for a Long Long time. It’s the AVR technology that will change more often.

Actually you can find Kef product Owners Manual in pdf. It has some recommendations and diagrams showing distance to walls and between speakers. Most speaker brands do this for every product range. Not sure if useful for u.

Gosh... really shoot bird me.
Found it but I donít think itís possible for at all for HDB houses to have 1m from wall spacing.
Back of wall still can achieve....
Thanks for the help.

sidenote;

this is considered to me at least, at the very very corner.


personally i feel, speaker tech don't change much. like you mentioned AVR tech is moving faster, i would upgrade the AVR see how i like it possibly do some room treatment, then maybe move on to speakers.

I thought this is not really very very corner.
But bo pian cannot do much.
I wouldnít upgrade my AVR since it has TrueHD & DTSHD support & Atmos support.
Thus I want to upgrade to better speakers, phase by phase.
I thinking maybe i need to consider book shelf now too.

Oh and u may wanna upgrade to good subwoofer from subwoofer specialist brands like SVS PB2000Pro. Make sure u have the space as svs ported subs are pretty big. Ported seems to be best value in terms of power and how low their bass goes.

Itís a common problem
The desire for large statement type speakers is not matched by the size of the room..
Not just in Sg but it occurs in many places where oneís hobby budget is larger than the budget for the home..

Many just canít accept that using good bookshelf speakers is actually better and gives a better musical experience
Add that sub for better bass response

To use large speakers in small rooms, bass treatment and management is required but few have the time or commitment and most donít want to pay

i'm not sure how long the wall on the right is or what is on that side. but if it's a wall, maybe can experiment with some curtains or similar to try and see how you like it, same with the wall facing the speakers, can hang some cloth or curtains.
this doesn't really count as room treatment, but it will at least give you a feel of what it is, and it will be even better done properly.

Thumbs up

Donít want to spend moolah and later realise the room is the bottleneck for the performance of the speakers. Later heartpain cannot Koon.

Will KIV this sub, new term ported sub. I only know front firing or down firing.

Due to my room size limitations, Iím considering Kef R3. The rest of the speakers like Kef Q750 & R5 would probably block my projector screen. I still planning to place the Q50a Atmos speakers on top of them.
So right now Iím trying to find out if R3 for watching movie is ok anot.
Had measured the height of my tv console, itís just right to place R3 on it.
So they will satisfy the front, side and Center spacing placement recommendation.
Any recommended bookshelf that is good for movies & music?

Actually Iím not sure the spacing recommendation for the speaker is for.
If itís to prevent vibration or something, I can get those sound absorbing foam & cloth/curtains as you suggested to counter the effect.

Thanks everyone for your inputs.

I think some speakers with different drivers on top of each other need a certain distance for the sounds from each driver to 'converge'. Kefs UniQ design should allow closer listening distance than most conventional speakers. Also the drivers and tweeters may sound optimal at a certain angle to the listener so that may also determine the distance apart from each other and to the listener especially when they are used in a pair. That's why some instructions will tell u how much to toe in the speakers. Just my guess heheh.

In my humble noob opinion, movies don't need expensive speakers but Kef R3 should make music sound heavenly. If you only watch movies maybe Klipsch RP600M is very good already. Cost about $899/pair only. Plus the dedicated centre speaker should be cheaper too. Check out the reviews on stereophile.com
